Essentially, shipping container corners, or corner castings, are indispensable components for the safe and stable stacking of shipping containers during transport. They comply with strict international standards, such as the ISO 1161 standard, and are carefully assembled by experts to ensure reliable connections. In addition to their crucial role in shipping, corner castings are also used in shipping container wheels, where they serve as connecting pieces to facilitate the movement of shipping containers.

What is a shipping container corner?

A shipping container corner, also known as a corner casting, is a crucial component for stacking and moving shipping containers. It is a cast iron or aluminium component designed to attach ISO twistlocks to a shipping container. Twistlocks play an essential role in the safe and stable stacking of shipping containers during transport by sea, on trucks or trains.

Where can you find the corner fittings?

on a shipping container? The corner fittings are located at each corner at the top and bottom of shipping containers, acting as connection points. Their placement ensures that various twist locks and drawbars can be connected, allowing the containers to be transported safely without shifting or tipping over during transport. This not only ensures efficient loading, but also the safe transport of goods over long distances.

What is ISO 1161 for containers?

The specifications for shipping container corners have been standardised by the International Organisation for Standardisation (ISO). The ISO 1161 standard specifies the dimensions and technical characteristics of the corner fittings, which is essential to ensure the compatibility and safety of containers worldwide. Sea container corner fittings that comply with the ISO 1161 standard are guaranteed to be suitable for international shipping and can be safely loaded and unloaded using a twist lock.

How is Twistlock secured in a corner fitting?

The twistlock is a locking mechanism that clamps onto a corner fitting in accordance with the ISO 1161 standard. The twistlock has a rod that allows it to be rotated 90 degrees.

This allows the twist lock to clamp into the corner casting. This ensures a secure and safe connection between the containers, even under challenging transport conditions.

Corner castings for other applications

Although corner castings are primarily used in the shipping industry in combination with shipping containers, they are also finding their way into other sectors. Think of construction projects, where they are used to transport building materials from location A to B, for example. The shipping container corner can be welded under a platform and serves as a connecting piece to clamp a heavy-duty swivel castor with ISO twist lock.
