Plain City, Ohio– Occasionally, though not often, we will get a call for Pallet Rack to be installed on an uneven or unlevel surface. In applications where the concrete is old, cracked or uneven, steel shims can be utilized to help level the base. It is imperative that Pallet Racking be installed on flat or level surfaces. So simplistic in design, steel Shims can help!
Shims come in a range of different styles. It is important that you pick the correct pallet rack shim plate to match the brand of upright and size of the footplate. Upright footplates can vary in design, as a result, it is very important to use only factory approved shims, as the are specifically sourced for the design of the Uprights.
Depending on the severity of the base, there may be a need to use more than one shim. If that is the case, there are very specific guidelines to follow as to how many are safe and how to secure them in place to prevent shifting.
- Shim stack cannot exceed six times the diameter of the largest anchor bolt.
- Shim stack that is less than two times the anchor’s diameter does not require locking shims together by welding or installing a second anchor.
- Shim stacks between two times but less than six times the diameter of the anchor must be locked by welding or adding a second anchor. If shims are not welded or secured with a second anchor, they can spin out, causing rack instability.
- Shim stacks may require longer anchor bolts.
