Materials
What we cut, and how we finish it.
Mill certificates on every bar and plate, heat numbers tracked through the job, and a certificate of conformance with every shipment.

Sourcing
We buy from mills and stockists with a paper trail, and we keep common aluminium and stainless in the rack so a prototype is not waiting on a delivery. Customer-supplied material is welcome, counted in and counted out.
Finishing partners
Anodising, plating, heat treatment and passivation go to certified partners we have used for years, with their certificates attached to ours. Deburring, tumbling, bead blast and passivation are in house.
