Product Description
Hot Dipped Galvanized Serrated Outdoor Drain Cover High Strength for Building Steel Grating
Galvanized steel grating is an ideal product for wet, slippery situations where corrosion resistance is vital. The mild steel gratings undergo hot dip galvanizing in a galvanizing bath with a 7-tank surface cleaning process. The zinc used for hot dip galvanizing is 99.95% pure, and the galvanized coating complies with IS-3202/IS-4759/IS-2629/IS-2633/IS-6745, ASTM-A-123, or equivalent international standards.
