Expanded Metal Machine vs Perforated Metal Machine: Which One Is Right for You? How do you choose? Then you will know how to choose after understanding a few factors.
Process Comparison
Expanded Metal (DAPU DP Series)
Method: Slitting and stretching – preserves material strength.
Waste: 5% (ideal for copper/aluminum, where raw material costs are high).
Speed: DP-25T produces 30m/min vs. 10m/min for perforation.
Perforated Metal
Method: Punching holes – weakens structural integrity.
Waste: 20–30% (critical for steel-dependent industries).
Cost & Durability
| Factor | DAPU Expanded Mesh | Perforated Metal |
|---|---|---|
| Material Cost (per m²) | $4.2 (steel) | $6.8 (steel) |
| Maintenance Cost | $1,200/year | $2,500/year |
| Weather Resistance | High (no edge rust) | Low (hole edges rust) |
Regional Use Cases
Expanded Metal Wins When:
Building hurricane-resistant fencing in the Caribbean (DP-100’s 8mm mesh).
Creating lightweight roofing for Colombian warehouses (DP-63T’s aluminum mesh).
Pro Tip: Hybrid operations in Argentina use DP-63T for both techniques by switching tooling, maximizing factory flexibility.
