Conex box

vetsday

Today we thank for theirs service to all our military personnel and we honor our veterans. I know you’re probably asking what’s the connection between military and shipping containers, well you probably heard about the conex box, one of the many names of the shipping container.

The CONEX box was developed during the Korean War and was used to transport and store supplies during the Korean and Vietnam war. It was reinvented by Malcom McLean to form the standard Intermodal shipping container (often called an ISO box, after ISO 6346) that is used widely by container shipping companies today.

The use of standardized steel and Aluminum shipping containers began during the late 1940s and early 1950s, when commercial shipping operators and the US military started developing such units. During World War II, the US Army began experiments with containers to ship supplies to the front lines. Cargo was being delayed at ports due to the time required by break bulk loading and offloading of ships. In addition the supplies suffered from pilferage and in-transit damage. In 1948 the U.S. Army Transportation Corps developed the “Transporter”, a rigid, corrugated steel container, able to carry 9,000 pounds (4,082 kg). It was 8 ft 6 in (2.59 m) long, 6 ft 3 in (1.91 m) wide, and 6 ft 10 in (2.08 m) high, with double doors on one end, was mounted on skids, and had lifting rings on the top four corners.

After proving successful in Korea, the Transporter was developed into the Container Express (CONEX) box system in late 1952. Based on the Transporter, the size and capacity of the Conex were about the same, but the system was made modular, by the addition of a smaller, half-size unit of 6 ft 3 in (1.91 m) long, 4 ft 3 in (1.30 m) wide and 6 ft 10 1⁄2 in (2.10 m) high. CONEXs could be stacked three high, and protected their contents from the elements.[4] By 1965, the US military had some 100,000 CONEX boxes, and by 1967, over 100,000 more had been procured to support the escalation of the Vietnam War making this the first worldwide application of intermodal containers.
More than three quarters were shipped only once, because they remained in theatre. The CONEX boxes were as useful to the soldiers as their contents, in particular as storage facilities where there were no other options.

The term “CONEX” remains in common use in the US military to refer to the similar but larger ISO-standard shipping containers.

Top 10 International Container Shipping Companies

ships

As of right now, around the world are more than 100 shipping companies that are competing for a place on the market. Most powerful ones we already know them, but it’s always good to know who you purchase from and who you compete with. You can see the full top 100 chart here.

Just to have an idea about global figures, right now in the world are :

  • 6,139 active ships
  • 23,468,120 TEU

TEU stands for Twenty-Foot Equivalent Unit which can be used to measure a ship’s cargo carrying capacity. The dimensions of one TEU are equal to that of a standard 20′ shipping container. 20 feet long, 8 feet tall. Usually 9-11 pallets are able to fit in one TEU. This gives a volume range of 680 to 1,520 cubic feet for one TEU. While the TEU is not itself a measure of mass, some conclusions can be drawn about the maximum mass that a TEU can represent. The maximum gross mass for a 20-foot dry cargo container is 53,000 lb

  • 284,109,767 DWT

Deadweight tonnage (also known as dead weight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry, not its weight, empty or in any degree of load. DWT is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew.

As you can see below, who are the leaders in the business: ( the information below is based on existing fleet and overbook TEU capacity available on board operated ships )

A few details about top 5 biggest companies in the market

1 – A.P. Møller – Mærsk A/S, also known as simply Maersk, is a Danish business conglomerate with activities in the transport, logistics and energy sectors. Maersk has been the largest container ship and supply vessel operator in the world since 1996. The company is based in Copenhagen, Denmark, with subsidiaries and offices across 130 countries and around 88,000 employees.

2 – Mediterranean Shipping Company S.A. (MSC) is a Swiss-Italian international shipping line. The company operates in all major ports of the world. It is the world’s second-largest shipping line in terms of container vessel capacity.
As of the end of August 2019, MSC was operating 561 container vessels with an intake capacity of 2,621,000 twenty-foot equivalent units (TEU). It has a division called MSC Cruises that focuses on holiday cruises.

