SUPER BUNDREX®
- BUNDREX®
-
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. - Online inquiries SPEC
