Container corner post

Types of Container Corner Post

• Corner Post for Shipping Container

  Shipping container corner posts are used for intermodal containers. These containers are transported by truck and rail, so more wear and tear is expected. The shipping container corner posts on these containers are thicker and more robust than regular containers.

• Reefer Container Corner Post

  Reefer containers are refrigerated containers that carry perishable goods. Due to the electrical wiring and insulation in the walls, reefer container corner posts are designed differently. The corner posts have electrical conduits for corner posts to transport electricity along the container. The insulation is also extended to the container corner posts to prevent heat transfer and keep the entire container at the desired temperature.

• High Cube Container Corner Post

  High-cube containers are taller than standard containers. The posts of high-cube containers are designed to support the additional height. The container corner fittings are also reinforced to support the increased vertical load.

• Flat Rack Container Corner Post

  Flat rack containers are open-sided and have no walls. This makes it easy to transport oversized cargo. The corner posts of flat rack containers are designed to be lower to reduce the container's height when stacked. The posts are also removable to allow for flexible loading and unloading.

• Tanker Container Corner Post

  Tanked containers carry liquids. The corner posts of tank containers are designed to withstand the additional pressure from the liquid's weight. They are also reinforced to prevent sloshing during transportation.

• Bulky Container Corner Post

  Bulky containers are used to transport large equipment or machinery. Their corner posts are reinforced to support the additional weight and size of the container. The fittings are also designed to connect to external tie-down points to secure the cargo during transportation.

Specifications and maintenance of container corner posts

Container corner posts have different specifications depending on the type and purpose of the container. Here are some general specifications:

• Material: Container corner posts are made of strong and durable materials such as steel or aluminum.
• Height: Container corner posts are usually around 8 feet (2.44 meters) tall. This is the standard height for shipping containers.
• Thickness: Container corner posts are typically 1 to 2 inches (25 to 50 mm) thick. This thickness provides strength and durability.
• Load-bearing capacity: Container corner posts are designed to support a significant amount of weight. They have a load-bearing capacity of 60,000 to 80,000 pounds (27,000 to 36,000 kg) or more.
• Connection points: Container corner posts have connection points for attaching other container parts. These connection points may include welds, bolts, or pins.
• Design: Container corner posts are designed to be strong and durable. They have a simple design with a rectangular or square shape.

Container corner post maintenance

• Container corner posts are critical for the structural integrity and safety of shipping containers. Regular inspection and maintenance of container corner posts are essential to ensure they are in good condition and can withstand the loads they are meant to support.
• Container corner posts should be kept clean and free of debris, such as mud, dirt, and dust. A buildup of debris can compromise the strength and integrity of the container corner posts, so cleaning them regularly is essential.
• Users should regularly inspect the container corner posts for signs of damage. Look for cracks, dents, or other issues that could affect their strength. If any damage is found, it should be repaired immediately to prevent further problems.
• Container corner posts should be painted regularly to protect them from rust and corrosion. Use high-quality paint that is specifically designed for use on steel or aluminum surfaces.
• Container corner posts should be kept properly lubricated. Use a lubricant specifically designed for use on steel or aluminum surfaces to keep moving parts lubricated and functioning correctly.

How to choose container corner posts

When buying container corner posts, people need to know more about the products to make informed decisions. Here are some container corner post buying guides:

• Weight Capacity

  Container corner post columns are designed to carry different weights. People should choose corner posts with higher weight capacities if they want to use them for more significant operations. This ensures proper handling of containers without damages or accidents.

• Material

  Different materials have different advantages. For example, wooden container corner posts are strong and durable. They also have a natural appearance, which is attractive. However, they can be destroyed by termites. Metal corner posts are long-lasting and secure. They also come in different materials that are suitable for various applications. Plastic corner posts are affordable; hence, they are suitable for all people.

• Size

  Container corner posts come in different sizes. The size of the posts to be purchased will depend on the container size and the transportation requirements. It is essential to choose the right size to ensure effectiveness.

• Visibility

  Some container corner posts are visible, while others are not. If people want to enhance security during the night, they should choose visible container corner posts that have reflective paint.

• Environment

  People should consider the environment where they are going to use the container corner posts. If it is a coastal area, they should choose posts that are suitable for that environment. For example, metal posts with corrosion can resist coatings are ideal for coastal areas.

• Regulations

  Different areas have regulations and standards that govern the transportation of containers. People should ensure that the container corner posts they choose meet all the necessary regulations and standards.

How to DIY and Replace Container Corner Post

Here are the steps for replacing a container corner post.

• Assessing the Damage

  First, users should inspect and determine how bad their shipping container corner post is damaged. They should also know which container corner post they will install.

• Preparing the Container

  They should remove any containers or items that may be on or impede access to the damaged corner post. After that, they should ensure the container is empty and assess that it is level. This is to ensure that the container is stable and that the replacement post will be accurately aligned.

• Shoring Up the Container

  Users should add support beams on the inside and outside of the container. This is to provide extra support and stability when replacing the corner post.

• Cutting Away the Damaged Post

  They should cut the post using an angle grinder or cutting torch once they are set with the safety measures and shoring. They should also cut the post at the top and bottom to avoid damaging the container.

• Preparing the New Post

  Users should drill holes in the bottom of the new post that line up with the container's floor. This is to ensure the new post will be accurately aligned and connected.

• Installing the New Post

  They should lift the new post into place and secure it at the top using a welding machine once they are set with the safety measures and shoring. They should also ensure that the post is accurately aligned and level.

• Connecting the Top and Bottom Rails

  Users should connect the post to the container's roof using an angle grinder or cutting torch once they are set with the safety measures and shoring. They should also ensure that the connection is strong and secure.

• Inspecting and Testing

  They should inspect the connections and ensure that the post is accurately aligned and level. After that, they should test the container to ensure it is stable and that the replacement post is functioning properly.

Q&A

Q1: Are container corner posts interchangeable across different container sizes?

A1: No, container corner posts are not interchangeable across different container sizes. Each container size and type has its specifically designed corner posts to ensure a proper fit and structural integrity. Using corner posts not designed for a particular container can compromise safety and stability.

Q2: Can damaged container corner posts be repaired, or do they always need to be replaced?

A2: In most cases, it is preferable to replace damaged container corner posts rather than attempt to repair them. Even minor repairs can be challenging to achieve and may not restore the original strength or alignment of the corner post. Furthermore, repaired corner posts may not meet safety standards or regulations.
