The SHS Galvanized Steel Hollow Section Tube Pipe is a square‑section structural steel tube that has been hot‑dip galvanised for corrosion protection. It is manufactured from carbon steel grades Q235, ST37 and conforms to ASTM A53 Grade B and equivalent standards. Available outer dimensions run from 20 mm up to 400 mm with wall thicknesses between 1.5 mm and 16 mm. Lengths can be supplied in 1 m, 4 m, 6 m, 8 m or 12 m as required by the buyer.
The galvanised coating typically provides a zinc layer of 50 - 100 µm, giving long‑term resistance in outdoor and industrial environments. Typical mechanical properties for the Q235 base steel are a tensile strength of 400 - 500 MPa and a yield strength around 250 MPa. The tubes are offered with optional surface finishes such as black paint or oil coating, and are marked according to buyer specifications. Export packaging consists of steel straps and a rust‑preventive coating applied before freight loading.
These tubes are commonly used for structural frames, scaffolding, fencing and automotive sub‑assemblies. Permanent Steel Manufacturing Co., Ltd. ships the product in bundled packs and can arrange payment on 20 % TT + 80 % TT, 100 % LC after sight (30 - 180 days) or other open terms. Buyers should verify the required dimensions, coating thickness and certification documents before finalising the order.

Before placing an order, buyers should obtain the product data sheet that lists the exact outer dimension, wall thickness, length and coating thickness. Request the mill test certificate and, if required, a coating thickness report to confirm compliance with ASTM A53 and the galvanising specification. Verify that the supplier can produce the requested marking and end‑treatment.
The supplier typically ships the tubes on a FOB or CIF basis; however the specific Incoterm should be agreed in the contract. Lead times depend on the size and quantity but are usually quoted after the order is confirmed; purchasers should ask for an estimated delivery schedule. Payment can be arranged via TT, LC or open terms, and the exact conditions must be confirmed with the supplier’s finance department.
Third‑party inspection before loading is recommended; common checks include dimensional inspection, coating thickness measurement and hydrostatic pressure testing. The supplier’s on‑site laboratories are capable of ultrasonic and radiographic examinations, and the results can be provided as part of the inspection report. Ensure that all required certificates - API, ISO, CE and EN 10204 - are included in the shipping documents.
