Romplast, with Patent No. 0001411276, completely solved the problem of warping caused by thermal expansion by using plastic reinforcement instead of metal.
This technique, extremely resistant to atmospheric and mechanical agents, does not increase the weight of the roller shutter and can be applied to any profile requiring reinforcement.
This method respects the environment by completely recycling all materials used. The main body of the splint is made of a polymeric material (PVC) and must have internal parts reinforced with a non-metallic polymer material to increase flexural strength.
The two types of materials are extruded simultaneously using a standard co-extrusion process. The main body can also be coated with a UV-resistant material (SKIN) to provide this protective feature, and this process also occurs via co-extrusion. The two co-extrusions are carried out simultaneously with the extrusion of the main body.
