Key Performance Advantages

High-Density Zinc Protection: Unlike standard commercial pipes, our hot-dipped process maintains an average zinc coating of 280g/m². This provides a thicker, more durable sacrificial layer, ensuring the pipes withstand harsh outdoor environments and corrosive fluid transport for years.
In-Line Burr Removal (Plain Ends): We focus on the details that define quality. Every BS1387 pipe is processed through our in-line clean-end machines to remove internal and external burrs. This prevents turbulence in fluid systems and ensures safe handling for workers during site assembly.
Specialized Scaffolding Excellence: We are experts in the production of 48.3mm OD scaffolding tubes (3.2mm/4.0mm thickness). Compliant with EN39 and BS1139, these tubes are optimized for temporary structures, formwork, and shoring systems, featuring a zinc coating above 210g/m² for enhanced service life.
Verified Fluid Safety: All pipes intended for plumbing or fluid transport undergo 100% hydrostatic testing. This rigorous quality control ensures that our BS1387 tubes meet the pressure requirements of modern building and industrial infrastructures.

Product Applications

Fluid Transportation: Low-pressure delivery of water, gas, and air in commercial and residential piping.
Scaffolding & Shoring: High-strength main components for construction scaffolding systems (48.3mm OD).
Fire Protection: Reliable grooved or threaded pipes for fire sprinkler systems.
Industrial Infrastructure: Structural frameworks, mechanical engineering components, and protective conduits.

Packaging & Delivery

Packaging: Seaworthy bundles secured with steel strips. Optional damp-proof wrapping is available to protect the galvanized surface from white rust during maritime transport.
Shipping Port: Efficient dispatch via Xingang Port, Tianjin, China.
Lead Time: Normally 18-20 days after confirmation of T/T, L/C, or D/P payments.
Delivery Methods: Support for both Container and Bulk carrier shipping to reduce freight costs.

Frequently Asked Questions (FAQ)

Q: Do your BS1387 pipes support threading according to BS 21?
A: Yes. We can provide high-precision threading and coupling (socketed) services that comply with BS 21 requirements for leak-proof connections.

A: In standard outdoor environments, our high-zinc coating provides significantly better corrosion resistance than pre-galvanized pipes, typically offering a maintenance-free life span of many years.

A: Absolutely. We have 15+ years of experience in scaffolding tube production, meeting EN39, EN10219, and BS1139 standards strictly.

A: Yes. We have a professional QC team and fully support third-party inspections to verify material grade, wall thickness, and zinc coating thickness.

A: Our MOQ is one full 20ft container. Mixed sizes and grades within one container are acceptable to optimize your logistics.
