What is the most common mistake in aluminium profile ordering?

The most common mistake is ordering without a technical drawing or with an incomplete technical drawing. If tolerances, weight and cross-section details are not clear, production errors, returns and additional costs become inevitable.

What is the difference between 6060 and 6063 alloy?

6063 alloy offers higher strength, while 6060 provides better extrusion properties and surface quality. 6060 is generally preferred for architectural applications, while 6063 or 6061 is used for structural applications.

How should profile length be determined?

Order length, cut length and scrap rate should be evaluated together. Determine the effect of custom-length optimisation from the cutting plan and a verified order calculation.

What information should be specified for powder coating orders?

RAL color code, gloss level (matte/satin/gloss), minimum coating thickness (typically 60-80 microns), hanger mark location and quality standard (Qualicoat/GSB) should be specified.

Which certificates should be requested?

EN 10204 3.1 material certificate, chemical analysis report, mechanical test results and coating test reports (thickness, adhesion, salt spray) should be requested. For critical projects, mill certificate is mandatory.

How should packaging and protection be specified?

Protective film for visible surfaces, corner protectors, pallet type (wood/plastic), stacking height and special stacking instructions should be specified. For sea freight, moisture protection should be additionally requested.

How should delivery lead time be planned?

Lead time varies by project according to the profile, die, surface treatment, quantity and logistics; it must be confirmed in the quotation and order terms. For critical projects, establish a confirmed delivery plan, safety stock and an alternative supply plan.

What information should an RFQ (request for quotation) include?

Technical drawing, alloy and temper, quantity and length, surface treatment details, packaging requirements, delivery address and date, certificate requests and payment terms should be specified in the RFQ.
