Rebar Coupler Connection
1.Material:carbon steel
2.Easy operation
3.Saving time and rebar materials
4. NO.45 steel

Factory Price!!!steel bar/rebar/carbon steel connecting sleeve, straight screw sleeve  coupler connection/joint

 

A new way for rebar mechnical connection with high quality and efficiency.

1. Easy Operation, saving time and rebar material. The rebar coupler producing and rebar end threading will not be affected by the weather; It can be processed before processing.

2. It can connect the rebar with the diameter 14mm to 40mm.

3. Use No. 45 steel, with the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part

 

 

Reinforced mechanical connection technology is a new type of steel bar connection technology, called the tie, welding after the "third generation reinforced joint", has the joint strength is higher than steel cold extrusion reinforced metal base, faster than welding fast 5 times, no pollution, save steel 20% etc.

 

 

Rolling straight thread joint characteristics

 

1. Don't weaken the parent metal, joint strength high, After the connection of joint can meet Chinese standard (JGJ107), American standard (UBC1997), British standard (BS8110), German standard (DIN1045), ISO/WD15835 (draft), and other relevant standards at home and abroad.

 

2. The process is simple, does not need professional technicians, stable quality easy control, high production efficiency,

 

3. Field connection speed, quality easy examination.

 

4. The equipment operation is simple and flexible, small power consumption, low cost.

 

5. Economic environmental protection, security, not affected by climate and environmental impact.

 

 

Sleeve quality requirements

 

1,Connection surface of no crack, screw tooth full, without other defects

 

2,Tooth type specification inspection qualified, with straight thread plug check size accuracy.

 

3,Various type and specification of the connection of the outside surface, must have obvious reinforced level and diameter.

 

4,Connect the two end of hole must use the plastic cover sealing to keep internal clean, clean rust.

 

 

 

 

 

Simple construction process: will be reinforced at the end of the rolling process with a straight thread, and the corresponding connection sleeve reinforced two connected to each other.
