Zetwerk provides a complete range of surface finishing treatments for all or portions of each metal component’s surfaces. Surface finishing is quite common and is required to prevent surface corrosion and/or improve the appearance of the part.

Some surface finishes and surface treatments provide enhanced electrical or mechanical properties that add to the overall functionality of the metal component. Metal components requirements often involve cosmetic surface finishes and these finishes can involve highly cosmetic surface requirements. When these high surface-quality finishes are required there are additional costs involved in their application and subsequent protective packaging.

Surface Finishing Options, a partial list

There are many surface treatments and finishes available and it’s not uncommon for metal parts and components to require a combination of surface treatments such as surface plating for enhanced corrosion resistance and then painting (powder or wet spray, etc.). Whatever the requirement, Zetwerk can provide surface treatments to meet every application and requirement. Here is a partial listing of surface finishing options available.
