Crittec Industries, a manufacturer of expansion devices for bridges, received the "Chairman's Award of the Shinkin Central Bank" at the "2026 Shinkin Excellent Company Awards" held on March 16, 2026. This award is a system that selects outstanding companies from among the business partners of 23 Shinkin banks in Tokyo. Our company was nominated as a representative of approximately 20,000 business partners of Shiba Shinkin Bank and received the award after a rigorous screening process. The development of the bridge expansion device "Hybrid Joint Type 3LII," which achieves a durability of 100 years, was highly evaluated for its contribution to reducing maintenance costs through lower replacement frequency, as well as its role in mitigating social costs such as traffic regulations. Additionally, our social contribution activities, including the utilization of senior talent, promotion of health management, and the implementation of the experiential learning program "Crittec Academy" for elementary school students, were also comprehensively recognized. With this award as a catalyst, our company will strive for technological innovation and quality improvement aimed at realizing sustainable social infrastructure and creating further value.

Durability 100 years, expansion device, hybrid joint, type 3LII.
A bridge expansion device proven to last 100 years! No replacement needed for new bridges for 100 years! Long-term water-tightness, maintenance-free [NEXCO specification compliant product].

**Features** 1) Ultra-long durability of 100 years: Achieved 12 million cycles in fatigue loading tests by a third-party organization, proving a durability of 100 years. 2) Long-term water-tightness of 50 years: Proven water-tightness equivalent to 50 years through water-tightness performance tests by a third-party organization. Secondary water-stop materials are standard specifications. 3) Large expansion and contraction capacity and wide gap compatibility: One of the largest expansion capacities among NEXCO-approved products. Capable of accommodating expansion from 150mm to 350mm and maximum gap of 730mm. 4) Ultra-low noise and vibration-free: A vertical integrated structure with 32mm thick steel plates arranged vertically and alternately, making it difficult for air vibrations to transmit under the beams, thus reducing noise. Smooth and comfortable driving experience. Small wheel load support intervals make it less likely for impact vibrations to occur during driving. 5) Easy to install: Can be constructed without road closures, using lane restrictions that allow shared use of one side for both new installations and repairs. Lighter compared to conventional large products. 6) Maintenance-free: The load support plate and anchor plate have a vertical integrated structure with high durability. Additionally, the structure prevents damage from metal fatigue, allowing for visual maintenance management. Visual inspections are sufficient, eliminating the need for regulated sound inspections. 7) NETIS registered: This is a new technology registered in the Ministry of Land, Infrastructure, Transport and Tourism's database system "NETIS." Registration No. KT-210067-A.
