Bridge expansion joint rubber strips are specially designed for various models of bridge expansion joints, with specifications and models produced in accordance with the Ministry of Transportation and Ministry of Railways standards. They can be matched with C-type, F-type, and E-type joints as well as other models of expansion joints. Rubber expansion joints utilize the high elasticity of rubber to adapt to the expansion and contraction deformation of the bridge surface due to temperature changes. They are praised by the bridge engineering industry for their ease of installation, smooth driving, waterproofing, dust-proofing, low noise, light weight, and low cost.

NR and CR denote rubber types: NR stands for Natural Rubber, CR for Chloroprene Rubber. Application Scope:

1. Expansion joint devices using chloroprene rubber (CR) are suitable for regions with temperatures ranging from -25 to +60 degrees.

2. Expansion joints using natural rubber (NR) are suitable for temperatures ranging from -40 to +60 degrees.
