What is Galvanized Steel?

There are two typical galvanizing ways to obtain a zinc coating: hot dip galvanizing and electrogalvanizing. Hot dip galvanizing is the process that steel is immersed into molten zinc bath to get a zinc coating surface. This not only helps protect steel from rust and corrosion, but also gives the steel a shiny attractive appearance. Electrogalvanizing is the process that uses electrolysis to coat the steel with zinc, which is neither cost-effective nor environmentally friendly. It is hardly to find electrogalvanized steel in our lives nowadays.

What are advantages of galvanized steel?

Because of permanently and successive zinc/iron alloy layers, galvanized steel offers many benefits than traditional steels. 

>>Corrosion Resistance: the zinc coating surface protects the base steel not only by providing barrier to corrosion elements, but also by the sacrificial nature of the coating. Galvanized steel often remains in working order with little maintenance for 40 years or more.

>>Excellent Surface Appearance

>>Formability: it can be simply bend to parts with deep drawing requirements.

>>Paintability: it can be painted with different colors.

>>Weldability: it is accepted various welding practices.

What are disadvantages of galvanized steel?

In spite of many benefits, galvanized steel is not always an ideal choice. Galvanized steel cannot be used underground without properly covered, which can be inconvenient for many jobs.

Where do we use galvanized steel?


It is primarily used in the construction industry, such as roofing, wall cladding, and support beams. It is also used in the automotive industry, due to its enhanced paintability, weldability and corrosion resistance. Moreover, it is an essential material for white goods application, such as refrigerators, air-conditioners, washers, microwaves, vending machines and audio visual systems.



Surface types ranging from standard A surface to high-end C surface properties

Adjustment of defined strip roughness possible

Post-treatment to protect against the formation of white rust: wide variety of oils, chromium-free passivation, anti-finger-print system or micro-phosphating



Application: Galvanized steel is generally used in Roofing, Ducting, Major Appliances, Cladding & Sliding, Water Heaters, Building Components and Accessories, Automotive Parts, Industrial Packaging, Electrical Boxes, Garage Doors, Ceiling Grid Systems, Light Steel Framing etc.
