  Rebar coupler   are divided into parallel threading rebar coupler, cold extrusion rebar coupler, upsetting forged rebar coupler, split rebar coupler, grouting rebar coupler, etc. Regardless of the type of rebar coupler, they are named by the size of the steel bar it is connected to. At present, the specifications of the rebar coupler are 12, 14, 16, 18, 20, 22, 25, 25, 32, 36, 40, 50, and there are also positive and negative wires and reducer rebar coupler, such as: 25 positive and negative wires, 28 positive and negative wire, 28/25 reducing rebar coupler, 28/22 reducing rebar coupler, etc. The common specifications of the steel connecting sleeves produced are Φ12, Φ14, Φ16, Φ18, Φ20, Φ22, Φ25, Φ28, Φ32, Φ36, Φ40. the size can be customized as required.

Every product has its advantages and disadvantages, this has the actual performance in all walks of life. So how to choose mainly depends on the actual needs of the individual and psychological choice, of course, and the customer's own ability to choose. Straight Threaded Couplers are also different in size and standard according to different project requirements. Today we will tell you the key points of buying a  straight rebar coupler  for you to verify: 1. The inspection shall be carried out by random sampling of quality inspectors, 5% of each batch shall be randomly inspected, and the pass rate of sampling inspection shall be greater than 95%. When the rate of qualified products is less than 95%, the same quantity shall be selected for reinspection. When the average pass rate of the two sampling inspections is not less than 95%, the batch shall be judged qualified. If the qualified product rate is still less than 95%, the batch of rebar couplers should be inspected one by...

  The first B is the processing technology (rib rolling type straight thread sleeve) The second B is the standard type of coupler(if it is F, means it is the positive and negative type coupler; if it is Y, it is the different-diameter type coupler, which is usually called the variable-diameter type and they are listed on page 5 of the JG/T 163-2013 national industry standard) "4" is HRB400/HRB400E hot rolled ribbed steel bar. "25" is the steel bar model. GLUS refers to the manufacturer's unique logo or trademark. 2007 refers to the batch number of the current batch of sockets (it changed annually or quarterly) 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.

Quality requirements for   reinforcement joint sleeve : ① There are no cracks on the surface of the connecting sleeve, the threads are full and there are no other defects. ② If the profile specification is qualified, check the dimensional accuracy with a straight thread plug gauge. ③ There type and specification such as steel grades, diameter of connecting sleeve must be marked on the surface of it.  ④ The holes at both ends of the connecting sleeve must be sealed with plastic caps to keep the interior clean to protect it from rust-proof. 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. If you have any inquiry, welcome to contact us.

Marking method The mark of the  rebar coupler  have four parts: name code, type code, parameter (strength level of rebar) code, parameter (nominal diameter of rebar) code, etc. Name code: D is for upsetting straight thread, B is for rib rolling, G is for direct rolling, Z is for taper thread, J is for extrusion. Type code: standard type is B, different diameter type is Y, positive and negative wire type is F, flared type is K Main parameter (standard value of steel yield strength) code: ≤400 is 4, and ≤500 is 5 Main parameters (nominal diameter of rebar in mm) code: 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 50 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.

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 th...

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 ...
