UPSET FORGING PARALLEL THREAD
As an important parallel thread connection technology, the upset forging parallel thread connection technology posses following advantage:
1.Wide working range: adaptable for Φ12mm-Φ40mm same diameter, different diameter,
bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706, ACI318,BS 8110, DIN 1045, standard.
2.High strength: stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of connection point =1.1 times of connected bar).It can satisfy the requirements stipulated in the Chinese standard JGJ107-2010,JG171-2005.
3.No reduction of the bar cross section area.
4.Allows full ductile elongation of bars.
5.Easy installation, no torque wrench required.
6.One standard coupler for all splicing requirements (Standard/Position).
7.Manufactured under strict quality assurance plan, ISO 9001 and ASME certified.
8.Full traceability of material origin and production batch.
9.Type 2 coupler suitable for seismic areas.
10.Tested under reverse-cyclic conditions.
11.Solves bar congestion problems.
12.No staggering of spliced bars required.

According to Chinese standard GB 1499.2-2007,
For rebar HRB400:Tensile strength≥540Mpa,Yeild strength≥400Mpa;
For rebar HRB500:Tensile strength≥630Mpa,Yeild strength≥500Mpa.
The upset forging parallel thread connection technology can not only be used for the connection of HRB400 rebar, but also for other rebar, such as HRB500, Gr.60, Gr.75, Gr.80, B500B,B500C, etc. Those of tensile strength is more than 700Mpa and so on.
3. Working principle
First, we use GD-150 to forging the end of rebar.
Second, we use the GZL-45 to threading the end of rebar.
Third, we use the coupler to link the two ends of rebar.
4. What makes us successful
A. Shorten your engineering period -- the two rebars can be connected within 35 seconds;
B. Catch the highest quality -- 100% broken rebars, no safty worrying, can past any safty quality test;
C. Save rebars -- give up weld and colligation rather than our connecting methods,
can save many rebars materials.
