TYPE-SWF

The SWF type expansion joint is a single-gap, watertight expansion joint system designed primarily for short- to medium-span bridges. It is engineered to accommodate small to moderate longitudinal movements caused by thermal expansion, shrinkage, and structural deflection. This expansion joint type is particularly valued for its simplicity, durability, and cost-effectiveness. The system is secured using high-strength anchors and can be prefabricated to meet specific movement ranges and bridge widths. Its surface is generally flush with the road surface, providing a smooth and quiet ride for vehicles.
