STABLE AND ANTI-SHIFTING: With built-in screw slot design, it can be permanently fixed in garages, supermarkets and other places with expansion screws. Effectively prevent the ramp from moving and ensure stability for long-term use PREFERRED MATERIAL: The ramp is made of rubber, which is not easy to deform and can be used for a long time. If it needs to be used indoors, it is recommended to unpack it outdoors and ventilate it for one day before use GRID BASE DESIGN: The grid base can disperse pressure and improve bearing capacity, with a load capacity of up to 5 tons, suitable for use in trucks, cars, motorcycles, carts and wheelchairs ANTI-SLIP AND DRAINAGE: The concave and convex surface design enhances friction in rainy and snowy weather, effectively preventing slipping. The water outlet at the bottom quickly diverts accumulated water and prevents odor, taking into account anti-slip safety and hygienic maintenance The surface of the wheelchair ramp is designed with anti-skid grooves, which form a drainage path and increase friction, effectively preventing slipping, falling and scratching.
