ASTM A53 BS1387 DIN2244 Round ERW Welded Steel Pipe 5.8M / 6M for Structural and Engineering Applications

1．Product Overview

ASTM A53, BS1387, and DIN2244 round welded steel pipes are used for construction structures, machinery fabrication, fencing systems, greenhouse frames, transportation components, furniture tubing, and general engineering applications.

The pipe is manufactured by ERW welding technology and can be supplied with galvanized, oiled, or black surface finish. Standard lengths include 5.8M and 6M, while customized lengths can be arranged according to project requirements.

2．Technical Solution

The steel strip is continuously formed into a round pipe shape and welded through the ERW process. This production method supports stable weld seam quality, consistent wall thickness, and reliable dimensional control.

Galvanized pipes are suitable for outdoor and humid environments. Oiled pipes provide temporary anti-rust protection during storage and

transportation. Black pipes are suitable for welding, painting, and further fabrication.
