Pallet Rack Upright Frame

Pallet rack upright (also called frame, or column) is the vertical support structure in a pallet racking system. It forms the backbone of the rack, providing stability and load-bearing capacity. Uprights connect with cross beams to create shelving levels for pallet storage.

Pallet rack uprights provide a frame for building a pallet rack to provide organized storage for palletized loads or large containers. These vertical uprights connect to pallet rack beams to create racking sections for storing products and materials on pallets, which are easily accessible to forklifts.

Pallet racking uprights are critical to the structural integrity and strength of your warehouse storage solutions. It’s important to select the correct pallet rack upright to support the load the pallet racks will bear, as well as to ensure they interlock securely with any existing pallet rack storage already in place. Pallet racking uprights come in a variety of gauges to easily support the weight of the stored goods.

Features of Pallet Rack Uprights

1. Design & Construction

Material: 

Made from high-strength steel (typically 12–16 gauge).

Shape:

Open-back (dexion or teardrop design) – Most common; beams hook into holes.

Boxed (structural uprights) – Fully enclosed for heavy-duty use.

Perforations: Vertical slots or holes for adjustable beam heights.

2. Components of an Upright Frame

Columns (Verticals) – Two side posts.

Braces (Lacing) – Diagonal/ horizontal bars for stability.

Base Plate – Anchored to the floor for support.

Footplate – Distributes weight to prevent tipping.

How Uprights Work with Beams

Beams slot into holes on uprights at desired heights.

Safety clips (beam locks) secure beams in place.

Adjustable spacing allows customization for different pallet sizes.

Load Capacity Factors

Upright Height – Taller frames may reduce capacity.

Thickness (Gauge) – Thicker steel = higher capacity.

Bracing Design – More bracing improves stability.

Anchoring – Must be bolted to the floor for safety.

Installation Tips

✔ Use a level to ensure uprights are perfectly vertical.

✔ Anchor securely to prevent tipping.

✔ Follow manufacturer’s load charts for safe weight limits.
