Product Description

SPHC SPCC Rectangle and Ellipse Welded Steel Pipes with Oiled, Black, and Galvanized Surface

1．Product Overview

Rectangle and ellipse welded steel pipes are widely used for furniture frames, structural fabrication, machinery supports, steel framework, decorative tubing, and industrial applications.

SPHC and SPCC steel grades provide good forming performance and stable weldability for bending, punching, and fabrication processes. The pipes are available with galvanized, black, or oiled surface finish according to different application environments.

2．Technical Solution

The pipes are manufactured through ERW welding technology to achieve stable weld seam quality and dimensional consistency.

Galvanized surface treatment improves corrosion resistance for outdoor and humid environments. Oiled surface treatment provides temporary rust protection during transportation and storage. Black steel pipes are suitable for welding, machining, and painting applications.
