Bridge collapse prevention device based on the road bridge specification! Connecting cables with durability, cushioning, and flexibility.
The "F-TD type" is a bridge collapse prevention device using connecting cables. It ensures the movement amount based on the "Guidelines for Road Bridges" (March 2012: Japan Road Association), mitigates the impact of seismic forces, and allows for following in the direction perpendicular to the bridge axis. The connecting cables are completely double anti-corrosion PC cables, with multiple strands of PC steel wire coated with anti-rust oil and polyethylene. Additionally, the springs are conical coil springs that secure the large movement expected during an earthquake. Our company also handles many other products related to bridge structure projects. 【Features】 - Adopts the anchoring method specified in the "PC Method Design and Construction Guidelines" by the Japan Society of Civil Engineers - The connecting cables are flexible and safe, ensuring reliable PC cables - The section of the apartment part considers rust allowance - Has extensive usage records in various fields for anti-corrosion cables - Rust prevention treatment using metal spraying is possible for the apartment screw parts *For more details, please refer to the PDF materials or feel free to contact us.

Company information
In 1967, SE Corporation introduced the SEEE method domestically from the French company S.E.E.E. (now ingérop) and was established. Forty years have passed since our founding, and along with the times, not only have our technologies and methods changed rapidly and significantly, but the business environment surrounding us has also transformed. However, our fundamental stance of "aiming for a rich social environment and harmony with nature while continuously providing new value" remains our unwavering foundation. Moving forward, we will actively contribute to society by providing world-class technology and systems to revitalize the development of social infrastructure, which is the foundation for protecting people's lives and property, and we will continue to challenge ourselves as a united group aiming to become a "global engineering manufacturer."
