ISO Certificate Hot Dipped 25 x 25 Inch HSS Galvanized Steel Tube 16 Gauge
Product Specification
Hot-dip galvanized square tube is a square tube made by welding a steel plate or steel strip after crimping. On this basis, the square pipe is placed in the hot-dip galvanizing bath and then formed after a series of chemical reactions. While the amount of cold galvanization is only 10-50g/㎡, which has poor corrosion-resistance performance and is not suitable for extreme environments. Hot-dip galvanized square tube is superior to the cold galvanized square tube in appearance, strength, and mechanical behavior.
