Coupler Information

Stressbar Steel Systems International, Inc. distributes couplers for all available bar sizes. Our bars are continuously threaded along their entire length and are easily coupled to eliminate the need for field lap spicing. Couplers are designed and manufactured to develop 125% of the published yield strength of the threaded bars.

With our clients in mind, SSSI can ship couplers pre-attached to threaded bars for ease of installation on site. Shipped in easy to handle bundles, our material can be picked up and placed by hand. The following images display projects utilizing our bars and couplers without steel templates. in this case, the "loose" bars with pre-attached couplers were installed individually from the story below.

Installation Procedure Grade 80 + 97 Couplers

  • Mark each bar to be coupled with tape or paint at a distance of half the length of the coupler from bar ends.
  • Fully thread the coupler onto one bar.
  • Align the adjacent bar with the bar containing the coupler.
  • Spin the coupler over the adjacent bar until half of the coupler engages each bar to expose markings on both bars.
  • Align the adjacent bar with the bar containing the coupler.
  • Wrench tight the upper bars to cut slack and secure couplers.
