The G-Floor Diamond Tread Gas Grill Mat is designed to withstand grill heat and messes while protecting wood decking and concrete patios. While many grill mats buckle under the pressure of heavy grills and melt under intense heat, this top quality 100% polyvinyl mat is strong enough to park a car on and tough enough to brave harsh outdoor conditions and the most zealous grill master. The grill mat is ideal for a multitude of spaces - patio, balcony, dock and deck - and with a high heat tolerance, works great with: gas grills, large electrical grills, steamers, barbecues, outdoor fryers and more. Spend more time enjoying cooking and less time cleaning up because the mat requires just a light scrub for tough stains and in most other cases, a simple spray down with a hose. Because this grill mat is water-, mold- and mildew-proof, you're sure to find additional outdoor uses for this highly versatile mat. Diamond Tread's standardized diamonds are 1.125 in. in length and 0.625 in. apart with a 0.030 in. relief, aligned diagonally in a 180 degree alternating pattern.
