    Product Advantages: Strict quality control.  self-inspection, exchange inspection, sample inspection , 100% inspection etc. reject rate lower than 0.6%. Tensile strength could reach 800 to 900Mpa. Normal steel,for example, HRB335,the tensile strength reaches 500.5Mpa is OK. Our rebar couplers are suitable for steels of different countries. Simple to operate. Customer's special demands are available.
