Strip Seal Expansion Joint STEEL-SLIDING-PLATE-001

The Modular Bridge Expansion Joint System represents the pinnacle of modern bridge engineering technology, specifically designed to accommodate large thermal movements and structural deformations in long-span bridges and complex infrastructure projects. This advanced expansion joint system utilizes a modular design philosophy that allows for customization based on specific project requirements, making it an ideal solution for highway bridges, railway overpasses, and urban infrastructure developments. Our modular expansion joints feature precision-engineered steel support beams combined with high-performance EPDM rubber seals, creating a robust and durable system capable of withstanding extreme environmental conditions and heavy traffic loads. The modular configuration consists of multiple center beams, support bars, and control boxes that work in harmony to distribute loads evenly across the bridge deck while maintaining smooth vehicular passage. **Design Standards Compliance:** This product fully complies with both European Standard EN 1337-3 (Structural Bearings - Part 3: Elastomeric Bearings) and American Standard AASHTO M 251 (Bridge Expansion Devices). Our manufacturing processes adhere to ISO 9001:2015 quality management systems, ensuring consistent product quality and performance. The design incorporates seismic resistance features that meet EN 15129 requirements for anti-seismic devices, making it suitable for earthquake-prone regions. **Technical Specifications:** - Movement Capacity: 80mm to 1200mm (customizable) - Load Rating: HL-93 and HS-20 truck loading - Material: Q345B structural steel with hot-dip galvanizing - Rubber Seal: EPDM compound with Shore A hardness 60±5 - Temperature Range: -40°C to +80°C - Design Life: 30+ years with proper maintenance - Waterproofing: IP67 rated sealing system **Application Scenarios:** This modular expansion joint system excels in various infrastructure applications including cable-stayed bridges, suspension bridges, continuous beam bridges, and curved bridge structures. It is particularly well-suited for projects requiring large movement accommodation, such as bridges spanning wide rivers, coastal bridges subject to temperature extremes, and urban elevated expressways with high traffic volumes. The system has been successfully implemented in over 500 major bridge projects across 45 countries, demonstrating its reliability and versatility in diverse environmental conditions.