3 – China Ocean Shipping (Group) Company, known as COSCO, is a Chinese state-owned shipping and logistics services supplier company. Its headquarters is in Ocean Plaza in the Xicheng District in Beijing. It owns 484 ships, has a container fleet with a capacity of 1,564,000 twenty-foot equivalent units (TEU), and a tanker fleet of 120 vessels. The fleet calls at over a thousand ports worldwide. It ranks third largest in both number of container ships and aggregate container volume in the world.

It is the largest dry bulk carrier in China and one of the largest dry bulk shipping operators worldwide. In addition, the Group is the largest liner carrier in China. In February 2016, the COSCO Group merged with China Shipping Group to form China COSCO Shipping.

4 – CMA CGM S.A. is a French container transportation and shipping company. It is a leading worldwide shipping group, using 200 shipping routes between 420 ports in 150 different countries, ranking fourth behind Maersk Line, MSC and COSCO. Its headquarters are in Marseille, and its North American headquarters are in Norfolk, Virginia, United States.
The name is an acronym of two predecessor companies, Compagnie Maritime d’Affrètement (CMA) and Compagnie Générale Maritime (CGM), which translate as “Maritime Freighting Company” and “General Maritime Company”.

5 – Hapag-Lloyd AG is a German international shipping and container transportation company. It is composed of a cargo container shipping line, Hapag-Lloyd AG. The container transport arm of Hapag-Lloyd AG is currently the world’s fifth largest container carrier in terms of vessel capacity.
The company was formed in 1970 by the merger of two German transportation/maritime companies, Hamburg America Line (HAPAG), which dated from 1847, and Norddeutscher Lloyd (NDL) or North German Lloyd (NGL), which was formed in 1856.
Since its formation, Hapag-Lloyd has been sold to many organizations and has also undergone numerous mergers with other companies. For instance, Hapag-Lloyd was completely acquired by, and became a subsidiary of TUI AG (Hanover) in 1998. This major event was followed by TUI selling a majority stake of Hapag-Lloyd to various private investors in Hamburg in 2009 and again in 2012. Other important events in the company’s history include Hapag-Lloyd’s acquisition of CP Ships in 2005 as well as Hapag-Lloyd’s merger with CSAV in 2014 and United Arab Shipping Company in 2017.
Currently, the companies shares are owned by several public and private investors, with the largest stake controlled by CSAV.

Dimensions of the most purchased and used shipping container sizes

Did you know that around 90% of the world’s cargo is moved by ships? There is no surprise that to accommodate such a variety of goods, there are many different types of shipping containers, each used for a different purpose.

USA Containers Co. supplies new and used shipping containers in a wide variety of sizes. There are numerous designs of shipping container, but the majority are what are termed “dry van containers”, these carry general freight. We offer from the smallest 20ft, 40ft standard, 40ft High Cube, to the largest 45ft High Cube, with regular doors or doors on both ends for the new boxes. Because containers are mass produced and designed for a harsh marine environment, they lend themselves to a cheap, movable, and secure storage unit.

Wedding, save the date and trash the dress trends you should consider.

wedding container

Maybe you think shipping containers cannot create a romantic and beautiful image, but most of the time, unconventional places, can create more memories and remains in people minds for longer than traditional ones. So people have figured out a way to blend them in their wedding parties and photo sessions. We’ve seen the trusty shipping container modified to serve as pop-up retail shops, tiny homes, hospitals, and even swimming pools. Now, containers are starting to take their place on the biggest day of some couples’ lives. From portable bars to colorful backdrops, the shipping container wedding trend is beginning to make its mark on weddings and engagements.

