ASTM A53 Hot Dipped Galvanized Steel Tube 

Product description Galvanized square tube is a hollow square section steel tube with a square cross-section shape and a size range of 20x20mm-500x500mm. The thickness of the galvanized layer is generally 20-30μm. Galvanized square tube has good corrosion resistance, rust resistance, and good surface quality, and is widely used in construction, machinery manufacturing, shipbuilding, railway construction, automotive industry, agricultural machinery, and other fields. Galvanized square tube is made by immersing the square tube in a zinc plating solution, which forms a protective layer on the surface of the square tube to prevent corrosion and rust. Galvanized square tube is easy to weld, cut, form, and machine, making it a popular choice for many applications. 304 Stainless U Steel Channels, Galvanized roll, Galvanized sheet, Hot Rolled Stainless Steel Sheets, Stainless Steel, Stainless Steel Pipe Item Stainless Steel Tube/Pipe…
