Hot-Dipped Galvanized Water Pipe & Scaffolding Tube

Our hot-dipped galvanized water pipes are manufactured to provide exceptional durability and corrosion resistance for fluid transportation and structural construction. Fully compliant with international standards such as BS1387:1985, EN10255, and ASTM A53, our pipes feature a high-density zinc coating (average 280g/m²) to ensure a long service life in harsh environments. As a professional manufacturer with 15+ years of experience, we provide precision-engineered pipes that are 100% hydro-tested and finished with burr-free plain ends for maximum safety and performance.

Key Performance Advantages

Superior Anti-Corrosion Zinc Layer: Our pipes undergo a high-temperature hot-dipped galvanizing process, resulting in a robust zinc coating with an average weight of 280g/m² (approx. 40um). This provides a long-term barrier against rust and corrosion, extending the product life for both water delivery and outdoor structural use.
Burr-Free Plain Ends (Precision Finishing): Every pipe is processed through our specialized in-line clean ends machines. We focus on the critical detail of removing all internal and external burrs. This ensures a smooth flow for fluid transportation and prevents injuries during the assembly of scaffolding systems.
Dual-Purpose Functionality:
·Fluid Transport: 100% hydrostatic testing ensures zero leaks for water and gas delivery.
·Scaffolding Applications: We specialize in 48.3mm OD scaffolding tubes (3.2mm/4.0mm thickness) compliant with EN39 and BS1139, designed for high-strength temporary structures and shoring systems.
Reliable Quality Control: With over 15 years of manufacturing expertise, we control the quality from raw material (Q235/Q345) to the final galvanized surface, supporting third-party inspections (SGS/BV).

Product Applications

Water & Fluid Delivery: Low-pressure liquid transportation in residential and industrial plumbing.
Scaffolding Systems: Main components for construction frameworks, maintenance towers, and shoring.
Greenhouse Structures: Durable frames for agricultural greenhouses requiring high rust resistance.
Fire Sprinkler Systems: Reliable grooved or threaded pipes for fire protection networks.

Packaging & Delivery

Package: Seaworthy bundles secured with steel strips. Optional damp-proof packaging is available to ensure the zinc coating remains pristine during long-distance sea freight.
Lead Time: Normally 18-20 days after confirmation of T/T, L/C, or D/P payments.
Shipping Port: Efficiently loaded from Xingang Port, Tianjin, China, utilizing both Containers and Bulk Carriers.

Frequently Asked Questions (FAQ)

Q: What is the typical life span of your hot-dipped galvanized pipes?
A: Due to our high zinc coating weight (avg. 280g/m²), our pipes are designed for long-term corrosion resistance, lasting many years even in humid or outdoor construction environments.

A: Yes, we produce 48.3mm scaffolding tubes strictly according to EN39, EN10219, and BS1139 standards, with material grades like S235 and S355.

A: Removing burrs prevents turbulence and sediment buildup in water systems, and ensures that threaded or grooved couplings fit perfectly without damaging the seal.

A: We provide a standard average of 40um (280g/m²), but can accommodate requirements up to 70um for specific high-corrosion engineering projects.

A: Our minimum order quantity is one full 20ft container, and mixed sizes/specifications are acceptable to optimize your shipping costs.
