When forming the slab, work is completely carried out from a safe position below; the panels are simply hooked in and then pivoted upwards.

DUO System Formwork

Efficiency & Versatility

The intuitive and quick application enables crane-free handling, while versatile and lightweight components reduce transport requirements.

The latest panel formwork system in our product portfolio is made from technopolymers, making it 100% recyclable. With no component weighing more than 25kg, DUO can be manoeuvred around construction sites with ease. Optimisation is a key benefit of the system’s design, as it can be used to form walls, columns and slabs with reduced tooling requirements.

A sustainable option for any construction project, the formwork system reduces the output of waste as it is reused in the production of new panels and components.
