Product Description

Product Description

Plate expansion joints are elastic connection devices designed for engineering structures such as bridges and roads. They are made of high-strength steel and can effectively absorb structural displacement caused by temperature changes and load vibrations through the mutual sliding and deformation of laminated steel plates or comb-tooth steel plates.

Its core features are strong durability, high pressure-bearing performance, and easy installation. It can adapt to multi-directional displacements such as longitudinal, lateral, and torsion. It also has excellent waterproof and dustproof design to extend the service life of the road surface. It is suitable for large-span bridges and heavy-load traffic scenes. The surface can be treated with anti-slip treatment to ensure safe and smooth driving. It is an indispensable expansion joint solution in modern transportation infrastructure.

Application

Plate expansion joints are widely used in civil engineering projects such as bridges, roads, and tunnels. They effectively absorb structural expansion and contraction caused by temperature changes, load effects, etc., ensuring the stability and safety of buildings. At the same time, they provide good waterproof performance and driving comfort, extending the service life of the structure.
