[Column] What is an expansion device? Explaining its role in bridges and highways.
We are explaining what role the expansion and contraction device plays!
An expansion joint is a device used to fill the gaps found in bridges and highways. If there are gaps in a bridge, it can cause issues when vehicles pass over it, so these joints are installed to cover the gaps and allow for a comfortable passage. However, although they are referred to as coverings, they are not simply metal plates that cover the gaps. There are other roles that an expansion joint is required to fulfill, and manufacturers produce and handle products that meet the necessary quality and functionality. This article explains the roles that expansion joints play. It also summarizes the types of expansion joints and manufacturers, so by reading it, you should gain a general understanding of the topic. *For 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.
