texture Metal Surface Finishes

Electropolish

The surface is submerged in an electrolyte bath while exposed to a rectified current in order to remove surface flaws. Also known as the “Reverse Plating Process”, the finished surface exposes the virgin material.

Passivation

The surface is treated with an oxide layer to draw out impurities and to reduce corrosion. It also increases the stability of the surface and protects against possible contamination.

3A (Sanitary Finish)

The surface is free of dents and scratches which produces a mirror-like finish. The smooth surface can be cleaned easily to create a sterile environment and is recommended for use in the food, beverage and medical industries.
