Galvanized Square Tube
Use this page to prepare an RFQ for structural frames, fence systems, solar supports, and light steel fabrication using zinc coated square tube. It keeps the inquiry focused on grade, size, quantity, tolerance, certificate, packing, and destination details.
How To Specify This Requirement
Galvanized Square Tube RFQs should confirm the application, standard, grade, product form, size range, delivery condition, and inspection scope. Use the full project specification when tolerance, coating, testing, or certificate wording matters.
Himount Steel reviews the ordered standard, grade, dimensions, inspection level, packing method, and shipment route before confirming price and lead time. Final supply follows the buyer specification and accepted mill test certificate.

International Standard Notes
This page uses the buyer-facing reference `ASTM A500 / EN 10219 / project standard` and grade/code `Galvanized square tube, grade and zinc coating as specified` as RFQ checkpoints. The table below helps compare common international wording without claiming automatic equivalence.
| EN reference | EN 10346 is common for galvanized and metallic-coated flat products such as DX51D+Z and coating classes like Z275. |
|---|---|
| ASTM / JIS reference | ASTM A653 is common for galvanized sheet, ASTM A792 for Al-Zn coated sheet, ASTM A755 for prepainted sheet, and JIS G3302 / G3312 may be requested in Asian projects. |
| Order check | For Z275, G90, AZ150, SGCC, DX51D, PPGI, and PPGL orders, confirm substrate, coating mass, paint system, surface finish, RAL color, and packing requirement before quotation. |
