Rubber neoprene bearing pads is used extensively in construction industry. Besides being widely used in bridge, construction or other supports, they are also specified in wide variety of applications where flexible structural support and vibration isolation is required.
We offer our clients a wide range of Elastomeric bridge Bearing pads which is using superior quality steel plates and high grade chloroprene or natural rubber. The Rubber hold up flat to pressurize into sulfide by multi-layer rubber and stencil plate, it can move the upper structure of the bridge to piers reliably against strength also can adapt to roof beam end rotate and provide support through rubber shearing deformation of flat.
