Detailed description

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.

Aohong is a professional manufacturer and supplier of Strip Seal Expansion Joints, designed specifically for bridge applications requiring movement control, watertight sealing, and long-lasting durability. Strip Seal Expansion Joints consist of an elastomeric sealing strip—typically made of EPDM or neoprene—mechanically locked between two high-strength steel edge beams. These joints are ideal for accommodating structural movements ranging from 0 mm to 80 mm, ensuring optimal load transfer, water resistance, and smooth traffic flow across bridge expansion gaps.

Structure and Components of Strip Seal Expansion Joints

1. Steel Edge Beams

The edge beams are fabricated from hot-rolled structural steel conforming to ASTM A709 Grade 50 or S355 standards. Available edge beam types include C-type, E-type, F-type, M-type, and Z-type, selected based on structural requirements and installation environment. Each beam is precision-machined to maximize seal engagement and ensure skid resistance under traffic loads.
