BUNDREX® refers to steel processed into fibers with a small cross section and short length. It is a concrete reinforcement material that compensates for the physical shortcomings of existing concrete by being dispersed in three dimensions into concrete.
KOSTEEL’s world-patented steel fiber for concrete reinforcement named BUNDREX® is produced through Korea’s state of the art high-tech process. It is an ideal concrete reinforcement material that addresses the problem of the brittle fracture characteristics of concrete by creating ductile fracture characteristics and flexural toughness while preventing plastic shrinkage and drying shrinkage cracking.
 World's first arched patented product Scientific improvement for a breakthrough innovation in SFRC structural stability This is the first arch-shaped patented product in Korea. |
 Concrete reinforcement with outstanding performance By improving the adhesion strength and bending performance of concrete, cracks are reduced, and the thickness of concrete can be reduced. |
 Excellent economics through cost reduction Reduce material costs! Save on equipment costs! Shorten construction time! By casting directly from the ready-mix concrete vehicle without additional reinforcement work, construction cost can be reduced by 40% |
