Better than wood

The thermoplastic composite materials developed by Quadrant are finding increasing use in the construction industry because they are in many respects markedly superior to wood, the classic material. They are above all light, weather-insensitive, dimensionally stable and non-rotting.

Quadrant has therefore developed MultiQ, a solid thermoplastic composite panel, by resorting to two proven polypropylene-based materials. Used as formwork panels or scaffold planks, they boost economic efficiency on the construction site thanks to their long service life.

The innovative sandwich board has a core made of SymaLITE, while the cover layers consist of high-strength, thin and UV-resistant GMTex. In the production of MultiQ, the two sheet-like semi-finished products are welded together into 9 to 22 mm thick sandwich panels through the application of heat. The surface of the new composite is homogeneous and smooth. The special combination of multi-directional glass fibers in the core and cover layer fibers oriented in the direction of tension and compression yields the desired high material stiffness with a low weight per unit area.

The MultiQ product line is a modular system. The composition and thickness of the fiber composite panels offer plenty of scope for variation and permit design to customer specification. Quadrant makes it possible to have panels produced in different colors and sizes up to a maximum size of 2.4 x 3.5 m.

 
Formwork
Conventional formwork panels made of plywood swell, discolor, rot and have to be very carefully cleaned so that they achieve the desired quality of concrete surface during their service life of 50 to 80 uses. The fundamental problem is that any moisture penetrating into the wood has a negative effect on the panel's technical and mechanical properties.
