Import Dn125 Galvanized Pipe — Buy in Bulk from Supplier in Viet Nam

DN125 galvanized pipe is a longitudinally welded steel tube with an outer diameter of 125mm, manufactured using high-frequency electric resistance welding. The wall thickness conforms to GB/T3091-2015 standards, with a nominal pressure rating suitable for low to medium pressure fluid conveyance. Surface treatment is hot-dip galvanized, providing a minimum zinc coating of 450g/m² as per ASTM A123, though exact coating weight must be confirmed with the supplier. This pipe is not intended for potable water systems in new installations, as many countries have phased out galvanized piping for internal plumbing due to corrosion and sediment buildup.

The base material is carbon steel, typically Q235B or SS400 grade, with tensile strength between 370-500MPa. The pipe is produced using ERW or HFW methods, resulting in a consistent seam with minimal distortion. While cold galvanizing is prohibited in most markets, hot-dip galvanizing remains acceptable for industrial applications such as fire suppression lines, electrical conduit, and highway guardrail supports. Typical tolerances for diameter are ±0.5mm and for wall thickness ±10%, which align with international standards for structural and mechanical piping.

This pipe is commonly purchased by contractors in construction, infrastructure, and industrial maintenance sectors, particularly in regions where copper or PVC alternatives are cost-prohibitive. Buyers often specify it for temporary installations, outdoor utility runs, or non-potable fluid systems. Trade terms offered include FOB, CFR, CIF, and EXW, with delivery times of 7 to 15 days after order confirmation. Packaging is typically bundled with steel straps and marked with product grade, size, and batch number. Buyers should verify coating adhesion and dimensional consistency before shipment.

Shandong Jintuo Metal Materials Co., Ltd is a trading company based in Liaocheng City, a major hub for steel tube distribution in China. The company sources products from certified mills and maintains inventory in regional warehouses, enabling faster turnaround for bulk orders. It does not manufacture pipes itself but acts as a supplier with verified export experience to markets in Southeast Asia, Africa, and Latin America. There is no public information indicating in-house testing facilities or production capacity.

The supplier has no recorded response rate or average response time, and no certifications such as ISO or BV are confirmed as held directly by the company. The listing states certifications are 'as per customer,' meaning they are obtained upon request rather than standard. The company's business model emphasizes flexibility in order size and delivery scheduling, particularly during peak construction seasons. No claims about years in operation, employee count, or client names are substantiated in the source data.
