URS Run Starts

This product's information may differ depending on the category of use. You are currently viewing details related to URS Run Starts. You can also view product information related to the category: ATS Run Starts

The rod-to-steel-beam connector (ATS-SBC) features a preattached high-strength steel threaded rod and weldable plate for use on projects where the run is to be anchored to steel beams. The SBC is pre-assembled as a single unit, saving contractors installation time and cost. The design of the steel beam and the stiffeners are the responsibility of the designer.

  1. Allowable loads are for ATS-SBC only. No further increase in allowable load is permitted.
  2. The weld length for the ATS-SBC5H and ATS-SBC6H requires only two opposing sides of the plate to be fillet welded full length less a 1/4" holdback from each of the edges. For the ATS-SBC8H up to the ATS-SBC12H, all four sides must be fillet welded full length less a 1/4" holdback from each of the edges. All fillet welds, FEXX, to be greater than or equal to 70 ksi and to follow geometry and standards per AISC 360-16 and AWS 2017. Prepare base materials in accordance with AWS D1.1.
  3. For purposes of coupling on to the rod above, the ATS-SBC threaded rod specification is UNC Class 2A, in accordance with ANSE/ASME B1.1
  4. The minimum tensile strength, Fu, of the threaded rod for the ATS-SBC5H, ATS-SBC6H and ATS-SBC8H is 120 ksi, and for the ATS-SBC10H, ATS-SBC11H and ATS-SBC12H it is 125 ksi. For rod steel ASTM specifications, see reference above.
  5. A minimum flange thickness of 0.258" is required for the structural steel beam.
