For BUNDREX® low carbon steel wire rod of high-quality made by Kosteel Co., Ltd. is used. In order to avoid manufacturing defective products from the beginning, we use low carbon steel wires produced through systematic processing management and strict quality inspection in accordance with ISO and KS product standards.
ㆍMaterial : ASTM A820, TYPE 1
ㆍTensile Strength : 700 ~ 1,200Mpa
ㆍHigh bond strength to concrete due to high shape factor
ㆍAppearance : END HOOK TYPE / BUNDLE TYPE
ㆍBUNDLE(Glued) TYPE spreads evenly without fiber ball
ㆍEND HOOK TYPE acts as an anchor inside concrete enhancing effects of crack control without ( with ) increased toughness and fatigue resistance
ㆍSpecific ation for domestic demand
