At its first World of Concrete, steel wire rod mild producer KoSteel showed a new take on concrete reinforcement: Bundrex steel fibers, .75-mm (1/32-in.) diameter in 50- or 55-mm sizes (2- or 2.16-in.) with 67-mm (2.66-in.) and 73-mm (2.87-in.) aspect ratios, fabricated in a patent-pending arch design. The company credits the configuration with increasing fibers’ load-carrying capacity in concrete structures up to 20 percent over conventional end hook steel products.
