Detailed Description
Cold Roll forming hollow section is an economical lightweight thin-walled steel cross-section, also called cold-formed steel cold-formed profiles or profiles. Light steel cold-formed steel is the production of primary materials. It can be produced special thin sections and complex shapes and reasonable. Compared with hot-rolled steel in the same case of cross-sectional area, radius of gyration can be increased 50 to 60%, moment of inertia can be increased from 0.5 to 3.0 times, which can be a more reasonable use of the material strength; and ordinary steel ( that is, from the traditional I-beam, channel steel, angle steel and steel production) compared to savings of 30 to 50% of steel.
