Characteristics Exceptional behavior in the face of bad weather. Resistant to humidity: almost zero water absorption. Does not deteriorate or rot like wood: microorganisms do not affect the material. Stability against ultraviolet radiation. Possibility of producing a wide range of colors. No need for surface treatments, such as primers and paints, not requiring maintenance. Greater effort / weight ratio than aluminum and steel. Its weight comes to be 2/3 of the aluminum and 1/4 of the steel. Higher impact resistance than ceramic materials. High thermal working range. It maintains its mechanical and electrical properties between -70 ° C and 200 ° C. Dimensionally stable. Both the rigidity and flexibility of the materials can be adjusted during the process. High mechanical resistance. This depends on the composition of the reinforcing material. All profiles contain self-extinguishing additives and have a low level of smoke generation – Class M2 – degree of reaction to fire. Can be manufactured with very low flammability coefficient – class F1.
