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.
The product height is low! Responding to the demand for low-height expansion devices! A thinness that fits within the typical pavement thickness: "Hybrid Joint TS Type."
