GRP Surfaces
Safety and Functionality for Every Application
Surface Options for GRP Products
Our GRP products are available with a variety of surface finishes designed to meet different requirements for slip resistance, cleanability, and walkability depending on the intended application.
For industrial applications in wet or damp environments, corundum- or quartz-gritted surfaces are the preferred choice, offering high to maximum slip resistance (R12 to R13). Concave surfaces are particularly suitable for areas where oils and greases are present, as they combine effective slip resistance with easy cleaning. For publicly accessible areas or barefoot traffic zones, quartz-gritted and textured surfaces are commonly used. Flat-ground, profiled, or textured finishes provide especially easy cleaning, meet aesthetic requirements, and, depending on the design, are also suitable for indoor or decorative applications. This ensures that the right combination of safety, functionality, and design is available for every application.
Concave Surface (K)
The concave surface is the standard finish for molded GRP gratings. It is created during the manufacturing process as the liquid resin cures. Depending on the bar thickness and mesh size, slip resistance ratings of R12 or R13 are achieved.
The concave surface is suitable for all industrial applications where slip-promoting substances such as oils and greases are present. If required, it can be cleaned easily.
