GRP sheet for plant engineering
GRP (fiberglass) sheets are lightweight and also strong and durable. They do not corrode, are easy to machine as well as electrically insulating. Due to these properties, they have a very flexible field of application and offer a variety of advantages over sheets made of conventional materials such as aluminum, metal, wood, or thermoplastics.
The surface is smooth on one side and the reverse side is matte.
Dimensions
The panel is available in 2.990 mm width and thickness of 1.0, 1.2, 1.5, 1.8, 2.0, 2.5, 3.0, 4.0, 5.0 and 5.5 mm.
