By installing the guide board, it prevents damage to the main body by the grader in snowy areas.
The Hybrid Joint CF type features a tooth-shaped design that smoothly transmits the movement of wheel loads on its surface, and its structure is designed to minimize noise and vibration by absorbing shocks from unevenness. The water-stopping structure, made of elastic sealing material and rubber, offers high water resistance, and since standard products are assembled and delivered at the factory for installation, the likelihood of water leakage from connection points is low. 【Features】 ○ High water resistance ○ Low noise for comfortable driving ○ Complies with NEXCO standards For more details, please contact us or request a catalog.

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.
