1. Base material composition.

Commonly used structural steels are Q235B and Q355B, which are low-carbon steel with moderate strength and good toughness. They possess excellent weldability, meeting the requirements for building and structural load-bearing capacity.

2. Forming Process

The steel belt is formed using cold bending technology combined with high-frequency seam welding. The welds are dense, with high dimensional accuracy, uniform cross-sections, and excellent overall straightness.

3. Preservation processes.

The steel pipes undergo a comprehensive hot-dip galvanizing process, where they are immersed in high-temperature zinc liquid to form a metallurgically bonded zinc layer. The zinc layer is uniform and has strong adhesion, and its corrosion-resistant properties far surpass those of electroplated zinc and paint.
