Container Corner Post Roll Forming Machine
What Is a Container Corner Post Roll Forming Machine?
A container corner post roll forming machine produces the square and rectangular steel tube sections used as corner posts in shipping containers, container houses and modular buildings. Corner posts carry the stacking load of containers, so they are formed from high-strength steel (2.5-4.0 mm) into closed sections — either by roll forming and welding the seam or by roll forming open sections that the buyer closes. Container house builders in Africa, the Middle East and Southeast Asia increasingly produce their own corner posts locally.
Typical Sections
- Standard container corner posts: square/rectangular sections per ISO container dimensions.
- Modular house posts: lighter sections for container homes and offices.
- Options: inline seam welding for closed tubes, or open profiles for local welding.

Applications
Container manufacturers, container house producers and modular building companies produce corner posts for ISO containers, refrigerated containers, container offices, container homes and modular classrooms.
FAQ
Can the machine produce closed square tube sections?
Yes — with an inline high-frequency welding unit the roll-formed section is closed and welded continuously; without welding it produces open sections.
What thickness does it handle?
2.5-4.0 mm high-strength steel, depending on the container standard.
What sizes can be produced?
Sections per ISO container or modular house drawings; the machine is tooled to your profile.
Is this used for container houses too?
Yes — modular and container house builders use lighter corner sections from the same machine family.
What is the minimum order quantity?
MOQ is 1 set.
