1, High strength: The strength reach Grade I, 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 JGJ107-2003, JG171-2005

2, Wide working range: Adaptable for 12mm-50mm 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 efficiency: Upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.

4, Environmental protection and economy profit: No Environment pollution, can work all day, not affected by weather, economize energy source and bar material.
