Surface treatment

Surface treatment of springs and components

Surface treatment

For particularly high-quality springs and structural elements, CARL HAAS offers a wide range of surface treatments, from electroplating with precious metals such as gold, silver, copper, zinc and nickel to greasing and zinc flake coating.We also offer bonding surfaces as standard.In addition, you can also specify the color, conductivity and surface protection you require.

Galvanic surfaces are used to improve the conductivity, contact transfer, reduction in resistance and color coding of the spring and structural elements.

With galvanic surfaces, we finish your products to your requirements
