Hot Dipped Galvanized Steel Grating Stair Tread Grid with ASTM A36 Q235 and Stainless Steel 304 Options
Steel Grating is welded from bearing steel bars and cross twisted bars according to required pitch spacing between steel bars using specialized welding machines. This grid building material offers exceptional strength and durability for various industrial applications.
All gratings are manufactured using high-quality standard steel materials that provide excellent hardness and high tensile strength. The product features:
- Extreme durability and load-bearing capacity
- Superior corrosion resistance
- Excellent anti-slip performance
- Customizable specifications based on application requirements
Available in a range of spacing pitch, thicknesses, and heights to meet specific load-bearing requirements for different installation environments.
