Our Heavy-Duty liner is manufactured from an ultra-high molecular weight (UHMW) polyethylene extrusion to produce a plastic liner designed for heavy-duty hauling. When compared to HMW liners, UHMW liners are 3-5X more resistant to wear. Heavy-Duty liners are suitable for larger rock and heavier hauling. The Heavy-Duty liner ranges from 1/4” to 3/4” thickness, and can be manufactured in widths from 1’ to 16’ feet wide. We recommend against hauling any asphalt with this grade of liner. This liner can withstand temperatures up to 180 degrees Fahrenheit.
