Metallic Coated

Galvanised steel is a process of applying a protective layer of Zinc to steel to prevent rust and corrosion. There’s a wide range of metallic coated products available to meet the requirements of different sectors.

Hot dipped galvanising is the most common method in which a Zinc coating is applied in a hot dip process using a bath of molten zinc. This method offers very good corrosion resistance with good forming properties.

Hot dipped galvanised has a strong thick coating and is known to have a very long life expectancy of between 20 to 50 years suitable for outdoor applications particularly in the building industry to ensure durability and longevity.

Electrogalvanised steel is a process where a thin layer of zinc is applied using an electrochemical procedure where the steel strip passes through several electrolytic cells successively. A current of electricity is passed through the electrolyte solution to cause the zinc to be deposited on the metal surface. The result is a uniform, thin, and smooth layer.

It is generally available with a thinner coating and a life expectancy less than hot dipped galvanised and therefore not suitable for outdoor applications.

However, Electrogalvanisation produces an excellent uniform smooth finish with good workability, weldability and is used in typical applications such as home appliances, metal furniture and automotive parts.
