The snow melting mats feature innovative graphene heating technology that melts snow at 3 inches per hour (122°F) on concrete, asphalt, stone, or wood decks. Made of durable, anti-slip rubber with waterproof and energy-efficient construction, they come in 3 sizes and include an 11.5 ft power cord with UL-listed plug for easy installation. Ideal for stairs, sidewalks, walkways, and roofs, graphene's high conductivity and mechanical strength provide fast, reliable, and long-lasting winter snow removal.
