Shanghai Harex Steel Fiber Co.,Ltd.is now the largest steel filber producer in China.In terms of technical quality, its product fully conforms with the relevant standards.Harex fiber is a mill cut fiber of a new type.Because of its unique shape and high tensile strength,excellent bonding is ensured in concrete, hence remarkable strengthening effect, an increase of compression strength by 5-20%, an increase of flexural strength by 20-50%, an increase of tensile strength by 20-40%, an increase of crack resistance under impact load by 3-4 times and an increase of flexural fatigue strength by 1.65-2.25 times.It has advantages such as being low in dosage (min. 0.35%, normal range 0.4-0.8%), no balling during mixing and easy in placing.It is widely used in various concrete engineering projects both at home and abroad
