Available Surface Treatments
Black Bare Steel
Features a smooth original mill surface without additional coating. Ideal for general structural use, this bare steel allows easy cutting, welding and repainting for secondary fabrication.
Anti-Rust Oiled Finish
A thin, consistent anti-rust oil film is applied on the steel surface. It effectively resists oxidation and surface rust during long storage and international shipping, keeping products in prime condition before arrival.
Red Oxide Primer Coating
Acts as a cost-effective fundamental anti-corrosion layer. With excellent surface adhesion, the red primer works perfectly as a base coat, supporting further topcoat finishing and advanced protective coating systems.
Hot-Dip Galvanized Coating
We provide tailored coating solutions for specific project demands. Coating thickness, colors and protective formulas can be customized based on actual
