Design

Choice of material thickness

The thickness of the material is determined by the degree of strength required and by the desire to produce the extrusion as cost-efficiently as possible.

An extrusion of uniform thickness is easiest to produce. The extrusion technique makes it easy to vary the thickness when necessary.

Production economy
From a financial perspective, it is always best to design the profile so that production is facilitated.

A profile is easier to extrude if:

• the wall thickness is identical
• it uses simple, soft forms with slightly rounded corners
• it is symmetrical
• has a small, circumscribing circle
• it does not have deep, narrow gaps
