Q195 Q215 Q235 Round and Ellipse ERW Welded Steel Pipes for Structural and Industrial Applications

1．Product Overview

Q195, Q215, and Q235 round and ellipse ERW welded steel pipes are used for structural fabrication, industrial processing, furniture manufacturing, steel framework systems, agricultural structures, transportation components, and light engineering applications.

Round pipes are commonly selected for construction supports, handrails, fencing systems, and general pipe structures. Ellipse pipes are suitable for furniture frames, decorative tubing, visible metal structures, and architectural components where profile appearance is important.

2．Technical Solution

The pipes are manufactured by ERW welding technology. Steel strip is formed into round or ellipse pipe profile and welded continuously to provide stable seam quality, consistent wall thickness, and reliable dimensional control.

Q195 and Q215 are suitable for light forming and general fabrication. Q235 is commonly selected for structural applications requiring higher load performance. SPHC, SPCC, 08Yu, and 08Al can be selected when forming, bending, surface quality, or fabrication performance is required.

The product supports downstream cutting, bending, punching, welding, polishing, coating, and assembly processing.
