Bridge Strip Seal Expansion Joints
Price:
Strip Seal Expansion Joints, also referred to as single strip seal joints, are engineered bridge expansion systems composed of elastomeric sealing elements and steel edge beams. The elastomeric strip, typically manufactured from durable EPDM or neoprene rubber, is securely locked within grooves in opposing hot-rolled steel edge profiles—available in multiple configurations such as C, E, F, M, and Z types. Designed to withstand heavy vehicular loads, these joints provide reliable watertight performance while accommodating structural movement ranging from 0 mm to 80 mm. Commonly used in bridges, highways, and concrete deck structures, strip seal expansion joints offer a robust and cost-effective solution for managing thermal expansion, vibration isolation, and sealing needs in small to medium movement applications. The steel components conform to standards like ASTM A709 Grade 50 or S355, while the rubber strip seals meet ASTM D5973 specifications, ensuring long-term durability and structural safety.
