Both mesh and perforated sheet are used in similar applications—like filtration, fencing, ventilation, and decoration—but they’re made differently and serve slightly different purposes. Here's a breakdown:
Mesh (including expanded metal and woven wire)
Definition: A grid-like structure made by expanding metal or weaving wires together.
Types:
Expanded Metal Mesh: Made by cutting and stretching a metal sheet to form diamond-shaped openings.
Woven Wire Mesh: Made by weaving metal wires over and under each other (like fabric).
Welded Wire Mesh: Wires are welded at intersections for a rigid structure.
Advantages:
Strong and durable.
Allows air, light, and liquid through.
One-piece construction (expanded mesh = no welds).
Often cheaper per area for large ventilation/safety uses.
Perforated Sheet
Definition: A solid metal sheet that's been punched or laser-cut with holes in specific patterns (round, square, slotted, decorative).
Advantages:
Clean, aesthetic appearance.
Precise, uniform holes.
Available in decorative patterns.
Smooth surface—less likely to catch/snag.
Key Differences at a Glance
| Feature | Mesh | Perforated Sheet |
| Structure | Grid of open spaces (woven or cut) | Solid sheet with punched holes |
| Airflow | High | Medium |
| Strength | Strong (especially expanded mesh) | Varies with hole size/pattern |
| Aesthetics | Industrial | Clean/modern |
| Customization | Varies with mesh type | Highly customizable patterns |
| Cost | Generally cheaper | Usually more expensive |
