Must pallet racking be bolted to the floor?
Updated: Apr 22, 2021
The answer is yes storage racks should always be bolted down where mechanical handling equipment operates or where there are other forces that may overturn storage racks. The following describes the what and how:
Pallet racking should be installed on a solid stable base that provides adequate support and anchorage for the floor plate and fixings.
Single rows of racking should have suitable floor fixings to every foot plate (see below).
For back to back pallet racks installed before 2010:
Where sufficient row spacers are present and a height to depth ratio does not exceed 6:1, only the perimeter uprights need be floor fixed.
Where the height to depth ratio exceeds 6:1 but does not exceed 10:1 all uprights require floor fixings.
Where the height to depth ratio exceeds 10:1 but does not exceed 20:1 each frame should be restrained by connections to other substantial structures providing that they are capable of providing this support. This condition will be satisfied if the rack is connected at the top to an adjacent double-sided rack frame.
For back to back pallet racks installed from 2010 onward.
The 2010 SEMA guidelines revises the requirement for floor fixings and now requires floor fixings to all footplates in back to back racks. This applies to racks installed from 2010 onward but is not retrospective.
These fixings should be applied through the base plate of the upright and be capable of resisting the anticipated horizontal shear and vertical uplift forces.
