Product Features
- Hot-rolled one-piece forming gives uniform thickness, flat surface, and good bending and welding performance.
- Complete material options provide stable toughness, tensile strength, and load-bearing capacity.
- Wide size range supports cutting, punching, and hot-dip galvanizing for corrosion protection.
- Flexible use as a standalone section or combined with angle and channel steel for structural assemblies.