Most people think that in order to reuse an old shipping container, they need to be stripped clean and built up with expensive new materials. One couple decided they loved the Shipping Container just as it is! And what a beautiful gallery they’ve got! They chose to use the colorful, textured stacks of steel boxes as the backdrop for their Wedding photos. They knew it would be the spot for their treasured photos and that the harsh, dirty containers create a rough, industrial look that will overlap and blend with the soft, lovely and romantic atmosphere, creating a striking image.

Are you ready to receive your shipping container?

delivery

After so many deliveries and so many questions we decided to help you with some tips and information that might help you when purchasing a shipping container. As a company that respects its customers and employees, we prioritize the safety, security and integrity of all our storage containers.

Before any site modification is made, contact your local council to inquire it is legal to do so without a permit (which may be required) – a phone call is cheaper than a fine or the cost of relocating the container.

As part of our delivery process, we inspect each container to ensure its structural integrity and security when picking them up. We also take steps to protect our crew, as well as our customers on site. This includes asking our customers to take responsibility in preparing the delivery site.

Decide on an area

Storage containers are big. Sounds obvious, but it can be hard to visualize just how much space a 20ft or a 40ft storage container will take up. Furthermore, once the container has been delivered, you won’t be able to move it on your own, unless you have the proper equipment ( crane or heavy forklift ). Therefore, the first step to take when preparing for delivery is deciding on the best location to place it, of course this after you already decided on a size that fits your needs.

To work out just where you’d like your container to go, it’s a good idea to mark out the area with cones or rope. This will give you an accurate representation of exactly where your container will be placed. Plus, it will provide you with the opportunity to check that you’ll be able to enter and exit your container seamlessly. Make sure not only that you can get into your container, but also that you have spare room for it to be unloaded from the trailer. A rule of thumb is to leave enough space for two containers for delivery. For instance, for a 20ft container, give yourself 50-60ft of room for a stress-free delivery.

Think also about how the driver should get on your property, so when we ask you, how the container should be positioned on the trailer, with the doors facing towards the cab of the truck or towards the rear of the truck, you already know the right answer.

Make sure you have enough space for the delivery truck

Think about the size of the container. The truck will need enough space to make very wide turns and to get in your property / delivery area, around, and out of the property. Make sure there’s plenty of clearance to get through gates, under tree limbs, power lines and other obstructions. We always ask about an ideal width clearance is at least 15 feet, though our drivers can work with 10.

Usually for the deliveries to go smooth for a 20ft container the requirements are:

  • 14-16 ft height clearance
  • 50-60 ft length for a straight shot unloading when they are coming on a 20ft roll off trailer, otherwise take in consideration the same length requirements as a 40ft container
  • 15 ft width

For delivering a 40ft container requirements would be:

  • 14-16 ft height clearance
  • 100-120 ft length for a straight shot unloading
  • 15 ft width

The deliveries are made on flat bed trailers or tilt bed trailers, and there could be two types of delivery methods.

1 – Drag Off delivery – also known as customer assisted unloading, inquires that the customer has to use an anchor point to help the driver unload the container. You can watch how a drag off delivery takes place in the video here.

2 – Roll Off delivery – this type of unloading has no requirements for the customer to assist the driver for unloading, it goes smooth and no stress either. You can watch how a roll off delivery takes place in the video here.

The truck will need to maneuver into the space to make the delivery, backing up and pulling in to get the right angle. As a rule, 50-60ft of depth clearance is good for 20ft containers and 100-120ft for 40ft containers, not including space for the delivery truck to maneuver in and out.

Prepare the ground

Once you’ve decided on the area that your container will be delivered to, it’s time to actually prepare the ground for the container. The most important step to take at this stage is to ensure the ground isn’t too soft. Although containers are one of the most weather-resistant and durable storage solutions, at up to 8800-9000 pounds heavy, they’re liable to sink if placed on a particularly soft patch of ground. Additionally, if placed directly onto consistently damp ground, the bases of even the most durable storage containers will eventually be damaged over time.

