Import Erw Welded Steel Pipe — Buy in Bulk from Supplier in China

ERW welded steel pipes from Taian Henson Metal Co., Ltd. are manufactured in hot-dip galvanized form, with outer diameters ranging from 20mm to 405mm and wall thicknesses between 1.2mm and 15.7mm. These pipes are produced using electric resistance welding, ensuring a continuous seam with uniform strength. The galvanized coating provides corrosion resistance suitable for outdoor and humid environments, commonly used in plumbing, structural framing, and irrigation systems.

The base material is typically low-carbon steel, though the exact grade is not specified. The hot-dip galvanizing process results in a zinc coating thickness that typically exceeds 50 microns on average, following ISO 1461 standards. The pipes are not internally coated, and no mention is made of chemical treatments or surface passivation. These characteristics align with standard galvanized ERW pipe production in China, where cost efficiency and export volume are prioritized.

These pipes are sourced by distributors in construction, agriculture, and light industrial sectors, particularly in regions with high humidity or corrosive soils. Buyers commonly order in quantities above 5 metric tons, though the supplier does not state a minimum. Packaging is described as secure, but no details are given on bundling or protective wrapping. Delivery is arranged under FOB or CIF terms, with payment via L/C or T/T. No certifications are verified, so buyers must request documentation independently.

Taian Henson Metal Co., Ltd. is registered in Taian, Shandong Province, China, and operates as a trading entity with no disclosed manufacturing facilities. The supplier is classified as harbor-tier, indicating export activity, but has a 0.00% response rate and no recorded response time, suggesting limited direct communication channels. No company history, employee count, or client references are provided in the listing.

The supplier does not claim certifications such as ISO or FSSAI, despite the source description mentioning them. These claims are unverified and cannot be confirmed. The company appears to act as an intermediary sourcing ERW pipes from regional mills. Buyers should treat this as a trading company and request all technical documentation directly before committing to an order.
