Hot dipped galvanized tubes are steel tubes that have been coated in a layer of zinc by a process called hot dip galvanization. The zinc coating provides a layer of protection to the steel tube, making it more resistant to corrosion and rust. This makes hot dipped galvanized tubes a popular choice for outdoor or industrial applications where the tubes will be exposed to harsh environments.
They are also often used in construction, fencing, and as steel pipe for transportation of fluids.
The process of hot dip galvanization involves cleaning the steel tube, immersing it in a bath of molten zinc, and then allowing it to cool and solidify. This results in a durable and long-lasting coating that protects the steel tube from the elements.
