Drawing Review & Die Making
We evaluate your 2D/3D drawing or sample, recommend alloy and finish, and develop the custom extrusion die in-house.
Billet Casting
Aluminum billets are cast in-house, giving us control of raw material from the very first step.
Aluminum Extrusion
Profiles are extruded on 15 lines from 600 to 1,800 tons, covering small precision sections to large structural profiles.
Surface Treatment
Anodizing, electrophoretic coating, powder coating, wood grain transfer and polishing on our own finishing lines.
CNC Machining & Cutting
Cut-to-length, drilling, milling and CNC machining turn profiles into ready-to-assemble components.
Sample Approval & Mass Production
