This Standard specifies the range, classification, code, technical requirement, dimension, shape, weight, permissible deviation and marking of cold formed steel hollow sections for general structure. This Standard is applicable to cold forming cold rolled or hot-rolled tandem rolling steel plate and steel strip, and cold-rolled forming section manufactured in continuous cold-roll-forming machine group. For cold formed steel hollow section specified by this Standard, high frequency resistance welding is mainly adopted, and hydrogen arc welding or other welding methods may be adopted. This Standard is not applicable to cold-rolled forming section manufactured through drawing, stamping, folding and so on.

Summary
This Standard specifies the range of cold-formed structural hollow sections, classification, code, technical requirements, size, shape, weight, tolerance and markers. This Standard is applicable to the available cold deformation of cold-rolling or hot-rolled steel sheet and strip in a continuous roll production of cold-formed steel cold-formed unit. The standards required by major cold-formed hollow sections using high-frequency resistance welding, may also TIG welding or other methods. This standard does not apply to drawing, stamping, bending, etc. to produce cold-formed steel.
