08Yu 08Al Rectangle and Ellipse ERW Welded Steel Pipes with Galvanized Oiled and

08Yu 08Al Rectangle and Ellipse ERW Welded Steel Pipes with Galvanized Oiled and Black Surface

1．Product Overview

08Yu and 08Al rectangle and ellipse welded steel pipes are designed for structural fabrication, furniture frames, decorative tubing, machinery supports, agricultural structures, transportation components, and general engineering applications.

Rectangle pipes are commonly used for frame structures, support members, and load-bearing fabrication. Ellipse pipes are often selected for visible structures, furniture components, decorative frames, and shaped metal parts where appearance and profile design are important.

2．Technical Solution

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

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

08Yu, 08Al, and SPCC grades can be selected when the project requires better forming and fabrication performance.
