It is a post-tensioning method for prestressed concrete anchoring construction.
The KTB anchoring method is a post-tensioning type of prestressed concrete anchoring technique applicable to all PC structures, encompassing a system that includes the basic anchoring body, PC steel strands, connectors, and more. The KTB anchoring method is adopted in a wide range of civil engineering and construction fields, such as PC bridges, building structures, PC tanks, marine structures, and ground anchors, due to its excellent workability, safety, high quality, and cost-effectiveness. In April 1978, the KTB Association was established to promote the dissemination, technological advancement, and development of this method. Additionally, SC strands (epoxy-coated PC steel strands) are ultra-durable PC steel strands with groundbreaking anti-corrosion technology, having obtained construction technology certification from the Civil Engineering Research Center in April 1995 (Chairman: Naoharu Ikeda, Professor at Yokohama National University). Thus, we take pride in confidently recommending the KTB anchoring method and SC strands as technologies that meet the needs of a new era. For more details, please contact us or refer to our catalog.
