Construction Material Rebar Coupler

Straight thread sleeves are steel sleeves for steel joints that provide the axial tension or pressure of the reinforcing bars. The longitudinal and transverse ribs of the steel bars to be connected are stripped off by means of cutting and then directly rolled Into ordinary straight thread, with a special straight thread sleeve connected to form a reinforced connection. The connection technology is efficient, convenient and rapid, which can save energy, improve efficiency and provide stable connection.
