Technical Information:

Aluminum Unistrut is a light weight alternative to steel Unistrut, however with the reduced self weight comes greatly reduced performance. The Aluminum Unistrut uses a 33% reduction factor for all beam and column loading. Slip and Pull Out loading for the extruded aluminum is determined by multiplying the load data of steel channel nuts by 75% for slip resistance and 50% for pull out load.
