Galvanized square steel tube
|Item||Galvanized square steel tube/ pipe|
|Introduction||Galvanized square steel pipes are steel pipes with equal sides. After the process is processed, it is rolled into strip steel. Generally, the strip steel is unpacked, flattened, crimped, and welded into a round tube, then the round tube is rolled into a square tube, and then cut to the required length.
1. The allowable deviation of the wall thickness of the galvanized square steel pipe shall not exceed plus or minus 10% of the nominal wall thickness when the wall thickness is less than 10mm, and plus or minus 10% when the wall thickness is greater than 10mm. Subtract 8% of the wall thickness. Except for the wall thickness in the joint area.
2. The usual delivery length of galvanized square steel pipe is 4000mm-12000mm, with 6000mm and 12000mm being the majority. Rectangular pipes are allowed to deliver short pipes and non-fixed-length products not less than 2000mm, and can also be delivered in the form of interface pipes, but the buyer should cut off the interface pipe when using it. The weight of short, non-fixed-length products shall not exceed 5% of the total delivery volume, and the square rectangular tube with a theoretical weight greater than 20kg/m shall not exceed 10% of the total delivery volume.
3. The curvature of the galvanized square steel pipe per meter is not more than 2mm, and the total curvature is not more than 0.2% of the total length.
