Question 1

How does a call-off against an annual volume work?

Accepted Answer

You indicate an annual volume; we plan production slots and you release per period. Quantities, revisions and release moments are set out per contract or quotation, and lead times are confirmed project by project.

Question 2

Do I become the owner of the die?

Accepted Answer

That differs per situation. Arrangements on the use and management of the die for your OEM orders are set out explicitly per contract or quotation; we deliberately make no blanket ownership claim.

Question 3

How do you ensure every batch is identical?

Accepted Answer

We work from a recorded drawing with a revision number and deliver consistent QA documentation per batch, including dimensional inspection against that drawing. Any change always runs through a controlled revision.

Question 4

What minimum quantity applies to OEM profiles?

Accepted Answer

Custom extrusions typically start from 500 kg per profile as a reference; larger or production-dependent profiles may require more. Smaller quantities apply only to genuinely standard catalogue profiles, subject to quotation confirmation.

Question 5

Who holds the certificates?

Accepted Answer

The production certificates (ISO 9001:2015, ISO 14001, QUALICOAT, QUALANOD, EN 755, EN 12020) are held by certificate holder Ersaş Aluminium. GBS ALU handles the commercial and logistics side and the CBAM declaration.

Question 6

Which countries do you deliver to?

Accepted Answer

We deliver to the Benelux, the Nordics and the rest of Western Europe. EU import, customs and CBAM handling run through GBS ALU, with a single Dutch or EU invoice.

Question 7

Can CNC machining and finishing be in the same delivery?

Accepted Answer

Yes. Profiles are delivered CNC-machined and finished (powder coating or anodising), so you receive an assembly-ready part in one delivery instead of a semi-finished profile.
