HDG Square Steel Pipe Building Material
The HDG Square Steel Pipe Building Material offered by Tianjin Ruijie Steel Pipe Co., Ltd. is a hot‑dipped galvanized carbon‑steel tube produced in square sections. It is supplied in grades Q195, Q215, Q235 and Q345 with a zinc coating applied by hot‑dip process. Standard outer dimensions range from 10 mm × 10 mm up to 600 mm × 600 mm, and wall thickness is available between 0.4 mm and 25 mm. Lengths are delivered between 5.8 m and 12 m, with a common commercial length of 6 m that can be cut to order. The pipe conforms to ASTM A53, API 5L, GB/T 3091 and other recognised standards such as DIN EN 10216‑1 and JIS G3466. Typical hot‑dip zinc coating thickness for this class of pipe is about 50 µm, providing long‑term corrosion resistance in outdoor structures. Dimensional tolerance of ±0.5 mm on wall thickness is standard for structural steel tubing, ensuring consistent load‑bearing capacity. Surface finish may be left galvanized or finished with a black oiling treatment for additional protection. Buyers in Southeast Asia, North America, Canada and Europe commonly use these pipes for building frames, bridges and utility conduits. The supplier ships the product in bundled pallets wrapped in protective film, but exact packaging details should be confirmed per order. Trade terms, minimum order quantities and payment conditions are not listed and must be negotiated directly with Tianjin Ruijie Steel Pipe Co., Ltd.

Sourcing HDG Square Steel Pipe Building Material from Tianjin Ruijie Steel Pipe Co., Ltd. - China Import Guide
Before placing an order, verify the exact steel grade, wall thickness and outer dimensions required for your project. Request the mill test report and any applicable certification copies to confirm compliance with ASTM, API or GB standards. Ensure that the supplier can provide the custom length or dimension you need, and clarify whether the surface finish will be galvanized only or include black oiling.
Discuss logistics early by asking the supplier about the preferred Incoterms, typical lead time and available payment methods. Since response data is not recorded, establish a clear communication channel to obtain a written quotation that includes freight options, loading port in Tianjin and any handling charges. Clarify whether the supplier can arrange container loading or prefers buyer‑managed freight forwarding.
Plan for quality inspection by arranging a third‑party surveyor to check dimensions, coating thickness and surface condition before shipment. Request a pre‑shipment inspection report and a Certificate of Conformity that references the relevant standards. Maintaining these documents will help streamline customs clearance and ensure that the received pipes meet the agreed technical specifications.
