How much weight can a 14 gauge Unistrut hold?īeam Loading – Unistrut P4100 – 1-5/8″ x 13/16″, 14 Gauge Metal Framing Channel Span (in)
Unistrut uses ASTM A1011 SS GR33 steel strip for forming channels. This material has virgin yield strength of 33,000 psi. Tests performed by Unistrut show that after cold-forming, strength has increased to 42,000 psi. To attach the Unistrut to your trusses, use the bolt, washer, and nut sets labeled “S2TR”. You should use 1 each “S2TR” set per truss. The bolt will thread through the space between the bars in your truss and then down through the Unistrut. Unistrut connections provide the strength of welding but can easily be taken apart.
