Graepel-Stabil is a C-shaped, canted metal profile grating. Its surface is characterized by 45 mm long, raised holes in olive shape with serrated edges. The profile height is 9 mm; the open area amounts to approx. 50 %. Despite its wide displacement space and an enormous drainage effect, this perforation has a 15-mm blocking. (A ≥ 15 mm ball will not drop through.) Graepel-Stabil has been certified the highest slip resistance class. Due to the large embossing height, Graepel-Stabil has a high transverse stiffness of the grating surface which makes perforation group widths of up to 886 mm possible.
This perforation is universally used as safety grating on surfaces, walkways and platforms. It is designed for outdoor applications as its slip resistance is less affected by snow and slush. The use of Graepel-Stabil is advisable in the field of renewable energies as well as in the onshore and offshore sectors.
