Channel Loading
  CHANNEL LOADING
Channel loading generally occurs in one of the following modes:
• beam
• column • flange
BEAM LOADING
BEAM LOADING – PVC
The data listed in the Beam Loading Chart reflects testing conducted on Polyester (Type P) and vinyl ester (Type V) channels. PVC (Type E) material will differ from the Polyester/Vinyl ester Beam Loading Chart. To obtain the beam loading for PVC channel, reduce the load as follows:
(Polyester/Vinyl Ester Beam Load) PVC Beam Load = –––––––––––––––––––––––––––––
NOTE: PVC is not recommended for lengths over 24". COLUMN LOADING
Beam loading data reflects
the maximum uniform load
allowed when using the
channel horizontally as in a
trapeze hanger. Refer to the
table on Page 13 for simple
beam loading capacity of various channels. Use the beam loading conversion chart on page 12 to calculate loading capacity for other beam loading conditions.
The Aickinstrut Trapeze hanger is an example of beam loading. To calculate the maximum allowable beam load for an Aickinstrut Trapeze hanger:
1. Measure the distance between the two threaded rod supports.
2. Using the length of the section hanger as the“beam”, refer to the appropriate profile size in the Beam Loading Chart to determine whether the deflection meets your requirements.

 Column loads are forces applied directly to the end of the channel. Refer to the table on Page 13 for column loading capacity of various channels.
COLUMN
 An example of a typical column LOAD load would be the pressure
exerted on a leg of an Aickinstrut
Battery Rack.
