Steel Plate
- IP Rating: IP55-IP65
- Advantages: Robust, cost-effective
- Limitation: Risk of corrosion
- Typical industries: Industry, building installations
Stainless Steel (AISI 304/316)
- IP Rating: IP54-IP69K
- Advantages: Hygienic, corrosion-resistant, very durable
- Limitation: Higher cost
- Typical industries: Food, pharmaceutical, offshore
Aluminium
- IP Rating: IP65
- Advantages: Lightweight, good EMC shielding
- Limitation: Lower mechanical strength
- Typical industries: Energy, transport
Plastic
- IP Rating: IP65-IP69K
- Advantages: Lightweight, insulating, low-cost
- Typical industries: Building, telecom
Comparison Table
The choice of material for your enclosure affects both lifespan, protection and cost. The table below provides an overview of the most common materials, their IP rating, key benefits and limitations – as well as typical industries where they are used.
| Material | IP class | Advantages | Limitations | Typical industries |
|---|---|---|---|---|
| Steel Plate | IP55-IP65 | Robust, cost-effective | Risk of corrosion | Industry, building |
| Stainless Steel | IP65-IP69K | Hygienic, corrosion-resistant | Higher cost | Food, pharmaceutical, offshore |
| Aluminium | IP65 | Lightweight, good EMC shielding | Lower mechanical strength | Offshore, energy |
| Plastic | IP65-IP69K | Lightweight, insulating, low-cost | Limited durability | Building, telecom |
Summary
- Steel Plate is the standard choice in many industrial environments due to its strength and price, but requires protection against corrosion.
- Stainless Steel steel is the best choice for hygienic and corrosive environments, such as food and pharmaceuticals.
- Aluminium used where low weight and EMC shielding are important, e.g. offshore and energy.
- Plastic is a good alternative for lower cost requirements and electrical insulation, but is best suited for lighter applications.
