For concrete plants, liners and wear parts are designed to fit common wear areas in most brands of plant — including the central mix drum and blade liners, turn-head liners, hopper and bin liners, scale liners, and dump chute liners. Urethane products are long-lasting and much lighter than steel, allowing for easier handling and installation. Any necessary trimming can be handled in place with a sharp knife or reciprocating saw. Steel does not allow cutting in enclosed areas, requiring removal of the liners for adjustment.
