Product Profiles

Hot-dip galvanized steel grating combines carbon/alloy steel with a 50-150μm zinc coating, offering corrosion resistance for marine, chemical, or humid environments. Its welded/press-locked structure supports heavy loads (e.g., 10 tons/m²) with minimal deformation. The open-grid design reduces weight by 30%-40% vs solid plates, enhancing portability. Anti-slip serrated surfaces (friction coefficient ≥0.6) ensure safety in oily/wet areas. With 30%-70% open area, it enables airflow and 50%-90% light transmission, ideal for cooling towers. Prefabricated panels (e.g., 1m×6m) with bolt-fastening cut labor by 40%. The zinc layer lasts 20+ years (mild climates), requiring no maintenance, while 100% recyclability aligns with sustainability goals. Common in refineries, power plants, bridges, and drainage systems.
