Threaded rebar coupler is used for Mechanical Bar Splicing(14mm-40mm) in construction with high strength. Basic Information of Threaded Rebar Coupler 1.Size: 14mm-40mm. 2.Raw Material:45# high-quality carbon structural steel. 3.Type: Standard Type, Left-Handed&Right-Handed Type, Reducing Type. 4.Tensile strength could reach 110% of parent material. 5.Suitable Rebar: HRB335,HRB400,HRB500 and Equivalent Rebars. Relate Test of Threaded Rebar Coupler: 1.Tensile Strength=1.1*Tensile Strength of Rebar (Usually more than 600Mpa) 2.Fatigue Test: After 2 million times of fatigue strength test, connection is in good condition Product Advantages of Threaded Rebar Coupler: The raw material is 45# high-quality carbon structural steel. 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. We could pack the goods according to customer's special request. Simple to operate. |
