Galvanized Sheet Metal

Galvannealed sheet is a steel product obtained by converting the zinc coating on steel into an iron–zinc alloy through a controlled heat treatment after hot-dip galvanizing, offering superior paint adhesion properties. Thanks to its matte and homogeneous surface structure, it is especially preferred in painted applications.

Combining the corrosion resistance of galvanized sheet with excellent paintability, galvannealed sheet provides a high-performance coating solution in automotive and industrial production.

What is Galvannealed Sheet?

Galvannealed sheet is produced by annealing the sheet at a specific temperature after hot-dip galvanizing. As a result of this process, zinc reacts with the steel surface to form an iron–zinc alloy. This gives the surface a rougher, matte structure that is highly suitable for paint adhesion.

This special alloy layer makes galvannealed sheet more suitable for painted production compared to conventional galvanized sheet.

Galvannealed Sheet Technical Specifications

• Iron–zinc alloy coating structure

• High paint adhesion performance

• Homogeneous and matte surface quality

• Good formability

• Suitable structure for welding and cutting processes

• Better paintability compared to galvanized sheet

Galvannealed sheet provides high efficiency in production processes where surface treatments are critical.

Galvannealed Sheet Applications

Galvannealed sheet is widely used especially in sectors requiring painted and aesthetic applications:

• Automotive body and chassis parts

• Painted sheet applications

• White goods and metal coating products

• Industrial panels and enclosure systems

• Electrical household appliances

• Precision sheet forming applications

Galvannealed Sheet Quality and Standards

Galvannealed sheet products are manufactured in accordance with the EN 10346 standard. Within this standard, there are quality grades such as DX51D+ZF, DX52D+ZF.

The coating type (ZF100, ZF140, etc.) should be determined based on the application area and corrosion resistance requirements.

Advantages of Galvannealed Sheet

• Superior paint adhesion performance

• Homogeneous and aesthetic surface appearance

• Good corrosion resistance

• Structure suitable for mass production

• Ideal solution for automotive and white goods industries

These advantages make galvannealed sheet an indispensable material in painted and coated products.
