BS1139 Galvanized Scaffolding Tube (48.3mm Scaffold Pipe)
The BS1139 Galvanized Scaffolding Tube is a premium-grade, high-strength construction component engineered to provide unyielding support for scaffolding systems, shoring, and heavy-duty formwork. Manufactured in strict compliance with BS1139, EN 39, and EN10219 standards, this carbon steel tube serves as the primary load-bearing backbone for temporary high-rise access platforms.
Produced in our ISO9001-certified facility in Tianjin, China, using advanced ERW (Electric Resistance Welding) techniques, our scaffold tubes are available in high-grade materials such as S235, S355, Q235, and Q345. Featuring a robust hot-dipped galvanized surface with a zinc coating exceeding 210g/m², these tubes offer exceptional, long-term corrosion resistance in the harshest outdoor construction environments.

Frequently Asked Questions (FAQ)
Q: What makes the BS1139 standard different from standard commercial pipes?
A: BS1139 is a strict British Standard specifically dedicated to metal scaffolding. It mandates precise chemical compositions, exact dimensional tolerances (48.3mm OD), and specific mechanical performance—such as the 420 N/mm² tensile strength—to guarantee worker safety at extreme heights.
Q: Do you offer both 3.2mm and 4.0mm thicknesses?
A: Yes. We manufacture both the standard 4.0mm thickness typically used in heavy-duty scaffolding, as well as the 3.2mm thickness often preferred for lighter, high-tensile scaffolding systems compliant with modern EN39 standards.
Q: Can you verify the zinc coating weight of >210g/m²?
A: Absolutely. Our QC department rigorously tests the galvanization thickness for every batch. We also fully support SGS, BV, and other 3rd party inspections to independently certify the zinc coating weight before shipment.
Q: Are these tubes manufactured using seamless or welded techniques?
A: These scaffolding tubes are manufactured using high-frequency ERW (Electric Resistance Welding). This method provides a highly consistent and extremely strong weld seam that fully meets the demanding structural requirements of BS1139 and EN39.
