In the construction industry where safety is non-negotiable, you need more than just steel pipes-you need reliable performance. As a leading Chinese manufacturer of ERW scaffolding pipes, we specialize in providing High-Frequency Welded (HFW) pipes strictly compliant with ASTM A53 Grade B. Our products are not only ISO 9001 certified but are also preferred for numerous overseas infrastructure projects due to superior galvanization and precise dimensional tolerances.
Key Specifications (US Standard Compliant)
We fully understand the strict specifications of the US market. Our scaffolding pipes feature a standard 48.3mm (1.5-inch NPS) outer diameter, perfectly compatible with universal US-style clamps and couplers.
| Parameter | Standard Value | Note |
|---|---|---|
| Standard | ASTM A53, ASTM A36, ASTM A139, EN10210, EN10219 | Compliant with ASTM standards |
| Outer Diameter | 48.3 mm (1.5" NPS) | Industry standard for scaffolding |
| Wall Thickness | 0.055''-0.14'' (1.65-3.5mm) | |
| Material Grade | GR.B, S235JRH, S275J2H, S355JOH | |
| Length | 6.0 m / Customized | Standard or cut-to-length available |
Unmatched Quality Advantages
█ Seam-Like High-Frequency Welding: Using advanced ERW technology, the weld seam strength is nearly identical to the base metal, eliminating the risk of seam splitting under heavy loads found in traditional scaffolding.
█ True Hot-Dip Galvanizing: We refuse "cold spray" or "electro-galvanizing". True HDG ensures both inner and outer walls are protected, offering a corrosion resistance lifespan of up to 20 years, perfect for the variable US weather conditions.
█ Strict End Protection: Pipe ends are protected by plastic dust caps to prevent damage to threads or cuts during shipping and handling.
Export Capacity & Logistics
Leveraging the industrial cluster advantages of major ports (Tianjin), we offer high production flexibility and export efficiency.
Capacity: Monthly output exceeds 5,000 tons, ensuring on-time delivery for large-scale projects.
Packing: Standard export hexagonal sea-worthy bundles.
Logistics: Extensive experience exporting to the US market; proficient in customs clearance documentation (CO, Fumigation certificate, etc.).
Stop worrying about project delays caused by low-quality pipes. Choose us for ASTM A53 compliance, genuine galvanized protection, and competitive Chinese factory pricing.
