Product Overview

This isS275JRH grade hot dip galvanized welded GI steel pipe, a carbon steel hollow section manufactured by ERW welding technology. The steel pipe undergoes professional hot-dip galvanizing treatment to form a uniform zinc coating on the surface, featuring excellent anti-corrosion and rust resistance. It covers a complete size range from 1/2 inch to 8 inches, with stable mechanical properties, smooth pipe surface and easy processing. It is a cost-effective structural and fluid conveying steel pipe widely exported for industrial and construction usage.
