All of the materials we use are stringently tested and of the highest quality

It is possible that different fibre types serve as the base for our products. Carbon fibres are the most commonly used, but various types of glass fibre are also applied by DPP. Carbon fibre does not oxidise under the influence of water and oxygen. Carbon has a considerably lower density than steel, a high tensile strength and low coefficient of expansion. These properties make carbon-fibre composites very suitable for applications that require a low weight, high strength and high rigidity.

The carbon and glass-fibre profiles have good fatigue resistance and are excellently resistant to acids, salt, water and most chemicals. The material does not corrode and absorbs little moisture. Moreover, the products have interesting thermal and electrical properties. They also have good adhesive properties and are maintenance-free.
