Zinc Coating Steel Bar Grating Low Carbon Walkway Floor Drain Grate For Building Material

Low Carbon Walkway, Floor Drain Grate for Building Material
 
Steel Grating is made by welding with flat steel and bars with certain distances. It goes through cutting, opening, edging and other processes. The products enjoy the feature of high strength, light structure, high bearing, convenience for loading and other propertier. The hot dipped zinc coating gives the product excellent anti-corrosion. here is the advantage of steel structure:
