The product height is low! 75mm! Ideal expansion device for old bridges and thin slabs.
Hybrid Joint TS Type
The product height is low! Responding to the demand for low-height expansion devices! A thinness that fits within the typical pavement thickness: "Hybrid Joint TS Type."
【Feature 1】Low Product Height In recent years, in response to the increasing demand for low-height expansion devices, we have developed a unique product. This product, with a height of 75mm, fits within the typical pavement thickness and is particularly suitable for older bridges where there are restrictions on the thickness of the deck. Additionally, in snowy regions, products that can handle snow compaction have also been developed. Please feel free to reach out if you have any concerns. 【Feature 2】High Water Resistance The connection points between joints and the rubber and steel plate sections are bonded through press vulcanization, preventing delamination and providing excellent water resistance. 【Feature 3】Short Construction Time Due to the shallow notch depth, construction can be completed in a shorter time compared to conventional products. 【Feature 4】Design Tailored to Expansion Amount and Shape Designed and manufactured according to the expansion amount and shape for each location. It can be used in various situations, including connection points, ultra-small bridges, and pedestrian areas.

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.
