Metal powder coating-smooth surface powder coating

Powder coating for metal

Powder coating, also known as powder painting, is a coating technique that does not require solvents and is therefore particularly environmentally friendly. A fine powder is applied to metal surfaces by means of electrostatic charging and cured at high temperatures. The result is an even, durable and resistant protective coating.

Advantages of powder coating metal surfaces

Powder coating offers various advantages for different types of metal:

Corrosion protection

Powder coatings reliably protect metal surfaces against corrosion and the effects of weathering.

Aesthetic flexibility

A wide range of colours and many surface effects offer numerous design options.

High resistance

Powder coatings are resistant to abrasion, chemicals and mechanical influences.

Environmental protection

The process does not use solvents and enables virtually waste-free production. Excess powder can simply be reused, which contributes to sustainability.

Possible applications for powder coating

Building industry

Ideal for façade elements, window frames and balconies that need to be robust and colourfast

Mechanical engineering

For machine parts that withstand heavy mechanical loads

Automotive industry

Use on body parts, wheel rims and functional components

Furniture industry

Furniture parts, especially for outdoor use, benefit from the durable and scratch-resistant surface

Various metals for powder coating

Powder coatings are suitable for metals, including aluminium, stainless steel and steel. Each of these materials requires specific approaches that optimise the properties and end use of the component.

Metal	Corrosion protection	Mechanical resistance	Main application
Aluminium	high	medium	Construction industry, automotive industry, furniture industry
Stainless steel	very high	high	Architecture, food industry, mechanical engineering
Steel	high	very high	Construction, mechanical engineering, automotive engineering, furniture industry
Zinc	medium	high	Mechanical engineering, electronics, automotive engineering
Copper	medium	medium	Electronics, interior design, sanitary facilities

The surface quality of the different types of metal is improved by powder coating, depending on the intended requirement. Be it for increased corrosion resistance, better abrasion resistance or visual refinement.

Powder coating requirements for various metals

Aluminium

Aluminium is light and flexible, but susceptible to a wide range of environmental influences. The powder coating reinforces the surface and protects it from corrosion, scratches and weathering.

Stainless steel

Stainless steel is known for its natural corrosion resistance. However, in particularly challenging environments or for decorative purposes, it is often additionally coated. Powder coating gives stainless steel a high-quality appearance and improves protection against aggressive chemicals and extreme weather conditions.

Steel

Steel is robust, but its susceptibility to rust and corrosion makes a protective coating essential. Powder coating is a cost-effective method of maximising the durability of steel in demanding applications.
