Thickened material for network cabinets

Cold-rolled steel and stainless steel with thicknesses from 1.0mm to 1.5mm are commonly used for durable, high-load network cabinets.

Common Materials and Thicknesses

Cold-Rolled Steel (SPCC/SPHC): Widely used for network and server cabinets due to its high strength, rigidity, and cost-effectiveness. Typical thickness ranges from 0.8mm to 2.0mm, with 1.0–1.5mm being standard for main frames and side panels. It supports heavy equipment like servers and UPS units, providing excellent anti-deformation properties for 42U racks and large data center cabinets . Stainless Steel (304): Often used for dust-proof frames, doors, or panels where corrosion resistance is critical. Thicknesses are usually around 0.8–1.0mm, offering durability in humid or outdoor environments while maintaining rust-proof performance . Aluminum Alloy: Lightweight alternative with good corrosion resistance, but lower load-bearing capacity. Suitable for lightweight or portable network cabinets, typically in environments where heavy equipment is not installed . Composite Materials and Fiberglass: Used in specialized scenarios requiring insulation, corrosion resistance, or lightweight construction. These materials are less common for heavy-duty server racks due to lower structural strength .

Practical Considerations

• Main Frame: 1.5mm cold-rolled steel with galvanization is ideal for high-load cabinets, ensuring stability and long-term durability .
• Front/Rear Doors & Side Panels: 1.2mm cold-rolled steel balances rigidity and weight, allowing for heat dissipation holes and lock mechanisms .
• Internal Mounting Trays: 1.0mm galvanized steel can support individual equipment up to 150kg .
• Dust-Proof Frames: 0.8mm stainless steel ensures rust-proof and durable support for removable dust filters .

Benefits of Thickened Materials

1. Load-Bearing Capacity: Supports heavy servers, switches, and routers, often exceeding 800–1000kg for freestanding cabinets .
2. Durability: Thick steel provides impact resistance and long-term structural stability.
3. Heat Dissipation: Metal thickness allows integration of perforated panels or ventilation systems without compromising strength .
4. Corrosion Resistance: Galvanized or stainless steel coatings prevent rust in humid or outdoor environments .

Conclusion

For high-performance network cabinets, cold-rolled steel (1.2–1.5mm) for main frames and panels, combined with stainless steel (0.8–1.0mm) for dust-proof or corrosion-sensitive components, is the most common and reliable choice. Aluminum or composite materials are suitable for lighter loads or specialized environments, but thickened steel remains the standard for durable, high-load, and long-lasting network enclosures .
