镀锌C型钢是指采用高强度钢板，经过冷弯，辊压成型，具有壁厚均匀、截面性能优良，强度高的新型钢材。镀锌C型钢广泛用于钢结构建筑的檩条、墙梁，亦可自行组合成轻量型屋架、托架等建筑构件，还可用于机械轻工制造中的柱、梁和臂等。抗震支吊架中，也以镀锌C型钢为主要材料。
Galvanized C-type steel refers to the new steel with high-strength steel plate, after cold bending, with uniform wall thickness, excellent section performance and high strength.Galvanized C-type steel is widely used for the purlin and wall beams of steel structure buildings, which can also be combined into lightweight building frames and brackets, and can also be used for columns, beams and arms in mechanical light industry manufacturing.In the seismic support hanger, galvanized C steel as the main material.
