Neoprene Bearing Pad As efficient bearing plates for pre-cast, pre-stressed concrete or steel beams in bridges and buildings. Neoprene pad-plain and laminated-manufactured by Maruti permits a smooth and uniform transfer of load from the beam to the substructure and allows beam rotation at the bearing due to deflection of the beam under load. They further allow lateral and longitudinal movement of the beam caused by thermal forces.
Neoprene pads have no movable parts and thermal expansion and contractions are observed by the pads enable to give and take in shear. There is no solid motion between pad and beam or between pad and abutment. Lab is equipped with latest instruments like Tensile Tester, IRHD hardness Tester, Tension set Apparatus, Air oven, Muffle furnace, humidity chamber, High voltage tester, Bi-Axial testing machine, all instruments are calibrated from NABL certified lab.
