GB/T 6728-2002
AbolishedCold formed steel hollow sections for general structure--Dimensions，shapes，weight and permissible deviations
结构用冷弯空心型钢 尺寸、外形、重量及允许偏差
Application Summary AI generated
This standard specifies the dimensions, shapes, weights, and permissible deviations for cold-formed steel hollow sections used in general structural applications. It is applied in the manufacturing and quality inspection of square, rectangular, and circular hollow steel profiles for building structures, bridges, machinery frames, and other load-bearing steel constructions. Procurement and engineering teams use it to ensure consistency and interchangeability of structural steel components.
