Rebar coupler types

Rebar Coupler Types

Rebar couplers are mechanical or welded devices used to join reinforcing bars in concrete structures. They replace or reduce lap splices, improve continuity, and support faster construction where rebar congestion or limited development length makes overlapping difficult. Different rebar coupler types are selected based on bar grade and diameter, site constraints, installation tools, inspection needs, and whether the splice must work in tension, compression, seismic zones, or restricted positions. Below is a clear overview of the most common types of rebar couplers used on modern jobsites, along with practical guidance for choosing the right solution.

Working Principle & Process Flow

Each coupler type uses a different method to transfer forces from one bar to another. Threaded systems rely on precise bar-end threading so the coupler can engage like a nut and bolt. Taper-thread systems use tapered profiles that self-tighten under load. MBT and shear bolt couplers clamp the rebar using hardened bolts and internal grip rails, delivering quick installation without threading. Grouted and swaged systems use grout or deformation to lock the bar inside a sleeve. Welded couplers create a metallurgical bond where allowed by code and site procedures. The right process flow depends on whether bar-end preparation can be done in advance, and whether field installation must be fast with minimal equipment.
