Overview
Cold Formed Structural Steel Profile combines low-carbon carbon steel with the dimensional precision of cold forming for reliable mechanical performance and consistent dimensional control. The cold formed sections deliver tight tolerances, high strength-to-weight ratio and efficient material use, making the profile suited to light steel framing, building structures, industrial racks, purlins and modern construction systems. Supplied to ASTM A36 / EN 10025-2 with mill test certification per EN 10204 3.1, it supports global procurement for efficient and lightweight building projects.

FAQ
Most enquiries reduce to a small set of recurring technical questions.
01 What is cold-formed structural steel profile?
Cold-formed profiles are made by roll-forming or press-braking thin gauge steel strip into C, Z, U, hat and other open sections at room temperature.
02 What are typical applications?
Cold-formed profiles are widely used for secondary structural members: purlins, girts, wall studs, floor joists, roofing, cladding supports and light framing.
03 What is the typical thickness range?
Cold-formed profiles are typically 1.0 - 6.0 mm thick. Thicker gauges up to 12 mm can be produced on request.
04 What standards cover cold-formed sections?
EN 10162 covers technical delivery conditions for cold-formed sections. AISI / AISC standards also apply for North American projects.
05 What is the difference between cold-formed and hot-rolled profiles?
Cold-formed profiles are produced from thin strip at room temperature for lighter members. Hot-rolled profiles are produced at elevated temperature for primary heavy structural members.
