Rebar couplers are components which connect two reinforcing bars in longitudinal direction, forming a mechanical splice. This is an alternative to lap splices or welded connections.

Mechanical splices are used to avoid protruding bars in casting joints, reduce congestion in confined spaces and to save rebar length.

Rebar couplers are manufactured and attached to the rebar with different technologies and have therefore different characteristics, such as tensile capacity, robustness under real site conditions, the ease of the assembly and control of the correct installation. It is important to consider these characteristics to make the right choice for your project.
