Rubber-Cal's "Coin-Grip Grit Surface" commercial rubber stair treads are designed to prevent slips and improve safety for those traveling on commercial staircases. Made from an eco-friendly blend of natural and reclaimed rubbers materials, these non-slip treads have increased durability and perform well on interior and exterior staircases alike. Reclaimed rubber has great resistances to abrasion, moisture, and UV rays, ensuring these step mats are ready for anything from daily foot traffic to heavy rainfall. The surface of the tread mats features a pattern of stud-like protrusions for a professional aesthetic and improved traction. The main feature of these rubber treads, however, is their gritty surface texture. Unlike our regular "Coin-Grip" stair mats, this design includes a black emery grain surfacing that feels similar to sandpaper. The rough surface drastically enhances traction when traveling up or down the rubber steps. This traction can be maintained even when the rubber step covers are wet. And thanks to the durable reclaimed rubber materials, these outdoor stair treads are impervious to moisture-effects like mildew and mold. The slip-resistant treads can be installed outdoors with very little maintenancecleaning can be done easily with soap and water. These no-slip treads measure 10" x 36" to fit most commercial steps, with a 1.6" latch for secure placement. These rubber stair covers are sold in packs of 6 and designed for easy DIY installations. Whether needed seasonally or year-round, the "Coin Grip Grit Surface" rubber stair treads are a dependable way to increase stairway safety.
