Transportation Infrastructure Concrete Reinforcement

Rebar Connection, Anchorage and Termination Solutions for Bridges and Tunnels

We offer products that adapt to changing construction environments to meet your concrete reinforcement needs for all types of transportation infrastructure. From bridges to tunnels to supporting constructs, we help customers boost the strength of superstructures and maximize every dollar spent on materials.

A Better Way


nVent LENTON products are used on bridges and tunnels across the world to connect, anchor and terminate rebar in precast and cast-in-place concrete forms. We are rebar attachment specialists that know the advantages a mechanical connection affords your rebar connection project.

Our products integrate into complex and challenging jobs just as easily as in simpler, less demanding ones. Find rebar splicing systems, couplers and more for pile cage, beam, column and roof-slab applications in tunnels as well as for deck slabs and tie-down piers on bridges. Lap splicing has been the traditional method of connecting concrete reinforcing bars; however, mechanical splicing offers distinct advantages that can save you time and money.

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


We offer a wide range of mechanical splices for almost any construction need:

  • 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.
  • Shear bolt splicing systems that require no rebar end preparation and are ideal for new construction, repair or retrofit applications.
  • Position couplers designed to splice bars where the ongoing bar is restricted in its axial movement or cannot be rotated, and length adjustability of the coupler is required.
  • Form savers that are ideal for eliminating protruding dowel bars in segmental pour applications while protecting valuable forms from damage.
  • More from the world leader in mechanical splicing for reinforcing bars.
