Galvanized stainless steel coil description
What is Galvanized stainless steel coil ？
Galvanised steel is mild steel with a coating of zinc The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion
Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.
Galvanized stainless steel coil advantage
- 1、Corrosion and rust resistance: The main advantage of galvanised steel coil is its anti-corrosion and anti-rust properties. The iron element in steel is a highly reactive chemical, prone to rusting. but the addition of zinc plays a role of protective buffer between the steel and moisture or oxygen. So the zinc coating acts as a barrier to resist external attacks, and will sacrifice itself to protect the underlying steel.
- Life expectancy: With galvanization, the life expectancy of GI coil is far in excess of 50 years in working environments, and it can last over 20 years with severe water exposure.
- Cost: Firstly, galvanizing is a lower overall cost compared to other coatings. In addition, galvanized steel coil can be applied at any time when delivered. It does not require additional preparation for the surface, inspections, painting or coatings.
- 2、Durability and reliability: Galvanized steel often uses hot rolled or cold rolled steel coil as base metal. The strength of steel is high and the zinc coating is solid and enduring.
