04Three confirmations before production
Can we make it?
The section is identified as stock or made-to-order, and the alloy confirmed for your use.
Machining & finish agreed
Cut lengths, any drilling or turning, and mill or anodized surface are written into the quote.
Proof before shipping
Dimensions and straightness are checked against the agreed criteria, certificates included as needed.
Machining and surface treatment happen here, in the same plant — CNC & machining · Finishing.

06Frequently asked questions
Stock sections or extrude-to-order?
Common sections move as stock; anything else is extruded to your drawing. Dimensions and quantity in the RFQ tell us which shelf — or which press — your order comes from, and the quote says so.
Best alloy for parts we'll machine ourselves?
6061 and 6082 cut cleanly and hold strength; 6060 and 6063 suit lighter, form-heavy work. If you tell us the part instead of just the bar, the recommendation covers temper too.
Cut-to-length with a straightness spec — possible?
Routine. State the acceptance criterion — straightness per metre, end-cut squareness, cosmetic class — and it is quoted and tested as written, not interpreted later.
What's the minimum quantity?
It varies by section and alloy, so we would rather price your actual numbers than publish a figure that misleads. Sizes plus quantities gets you a real minimum by return.
