Changsha DLADTO Rebar Splice Co., Ltd

Cold Extrusion Connection of Rebar Coupler is a new technology of rebar connection in the construction of reinforced concrete structures. At present, it is widely applied in many large-scale projects.   The advantages of cold extrusion rebar coupler are as follows: 1. The construction technology of  Cold Extrusion Rebar Coupler  is simple and easy to master. 2. Compared with the traditional welding method, the construction of Cold Pressing Rebar Coupler is fast, which can save a lot of time. 3. It can save construction costs and is relatively environmental-friendly. 4. The Cold Extrusion Rebar Coupler Technology can connect the diameter of steel bars from φ16-φ40.   ADTO is a professional manufacturer and exporter of rebar mechanical splicing products. Our main products include rolling parallel thread rebar coupler series; cold extrusion press coupler series;  Grouting rebar coupler   series; weldable rebar coupler series; special shaped coupler etc. All the products are factory direct

Class I   Rebar Connector There are two criteria for determining the level I joint: 1) The actual tensile strength of the reinforcing rebar connector must be greater than the standard strength of the reinforcing bar base material, and it must be broken from the reinforcing bar.  2) If the connecting piece damages but didn't broken the steel bar, the actual tensile strength value of the rebar connector must be bigger than 1.1 times the standard tensile strength value of the parent material, and it can be judged as qualified when reach or over 594Mpa. The standard tensile strength value of HRB400 steel bar is 540Mpa. Class II Rebar Connector Judgment standard for grade II rebar connector: No matter which place of the rebar connector is broken, as long as the actual tensile strength value of the steel bar connector exceeds the standard tensile strength value of the steel base material by 540Mpa, it can be judged as qualified. Class III Rebar Connector Judgment standard for grade III r

Mechanical splice  is superior in transfer loads because it creates a direct mechanical connection at the junction of two rebars, which looks like a naturally elongated rebar. In general, mechanical splice have the following advantages: 1. Improved structural integrity 2. Improved design options 3. Ideal balance of steel and concrete by reducing unnecessary use of rebar 4. Reduced crowding and weight of concrete structures. 5. Reduced the amount of carbon dioxide produced by construction 6. Reduced the cost of rebar Changsha DLADTO Rebar Splice Co., Ltd  is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world.

The difference between the grade I, II, III   rebar joint ： Different mechanical properties Grade I rebar joint: the tensile strength of rebar joint is greater than or equal to the actual tensile strength of the connected steel bar or 1.10 times the standard value of the steel bar tensile strength, and it has high ductility and repeated tensile and compressive properties; Grade II rebar joint: the tensile strength of rebar joint is not less than the standard value of the tensile strength of the connected steel bar, and it has high ductility and repeated tensile and compressive properties; Grade III rebar joint: the tensile strength of rebar joint is not less than 1.25 times the standard value of the yield strength of the connected steel bar, and it has certain ductility and repeated tensile and compressive properties. Different percentages of rebar joint The percentage of Class I rebar joint has no specified limits unless there are special requirements; The percentage of Class II rebar
