1. Calculating Upright Capacity

The upright frames support the entire rack system’s weight. They absorb dead loads (static weight of the rack itself) and live loads (fluctuating weight of stored inventory).

Key Factors:

• Frame dimensions: height, depth, and column width.
• Material type: cold-formed or hot-rolled steel.
• Manufacturer specifications: load ratings for different frame sizes.

2. Calculating Beam Capacity

Beam strength depends on length and depth, as gravitational forces impact compression and tension distribution.

Load Rating Examples:

3. Rating Bowing or Deflection of Pallet Rack Beams

Beams are designed to bow slightly under weight. Deflection is normal but must remain within safety tolerances.

Safety Warning:

Excessive beam deflection can indicate overloading and compromise structural integrity.

4. Calculating Deck Capacity

Decks stabilize pallet loads, ensuring uniform weight distribution across beams.

Load Types:

• Uniform loads: Even weight distribution across the deck.
• Point loads: Concentrated weight in specific areas (e.g., pallet skids).

How Much Can a Pallet Rack Hold?

The total weight capacity of a racking system depends on all components working together. It’s crucial to consult an expert to ensure safety and efficiency.
