Technology for extending the lifespan of bridge structures! Measures against bridge aging and the increase in the size of passing vehicles!
The SEEE method for bridge reinforcement using external cables has been beneficial in extending the lifespan of many structures to compensate for insufficient load capacity due to increased traffic volume, larger vehicles, and deterioration of main girders. The "F-PH type" cable has high fatigue strength and is suitable for steel bridges with relatively large stress amplitudes. Produced in a prefabricated type under sufficient quality control in the factory, it eliminates the need for length measurement and anti-corrosion processing on-site, allowing for cost reduction. We also offer the standard cable "F-TS type," which has many proven results, including for concrete bridges. Our company handles many other products related to bridge structural projects. 【Features】 - No need for on-site length measurement or anti-corrosion processing, enabling cost reduction - Nut-type anchoring allows for an economical design without set quantities - Necessary prestress is reliably introduced even with short cables - Re-tensioning and replacement can be easily performed *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."
