Pallet Rack Wire Decking Types Explained

Understanding pallet rack wire decking types is essential when designing a safe and efficient warehouse storage system. The right decking improves load support, increases fire safety compliance, and protects both inventory and employees. Because different rack beams require different configurations, selecting the correct decking style ensures long-term performance and structural reliability.

At Atlantic Rack, we help businesses choose the proper decking based on beam style, pallet weight, and warehouse workflow.

1. Flared Wire Decking

Flared wire decking is designed with support channels that flare outward and sit directly on step beams.

Best For:

• Standard step beam pallet racks

• Most general warehouse applications

• Easy drop-in installation

Benefits:

• Quick and secure installation

• Excellent weight distribution

• Cost-effective and widely used

This is one of the most popular and versatile wire deck options in the industry.

2. Step Channel Wire Decking

Step channel decking is built specifically for step beams, where the support channel rests inside the step of the beam.

Best For:

• Step beam racking systems

• Heavy-duty pallet loads

• Applications requiring extra stability

Benefits:

• Flush fit inside beam step

• Strong vertical support

• Improved load stability

This option is ideal when higher load capacities are required.

3. Inside Waterfall Wire Decking

Inside waterfall decking features a front and rear “waterfall” that wraps over the beam for added security.

Best For:

• Preventing deck movement

• High-traffic warehouses

• Increased safety applications

Benefits:

• Extra stability

• Reduces deck displacement

• Enhanced beam coverage

The waterfall design helps prevent shifting and improves rack integrity.

4. Inverted Flared Wire Decking

Inverted flared decking is designed for box beams or structural beams where traditional flared decks may not fit properly.

Best For:

• Box beam systems

• Structural pallet racks

• Custom rack configurations

Benefits:

• Secure fit on non-step beams

• Flexible installation

• Strong underside support

This is a great solution when working with non-standard beam types.

5. Inverted Step Channel Decking

Inverted step decking is built for structural or box beams and provides step-style reinforcement underneath.

Best For:

• Structural pallet rack systems

• Heavy industrial loads

• Distribution centers

Benefits:

• Strong reinforcement

• Designed for non-step beams

• High load capacity

This decking style is often used in heavy-duty warehouse environments.

6. Flat Wire Decking

Flat wire decking sits evenly across beams without waterfall edges.

Best For:

• Shelf-style storage

• Carton flow support

• Lighter loads

Benefits:

• Smooth surface

• Ideal for hand-stacked inventory

• Simple, clean design

Flat decking works well when pallets are not the primary storage method.

Why Wire Decking Matters

Choosing the correct wire deck impacts:

• Load capacity

• Worker safety

• Fire code compliance

• Inventory protection

• Rack system longevity

Wire decking allows sprinkler systems to function properly by permitting water to flow through levels, unlike solid shelving. It also prevents pallets from falling through beams and reduces product damage.

How to Choose the Right Wire Deck

When selecting wire decking, consider:

• Beam type (step beam vs. structural beam)

• Pallet size and weight

• Warehouse traffic levels

• Fire code requirements

• Future expansion plans

At Atlantic Rack, we evaluate your rack system and inventory needs to ensure you get the safest and most cost-effective solution.
