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.
