Structure & Steel

Corner Castings

Heavy-duty steel fittings welded to the top and bottom of each corner post. These standardized blocks have oval openings that accept twist-locks, crane spreaders, and tie-down hardware for lifting and securing containers.

Role in Container Integrity

Every component of a shipping container’s steel structure contributes to its overall strength and durability. The corner castings plays a specific role in maintaining the structural load path — the route that forces travel through the container frame to reach the foundation.

Modification Considerations

When converting a container into a building, any changes to structural steel must be carefully planned. Cutting, welding, or removing material from load-bearing components requires compensating reinforcement designed by a qualified structural engineer. Ignoring this step can compromise the container’s ability to support roof loads, wind forces, or stacked weight.

Maintenance and Longevity

Steel components are vulnerable to corrosion, especially at welds, cut edges, and areas where the original paint has been damaged. Regular inspection and prompt treatment of surface rust will extend the service life of the container by decades.
