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.
1, adopts upset forging parallel thread connection technology;
2, wide working range: Adaptable for 12mm-40mm same diameter, different diameter, bending, new and old, advance covered up rebar of GB 1499, bs 4449, ASTM a615 or ASTM a706 standard.
3, 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's specified tensile strength). It can satisfy the requirements stipulated in the Chinese standard jgj107-2003, jg171-2005.
4, high efficiency: Upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.
5, Environmental protection and economy profit: No envirement pullution, can work all day, not affected by weather, economize energy source and bar material.
