Core Pallet Rack Accessory Lineup

Wire Mesh Decking

Improve fire safety, overhead lighting, and load capacity across all beam levels.

Wire mesh decks fit securely over step beams or structural box beams to form a sturdy, breathable shelf surface. Unlike solid wood or metal decking, wire mesh allows overhead fire sprinkler water and lighting to pass through while preventing loose inventory from falling.

Waterfall Edge Design: Standard drop-over outer waterfall edge wraps around the beam face to prevent deck displacement during loading.
Channel Options: Available in Universal Step Channels (for standard step beams) and Flared Channels (for structural or box beams).
Capacities: Heavy 2″ x 4″ 6-gauge welded wire grid supports loads from 2,000 lbs to 2,500+ lbs per deck.
Finish: Durable, rust-resistant powder coat or galvanized finishes for long-lasting performance.

Pallet Safety Supports (Cross Bars)

Heavy-duty secondary support for non-standard, weak, or damaged wooden pallets.

Pallet safety supports (or crossbars) span between the front and rear rack beams to prevent wooden pallets from sagging or falling between the beams.

Flanged Safety Supports: Drop over the top of standard step beams with pre-punched holes for secure tek-screw anchoring.
Flush Mount Supports: Sit flush with the top of the step beam, creating a flat surface for non-standard hand-picked loads.
Structural Steel Capacity: Rated up to 3,000 lbs per pair, ensuring heavy pallet loads remain stable across every shelf tier.

Row Spacers

Maintain consistent flue space alignment and structural stability across double-entry rack rows.

Row spacers connect back-to-back pallet rack upright frames, keeping rows parallel and maintaining mandatory flue spaces required by fire codes and building inspectors.

Flue Space Compliance: Stocked in 6″, 8″, 12″, and custom lengths to ensure proper clearance for overhead sprinkler penetration.
Heavy Steel Construction: Formed from 12-gauge or heavy structural steel angles to lock back-to-back uprights into a single rigid matrix.

Pallet Back Stops (Safety Stops)

Prevent pallets from pushing through the rear of the rack into wall spaces or adjacent aisles.

Pallet back stops act as a rigid mechanical barrier mounted along the back beam level, giving fork truck operators a clear physical stop point when placing heavy loads.

Wall & Equipment Protection: Prevents pallets from colliding with building walls, electrical conduits, or inventory in the opposite row.
Offset Design: Available in flush-mount or 3″-6″ offset configurations to accommodate proper pallet overhang.

Concrete Anchors for Pallet Racks & Shelving

Seismic-rated heavy-duty wedge anchors engineered for ultimate rack base security.

Unanchored or improperly anchored pallet rack frames violate OSHA regulations and regional seismic building standards. We supply industrial-grade concrete expansion wedge anchors engineered to lock upright base plates directly into concrete slab foundations.

Sizes Stocked: Heavy ½″ and ¾″ diameter anchors in lengths from 3¾″ to 7″.
Seismic Code Approved: Meets or exceeds strict Southern California high-pile storage and seismic anchorage specifications.

Guard Rails & Rack End Protectors

Absorb high-energy forklift impacts before they crush structural rack uprights.

Forklift collisions are the leading cause of catastrophic rack collapses. Our heavy structural steel guard rails and post protectors shield exposed column bases and row ends from costly impact damage.

Post Protectors (Column Protectors): Anchor directly in front of rack base plates to shield front upright legs from low-level fork impacts.
Heavy-Duty End-of-Aisle Guards: High-visibility, safety-yellow structural steel barriers that shield vulnerable aisle turns and heavy-traffic corridors.

Why Invest in Heavy-Duty Rack Safety Accessories?

OSHA & Fire Code Compliance: Satisfies mandatory building requirements for flue space clearance, base plate anchoring, and sprinkler water penetration.
Lower Maintenance Costs: Protecting rack uprights with $100 guard rails prevents multi-thousand-dollar frame collapses and costly teardowns.
Worker Injury Prevention: Prevents loose cartons, failing pallets, or dislodged inventory from falling into active pedestrian aisles.

Rack Accessories Frequently Asked Questions (FAQs)

What is the difference between step channel and flared wire decking?

Step channel wire mesh decks feature support channels with notched ends designed specifically to sit inside the step of standard step beams. Flared channel wire decking features flared channel ends that lay flat across the smooth top surface of box beams or structural channel beams.

Why are row spacers required for back-to-back pallet rack rows?

Row spacers connect back-to-back rack uprights, keeping rows parallel and structurally tied together. More importantly, they maintain a consistent 6″ to 12″ longitudinal “flue space” between rows, which is legally mandated by fire codes to allow heat from a fire to rise quickly and activate overhead sprinklers.

How many concrete anchors are required per pallet rack upright frame?

Standard warehouse safety codes require every pallet rack upright base plate to be anchored to the concrete floor slab with at least one anchor per foot (typically two wedge anchors per base plate). High-seismic regions like Southern California may require specialized ¾″-diameter anchor configurations based on engineering calculations.

Can pallet safety supports replace wire mesh decking?

Pallet safety supports (cross bars) are designed specifically to support full wooden pallets across two rack beams. They do not provide a continuous shelf surface. If you plan to store loose cartons, hand-picked inventory, or variable-sized loads, wire mesh decking is required.
