Structural Advantages

Strength-to-Weight Ratio: RHS/SHS profiles provide higher load capacity compared to solid sections while reducing overall structural weight.
Uniform Wall Thickness: Our HFW process ensures minimal variance, essential for precision engineering and laser cutting.
Ready for Finishing: Smooth surfaces are optimized for immediate powder coating or galvanizing without extensive preparation.

High-quality RHS stock with precise corner radii.

Hollow Section FAQ

Q: What is the difference between Pre-Galvanized and Hot-Dip Galvanized (HDG)?

A: Pre-Galvanized is made from steel strips already coated with zinc, offering a smooth finish for indoor use. HDG involves dipping the finished pipe into molten zinc, providing a thicker coating (Z275+) for superior outdoor durability.

Q: Can you provide custom lengths or R-corner sizes?

A: Yes. We support precision cutting to specific project lengths and can adjust R-corner radii for large-volume orders according to mechanical requirements.
