Product Description

Ellipse Circle Square Rectangle Galvanized Coated Black ERW Welded Steel Pipes for Structural and Industrial Applications

1．Product Overview

ERW welded steel pipes are widely used in construction structures, industrial fabrication, transportation systems, agricultural equipment, fencing, machinery manufacturing, and general engineering applications.

The product range includes ellipse, circle, square, and rectangle pipes with galvanized, oiled, or black surface finishes. Stable dimensional accuracy and reliable weld seams support both structural and conveying applications.

2．Technical Solution

The pipes are manufactured using electric resistance welding (ERW) technology to ensure stable seam quality, uniform wall thickness, and smooth internal surfaces.

Galvanized coating improves corrosion resistance for outdoor environments, while black and oiled surfaces are suitable for fabrication, painting, welding, and industrial processing.
