Glass fiber reinforced plastic (GRP) is a composite material consisting of a synthetic resin and embedded glass fibers. This combination gives GRP high strength and low weight, making it a versatile material in many industries.
The advantages of GRP include excellent corrosion resistance, high mechanical strength and good formability. These properties make GRP an ideal material for demanding applications where durability and resistance are required.
The GRP Material
Our cover systems consist almost exclusively of glass fiber-reinforced synthetic resins. These materials and their advantages have been known for many years: high strength, light weight, chemical resistance, good colorability and UV resistance, best possibilities for shaping. Extreme resistance to weathering and ageing - the covers we supplied more than thirty years ago are still in use today.
We process fiber-reinforced plastics using the hand-laminating process, among other methods. In this process, glass fiber mats are impregnated with plastic resin and then rolled by hand in several layers into a structural form.
We incorporate glass fibers in the form of mats, fabrics and fleeces strictly in accordance with static calculations with appropriate safety features. Stainless steel is used for connecting elements. We carefully seal cut edges, drill holes etc. to reliably prevent moisture from penetrating the laminate.
Integration of photovoltaic systems
GRP covers are ideal for integrating photovoltaic modules—both in new installations and retrofits. Because they have a similar coefficient of thermal expansion to PV film modules, they can be securely bonded to the GRP, resulting in a stable, durable, and low-maintenance solution. The UV-resistant surface also ensures long-term, reliable PV performance without deformation or delamination due to thermal stress.
