Product Description

Q195 / Q215 / Q235 Round and Ellipse Welded Steel Pipes with Galvanized, Oil Coated, and Black Surface

1．Product Overview

Q195, Q215, Q235, SPHC, SPCC, 08Yu, and 08Al welded steel pipes are suitable for construction, industrial fabrication, machinery frames, furniture structures, agricultural systems, and general steel engineering applications.

The product is available in round and ellipse pipe profiles. Round pipes are commonly used for structural and engineering applications, while ellipse pipes are suitable for decorative frames, furniture, and shaped steel structures.

2．Technical Solution

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

Surface treatment options include galvanized, oil coated, and black finish. Galvanized pipes are suitable for outdoor and humid environments. Oil coated pipes provide temporary anti-rust protection during storage and transportation. Black pipes are suitable for welding, fabrication, and further painting.
