Rebar coupler

Join bars without overlapping

A rebar coupler is a mechanical splice that joins two steel bars end to end, with no lap overlap. It is widely used in columns and beams, and Freehold Construction & Development manufactures couplers locally and also offers on-site threading and forging.

Types of rebar couplers

Different locations in a structure need different splices. We supply the following common types.

Standard rebar coupler

Standard Rebar Coupler

A threaded sleeve that joins two bars of the same diameter in a straight line. The bar ends are threaded, the sleeve screws over both, and the joint carries load through the bar line without any lap length. It is the everyday coupler for continuous column and beam bars.

  • Same-diameter bars in line
  • Columns, beams and vertical bar continuity
  • Replaces lap splices and saves steel
Reducer coupler

Reducer Coupler

Joins two bars of different diameters. When the bar size changes from one floor or member to the next, a reducer coupler makes the transition in one joint, with no extra lap length or special detailing.

  • Different diameters on either side
  • Floor-to-floor column bar changes
  • Clean transition between members
Cold pressed coupler

Cold Pressed Coupler

A steel sleeve that is pressed onto the two bar ends with a hydraulic cold-press machine, so no threading or welding is needed. Both bar ends are inserted into the sleeve and aligned, then the machine presses it at 6 to 8 evenly spaced points. The joint is then checked for tightness, and any cracked sleeve is replaced. It is the practical choice when bars are already in place without threaded ends, for example when the lap length is not enough or the concrete has already been cast.

  • No threading or welding needed
  • Works on bars already placed in the structure
  • At least 100 mm of bar must be exposed (or exposed by breaking the concrete)
  • Available in 16, 20, 25 and 32 mm

Coupler or lap splice?

Lap spliceNeeds extra bar length for the overlap, adds steel weight and crowds the section. Not permitted for bars 36 mm and larger.
Rebar couplerNo overlap, so no extra steel. The section stays clear for concrete, and the joint is a defined mechanical connection.

Why use couplers

Less congestionFewer overlapping bars in columns and beams.
Less wastageNo lap length means less steel used.
Faster workSimpler bar fixing and quicker construction.
Higher integrityA defined mechanical joint instead of an overlap.
Easy extensionBars can be extended later for future floors.
Code compliantMeets BNBC 2020 and ACI 318-19.

When to use couplers

16 mm and aboveCost-effective, because lapping waste costs more than the coupler. Not cost-effective for 8, 10 or 12 mm bars.
36 mm and aboveLapping is not permitted. Couplers or welding are required.

On-site threading and forging

Besides supplying couplers, our team can thread and forge bar ends at your site, so bars are prepared to match your drawings and schedule.
