クリテック工業 本社、大阪営業所、福岡営業所 Official site

The replacement work for the expansion joints on the Tomei Expressway (Yokohama section) has been successfully completed, and the completion inspection was finished on April 9, 2026. This project, which we undertook as the main contractor, is the largest scale project our company has ever handled (with a construction period of about one and a half years). Crittec Industries, as a manufacturer of expansion joints for bridges, handles everything from research, design, manufacturing, and sales to construction in a consistent manner. In this project, we leveraged our on-site adjustment capabilities, technical skills, and a network of multi-skilled personnel to achieve smooth construction. Furthermore, due to the trust and experience we have built up over the years with numerous construction achievements in the challenging infrastructure environment of the Tomei Expressway since our founding, we successfully completed this project as the main contractor. Our flagship product, the "Hybrid Joint," is characterized by long-term durability and high water-tightness, and it has been adopted in many bridges. We would like to express our deep gratitude to the client, Central Nippon Expressway Company Limited, our partner companies, and the local residents.

In the fiscal year 2026, various comprehensive construction materials and equipment information magazines have been newly published. In the "Construction Materials and Methods Yearbook" published by the Economic Research Association, our delivery and construction achievement photos have been featured on the cover. Inside, we introduce product information, including a 100-year durable expansion joint, as well as unit prices. Additionally, we have published information in the following industry magazines: ● Estimation Materials ● Estimation Materials Public Price Version ● Base Design Materials ● Materials and Methods Data Sheets ● Construction Methods NETIS By adopting our hybrid joints, the frequency of replacements is reduced due to long-term durability and high water-tightness, leading to lower life cycle costs. This contributes to the longevity of bridges and ultimately strengthens national resilience. We invite you to visit our page in the comprehensive construction materials and equipment information magazines and consider the adoption of hybrid joints.

This time, Crittec Industries has implemented changes to the product specifications and expanded the application conditions for the bridge expansion device "Hybrid Joint" in the "LL type (LL-125, LL-150, LL-175)." With this specification change, we have improved workability and made it possible to accommodate a wider slab gap than before. ■ Main Changes 1. Change in Anchor Rebar Arrangement To further enhance the structural stability of the product, we have optimized the arrangement of the anchor rebar. 2. Expansion of Applicable Slab Gaps By reviewing the design and structure, we have expanded the range of applicable slab gaps for each model. This increases flexibility in product selection during design and allows for adaptation to a wider range of bridge conditions. ■ Changes to Applicable Slab Gaps The numerical values for the applicable conditions (applicable slab gaps) before and after the changes for each model are as stated in the PDF of the release. ■ Future Developments With this specification change, the LL type has evolved into a product that can meet more severe conditions and diverse design needs. Our company will continue to promote technological development that contributes to the longevity of infrastructure.

Thank you very much for your exceptional support as always. As of April 1, 2026, the new fiscal year has begun. This year, we welcomed two new employees, marking a fresh start with an even more vibrant team. Under the fully bloomed cherry blossoms, all employees gathered for a commemorative photo to celebrate the start of the new fiscal year with our new colleagues. All of us are renewing our commitment to our work. Going forward, Crittec Industries will continue to strive to be a company that contributes to the longevity of bridges, focusing on improving our technical capabilities and ensuring quality. We appreciate your continued support and patronage this year as well.

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.

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.
