Summarizing and introducing the merits and demerits! Clearly distinguishing the differences from other devices.
Rubber joints are one type of expansion device, primarily made from rubber and sealing materials. Basically, the device itself cannot support the weight of a vehicle, so it is often installed in places like sidewalks or areas with low traffic. However, rubber materials are easy to maintain after installation and have the characteristic of reducing the impact on vehicles passing over them. Therefore, it is common for expansion devices to be made not just from rubber alone, but in combination with steel materials. *For more detailed information, please refer to the related links.

Company information
CRETEC, a company under Crittec Industries, was born from the combination of Create (creation) and Technology. As a comprehensive manufacturer of bridge expansion devices, we continue to develop expansion devices that contribute to the longevity of bridges and environmental protection. Moreover, we do not stop at product manufacturing; by consistently handling everything from research, design, manufacturing, sales, to construction in-house, we can manufacture and install expansion devices that meet the requests of our clients and general contractors, as well as the conditions and environments of the bridges and roads on-site. We also take into account the issues that arise during the installation of expansion devices and the damage conditions of existing devices that are removed, using this information to improve and develop our products. Please feel free to contact us for inquiries about bridge expansion devices, requests for materials, or estimates. ◆ What is a bridge expansion device? It is a component installed in the gap between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create a gap to prevent the bridge girders from colliding due to expansion and contraction caused by temperature changes. The bridge expansion device is required to cover this gap and ensure safe passage for vehicles and pedestrians.
