"Tired of shoveling snow, or of trips and falls in the workplace due to snow and ice? HeatTrak, a US company that manufactured heated matting products for commercial and industrial use, has developed a product line of walkway and stair mats in a variety of standard dimensions that can meet the needs of any business of facility. HeatTrak can also customize heated mat systems to meet more specific dimension requirements.
The mats are made of rubber, are placed on top of existing surfaces such as sidewalks, and may be left outside for an entire winter season. The company also makes electrically heated stair treads designed to prevent snow and ice accumulation on exterior stairways."
