Why Use This Product

Use a structural, all-welded upright frame when you need dependable rack performance under heavier loads, frequent forklift traffic, and daily operational wear. Upright frames are the backbone of selective pallet racking, and choosing a heavy-duty structural frame helps reduce sway, maintain alignment, and improve overall rack stability compared to lighter-duty designs. This model is designed to meet AISC and RMI standards, making it a strong fit for facilities that prioritize engineering-based rack layouts and consistent, repeatable storage capacity 

How It Helps Your Operation?

This upright frame helps your operation increase usable vertical storage while keeping layouts organized and adjustable. Select your upright height based on ceiling height, sprinkler requirements, and forklift lift limits, then set beam elevations to match pallet loads and picking needs. Depth selection matters too, because pallet overhang supports safe handling and protects loads. As a reference, a 48-inch deep pallet commonly pairs with a 42-inch deep upright to allow about 3 inches of overhang in front and 3 inches in back. For capacity planning, upright systems can support up to 54,200 pounds per bay when configured with 60-inch vertical beam spacing or less, with final capacity depending on beams, spacing, and the full rack design
