LENTON® Weldable Couplers

LENTON® Weldable CouplersPrint this page

LENTON Weldable Couplers are designed for connecting reinforcing bar to structural steel sections or plates.

Features

  • Unique self-aligning taper-threaded design provides continuity and structural integrity
  • Spliced bars behave as continuous lengths of reinforcing steel bars by providing full strength in tension, compression and stress reversal applications
  • Designed to withstand man-made blasts, and other seismic events
  • Quick and easy to install
  • Develops higher tensile strength than lap splicing
  • Provides full load transfer with the slimmest and shortest coupler possible

Applications

Designed for connecting reinforcing bar to structural steel sections or plates.

More Information

Similar to the standard coupler, the weldable (or half) coupler is internally taper threaded on one end, with the other end prepared for welding. These couplers are machined from weldable grades of material such as A.I.S.I. 1018, 1030, 1035 or St52.3 depending on rebar size. The couplers are usually arc welded to the structural steel in a fabricating shop. The design of the weld, the selection of electrode, and other relevant choices depend on the chemical and physical properties of the structural steel to which the couplers are welded.
