Published design loads are based on usage at 70 degrees F. (21 degrees C)
See Table for reduction of load for increased temperature applications.
All beams should be supported in a manner that prevents rotation at supports.
Long, deep beams should be tied between supports to prevent twist
For concentrated loads: Reduce allowable loads by 50% and reduce deflections by 25%,
*Maximum loads are based on full lateral support of the channel, rotation prevention at the support points and the design safety factor of 4:1
**Load exceeds maximum allowable stress for 4:1 safety factor.
***For Beam Spans over 36” with loads approaching these maximum design limits, please contact the manufacturer’s technical representative to confirm support configuration and lateral stability.

Column Loads:

Table lists the total allowable concentric axial load for various unsupported column heights based on a minimum safety factor of 4:1. Eccentric loads should be reduced according to standard practice. ***With column top and bottom pin connected n=1 and loads in table may increase by 4x.
