About strip seal expansion joints

Heres a precise product description for bridge strip seal expansion joints suitable for technical documentation or catalogs:

Product Name: Bridge Strip Seal Expansion Joint

Description

The bridge strip seal expansion joint is a durable and flexible joint system designed to accommodate thermal expansion, contraction, and structural movements in bridges and elevated roadways. It consists of a continuous neoprene or EPDM rubber seal fixed between steel edge beams, which are securely anchored into the concrete deck. This design ensures watertight sealing, prevents ingress of debris, and maintains the structural integrity of the bridge under heavy traffic loads.

Key Features

• Seal MaterialHigh-quality neoprene or EPDM rubber for flexibility and long life

• Steel ComponentsGalvanized or stainless steel anchor beams for durability

• Movement CapacityDesigned to accommodate longitudinal, transverse, and rotational movements

• WaterproofingPrevents leakage and protects the substructure from water damage

• Durability: Resistant to UV, ozone, aging, and heavy vehicular loads

• Temperature RangeSuitable for extreme temperatures (-40C to +80C)

• Installation: Can be installed in cast-in-situ or pre-cast concrete decks

Applications

• Highway and railway bridges

• Flyovers and elevated roadways

• Industrial and marine structures requiring expansion accommodation

Benefits

• Maintains smooth traffic flow and reduces noise and vibration

• Protects the bridge structure from water ingress and corrosion

• Minimizes maintenance costs and extends structural lifespan
