On February 26, 2026, an advertisement for the bridge expansion device "Hybrid Joint" was published in the Tohoku 6 Prefectures edition of the Sankei Shimbun, demonstrating a durability of 100 years (3LII type) verified by a third-party organization.
Crittec Industries Co., Ltd. published a newspaper advertisement (black and white, full-page 15 columns) for the bridge expansion device "Hybrid Joint" in the February 26, 2026 issue of the Sankei Shimbun Tohoku 6 Prefectures edition. In Japan, the number of bridges over 50 years old is rapidly increasing, making the longevity of bridges a critical issue. The expansion devices, which are considered a cause of bridge damage, require high water-tightness and long-term durability. Our expansion device "Hybrid Joint" offers multiple types tailored to different bridge types and conditions. Among them, the "Hybrid Joint 3LII type" has demonstrated a durability of 100 years in fatigue loading tests conducted by a third-party organization. It has successfully passed 12 million cycles of repeated loading at a maximum load of 260 kN, confirming performance equivalent to a 100-year design service life for bridges. We have numerous delivery records in the six Tohoku prefectures and can accommodate a wide range of bridge types, including steel and PC bridges. The special website linked to the advertisement allows for the review of detailed materials and inquiries or requests for documents. Please make use of it for comparing and considering bridge renewal and repair plans. Crittec Industries will continue to contribute to the longevity of bridges nationwide, starting with the Tohoku region.

Demonstrating market responsiveness. Completion of the installation of the dedicated expansion device "Hybrid Joint NCS-40" for Nagoya Expressway.
Crittec Industries completed the installation of the bridge expansion joint "Hybrid Joint NCS-40," designed specifically for steel deck bridges, for a project commissioned by the Nagoya Expressway Public Corporation in November 2025. In urban expressways, steel deck bridges are often adopted due to their lightweight and slim design. Unlike typical bridges that have a thick concrete deck beneath the pavement, steel deck bridges feature steel directly under the pavement. However, these bridges experience significant expansion and contraction due to temperature changes and traffic, necessitating high followability and durability at the joint sections. The NCS-40 incorporates improvements over conventional products as a new technology. Firstly, the shape of the rubber component responsible for expansion and contraction has been modified from the traditional V-shape to a more accommodating M-shape. This enhancement increases followability against forces perpendicular to the bridge axis, reducing the risk of rubber cutting. Additionally, its high flexibility helps to suppress the reaction force transmitted to the fixed bolts. The method of bonding the rubber to the steel deck uses a mold for integrated molding, improving water-tightness and durability. This product has passed the fatigue loading test (durability of over 15 years) set by the Nagoya Expressway Public Corporation. Currently, each technology is in the process of being registered as "new technology" certified by the corporation.

The replacement work of the expansion joints on the Tomei Expressway (Yokohama area) has been completed without any accidents. The large-scale project was successfully carried out with a consistent system and track record in investigation, design, manufacturing, sales, and construction.
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.
