CONTROLLED SURFACE SYSTEM
Overview
A surface engineered around the part.
A high-performance trivalent chromium chemistry designed to satisfy strict RoHS and environmental directives while offering robust corrosion protection and paint adhesion.
Our process planning considers alloy series, machining condition, dimensional sensitivity, racking position, visual zones and service environment before production begins in our Rajkot plant.
