Q195 Q215 Q235 Round and Ellipse ERW 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 used for construction, industrial fabrication, machinery frames, furniture structures, agricultural systems, transportation components, and general steel engineering applications.

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

2．Technical Solution

The pipes are manufactured through ERW welding technology. Steel strip is formed into round or ellipse profile and welded continuously to provide stable weld seam quality and dimensional consistency.

Galvanized surface treatment improves corrosion resistance for outdoor and humid environments. Oil coated surface provides temporary anti-rust protection during storage and transportation. Black surface is suitable for welding, fabrication, machining, and further painting.

Different steel grades can be selected according to forming, welding, surface quality, and structural strength requirements.
