Full definition
Rubber flooring sheet with parallel raised linear ribs (channels) running along the length, designed to drain water away from the walking surface and provide directional traction. Rib spacing: typically 6-12 mm center-to-center. Rib height: 1-3 mm above the channel bottom. Total sheet thickness: 3-6 mm. The channels between ribs provide drainage pathways that keep the walking surface drier, while the rib tops provide a non-slip contact area. Static COF typically exceeds 0.7 (well above the ASTM D2047 minimum of 0.5). Materials: SBR (standard, economical), NR (better abrasion resistance for heavy traffic), or neoprene (oil + weather resistance for outdoor use). Applications: building entrances (captures water from shoes), vehicle wash areas, loading docks, factory wet areas, pedestrian ramps, pool surrounds, and any surface subject to frequent water or liquid spillage. Installation: adhesive-bonded to concrete or loose-laid with border trim. Standard widths: 1,000-1,500 mm rolls, lengths 5-15 m. Also available in fine-ribbed (cosmetic) and wide-ribbed (heavy drainage) versions. Brands: Rubber-Cal, Regupol, Nora.
