Pallet Rack Decking
Pallet rack decking is welded steel mesh that sits on rack beams to support loads and keep items from falling through. PalletRackNow says Standard wire decks are usually rated between 1,500 and 2,500 lbs UDL. Its JL4846 waterfall-flare deck is listed at 2500 lbs Capacity. Norlift lists standard load capacity of 2,000 to 2,500 pounds.

Wire Mesh Decking Types
Step, flare, and flush
- Step / waterfall: SJF says Standard (aka step) style decking with waterfalls sit in the steps of rack beams.
- Flared flange: SJF says This style of wire deck features a flared flange at each end. PalletRackNow lists Flare Channel (Waterfall): Designed for more universal use on structural C-channel beams and box beams that do not feature a standard step.
- Flush: SJF says Flush decks are exactly the same as standard style – only they do not have a waterfall that wraps around the rack beam.
- Waterfall width: iWarehousing says Waterfalls, as a standard, are designed to be at 1.5” width.
- Step vs flanged strength: iWarehousing says Step channel supports provide greater strength than flanged.
Other decking materials
- Wire mesh: ECS lists Wire Mesh Decking The most common option — available in step-channel, flared, or flush styles. Wire mesh is the best all-purpose option.
- Bar grating: ECS lists Bar Grating Decking Industrial steel grid designed for the heaviest loads.
- Wood: ECS lists Wood Decking Plywood or dimensional lumber.
- Perforated / slotted steel: ECS lists Perforated or Slotted Steel Decking A hybrid between solid and mesh.
- WW Cannon menu: Choose from Welded-Wire, Perforated/Punched, Slotted, or Solid Steel Decking — making it compliant with ANSI MH26.2-2017 standards.
Capacity and sizing
PalletRackNow says Wire decking is rated by uniformly distributed load (UDL), which is the total weight evenly spread across the entire deck surface. Standard wire deck depths include 24”, 36”, 42”, 48”, 60”, and 72”. Standard widths include 34”, 48”, 52”, and 58”. SJF says Standard depths are 24", 36", 42", 44" and 48" deep.

Sprinkler and fire considerations
PalletRackNow says wire mesh allows sprinkler water to pass through to lower rack levels, which is a requirement in many fire codes. iWarehousing says water from sprinklers easily flow through the mesh. ECS says solid steel or wood decking can create problems if they block water flow. SJF says Many municipalities now require wire decks in lieu of plywood supports.

- Loose cartons: Individual boxes or packages
- Small items: Products that could fall through beam openings
- Hand-stacked goods: Items placed manually rather than by forklift
Installation and Fit
Sizing
- Beam-to-beam measurement: Inside dimension between beams
- Bay depth: Front-to-back dimension matching published deck depths
- Standard sizes: See PalletRackNow / SJF depth and width figures above
Safety
- Load capacity verification: Match deck UDL to actual load distribution — see PalletRackNow center-load caveat
- Proper fit: Panels should not slide or shift during loading
- Complete coverage: No gaps that allow items to fall through
Applications
- Carton picking: Hand-pick individual cases from rack levels
- Parts storage: Small components in bins or boxes

Frequently Asked Questions
What is pallet rack decking?
Pallet rack decking is a surface on rack beams for loads that cannot sit safely on open beams alone. iWarehousing says A pallet rack wire decking is made of welded steel mesh. ECS lists Wire Mesh Decking The most common option — available in step-channel, flared, or flush styles. American Surplus lists plywood, corrugated steel, PunchDeck, and wire styles.
When do I need pallet rack decking?
Use decking when pallet bottom boards do not span beams, for hand-stacked cartons, loose items, or non-palletized products that could fall through. SJF says Many municipalities now require wire decks in lieu of plywood supports. ECS says Wire mesh is the best all-purpose option for most palletized loads.
What load capacities do pallet rack wire decks support?
PalletRackNow says Standard wire decks are usually rated between 1,500 and 2,500 lbs UDL, but heavy-duty options can exceed that. A 2,500 lb UDL deck does not mean it can hold 2,500 lbs concentrated in the center. Norlift lists standard load capacity of 2,000 to 2,500 pounds with higher capacity options available. SJF stock SKU J2446 lists Capacity(lbs) 2500.
Why is wire mesh decking preferred in sprinklered warehouses?
PalletRackNow says wire mesh allows sprinkler water to pass through to lower rack levels, which is a requirement in many fire codes. iWarehousing says water from sprinklers easily flow through the mesh. ECS says solid steel or wood decking can create problems if they block water flow.
What is the difference between waterfall, flare, and flush wire decking?
SJF says Standard (aka step) style decking with waterfalls sit in the steps of rack beams. Flared style features a flared flange at each end. Flush decks are exactly the same as standard style – only they do not have a waterfall that wraps around the rack beam. iWarehousing says Waterfalls, as a standard, are designed to be at 1.5” width.
