parallel thread rebar splicing coupler

rebar coupler 1. It has high connecting intension and stable and reliable connecting quality. The intension of the connection has reached the requirement ofgrade connecting capacity in the Common Regulation of Reinforcing Bar Mechanic Connection. The tensile strength of connector should equal to or not less then 1.10 times of reinforcing bar actual standard tensile strength. 2. It has good endurance resistance and the connector has passed the two million times- Fatigue Tests of industry provision. 3. Saving materials: take the example of 40mm splicing coupler, extrusion sleeves is 4kg, the straight screw thread coupling sleeves in only 1.1kg. The weight of straight screw thread takes 25% of extrusion sleeves but the connector capability is the same as the extrusion sleeves. 4. Easy operation and high speed connection, the processing of the reinforcing bar end is factory operation, it wont occupy the time of construction, the local connection can save a lot of time. 5. The reinforcing bar connecting end processing is very simple. It can complete the rib peeling, rolling and stamping in one time loading. It has high speed processing and high precision of straight screw thread molding. Customer's special demand is available. 6. Wide application, it has no request of reinforcing bar solderability and can be used in the every orientation connection of same and different diameter reinforcing bar of HRB335, HRB400. 7. Environmental construction: The processing of the reinforcing bar and the site operation is safe and reliable without noise, open flame and soot. 8. Energy conservation: the capacity is only 3-4kw; do not need special switching equipment and special wire. 9. Good low temperature resistance Passed the -40oC low temperature test.10. All-weather construction: sacred from the wind, rain, snow and other weather conditions
