Metal Finish

Huada provides a diverse selection of metal finish options, ensuring your parts are both durable and aesthetically appealing.

Metal fabricated parts can undergo two types of finishing processes: metal finishing and surface finishing. Metal finishing is adding a layer to the material. While surface finishing entails removing a layer from the material. Both types of finishing are aimed at improving both the appearance and functionality of the parts.

Functional coatings are commonly selected to safeguard sheet metal against corrosive elements and physical damage. However, they can also enhance other properties such as weldability, electrical conductivity, resistance to chemicals, and more. On the other hand, aesthetic choices in surface finishes are often driven by desired appearances or branding objectives.