If you’re stuck for options and you really need to place the container on damp ground, you can consider putting down some gravel or wooden planks as a form of additional support. This also helps keep the door frames square and ensure smooth operation of both doors.  Either 4×4 or 8×8 or even railroad ties would do. After delivery you can also crank it up and put cinder blocks on the corners and sides so you can keep it off the ground level, this will allow for airflow underneath the container to dry out the surface that the unit is placed on. It will prevent the formation of condensation which leads to mold, rot, and (potentially) flooding. If you’re intending on keeping your container indefinitely, it may be worth the investment to simply pave the area where it will be stationed, this ensures the absolute best conditions for your unit.

After delivery

Once the container is in place, check the integrity of the container. Swing the door open and shut, making sure it closes easily and tightly, and ensure the locks function easily. 

We recommend to power wash your shipping container and paint it to increase it’s life and keep it’s durability over time.

How shipping containers are Loaded, Inspected and Delivered

I guess everyone has questions about how the container looks, if they can see or pick their container out, etc. The video below was made by our owner, in order to explain how the delivery process takes place and maybe answer to a few of your questions.

Most of the time when the driver goes to the depot, he gets in ( sometimes he waits in line from 30 mins up to 3-4 hours to get loaded ). He follows strictly the designated loader or goes to the loading area where he can be loaded.

Once the first out of stack box is brought down, our driver inspects the container, gets inside, checks for holes, gaskets and if doors can be opened and closed.

Once he gives his OK, the shipping container is loaded onto his trailer, he straps it for safety to his trailer, so it doesn’t flip, slide or fall off from it, and then he calls our customer to inform him he is ready and leaving his way, also he gives him an ETA ( Estimated Time of Arrival ).

Last part it’s pretty obvious, he arrives at the destination, unloads the box and returns to his garage, leaving one more happy customer to enjoy his shipping container.

Just so you know the whole process described in the video took about 2 hours, but if we are to put it on a scale from very easy to very hard, this was one of the easy ones, not to much waiting at the yard, not to much traffic and good delivery area, enough space, no obstacles in the way. Sometimes just one delivery takes up to 7-8 hours, depending on waiting time at the yard, on the way and at the delivery site.

Tips on how to choose the right shipping container

what to think about_

When it comes to building a shed, a garage, a house or any other project that you need to use it, one of the most important steps is purchasing the right shipping container.  Like we presented the types and sizes of shipping containers in a previous article, because of that and not only, container prices tend to move up and down in the market based on many factors, like supply and demand. So it’s important to know where to start, so you can get the best deals available and what to look for. Here are a few tips that can help you decide on what you need and save you some time and money.

  • Please check with town officials, if there are any restrictions or you need to obtain any permits for having, using or building with shipping containers, even if it is on your property. Make sure you get approval or at least give them a call and ask, never hurts to ask instead of getting fined.
  • Are you going to use the shipping containers for their original use, for storage, business or for living purposes? Getting clear on your purpose will make the selection process a lot easier for you.
  • Shipping containers come in a variety of sizes. Most of them are 8 feet wide and 8.65 feet tall, but they come in varying lengths measuring either 10ft, 20ft, 40ft, 45ft, 53ft long. Take the time to figure out the right size for your project needs to avoid costly mistakes.
  • All options have advantages and disadvantages. Newer models are cleaner and usually problem free however they do cost a little extra money. Used models may have some damage but can be cheaper by around 30% to 50% less than the price of new containers. If you’re on a tight budget, buying used ones might be the best option for you. However, if your project requires pristine containers buying newer ones will give you peace of mind.
  • If you cannot verify or check the container before it’s delivery, which in many cases you won’t be able to do so, because containers are stacked on top of each other and usually it’s first out of the stack when the drivers go and pick them up for delivery, make sure that the containers you’re receiving are in good condition. Take your time to check and ask about any damage, dents, patches, significant rust or any possible leaks in the unit. Make sure that the one you’re getting is at the very least wind, watertight and vermin proof. Keep in mind, that used shipping containers, may have been decommissioned long time ago and surface rust, patches, minor scuffs or dents are normal, and they don’t affect it’s structure.
  • Check the working mechanisms of the containers. These include the doors, locks, hinges, gasket seals, roofs and lower sidewall. They can all acquire some level of damage during their lives, whether in motion or stationary. Hence, checking everything is in good working order must be one of your priorities.
  • Depending on the nature of your project, you can purchase a shipping container that is wired for electricity, or that is refrigerated. Would you need easy access to your container? If yes, consider getting a container with doors at both ends or on one of the sides. Decide on modifications in advance. Some sellers of used shipping containers provide modifications, as well. For example, your containers of choice can have extra doors, windows, ventilation system, security locks and shelves upon your request and before they get delivered to you. Figure out whether it will be more convenient and cost-efficient for you to have such modifications made in advance.
  • Given their size and weight, these containers are difficult and expensive to transport from one location to another. Know the exact position where you want your container delivered and always have a plan B, just in case accessibility is compromised. Getting this right may save you a lot of headaches down the track.

