Trio-Ply belts are constructed with three fabric plies. Trio-ply belts are available for tensile strengths, starting from 400 to 1900 N/mm. These belts are specifically resilient to impact and tear due to its thicker skin rubber construction.
If the drum diameter is suitable, 3 ply belts are recommended, following the minimum ply concept. These belts are available for all cover grades, including heat resistant, flame resistant, oil resistant, acid resistant and cold resistant.
