Types of Wire Mesh Decking: Standard, Flared, Waterfall & More

Wire mesh decking is a key safety and load-support component in pallet racking systems. While it may appear to be a standard accessory, wire mesh decking is available in multiple configurations designed to fit different beam types, load requirements, and warehouse applications.

This guide explains the most common wire mesh decking types, how they differ, and when each should be used.

What Is Wire Mesh Decking?

Wire mesh decking consists of welded steel wire panels supported by reinforced channels that sit directly on pallet rack beams. It provides stable load support while allowing airflow, visibility, and fire sprinkler water penetration.

Wire mesh decking is widely used in selective pallet racking, carton flow racks, and shelving systems.

Why Decking Type Matters

Choosing the correct wire mesh decking type affects:

• Load distribution and rack safety
• Compatibility with beam profiles
• Fire code compliance
• Ease of installation and future reconfiguration

Using the wrong decking type can lead to instability, poor fit, or reduced load capacity.

Standard Wire Mesh Decking

Standard wire mesh decking features straight support channels that sit directly on top of pallet rack beams.

Key Characteristics

• Flat channel design
• Commonly used with box beams
• Easy installation and replacement
• Cost-effective option

Applications

• Light to medium pallet loads
• Uniform pallet sizes
• General warehouse storage

Flared Channel Wire Mesh Decking

Flared channel decking uses outward-angled channels that rest securely on step beams without additional clips.

Key Characteristics

• Flared channel ends
• Designed specifically for step beams
• Improved stability without fasteners
• Faster installation

Applications

• Selective pallet racking with step beams
• High-volume distribution centers
• Facilities requiring quick system changes

Waterfall Wire Mesh Decking

Waterfall decking includes extended wire mesh edges that “waterfall” over the front and rear beams.

Key Characteristics

• Enhanced load retention
• Prevents cartons from sliding off beams
• Added safety at pick faces

Applications

• Carton storage
• Order picking areas
• Mixed SKU environments

Inside Waterfall vs. Outside Waterfall Decking

Inside Waterfall

Waterfall drops inside the beam

Maintains a flush rack front

Preferred for palletized storage

Outside Waterfall

Waterfall drops outside the beam

Additional product stop protection

Ideal for loose cartons and manual picking

Heavy-Duty Wire Mesh Decking

Heavy-duty decking uses thicker wire gauge and additional support channels to handle higher loads.

Key Characteristics

• Increased load capacity
• Reinforced channel desig
• Suitable for dense or heavy pallets

Applications

• Industrial warehouses
• Manufacturing facilities
• High-weight pallet storage

Reverse Waterfall Wire Mesh Decking

Reverse waterfall decking places the waterfall at the rear of the rack, preventing pallets from being pushed too far back.

Key Characteristics

• Rear load stop function
• Improves rack safety
• Reduces risk of pallet overhang

Applications

• Back-to-back racking
• Narrow aisle systems
• Facilities with forklift-only loading

Galvanized vs. Powder-Coated Decking

Galvanized Decking

Superior corrosion resistance

Suitable for cold storage or high-humidity environments

Powder-Coated Decking
Clean appearance

Cost-effective for dry indoor warehouses

How to Choose the Right Wire Mesh Decking Type

When selecting wire mesh decking, consider:

1. Rack beam type (step beam or box beam)
2. Pallet weight and load distribution
3. Storage method (palletized or carton)
4. Fire safety and code requirements
5. Environmental conditions
6. Consulting a racking specialist ensures compatibility and compliance.

Conclusion

Wire mesh decking is not a one-size-fits-all solution. Standard, flared, waterfall, and heavy-duty configurations each serve specific purposes. Selecting the correct type improves safety, load stability, and long-term performance of your pallet racking system.