We want you to know finding quality, affordable and good shape shipping containers doesn’t have to be difficult. Get in touch with us today if you need help in choosing the best type of containers suitable for your needs!

Did you know how shipping containers are made?

container factory

Shipping containers have revolutionized the way cargo is transported on ships across oceans, it helped in ensuring the safety of the cargo but has also improved the overall cargo carrying capacity. As a result, shipping containers of different types are being built and used for transporting a variety of cargo around the world.

Almost all shipping containers are made from steel and have closed-top with hinged doors. They have corrugated walls on the top and bottom sides and are welded to the rails and end frames.

How are shipping containers made?

Shipping containers are made from materials such as steel, aluminum, fibre-reinforced polymer etc or a combination of all. You can watch the video below and understand better how shipping containers are made.

  • Each shipping container starts with a big roll of steel, which is unrolled and cut into several sheets.This is done in dedicated factories with technically advanced machinery systems.
  • Surface preparation of these steel sheets is then carried out using sand blasting and priming to remove rust, dirt, contaminants etc.
  • The sheets are then corrugated to improve the overall strength.
  • Roof panels and floor braces are separately made and sheets for wall panels are then welded together.
  • Square tubing is welded on the top of the walls.
  • Once this is done, floor panels are assembled to form a floor frame.
  • Door assembly and corner post assembly are also separately prepared.
  • The door assembly is then installed on the floor frame followed by installation of wall panels.
  • The corner posts, wall panels and door assembly are welded.
  • The roof panel is then assembled and welded.
  • Priming and painting is carried out.
  • Wooden frames are varnished and prepared for flooring.
  • Once they are installed in to the container floor, holes are drilled to attach flooring panels.
  • The door hardware is finally installed along with rubber seals for watertight doors.
  • The container bottom is then made waterproof followed by watertightness testing.
  • The box is finally inspected to ensure watertightness or any other problem.

We hope you enjoyed this article and you can let us know below, if you will or already used a shipping contaier for different other purpose than it’s main one.

How shipping containers are loaded

containers are loaded

I believe everybody is asking how the shipping containers are loaded, unloaded and how they are stacked on the large container ships. This video will explain and answer all of your questions and maybe more.

Imagine when they are brought at the port / terminal with trucks or trains, unloaded and stacked in the yard or directly in the cargo ships. After many of these trips overseas containers are being decommissioned and left in the yards, for others to enjoy and purchase them so they can use them for storage, housing and many other useful projects.

Container certification and grades

I believe you always wondered as well as we are often asked what grade are the containers we sell? A, B, C?

We will try to help clarify some of the confusion you might face yourself when dealing with containers. When purchasing new or second hand containers you will come across all sorts of grades and certification acronyms. ( WWT, CW, IICL, CSC or ACEP etc ) making it all sound complicated and confusing, when in actuality, it is fairly simple.

