1. While manufacturers may publish capacities for their pallet supports, they don’t actually add capacity to the beam level.**
2. Like wire decking, pallet supports are not designed for point or impact loading. Uniform distributed loading is the rule.
3. Again like wire decking, pallet supports are designed as a safety measure to prevent pallets from falling through the beams if loaded incorrectly. The beams should always support the pallet.
4. A good rule-of-thumb is that crossbars are only intended to carry 25% of the pallet weight.
5. Beams longer than 90″ should have one pallet support mid-span to prevent beam spreading.
6. Tabbed or roll-in crossbars are for use with slotted beams.
7. Flanged or top-hat pallet supports are for use with beams without slots and can be tek-screwed in place to prevent sliding.
8. Crossbars are manufacturer-specific due to differences in slot punching and step depths.
**Note: Number 1 is true for roll-formed rack. Structural crossbars do add capacity due to how they are designed and installed.
