Steel Tube that is covered with a layer of zinc metal is known as Galvanised steel. During the process of galvanizing, steel is immersed in a molten zinc bath, to ensure a tough and uniform barrier. These Galvanised steel pipes and tubes are used in water supply, Underground piping, Power, Refineries, Scaffolding, Steel Structures, Fire-fighting system, HVA, structural applications, etc. To seek long-term structural performance in the harshest of weather conditions, designers, builders, and consumers have turned to use zinc-coated steel pipes. This is because zinc-coated galvanized steel pipes and tubes resist the attack of wind, water, and road salts. Apart from being easy on the pocket GI pipes are highly corrosion-resistant, light in weight, easy to handle during transport and easy to join.
