Understanding Steel Storage Containers

When it comes to buying steel storage containers, it is important to understand the different types and sizes available, as well as the material and durability of the containers. Additionally, buyers must decide whether to purchase a new or used container. In this section, we will provide an overview of these key factors to help buyers make an informed decision.

Types and Sizes

Steel storage containers come in a variety of sizes, with the most common sizes being 20 feet and 40 feet in length. However, there are other sizes available as well, such as 10 feet and 45 feet. Buyers should consider their specific storage needs and available space before choosing a container size.

In terms of types, there are two main categories of steel storage containers: dry containers and refrigerated containers. Dry containers are the most common and are used for storing dry goods, while refrigerated containers are used for storing temperature-sensitive items.

Material and Durability

Steel storage containers are typically made from Cor-Ten steel, which is an industrial-grade steel that is highly durable and resistant to corrosion. This type of steel is designed to withstand harsh weather conditions and is commonly used in the shipping industry.

The durability of steel storage containers makes them ideal for long-term storage and transportation. They can withstand extreme temperatures, heavy loads, and harsh weather conditions, making them a reliable option for a variety of storage needs.

New vs. Used Containers

New steel storage containers are more expensive than used containers, with prices ranging from $3,000 to $6,000 for a 20-foot container and $5,000 to $10,000 for a 40-foot container. Used containers can be more affordable, with prices ranging from $1,500 to $3,000 for a 20-foot container and $3,000 to $6,000 for a 40-foot container.

When deciding between a new or used container, buyers should consider their budget and storage needs. New containers are in pristine condition and come with a warranty, while used containers may have some wear and tear but are still highly durable and reliable.

You can consider adding security features such as lockboxes, which can protect the padlock from being cut or tampered with. You can also add additional locks, alarms, and CCTV cameras to enhance the security of the container.

Conclusion: Practical Applications and Maintenance

Commercial and Residential Uses

Steel storage containers are versatile and can be used for both commercial and residential purposes. For commercial use, they can be used as on-site storage for construction materials, equipment, and tools. They can also serve as temporary offices or break rooms for construction sites. For residential use, they can be used as backyard sheds, providing a secure and durable space for tools, equipment, and other items. Steel storage containers also provide an excellent solution for homeowners in need of extra storage space.

Care and Longevity

Proper care and maintenance are essential for ensuring the longevity of steel storage containers. Inspect the container thoroughly for any signs of damage, such as dents or rust. Ask for a history of the container and ensure that it has been properly maintained. In addition, it is important to keep the container clean and dry to prevent rust and corrosion. Applying a coat of paint or rust inhibitor can also help to prevent rust and prolong the life of the container.

1. Doors

Two door leaves are fabricated from two vertical rolled hollow sections and 2 horizontal c section members. The frame is infilled with corrugated steel paneling.

These are normally attached to the rear corner posts each with four drop forged steel hinge blades. The blades allow 270 degree opening which allow the doors to swing back against the container side wall.

(Cargo may shift during transit. Look at the container to make sure that the doors are aligned and level, both top and bottom.  In cases where the container frame is racked and the door gear will not operate correctly.)

2. Lockbox

The lock box is a steel box welded to the right hand door which overlaps a staple welded to the left hand door. A padlock, normally type CISA type 285 66 can then be attached inside the lock box through the staple and is then protected from direct attack, hindering attempts to gain entry to the container.

3. Lockrods, cam keepers, handles

Each door is fitted with 2-4 vertical lock rods to enable opening, closing and locking of the doors.

Shipping Container Lockrods

At the end of each lock rod (top and bottom) is a cam welded in place which engages with knuckles, also known as cam keepers.

Shipping Container Cam Keepers

Shipping Container Cam Keepers

The action of engaging the cams to the keepers forms an anti-racking function.

(In certain cases, often unfortunately too many, contents of the shipping container may have shifted, or containers even dropped, causing shipping container doors and lockrods to warp)

The door handle rotates the lockbar to initiates the door opening process by forcing the cams out of their keepers.  Each door handle has a door locking handle retainer that slides over the door handle when in locked position.

Wear and Tear

Shipping containers often take a beating, traveling around the world, being exposed to freezing conditions, and rust due to seawater or when the frost has melted.

During the cold season, and in freezing parts of the world, our shipping container tool can benefit the opening of frozen shipping container doors in freezing conditions and hard to open or rusted containers once the winter has ended.

Injuries often occur as a result of personnel trying to open and close difficult container doors, often the result of inappropriate techniques being used to open them.

Shipping container doors are not typical doors and there are 4-5 hinges per door.  The hinge pins must be lined up correctly for the doors to be free to fully open and close.

Here are some likely reasons a shipping container door will not open or close.  Our hand leverage tool / shipping container door extension handle helps to address these issues.

  • Rust and Corrosion: The hinge pins and blade are seized due to corrosion.  As shipping containers navigate through diverse weather conditions and environments over time, they become susceptible to rust and corrosion. These corrosive agents can target the locking mechanisms and hinges, ultimately impeding the smooth operation of the container's doors. This accumulation of rust and corrosion introduces a layer of complexity to unlocking and opening the container.
  • Maintenance Neglect: Regular maintenance is pivotal to sustaining the functionality of shipping containers. The absence of consistent upkeep can lead to complications with the locking mechanisms, hinges, and seals. Without proper lubrication and care, these components might stiffen or become challenging to manipulate, thereby escalating the difficulty of opening the container.
  • Physical Impact: The nature of shipping exposes containers to a barrage of wear and tear, stemming from transportation and handling activities. Consequently, the containers might acquire dents, twists, or misalignments. These physical distortions can hinder the proper alignment of the doors, rendering the opening process arduous.
  • Uneven Placement: Placing a shipping container on uneven ground can disrupt its frame's equilibrium. This misalignment can extend to the doors, making them difficult to open or close. The uneven stance of the container introduces an extra layer of complexity when trying to access its interior.  Doors and lock rods may warp or the container frame is racked so that the door gear will not operate correctly. This may be caused by cargo shifting during transit. Look at the container to make sure that the doors are aligned and level, both top, and bottom.
  • Temperature Influences: Drastic temperature variations encountered during transportation can trigger material expansion and contraction. This phenomenon reverberates through the locking mechanisms and hinges, potentially impairing their normal operation. The impact of temperature fluctuations compounds the challenges associated with opening the container.  Water has become trapped between frozen shipping container doors, particularly relevant to refrigerated cargoes, or containers with moisture-releasing cargoes in cold weather.
  • Inadequate Tools: The task of opening a shipping container may necessitate specialized tools such as heavy-duty bolt cutters or unique locking mechanism tools. In the absence of these tools, the process can become considerably more demanding.
  • Sealing Complexity: Some shipping containers employ adhesive materials or seals to ensure the contents remain shielded from environmental elements. Over time, these seals can harden and resist breaking. Consequently, accessing the container requires overcoming this intricate sealing mechanism. 
  • The door gasket has been damaged and is preventing opening. Door gaskets are designed to present two or more fins against the structure or adjacent door. These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it from being closed. 
  • Security Enhancements: Certain shipping containers incorporate robust security features to discourage unauthorized access and potential theft. Although these features are indispensable for safeguarding the contents, they can inadvertently increase the intricacy of opening the container.
  • The Covid economy had also released many shipping containers in the world which are now often reused and the issue of hard-to-open/close used shipping containers is now a more common issue than ever.
