Matrox™ Our premier liner for all applications, including asphalt. Matrox™ has the impact strength, slickness and abrasion resistance required for all aggregate loads, but is also designed to withstand loads as hot as 350° degrees F. Matrox™ is backed by a two year warranty when properly registered with the manufacturer. Ramex® Black Our Premium Grade Aggregate Liner. Ramex® Black offers high impact resistance as well as great release properties. This makes Ramex® Black ideal when loading gravel, coal and grain and a must when loading shot rock, boulders and demolition. Because of the added toughness, Ramex® Black is backed by a two year warranty when properly registered with the manufacturer. Ramex® Reprocessed Offers equal abrasion resistance and slickness as Ramex® Black, but lesser impact strength at a more economical price. This makes Ramex® Reprocessed ideal when loading lime, sludge, gravel and other low impact materials. Ramex® Reprocessed is backed by an 18 month warranty when properly registered with the manufacturer. Symplate™ Some lining applications do not require significant impact strength. Sand, mulch and leaves are abrasive and sticky but they they carry lower impact during loading. This makes Symplate™ an affordable solution to material flow and abrasion problems. Symplate™ is backed by a 12 month warranty when properly registered with the manufacturer. Only Matrox™ is designed for Asphalt handling. A single load of hot asphalt in a Ramex® Black, Reprocessed or Symplate™ liner will destroy the liner and void the manufacturer's warranty.
