High Quality Parallel Thread Connecting Steel Rebar Splicing Coupler

we has passed the ISO9001 certification every year, and has reached international standards in the integration of various management systems. It can continue to provide customers with expected and satisfactory qualified products.

Our products have 7 invention patents, more than 20 practical new patent certificates, and 1 appearance design patent

Our couplers can meet the tensile strength requirements of HRB400 and HRB500. According to experimental testing, the minimum insertion length of the reinforcement can be reduced from the lowest 8x reinforced diameter to 6 times the diameter of the reinforcement performance.

The ends of the product are designed to ensure that the steel bars connecting the grouting test parts can be tightened, increasing the resistance of the test parts, and improving the quality of tensile resistance. The original need for 28 days and the qualifying rate of 90%of the tensile strength test. It only takes 10 days to complete the corresponding test, and the pass rate reaches 100%. The improvement of tensile strength can effectively save the production cycle and reduce energy consumption.

Our product wall thickness area strictly follows the "Standards for the Construction Industry Industry Industry of the People's Republic of China" JG/T163-2013 The cross-sectional area of the reinforced mechanical connection of the reinforcement machinery connection. The industry standards of JG/T398-2019 are used for steel bars.
