Coated sheet metal is a common name for electro-galvanized sheets or strips made of cold-rolled low-carbon steel, which are coated on both sides with commercial pure zinc or another metal (aluminum, silicon, magnesium). Galvanization means adding an outer surface layer to the sheet or other material using hydrolysis. The primary purpose of this process is to protect metals from corrosion.
Depending on the production method, galvanized sheet metal can be divided into:
> hot-dip galvanized sheet > electro-galvanized sheet.
Hot-dip galvanizing means that after pre-treatment, the coil is immersed in liquid metallic zinc to adhere a zinc protective layer to the steel surface, thereby improving the material’s corrosion resistance and enhancing its properties.
Electro-galvanizing (cold) consists of creating a smooth and dense metal coating on the plate through electrolysis.
Our suppliers – Italian service centers – slit and cut to length coated coils delivered from European steel mills into smaller coils, sheets, blanks, and strips in a wide range of formats. The technological development of the companies and careful selection of raw materials allow us to guarantee the excellent quality of the supplied products.
The application of zinc and magnesium alloy (+ZM) is also suitable for particularly aggressive environments, such as marine environments. Various appearance and surface treatment options are available for each product category.
Surface protection:
The surface of coated materials can also be without surface protection, but we do not offer such surfaces.
NOTICE: please state the requirement for the surface of coated materials with care – whether it is a surface MA C = M (minimized spangle) A (standard surface) C (passivated), or MC C = M (minimized spangle) C (high-quality surface) C (passivated), and others.
Hot-coated materials require dry storage conditions and a suitably controlled environment due to their sensitivity to oxidation between coil wraps or sheets. The materials can be easily surface-painted and are well-weldable; however, verification of these properties is the responsibility of the buyer, not the supplier.
Thickness of coated materials:

Electro-galvanized steels have mechanical properties similar to low-carbon steels for cold forming, which, thanks to their flexibility and ductility, are particularly suitable for cold forming.
Surface treatments for electrolytically coated materials:
The surface has a homogeneous finish with possible color deviations, without a specific roughness value.
USE FOR SPECIFIC APPLICATIONS WITH HIGH-QUALITY PAINT MUST BE SPECIFIED AT THE TIME OF ORDER.
Products can be supplied with various surface treatments such as oiling, passivation, phosphating, and their combinations. The most commonly used products include only passivation “C” – hot-dip galvanized materials, or passivation and phosphating “PC” – for electro-galvanized (+ZE). To ensure adequate product protection, delivery and storage must be indoors.
