Question 1

Which anodised colours can I request?

Accepted Answer

Natural, black and bronze are common request directions. The exact shade, pre-treatment, gloss, suitability for the profile and batch availability are confirmed in the quotation and product specification.

Question 2

Which anodising thickness do I need?

Accepted Answer

This depends on indoor or outdoor use, atmospheric exposure and the project specification. Architectural classes such as 10, 15, 20 or 25 microns can provide a starting point; the final class is documented after technical review and in the quotation.

Question 3

What is the MOQ for custom anodised profiles?

Accepted Answer

For custom extrusion, 500 kg per profile is typically the starting reference. Larger or production-dependent profiles may require a higher MOQ. Smaller quantities are possible only for genuinely standard items and are always subject to quotation confirmation.

Question 4

Can a black or bronze anodised batch be repeated exactly?

Accepted Answer

Batch-to-batch colour variation can result from material, geometry and process variation. Supply reference samples, visible-face requirements and acceptance criteria; the feasibility of a colour match is assessed for each enquiry without an unlimited matching guarantee.

Question 5

Can the inside of a hollow profile be fully anodised?

Accepted Answer

Not to the same extent as freely accessible outer surfaces: electrical current and bath access limit layer build-up in hollow chambers. Mark functional inner surfaces on the drawing so technical suitability can be reviewed in advance.

Question 6

Who manufactures and who holds the certificates?

Accepted Answer

Ersaş Aluminium manufactures and anodises and holds the Qualanod and ISO 9001:2015 certificates. GBS ALU manages the commercial order and can, where the agreed order model, contract and Incoterms provide for it, manage import, CBAM coordination and logistics; responsibility and cost treatment are confirmed in the quotation or order terms. GBS ALU does not hold these production certificates.

Question 7

What information is needed for a quotation?

Accepted Answer

Send a DWG, DXF, STEP/STP or PDF with alloy, temper, length, tolerances, visible faces, anodising colour, required class, annual or batch demand and delivery location. Availability and planning are then confirmed by quotation.
