INDUSTRIES SERVED: Highway, Railway, Municipal
Our Polyurethane Bridge Bearing Pads are expertly engineered by Pepsen, a leading China manufacturer and supplier specializing in urethane load-bearing solutions. These pads outperform traditional rubber and elastomer alternatives with superior abrasion resistance, tensile strength, and long-term structural stability. The cast urethane formula delivers consistent performance in demanding environments, giving buyers a product that’s durable, reliable, and cost-effective. All urethane pads are cast in one piece, with smooth surfaces and no bubbles or defects.
OEM service is fully supported in our factory, and our polyurethane bridge bearing pads are widely used in highway, railway, municipal bridge construction projects, as well as seismic zone and river-crossing bridge engineering. We also cater to precast concrete and steel structure bridge projects, providing customized solutions for different infrastructure construction needs.

- Applied in industrial structures, absorbing vibration and dynamic loads.
- Compatible with pre-cast concrete and prefabricated components.
- Ideal for OEM projects requiring custom performance solutions.
- Resistant to water and aging, adapting to various outdoor harsh environments.
- Higher vertical load capacity than traditional rubber bridge bearing pads.
- Excellent low temperature resistance for cold region bridge applications.
- Strong bonding with metal plates, no cracking or peeling during use.
- Good damping effect to reduce bridge vibration from traffic and wind.
- Long service life with normal maintenance and operation.
- Smooth surface finish meets strict bridge construction quality standards.
- UV Resistant Polyurethane: Ideal for Outdoor Applications
- Southeast Asian highway construction client faced the problem of rubber bearing pads failing to withstand heavy traffic load and frequent replacement. We provided custom cast 85A polyurethane bridge bearing pads with a vertical load capacity of 8000kN, which perfectly matched their bridge design parameters. The pads have been in use for 3 years with no quality issues, reducing the client's maintenance cost by 60% and improving the bridge's overall stability.
- A European municipal engineering client needed bearing pads for seismic zone overpass construction, requiring excellent shear resistance and low temperature adaptability. Our cold-type polyurethane bridge bearing pads (-50℃~60℃) with a damping ratio of 15% were customized for them. The pads effectively absorbed seismic forces during a small local earthquake, protecting the bridge structure from damage and winning high recognition from the client.
- A domestic China railway bridge client had the demand for quick delivery of bearing pads for a rush project. Our factory completed the production of 200 sets of custom cast urethane bridge bearing pads in 15 days with OEM service, meeting the client's construction schedule. The pads' precise size and perfect fit with the bridge structure ensured the smooth progress of the railway project.
