Fasten Line

The modular profile system that builds it all

Fasten Line is more than modular profiles: it’s the backbone of versatile, long‑lasting structures. Manufactured from high‑quality structural aluminium, Fasten Line adapts to any industrial project thanks to its compatibility and flexibility.

It’s our most standard, robust, and versatile system, with 10 mm slots and an M12 threaded core—plus 8 mm and 6 mm versions for lighter builds.

High‑performance profiles

At Fasten, we understand tight deadlines and the importance of precise fit. That’s why we manufacture our profiles 100% in Spain, in 6060 or 6063 alloys with T5/T6 temper. Combine them with our accessories to build any type of structure or industrial equipment.

Optimized for 10 mm slots with M12 threaded core—as well as 8 mm and 6 mm—our modular profiles offer versatility, strength, and a wide variety of special sections. Now also available in different colours for a functional, aesthetic finish!

We also offer a broad assortment of connectors, plates, joints, and fixings for fast, safe, machining‑free assembly.
