[NETIS Registered Product] A bridge expansion device with high water stop performance, comfortable driving, and ultra-low noise.
This is a bridge expansion device adopted nationwide, primarily by the Ministry of Land, Infrastructure, Transport and Tourism, NEXCO, urban expressways, local governments, and other public organizations. 【Features (excerpt)】 ◆ Compatible with small to large bridges Handles expansion amounts from 20mm to 600mm, with a maximum gap of 1230mm. Other specifications can be designed separately. ◆ Usable for all types of bridges Can be used for all types of bridges, including steel bridges, PC bridges, RC bridges, as well as arch bridges and curved bridges. ◆ High water-tightness "NS-LL type": The steel plate and sealing rubber are bonded using a mold (press vulcanization bonding), preventing separation between the steel plate and rubber. ◆ Safe and easy installation Can be installed using a 4-ton unic crane without the need for large machinery like medium to large rough terrain cranes, allowing for safe and easy (speed-up) construction. Here’s a brief introduction to some installation examples! ~~ At the Tochigi Prefecture Nikko Civil Engineering Office (Maruyama Bridge), a "Hybrid Joint" was used for renovation work. * NS-LL type repair ~~ At the Kinki Regional Development Bureau Kinokawa River National Road Office (Takasegawa Bridge), it was used for a newly constructed bridge. * 3L type For more details, please contact us or download the 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.
