Galavanized sheet is quite useful in our daily life. These are the examples of galavanized sheet.

Electronics: Computer casings and precision instruments are made with zinc coating because it’s moisture- and rust-resistant.

Nails, nuts, and bolts: Unfortunately, the hot-dip coating process provides too much fill in the threads of nuts and bolts that are ⅜-inches or smaller, which can reduce the strength. Instead, electro-galvanizing (which involves electroplating, a process where a current of electricity is run through a saline/zinc solution with a zinc anode and steel conductor) and stainless steel are used. These electro-galvanized nuts and bolts go into light mechanical products, like cars and bicycles.

Piping: Galvanized piping replaced cast iron and lead in cold-water plumbing in the early 20th century. The life expectancy of galvanized plumbing is about 70 years, depending on the region’s impurities in the water supply, proximity to electrical grids, thickness of zinc, and whether the piping was coated on the inside and outside.

To increase the longevity, some galvanized piping were lined with epoxy resin, which is a petroleum-derived material known for its excellent adhesion, chemical and heat resistance, and insulation properties.
