bi-Trapez Bearing® is a non-reinforced, profiled elastomeric bearing shape dependent loadable, up to 17.4 N/mm² and with controlled material grade. The main component is an ageing resistant EPDM elastomeric material with a hardness of 65 ± 5 Shore A. The bearing is available in different thicknesses.
bi-Trapez Bearing® provides highly effective insulation against structure-borne sound and vibrations and is permanently elastic. This bearing is primarily used for structural members of all types and for impact sound mitigation in stair and landing components.
The bi-Trapez Bearing® can be used in cast in situ concrete as an impact sound stop stair component with a top-side cover.
