Product  Description

Category Introduction

Weathering steel plates (anti-corrosion steel plates) add Cu/Cr/Ni/Sb and other alloy elements, forming a dense protective oxide film on the surface in the atmosphere, with excellent atmospheric corrosion resistance (no need for painting). Support coastal/industrial/acidic atmosphere scenarios, adopt hot rolling and corrosion optimization treatment, suitable for outdoor steel structure, landscape architecture, railway and chemical equipment.
