Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent premature rust and corrosion. Proponents of galvanized steel, who may use it to construct or repair steel structures, for example, benefit from lower maintenance and repair costs because of its special properties. 

Galvanization provides corrosion protection, durability under harsh conditions, a long lifespan, versatility, availability, and sustainability. Without protection, steel will rust due to atmospheric conditions over time. The degree of rust will depend on the environment that the product is in. Rust is an iron oxide (typically a red oxide) which is formed by the reduction and oxidation reaction of iron and oxygen, in the presence of water or air moisture.

How Can We Achieve Galvanized Sheet Metal

Hot-Dip Galvanizing

This is the most popular sheet metal technique for galvanization. The process submerges metal parts in a bath of molten zinc to protect the metal and occurs in three different ways: 

The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.

It acts as a sacrificial anode, which is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal from corrosion. This means that if the coating is scratched, the exposed steel or iron will be protected by the remaining zinc.

The zinc protects its base metal by corroding before iron. 

The product can be used in various applications such as construction materials, pipe, electronics, furniture, materials with molten zinc to the hot rolled or cold rolled steel products.

Product	Coating Layer Structure	Characteristics	Appearance
GI(H)		A hot rolled steel plate is used as a base metal for this product. While molten zinc solidifies on the surface of the steel sheet, normal zinc crystallization is suppressed creating fine crystals.
GI		A cold rolled steel plate is used as a base metal for this product. While molten zinc solidifies on the surface of the steel sheet, normal zinc crystallization is suppressed creating fine crystals. The surface is flat and has a fine appearance after painting. Paintability is superior to ordinary products.
GA		Through a thermal diffusion process, a steel sheet and zinc react to produce an alloy layer. The weldability and the paintability are superior to traditional galvanized steel sheets. Fe in the alloy coating enhances corrosion resistance.

GALVANIZED STEEL SHEET: IS IT RESISTANT TO CORROSION?

The durability of galvanized steel and its resistance to corrosion and stains makes it a go-to material for many steel artworks. 

Galvanized steel is essentially steel that's been galvanized to protect it from corrosion and the elements. Virtually any experienced steel supplier will tell you that galvanization is one of the most effective tactics to protect steel from corrosion! 

Sheet Metals Online is committed to providing customers with galvanized steel that meets the highest possible quality requirements. It has a protective layer that prevents rust and corrosion, making it appropriate for various applications owing to its versatility.
