Shredder grates for wood and bark applications operate in brutal conditions. Sand, rocks and tramp metal add to the harsh environment found in these shredding applications. CXS grates are fabricated and formed from quenched and tempered steel plate that is through hardened and free of soft spots. This allows for long life and even wear. Custom designed cutting edges are available on some grate styles to aid in cutting stringy bark such as Cedar or Basswood.
