The coating thickness should correspond to the table given below and is line with industrial standards. Other than these, individual coating can be provided. As per best practices, a thinner zinc layer result in improved weld ability, better surface appearance and increased formability of the steel. The application of hot Dip Galvanized is so diversifed,

1. Construction feld: Like metal decks, Ceiling, Verandas, Shutters, Sheds, Culverts ducts, roofng, partitions, fences, steel frames, decorations.

2. Appliances: Freezers, DVD cases, motor cases, Water heaters, washing machines, Stores, air condition, microwave, refrigerators.

3. Transportation: Containers, under body panel, Bus and Truck body panel, Fuel tanks, aircraft, etc. 4. Agricultural equipments: Barns, Sheds, Silos, Feeders, water tanks, green houses.

5. Furniture and other applications: Vending machines, drums office equipment, steel furniture, waste bins, lighting.
