Beam loads shown are total uniform load, including the channel weight, for a simple span supported at each end that is adequately laterally braced. Refer to pages 20 -23 for other beam support conditions.
Refer to page 77 for load reduction factor for an unbraced beam length.
ZSi-Foster Engineering Catalog
Load for punched channel is obtained by multiplying the loads shown by the following reduction factors:
SS - Channel with Short Slots. . . . . . . . . . . . . . 0.90 SL - Channel with Long Slots . . . . . . . . . . . . . . 0.90 H - Channel with Holes . . . . . . . . . . . . . . . . . . . 0.95 KO - Knock-Out Channel. . . . . . . . . . . . . . . . . . 0.95
WARNING: These products can expose you to chemicals including lead, which is known to the State of California to cause cancer, and which is known to cause birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
