With in-house tooling capabilities, Silex can produce extruded profiles and sections in a massive range of material grades (including solid, sponge or foam), hardnesses, colours and sizes to your specifications. 

Where a replacement for an old or expired profile is needed and the material or dimensions are unknown, we can produce sections to match by using a small sample. 

We offer lead times from 6 weeks, with minimum order quantities from as little as 25m.
