Design, Manufacturing & Benefits
1. Core Technical Specifications
A. Material Selection Guide
Material | Thickness Range | Key Properties | Best Applications |
---|---|---|---|
304 Stainless | 0.8-3.0mm | Corrosion-resistant, food-grade | Outdoor/high-humidity installs |
Aluminum 5052 | 1.0-4.0mm | Lightweight, EMI shielding | Telecom/RF equipment |
Galvanized Steel | 0.6-2.5mm | Cost-effective, durable | Industrial control cabinets |
Electro-galvanized | 0.5-2.0mm | Superior paint adhesion | Consumer electronics |
▶ Pro Tip: Use 1.2mm cold-rolled steel (SPCC) for 95% of indoor industrial enclosures
B. Critical Tolerance Standards
- Cutting: ±0.1mm (Laser) / ±0.3mm (Punch)
- Bending: ±0.5° angle / ±0.2mm positional
