Drop-In Wire Decking

Drop-In Wire Decking is a welded steel mesh panel installed between pallet rack beams to form an open storage surface. The panel combines welded wire mesh with formed support channels that transfer loads from the deck surface to the rack beams.

It is used for palletized goods, cartons, bins and industrial materials. Panel dimensions, mesh opening, wire diameter, support-channel layout and surface finish are selected from the rack configuration and storage load.

Welded Wire Mesh
Longitudinal and cross wires are resistance welded at each intersection to form the deck surface. Wire diameter and mesh opening determine the basic mesh construction and support pattern.
Support Channels
Formed steel channels are welded beneath the mesh. They provide the bearing structure between the mesh surface and rack beams, with quantity and spacing matched to panel dimensions.
Edge Profile
The formed edge provides a defined bearing area on the rack beam. Edge dimensions are coordinated with the panel depth and beam arrangement to maintain a stable deck position.

Beam Span
Measure the actual clear span between the supporting rack beams. The panel width is selected to provide the required bearing at both ends.
Rack Depth
Confirm the front-to-back rack dimension before selecting panel depth. Actual rack dimensions should be used for specification rather than relying only on nominal pallet sizes.
Load Per Level
State the maximum intended load for each storage level. Pallet weight, load distribution and contact area should be considered when determining the deck construction.

Mesh Opening
50 × 100 mm and 75 × 100 mm openings are common configurations for pallet rack decking. The opening should correspond to the size and support requirements of the stored materials.
Wire Diameter
Wire diameter from 3.5 to 6.0 mm provides different mesh construction options. Selection depends on panel dimensions, load requirements and required deck rigidity.
Channel Arrangement
Support channels distribute loads from the welded mesh to the rack beams. Channel quantity and spacing should be established from panel size and loading conditions.

Distributed Loads
Load performance is determined from the complete panel structure. Wire diameter, mesh opening, panel dimensions and support-channel arrangement work together in the load calculation.
Point Loads
Pallet feet, narrow containers and concentrated material loads place load over smaller areas. The actual contact pattern should be included when confirming the panel specification.
Rack Compatibility
The deck forms one part of the storage system. Beam span, beam capacity and deck construction should be evaluated together for the specified storage level.

Powder Coating
Powder coating provides a finished steel surface for general warehouse environments. Standard or project-specified coating colors can be applied.
Galvanized Finish
Galvanized steel provides a zinc-coated surface for applications requiring additional corrosion protection. Coating requirements can be specified according to the service environment.

Pallet Storage
The open mesh surface supports pallets positioned directly between rack beams while maintaining visibility through the deck.
Carton and Bin Storage
Cartons, bins and containers can be stored directly on the mesh surface when the selected opening and wire construction suit the load.
Industrial Warehouses
Common installations include distribution storage, production material storage, spare-parts areas and general warehouse rack levels.

Wire Preparation
Steel wire is straightened and cut to controlled lengths before mesh assembly. Wire diameter is checked against the specified construction.
Resistance Welding
Crossing wires are resistance welded at each intersection. Weld consistency is monitored during mesh production.
Channel Assembly
Formed support channels are positioned beneath the mesh according to the approved panel drawing and welded into the required locations.
Final Inspection
Panel width, depth, mesh opening, wire diameter, channel position and surface condition are checked against the production specification before packing.

Flat Stacking
Finished panels are stacked horizontally to maintain panel geometry during handling and transportation.
Surface Protection
Protective packing is applied where required to reduce surface contact and handling marks during shipment.
Identification
Packing records can include panel dimensions, quantity, finish and specification details for receiving and installation control.

Provide the rack beam span, rack depth, required panel dimensions, load per level, mesh opening, wire diameter, support-channel arrangement, surface finish and quantity when requesting a quotation.
For non-standard rack systems, provide a drawing showing beam dimensions and deck installation conditions. This information allows the panel structure, dimensions and capacity requirements to be reviewed before production.
