Frequently asked questions
Hot-dip galvanized tubes are formed first, then immersed in molten zinc, resulting in a thicker, more durable coating (typically 200-600 g/m²). Pre-galvanized tubes use zinc-coated steel strip formed into the final shape, offering a smoother, thinner coating (30-150 g/m²) at lower cost. Hot-dip is preferred for outdoor/structural applications; pre-galvanized suits indoor or decorative uses where appearance matters.
Consider your environment: indoor/dry (30-80 g/m²), general outdoor (200-400 g/m²), coastal/industrial/heavy moisture (400-600+ g/m²). Thicker coatings cost more upfront but deliver longer service life and lower lifecycle costs. We can advise based on your specific application and location.
Yes. We provide MTC per EN 10204 3.1 or 3.2, including chemical composition, mechanical properties, and dimensional verification. Full material traceability is standard practice. This is the most requested document by international B2B buyers.
We use advanced galvanizing equipment with precise control of immersion time and temperature. Coating thickness is verified using magnetic induction gauges at multiple points on each pipe. We follow EN ISO 1461 and ASTM A123 testing protocols to ensure uniformity.
Yes. We offer cutting to any length below 16 meters, as well as punching, bending, and welding services. This reduces your on-site processing time and labor costs. Provide your drawings or specifications for a tailored quote.
Our standard MOQ is 5 tons for regular specifications, but we accommodate smaller trial orders for new customers. For special customizations, MOQ may vary.
Yes. We welcome SGS, BV, or other third-party inspections appointed by the buyer. We also provide pre-shipment inspection reports from our own CNAS-accredited laboratory at no extra cost.
We offer FOB, CFR, CIF, EXW, and FCA terms. Payment is typically by T/T (30% deposit, 70% against B/L copy) or L/C at sight. Delivery time is normally 15-45 days after receiving advance payment, depending on order quantity and specifications.
