| Wire Decking | Welded carbon-steel wire with formed steel channels | Commonly sized to rack beam depth and bay width; mesh openings often range from approximately 50 × 100 mm to 75 × 100 mm | Supports pallets, improves load visibility, and helps prevent loose cartons from falling through the beams | Powder-coated or galvanized steel is suitable for general warehouses; galvanized finishes are preferable in humid or corrosive areas | Weld quality, beam-seat engagement, coating adhesion, deflection under rated load, and resistance to impact damage | Verify uniformly distributed load and concentrated-load ratings against the rack layout; inspect for bent channels, broken welds, and corrosion | 5 | 4 |
| Pallet Supports | Cold-formed steel, usually powder-coated or galvanized | Designed to fit between front and rear beams; available as bars, channels, or adjustable supports | Provides additional pallet support where pallet boards or stringers do not safely span the beam spacing | Galvanized steel offers improved resistance to moisture; painted steel requires protection from chipped or exposed areas | Correct seating, anti-roll design, adequate section thickness, and resistance to repeated pallet impact | Check the support’s rated capacity, beam compatibility, spacing, and ability to remain seated during pallet placement | 5 | 4 |
| Column Protectors | Steel, molded polyethylene, polyurethane, or recycled rubber | Common heights range from approximately 300 to 1200 mm; profile must match upright dimensions | Absorbs or deflects impacts from forklifts, pallet trucks, and handling equipment | Polymer guards resist moisture and many chemicals; steel guards provide high rigidity but may transfer impact force to the upright | Impact-energy rating, secure anchoring, UV stability, low-temperature performance, and resistance to cracking or permanent deformation | Select a guard that protects the full vulnerable zone without obstructing base plates, anchors, or aisle clearance | 5 | 5 |
| Row Spacers | Formed or welded steel with a protective coating | Usually selected to maintain a defined back-to-back rack clearance; spacing must follow the rack design | Maintains alignment and separation between rack rows while limiting unintended contact | Use coated or galvanized steel in areas exposed to condensation; avoid dissimilar-metal contact that may accelerate galvanic corrosion | Accurate hole pattern, adequate welds, stable fasteners, and resistance to loosening from vibration or rack movement | Confirm that the spacer does not replace a required structural brace and that installation follows the rack manufacturer’s design | 4 | 4 |
| Back-of-Rack Safety Netting | Knotted or knotless high-tenacity synthetic fiber, commonly polyethylene or nylon | Mesh size is selected according to the smallest item that must be retained; panel height follows the rack configuration | Restrains cartons and materials from falling into walkways or adjacent operating areas | Polyethylene generally offers good moisture resistance; nylon can absorb moisture and requires appropriate environmental selection | Tensile strength, tear resistance, UV protection, edge reinforcement, attachment integrity, and visible damage after impact | Use only with documented mesh strength and fixing details; inspect for cuts, abrasion, overstretching, and missing ties | 5 | 3 |
| Beam Safety Locks | Spring steel, stamped steel, or positive locking pins | Must match the beam connector geometry and upright perforation pattern | Prevents accidental beam uplift or disengagement during forklift contact and operational vibration | Zinc-plated or coated steel is commonly used; select corrosion-resistant finishes for damp environments | Positive engagement, resistance to deformation, retained position after impact, and ease of visual inspection | Every beam connection should have the specified locking device installed and visibly engaged before loading | 5 | 4 |
| Pallet Stop Beams | Structural steel tube, angle, or formed steel section | Positioned at the rear of the storage location; height and clearance must suit the pallet and load profile | Limits pallet travel and helps prevent loads from being pushed beyond the rack’s intended depth | Powder coating or galvanizing improves corrosion resistance; exposed edges should be protected against impact and rust | Connection strength, beam straightness, impact resistance, clearance from stored goods, and absence of sharp edges | Do not use as a substitute for load backstops or structural components unless included in the engineered design | 4 | 4 |
| Load and Aisle Identification Labels | Printed polyester, laminated vinyl, aluminum, or rigid plastic | Letter height should be selected for viewing distance; labels must remain legible from normal operating aisles | Communicates safe working load, location identity, operating instructions, and inspection information | Choose UV-, abrasion-, moisture-, and chemical-resistant materials for demanding warehouse conditions | Adhesive performance, print permanence, resistance to cleaning agents, and retention of contrast over time | Replace labels whenever load configurations, beam levels, or rated capacities change; never rely on faded or unreadable signage | 4 | 3 |
