Graepel-Perl is a C-shaped, canted metal profile grating with closed surface. The name derives from the pearled, hemispherical upward perforations. They are arranged in staggered rows and have a diameter of 5 mm. The perforation offers a certain anti-skid effect and displacement, but no drainage. The maximum width of the perforated area is 475 mm for gratings with an interrupted perforation pattern, and 625 mm for gratings which have been fully perforated.
Metal profile gratings of Graepel-Perl perforation are especially suitable as covering for surfaces and platforms in public and industrial areas where closed surfaces are required. Especially recommended is the indoor use. Graepel-Perl allows no view through it. This perforation is ideal for places where nothing should drop through and where finer (non-industrial) shoes are worn.
This perforation is even suitable for barefoot walking. The stainless steel type is suitable for use in swimming pools.
