常见问题
出口发货的最小起订量（MOQ）是多少？
我们的标准 MOQ 为每种规格 20 公吨，与单个 20 英尺集装箱装载量一致。订单总量达到 25 吨及以上时，可安排混装规格集装箱。
每次发货都会提供材质测试证书吗？
是的。每批货物都随附符合 EN 10204 Type 3.1 的工厂测试证书，涵盖化学成分、力学性能、锌层重量和静水压试验结果。
镀锌管出口的典型交货时间是多少？
现货商品在 7–10 个工作日内发货。定制订单——包括非标准直径或更厚锌层——通常从订单确认到装港需要 20–30 天。
你们能供应按定制长度切割或带螺纹端的钢管吗？
当然可以。我们提供 ±5 mm 公差的精密切割，以及 NPT 或 BSP 螺纹并带接箍端，所有这些均在镀锌前于厂内完成，或按项目图纸在预镀锌管上加工。

Acceptable Galvanized Pipe Quality with Initial Documentation Delay Resolved
Ordered 22 tons of hot-dip galvanized pipe, 101.6mm OD, 4.0mm wall, plain ends, Q235B, for a fencing and perimeter barrier project in Ontario. Pipe dimensions and zinc coating weight (280 g/m²) were within spec on arrival. The issue we encountered was a 3-day delay in receiving the full EN 10204 Type 3.1 documentation package after shipment departed—our customs broker needed the hydrostatic test data urgently and we had to follow up twice. The export team did resolve it and sent the complete certificate set via email within the same day once escalated. Pipe quality itself was acceptable for the application. Recommend confirming the complete documentation timeline upfront before shipment release for time-sensitive import clearances.

Perfect Galvanized Pipes for Southeast Asia Distribution Program
As a regional steel distributor, we placed a 120-ton order covering multiple sizes—21.3mm to 323.9mm OD, wall thicknesses from 2.0mm to 10.0mm—in both Q235B and Q345B grades for distribution across Southeast Asian markets. All batches carried EN 10204 Type 3.1 certificates with zinc coating weights ranging from 120 g/m² to 480 g/m² depending on grade, all matching order specifications exactly. SGS pre-shipment inspection passed first time across all 12 bundle configurations. Mixed-size container arrangement was handled efficiently by the export logistics team. CIF Singapore delivery completed in 14 days. This is our fourth procurement cycle with this supplier and product consistency across orders has been a key reason we continue to consolidate volume here.

Reliable ASTM A53 Galvanized Pipe for Industrial Conveyor Frames
We ordered a mixed container of ASTM A53 Grade B galvanized pipe—25 tons total, combining 2-inch and 3-inch nominal sizes at 6.0m lengths—for conveyor support frame fabrication at our Michigan facility. Mechanical properties on the MTCs were solid and matched our incoming inspection results. FOB Tianjin terms worked well for our freight forwarder. Stock items shipped in 9 business days as quoted. One minor point: two bundles had slightly loosened steel strapping on arrival, though no pipe damage occurred. Raised it with the export team and they confirmed reinforced strapping on future orders. Overall quality and pricing justify continued sourcing.

Premium Galvanized Conduit Pipes for Offshore Support Structures
Sourced 25 tons of heavy-duty hot-dip galvanized pipe, 88.9mm OD, 5.49mm wall, threaded and coupled BSP ends, for conduit and support frame applications on a marine platform facility in Western Australia. The 600 g/m² zinc coating specification was critical for saltwater environment compliance, and the Mill Test Certificates confirmed coating weight at 592 g/m² with full traceability. TÜV inspection was arranged without issue. Custom threading was done in-house prior to galvanizing as requested, and thread gauging certificates were included in the documentation package. Arrived at Fremantle in 24 days on a CIF basis. This was our second order; first order experience was what brought us back.

Good Value Galvanized Structural Pipe for Building Frames
Ordered 30 tons of Q235B galvanized pipe, 219.1mm OD, 6.0mm wall, beveled ends, for structural column applications in a commercial building project in São Paulo. Material quality and zinc coating (measured at 310 g/m²) met our project specifications. EN 10204 Type 3.1 certificates were complete and accepted by our structural engineer. Delivery took 32 days to Santos port, which was 4 days longer than the initial estimate due to port congestion at Shanghai—supplier communicated the delay proactively and updated the ETA in advance, which we appreciated. Pricing was competitive and the export packaging held up well during the ocean transit. Would order again with slightly earlier lead time buffer factored in.

Outstanding Hot-Dip Galvanized Pipes for Highway Guardrail Installation
Placed an order for 80 tons of ASTM A53 Grade B hot-dip galvanized pipe, 60.3mm OD, 3.91mm wall, plain ends, for highway guardrail and barrier systems across a road development project in Abu Dhabi. Zinc coating weight was certified at 550 g/m², critical given the harsh coastal environment here. Tensile strength test results showed 430 MPa, exceeding the ASTM A53 Gr. B minimum of 415 MPa. The CIF quotation came back within 20 hours of our inquiry with a full production timeline and packaging plan attached. Bureau Veritas inspection was arranged at our request with no delays. We compared pricing from four regional suppliers and this was 8% more competitive on a landed-cost basis.

Superior Q345B Galvanized Tubes for Greenhouse Structures
We sourced 60 tons of pre-galvanized Q345B square and round tubes, OD ranging from 48.3mm to 168.3mm, wall thickness 3.0mm–6.0mm, for a large-scale commercial greenhouse framework project in Bavaria. Yield strength test results came back at 368 MPa, well above the 345 MPa minimum. Zinc coating uniformity across the full 6-meter lengths was consistent—no bare spots identified during our incoming QC. Custom cutting to ±5 mm tolerance was performed accurately; we spot-checked 30 pieces and all were within tolerance. SGS pre-shipment inspection was coordinated efficiently by the export team. Delivery from Tianjin port to Hamburg took 28 days total, fitting our construction schedule precisely.

Excellent Galvanized Pipes for Municipal Water Project
Ordered 45 tons of hot-dip galvanized steel pipe, 114.3mm OD, 4.5mm wall thickness, BS 1387 Heavy class, for a municipal water supply expansion project in the Midlands. Zinc coating weight measured at 420 g/m² on arrival inspection—fully within spec. Mill Test Certificates (EN 10204 Type 3.1) covered chemical composition and hydrostatic test results, accepted by our client's engineer without any queries. Shipment arrived at Felixstowe port in 18 days from order confirmation, 2 days ahead of the CFR schedule. Packaging was solid—waterproof woven cloth with steel strapping, zero transit damage across the entire bundle. Third order with this supplier and quality has been consistent throughout.
