    • 10 feet:  10' or 10’ 1/8” (3.05m) ± 1/2" (13 mm)
    • 20 feet:  20' or 20’ 3/8” (6.11m) ± 1/2" (13 mm)

    Load Data:

    • All beam and column load data pertains to carbon steel and stainless steel channels.
    • Load tables apply only to UNISTRUT brand channel. Look for "UNISTRUT" on the product.
    • Load tables and charts are constructed to be in accordance with the SPECIFICATION FOR THE DESIGN OF COLD-FORMED STEEL STRUCTURAL MEMBERS 2007 EDITION published by the AMERICAN IRON AND STEEL INSTITUTE USING ASD METHOD.
    • Loads are based on 33 ksi steel cold formed to 42 ksi.
    • Safety Factor to Yield Strength is 1.67 for Beam Loads and 1.80 for Column Loads.
    • Beam loads are based on a simple beam and are given as a total uniform load (W) in pounds. For proper calculation procedures, refer to our Beam Load Calculation Guide.
    • For bearing loads, reference our bearing loads page.

    Welds:

    • Welded channels are spot welded 2" (51 mm) or 3" (76 mm) on-center.
