The "JG/T 163-2013 Steel Rebar Mechanical Coupler" specifically stipulates the minimum size parameters for rolling straight threaded rebar couplers, steel column coarse straight thread couplers, and steel straight thread couplers. Any steel rebar straight thread coupler with a size below the minimum size table of the national industry standard JG/T163-2013 for rebar connection is considered a non-standard steel rebar straight thread coupler. Conversely, any steel rebar straight thread coupler meeting or exceeding the requirements of the national industry standard JG/T163-2013 is considered a standard steel rebar straight thread coupler. The qualified standards for rebar coupler are as follows: 1. Coupler are made of international grade 45 steel, with special manufacturing processes ensuring high dimensional accuracy and reliable quality. 2. Capable of connecting HRB335 grade and HRB400 grade ribbed steel rebars ranging from Ф16 to Ф40mm. 3. After testing by the National Ce...
