Product Description

08Yu 08Al Round and Square Welded Steel Pipes with Galvanized, Oiled, and Black Surface

1．Product Overview

08Yu and 08Al round and square welded steel pipes are widely used in steel structures, industrial fabrication, furniture frames, machinery supports, agricultural systems, and general engineering applications.

The product is manufactured from carbon steel grades including Q195, Q215, Q235, SPHC, SPCC, 08Yu, and 08Al. Round pipes are commonly used for structural and pipeline applications, while square pipes are suitable for framework, support structures, and fabrication projects.

2．Technical Solution

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

Surface treatments include galvanized, oiled, and black finish. Galvanized pipes provide improved corrosion resistance for outdoor and humid environments. Oiled pipes provide temporary anti-rust protection during transportation and storage. Black pipes are suitable for welding, painting, and further processing.
