Our Medium Duty dumptruck liner is manufactured from a high molecular weight (HMW) polyethylene extrusion. This plastic liner is designed for lighter hauling, and is subsequently priced more cost-effectively than our heavier duty dumptruck liners. The Mid-Grade dumptruck liner ranges from 1/4” to 1/2” thickness, and can be manufactured in widths from 1’ to 16’. We recommend against hauling any asphalt with this grade of dumptruck liner.
