Upset forging parallel thread coupler(black surface,white surface,light surface)


Upset forging parallel thread coupler is the best quality rebar connection in the world. With the connection quality that the strength is 100% higher than bar material,many standards in the world set this kind of connection as the highest Grade I connection specification. The upset forging parallel thread connection originated from a French company who is the world's first developer of rebar connections. For this world recoganized Grade I connection, it is widely used in world's highest quality projects, such as the world's tallest building Burj Khalifa, the world's longest sea-crossing bridge Jiaozhou Bay Sea-Crossing Bridge. With advantages of high quality, fast connecting speed, competitive price, it firmly occupy the whole area of rebar mechanical connector.



Meet Chinese standard(JGJ107), American standard(ACI318, ACI349), British standard(BS8110), French standard(NF35-20-1), Germany standard(DIN 1045), ISO15835 and many other relevant domestic and foreign standards;


Comparison between upset forging parallel thread connection and rib peeling roll stamping connection. The picture in left is the cross section area of upset forging parallel thread connection after processing thread, the picture in right is the cross section area of upset forging parallel thread connection after processing thread. The left cross section area is apparently larger than the right one, moreover, molecular structure is tighter and hardness is better in rebar thread part of upset forging connection.



I.Upset forging parallel thread coupler,standard sizes:

12mm,14mm,16mm,18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm, 50mm, including client's customized sizes, such as European countries customized 24mm, 34mm, 38mm, Korea customized 19mm, etc.. All coupler dimensions and inner thread can be customized. Moreover, we can also calculate coupler dimension and material according to client's rebar strength and international standards of after rebar connected.

 

1.black surface coupler,it is quite popular among international clients. Advantages are as below:

1)the coupler surface is oxide layer during production process, it forms a protective layer on coupler surface, with better anti-rust effect than white surface.

2)oxide layer destroys coupler surface, therefore it improves coupler flexibility and elongation in mechanics

3)oxide layer can fix with concrete more strongly


Coupler strength can meet Chinese standard(JGJ107), American standard(ACI318, ACI349), British standard(BS8110), French standard(NF35-20-1), Germany standard(DIN 1045), ISO15835 and many other relevant domestic and foreign standards;

Coupler strength can reach 630MPa, 750MPa, 800MPa, 950MPa, 1050MPa, it is adjustable according to client's different requirements.  

2.white surface coupler, it is produced by processing outer surface on coupler material according to client's requests.The advantage is that it makes the apperance looks more beautiful, but it will decrease the mechanical strength, and the anti-rust capability is lower than black one.

the standard sizes are:

12mm,14mm,16mm,18mm,20mm,22mm,25mm,28mm,32mm,36mm,40mm,50mm, including client's customized sizes. All coupler dimensions and inner thread can be customized. Moreover, we can also calculate coupler dimension and material according to client's rebar strength and international standards of after rebar connected.


Coupler strength can meet Chinese standard(JGJ107), American standard(ACI318, ACI349), British standard(BS8110), French standard(NF35-20-1), Germany standard(DIN 1045), ISO15835 and many other relevant domestic and foreign standards;

Coupler strength can reach 630MPa, 750MPa, 800MPa, 950MPa, 1050MPa, it is adjustable according to client's different requirements.



3.big chamfering coupler, the production requirements of this type is very high. Especially big chamfering processing, it must be processed by CNC production line, 100% comply with European standard of rebar coupler production。

rebar coupler sizes are12mm,14mm,16mm,18mm,19mm,20mm,22mm,24mm,25mm,32mm,34mm,36mm,40mm


Coupler strength can meet Chinese standard(JGJ107), American standard(ACI318, ACI349), British standard(BS8110), French standard(NF35-20-1), Germany standard(DIN 1045), ISO15835 and many other relevant domestic and foreign standards;

Coupler strength can reach 630MPa, 750MPa, 800MPa, 950MPa, 1050MPa, it is adjustable according to client's different requirements.
