Overview
Powder Coated Steel Grating is produced from steel grating panels welded by load flat steel and twisted steel bars at defined intervals. After cutting, edging, grinding, and notching, the surface is powder-coated to provide corrosion resistance and color options including red, yellow, blue, white, and green. Powder Coated Steel Grating combines structural performance with customizable appearance.

Product Advantages
- Corrosion protection: Powder coating adds a protective layer, extending service life in mild corrosive environments.
- Color stability: Coating thickness typically 60–80 μm, providing uniform color and adhesion ≥ 2 MPa (pull-off test).
- Standardized load capacity: Based on flat steel height (20–30 mm) and thickness (3–5 mm), load tables per ISO 14122-3 available.
- Low maintenance: Smooth coated surface reduces dirt accumulation and cleaning frequency.
Applications
- Walkways and platforms in industrial plants
- Drainage covers and trench grates
- Architectural flooring (e.g., mezzanines, balconies)
- Stair treads and safety barriers
- Decorative exterior or interior grating
