Buildings and Structures Concrete Reinforcement

Rebar Connection, Anchorage and Termination Solutions For Towers, High-Rises and Skyscrapers

Structural engineers and contractors across the world trust nVent LENTON couplers for solving rebar splicing, anchorage and termination challenges in commercial buildings and industrial structures of all types. We are rebar attachment experts that can provide you with excellent mechanical connections for your next concrete reinforcement project.

A Better Way


The traditional method of connecting concrete reinforcing bars in high-rises, skyscrapers and towers has been lap splicing. But as many architects and specifiers have discovered, lap splicing does not provide the same advantages as mechanical splicing in the reinforced concrete construction process.

We bring you the world’s most widely used threaded splices that create a positive locking connection and provide structural integrity to reinforced concrete slabs, beams and other building foundational elements. nVent LENTON spliced bars behave as continuous lengths of reinforcing steel bars by providing “full strength” in tension, compression and stress reversal applications to improve constructability and efficiency in major projects.

For construction business owners, the difference often comes down to time saved and money spent.

Lap vs. Mechanical Splices


The benefits add up when you choose mechanical splicing connections for building reinforced concrete structures.

Solar Farm

Lap Splices:

  • Tend to have poor cyclic performance. To prevent concrete splitting, additional rebar may be required for confinement.
  • Present design constraints. Lap splices double the number of bars leading to rebar congestion which can restrict the flow of aggregates.
  • Have hidden costs. Lap splicing can involve time-consuming calculations and overestimating mistakes.
Additive Facility

Mechanical Splices:

  • Are proven to be reliable. Mechanical splices behave similar to a continuous piece of rebar and offer superior cyclic performance.
  • Are design friendly. Reducing rebar congestion and improving concrete consolidation are easier with mechanical splices.
  • Are economical. Mechanical splices require no special skills and reduce labor and material costs because less rebar is used.

Product Portfolio


Find the best code-compliant solutions for the job with nVent LENTON.

  • Precast splicing systems that provide strength between load bearing precast concrete elements such as columns, beams, shear walls and panels.
  • Metal-filled splicing systems that produce a joint with essentially the same mechanical properties as those of an unspliced bar, suitable for in situ applications.
  • Quick wedge splicing systems that are a simple and fast alternative for joining small diameter reinforcing steel bars.
  • Shear bolt splicing systems that require no rebar end preparation and are ideal for new construction, repair or retrofit applications.
  • Form savers that are ideal for eliminating protruding dowel bars in segmental pour applications while protecting valuable forms from damage.
  • Speed sleeves for compression-only steel reinforcement applications.
  • More from the world-leader in mechanical splicing for reinforcing bars
