We have been in this field for 13 years, with high quantity. We hope to cooperate with you !

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
