DYWIDAG-Systems International , also known as DSI, develops, produces and supplies post-tensioning systems to meet the exacting demands of global construction markets.
DYWIDAG and SUSPA post-tensioning systems are characterised by good load-carrying performance, durability and simple design. The post-tensioning systems ensure safe, efficient and economic use in pre-stressed concrete structures. DYWIDAG systems have good versatility and reliability.
DYWIDAG strand post-tensioning systems are used in bridges, buildings and dams around the world. As a result of DSI’s ability to vary the number of strands in its tendons, its systems offer a high degree of flexibility and can always be adapted to suit individual clients’ needs. DYWIDAG post-tensioning strands are ETAG 013 approved and authorised for cryogenic use including the construction of LNG- and LPG tanks.
Today, post-tensioning bars are primarily used for repair and strengthening projects.
