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.

3．Specifications

4．Application

This product is suitable for construction structures, handrails, supports, machinery frames, welded components, greenhouse frames, fencing systems, support tubes, vehicle components, trailer parts, tubular furniture, and general steel fabrication.

Round ERW welded steel pipe is commonly selected when the project requires stable pipe geometry, weld seam consistency, and flexible surface treatment options.

5．Processing

The round welded steel pipes support cutting, welding, bending, punching, drilling, galvanizing, painting, and secondary fabrication.

Customized pipe length, surface finish, and packing method can be supplied according to customer drawings or project requirements.
