Explanation of the differences and devices for enhancement! I have also summarized the mechanisms for enhancing the functions of the devices.
The expansion and contraction devices can be broadly divided into drainage type and non-drainage type. When these devices first started being installed, the drainage type was used, but over time, the non-drainage type has become the mainstream. The difference between the two lies in whether or not water leakage measures are implemented. However, due to the infrastructure development policies set by the government, most manufacturers have started producing non-drainage types. This article introduces the differences between drainage and non-drainage types as well as their usage ratios. Additionally, we have summarized the mechanisms that enhance the functions of the devices, so please refer to that as well. *For detailed content of the column, you can view it through 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.
