How Height-To-Depth Ratio Contributes To Overall Storage Rack Stability

A key objective of safe rack design is to ensure the finished structure won’t topple over when subjected to horizontal forces such as an earthquake, forklift impact, or high wind. To significantly minimize this risk, Section 8.1 of RMI’s ANSI ...

Beware Of Leaning Or Bowed Pallet Rack Columns

While some column distortion may be acceptable in a loaded industrial steel pallet rack structure, if a column is leaning (out-of-plumb) or bowed (out-of-straight) beyond a certain point, its capacity will be significantly reduced. Those conditions are unsafe and increase ...
