From drawing to quote, fast, for aluminium extrusion profiles

An alloy and surface-finish guide, weight calculator and one-form quote request for box, angle, T-slot, heat sink and architectural profiles.

Roadmap for a custom profile

A custom-section profile project usually passes through these stages.

  1. Drawing and requirementsSection drawing, application, alloy and surface expectations are defined.
  2. Die and sampleA die is prepared for the section; a sample confirms dimensions and appearance.
  3. Extrusion and coolingThe heated billet is pushed through the die; the profile is cooled, stretched and cut to length.
  4. Surface and secondary workAnodizing, powder coating, drilling or cutting are planned per request.
  5. Packing and shippingThe profile is packed to protect its surface and delivered.

Scope and lead times are confirmed in writing in the quote.

Frequently asked questions

What is aluminium extrusion?

Aluminium extrusion is a forming process in which a heated aluminium billet (a cylindrical log) is pushed under high pressure through a shaped die to create a profile with a constant cross-section. The die opening defines the cross-section; the profile is then cooled, stretched, cut to length and, if required, aged.

What is a billet?

A billet is the heated, cylindrical aluminium log of a specific alloy that is loaded into the extrusion press. The alloy of the profile is set by the alloy of the billet; the most common alloys are EN AW-6060 and EN AW-6063.

What is the difference between 6060 and 6063 alloy?

Both belong to the Mg-Si (6xxx) family and suit anodizing and painting. 6060 extrudes easily in thin walls and detailed sections and is used for general purposes; 6063 is known for surface appearance in architectural profiles. The choice depends on the section, surface treatment and required mechanical values, and is confirmed in the quote.

How is profile weight calculated?

Kilograms per metre = cross-section area (mm²) × 0.0027, using a density of about 2.70 g/cm³. Example: a 40×40×2 mm box section has an area of 304 mm² and weighs about 0.82 kg/m. The calculator on this site does it automatically; section tolerances can cause small differences in real weight.
