Since you previously asked about **Conveyor Mesh, and are now asking about **Welded Wire Mesh**, it is important to clarify that while both are made of wire, they serve fundamentally different purposes.
Conveyor Mesh** (woven or hinged) is designed to *move* dynamically around rollers.
Welded Wire Mesh** is a rigid, static sheet or roll where wires are fused (resistance welded) at every intersection. It is typically used for fencing, reinforcement, and guarding.
Here is a breakdown of Welded Wire Mesh, particularly how it compares to the conveyor mesh discussed previously.
1. How It Is Made
Unlike woven mesh (which can unravel if cut) or hinged conveyor belts (which are flexible), welded wire mesh is constructed by taking a grid of wires and welding them together at the junctions using electric resistance.
Result:** A rigid panel that does not flex or come apart when cut.
2. Common Types & Materials
Galvanized Before Weld (GBW):** Wires are galvanized individually, then welded. The weld points are bare (prone to rust if exposed to moisture), but the wire surfaces are coated.
Galvanized After Weld (GAW):** The panel is welded first, then dipped in galvanized zinc. This coats the weld points as well, offering the best corrosion resistance (common for fencing).
Stainless Steel (304/316):** Welded for high corrosion resistance; used in food processing, chemical plants, and architectural applications.
PVC Coated:** Steel mesh coated in plastic for aesthetics and extra corrosion protection (common in residential fencing and animal enclosures).
3. Key Characteristics
Rigidity:** It holds its shape. It does not stretch or conform to curved surfaces easily.
Strength:** The welded intersections provide high shear strength.
Stability:** It does not “unravel” if the edge wire is cut (a common issue with woven wire fencing).
4. Common Applications
Industrial Safety (Machine Guarding):** This is where it overlaps with conveyor systems. Welded wire mesh panels are often placed around *conveyors* to create safety cages, preventing workers from touching moving parts while allowing visibility.
*Construction:** Reinforcing concrete slabs and walls (rebar mesh).
*Fencing:** Security fences, animal cages, zoo enclosures, garden fencing.
*Storage:** Partition walls in warehouses, pallet rack backing (to prevent products from falling through).
*Architecture:** Infill panels for railings, facades, and security screens.
5. Comparison: Conveyor Mesh vs. Welded Wire Mesh
| Feature | Conveyor Mesh (Woven/Hinged) | Welded Wire Mesh |
Structure** | Flexible, continuous belt | Rigid, flat panel or roll |
Movement** | Designed to move (dynamic) | Designed to stay still (static) |
Intersections** | Spirals, rods, or hinges (mechanical) | Fused metal (electrical weld) |
Cutting** | Edges must be sealed or welded to prevent unraveling | Can be cut with grinders; edges remain stable |
Typical Use** | Baking, freezing, washing parts | Fencing, safety guarding, concrete reinforcement |
6. Selecting the Right Mesh
If you are selecting welded wire mesh, you will usually specify three things:
1. **Wire Gauge (Diameter):** Thicker gauge (e.g., 6 gauge) for structural strength; thinner gauge (e.g., 14 gauge) for light fencing.
2. **Opening Size:** (e.g., 2″ x 2″, 1″ x 1″, 1/2″ x 1/2″) — Smaller openings keep out small animals or contain small parts; larger openings reduce weight and cost.
3. **Material:** Galvanized steel for outdoor fencing; stainless steel for food/chemical environments; PVC coated for decorative security.
Are you looking for safety guarding for an existing conveyor system, or are you looking for fencing/reinforcement?** If you can clarify the application, I can help you determine the appropriate wire gauge and material.
