Rebar mechanical splice (Bartec^® and Griptec^®)

The Bartec^® rebar mechanical splice system consists in enlarging the reinforcing bar ends by cold-upsetting prior to threading them.  The bars are cut square before the enlarging operation.  The splice is formed by engaging the threaded ends of rebars into the threaded Bartec coupling sleeve.

The Griptec^® rebar mechanical splice system consists of threaded sleeves that are extruded onto the reinforcing bar ends.  A combination of male and female sleeves creates the connection.  Female sleeves are generally used on first-phase bars, in order to ease the closing of the formworks.  Male sleeves are generally used on continuation bars.
