ErgoDeck Solid with GritWorks! is used in areas where over spray or tracking of grease and oil cause slip hazards. 18" x 18" solid, super-sized ergonomic tiles is the most advanced, professional-grade, ergonomic matting system on the market today. These larger components quickly and easily cover large areas and require less time and labor to install. Tiles are incredibly substantial, and are designed with an excellent durometer to prevent standing worker fatigue, and encourage productivity. The tiles are engineered to withstand cart traffic of up to 64 psi - the equivalent of a 300 lb. cart with 4" diameter wheels - and heavy usage. The GritWorks! surface provides exceptional traction in areas with overspray or tracking of grease and oil, yet still accommodate wheel traffic. ErgoDeck has LockSafe , a patented and totally effective, interlocking system that quickly "locks" tiles together, and keeps them together despite constant use. The tiles are accurately aligned for a neat, and seamless floor without maintenance or safety headaches.
