Nuclear and Rail Station Concrete Reinforcement

Rebar connection, termination and anchorage solutions for nuclear power, railway and subway station construction

The complete nVent LENTON product portfolio delivers a cost-effective option and a dramatic increase in the design flexibility of precast and cast-in-place concrete elements. Our expertise in connecting, anchoring and terminating concrete reinforcing bars spans decades and includes a deep understanding of critical infrastructure needs for nuclear power, railway and subway station construction.

Tap into an expansive portfolio of solutions for your concrete reinforcement project―nVent LENTON products are used in nuclear plant superstructures and railroad infrastructure across the world.

A Better Way


Our mechanical splicing technology uses threaded connections and has become the preferred method for connecting rebar for many customers due to the efficiency in providing load path continuity through reinforcing bar, as well as the steel savings that result due to the elimination of overlap in bars.

We are deeply knowledgeable about nuclear power and processing plant construction methods and can connect you to more options to save on labor and materials when building concrete reinforced structures for railways and subways.

Lap vs. Mechanical Splices


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 reliable. Mechanical splices behave similarly 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.
