Galvanised Steel Square Tube

Main Products

Galvanised Steel Square Tube

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.