New/ Near New / One trip

Cargo Worthy minimum standard with valid CSC Plate. Interior will be minimum 95% mark free. Floor will be clean with no transferable marks or stains, but possible light scratches from transport. Near New may have minimal exterior surface corrosion, and negligible denting. Anywhere from just landed in the depot, to 5 years old fall into this grade

A Grade

Cargo Worthy minimum standard with valid CSC Plate. Interior will be minimum 80% mark free with some scuffing or scratching. Floor will be clean with minimal transferable marks or stains, with scratches not exceeding 2mm in depth. May have minimal exterior surface corrosion, and negligible denting. Near new, refurbished and used containers fall in to this grade

B Grade 

Cargo Worthy or Wind Water Tight standard with or without valid CSC Plate. Wind and watertight. Interior will be minimum of 50% mark free, some scuffing or scratching and minor surface rust. Floor will be stained or marked and may also have minor delamination. Exterior may have more prevalent corrosion and dents. Container may have small amount of previous repairs/patches

C Grade

Structural condition of container may be Cargo Worthy, Wind Water Tight or As Is standard with or without valid CSC Plate. Interior will have extensive markings, scratches and corrosion. Floor will be stained or marked and may also have moderate delamination. Exterior will have extensive corrosion with a multitude of dents. Container may have several previous repairs/patches

D Grade

Structural condition of container is As Is standard without valid CSC Plate. Interior and Exterior will have extensive corrosion and or holes. Floor will have extensive staining and delamination. Major damaged containers fall into this grade

Salvage

These units are sold as is, sometimes are used for parts or just for the steel, because they’re missing doors, floors or parts of the walls or ceiling. They also can be torned apart or bent so they are unusable as a storage unit.

Also each grate has it’s own particularities, and can have the following acronyms.

  • IICL – Institute of International Container Lessors – an organization which groups the largest container and chassis leasing companies worldwide. The IICL sets repair standards, by which all repairs are carried out, for its members when containers are off hired. IICL is the strictest criterion out there for used containers.
  • CW – Cargo Worthy– Criterion under which a used shipping container is deemed suitable for the transport of cargo under TIR / UIC / CSC, and meets all the standards laid out in its original specification. The CW Cargo worthy standard generally implies that the container has a valid CSC. Cargo Worthiness can be certified by a third party container surveyor pursuant to a physical inspection of the used shipping container.
  • WWT – Wind & Water Tight – a criterion under which containers are literally “wind and water tight”. In short, if you lock yourself inside the container, you should not see any light coming through the panels or roof. It should be noted that this criterion however makes no reference to the quality of the understructure. A WWT container should therefore not be considered safe for the transport of cargo; unless it is explicitly confirmed it meets the CSC. WWT is commonly used to describe and qualify used storage containers. WWT + CSC = CW !
  • CSC – Convention for Safe Containers – established in 1972 to promote and maintain a high level of safety of human life in the transport and handling of containers by providing generally acceptable test procedures and related strength requirements. This has helped facilitate the international transport of containers by providing uniform international safety regulations.
  • ACEP – Approved Continuous Examination Program – quality inspection programs put in place by container owners to monitor the condition and maintenance of their containers. As long as a unit is monitored under an ACEP, the periodic CSC re-inspection is not necessary. The exit from the program under which the container was (originally) built and maintained (in case of sale) means that containers will need to be inspected under CSC in order to be approved for shipping and will have an approval limited in time.
  • ISO – International Standardization Organization – International organization based in Geneva working towards harmonizing worldwide technical standards; including those governing the construction of shipping containers.

So keep in mind when talking about grading standards it should be noted that grading is usually a company’s internal classification system and not an international standard for purchasing containers. This means, that although 2 companies could both classify their containers in terms of grade A, B, or C, it does not mean that a Grade A will be the same for both. These grading are not international standards, and tend to refer more to the cosmetics of the container rather than the structural quality.
