Notice regarding product prices and delivery dates
We would like to express our sincere gratitude for your continued support. As you may be aware from recent news reports, the situation in the Middle East has deteriorated rapidly, leading to an increase in the prices of raw materials originating from that region. Consequently, there is a possibility that the prices of our products may also rise in the future. Please be advised that due to fluctuations in the market conditions of raw materials, we may change prices without prior notice, and we appreciate your understanding in advance. Additionally, regarding product delivery times, we are currently operating as usual. Should there be any changes in the future due to the situation, we will inform you accordingly. We apologize for any inconvenience this may cause and thank you for your understanding.

Ten years since the Kumamoto earthquake - The "Hybrid Joint LL Type" expansion device adopted for the new Aso Ohashi Bridge, designed to accommodate fault displacement.
The main shock of the Kumamoto earthquake that occurred in the early hours of April 16, 2016, caused the Aso Ohashi Bridge to collapse, significantly impacting local transportation. Following recovery efforts, the New Aso Ohashi Bridge was opened in 2021. In the New Aso Ohashi Bridge, structures that can accommodate future fault displacements have been incorporated, such as the use of a steel simple box girder bridge over the fault. Additionally, the expansion joints installed at the bridge's seams are designed to follow fault displacements. Our bridge expansion joint, the "Hybrid Joint LL Type," has been adopted for this New Aso Ohashi Bridge, contributing to the safety and functionality of the bridge while accommodating large displacements. Japan is a country prone to earthquakes, and bridge design requires ensuring safety against Level 1 seismic motion (earthquakes occurring during the service period) and Level 2 seismic motion (maximum class earthquakes). Moving forward, our company will continue to provide technologies that support the safety and security of social infrastructure.

The stretch device "Hybrid Joint," which combines rubber technology and metal technology, has high water resistance and a durability of 50 years! The 3LII type has proven a durability of 100 years!
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.
