Frequently Asked Questions
IP66 means the enclosure is fully protected against dust and resistant to powerful water jets, making it suitable for outdoor and industrial environments.
Yes, IP66 mild steel enclosures are suitable for outdoor use when properly installed. The powder-coated finish provides protection against environmental exposure, although stainless steel may be preferred for highly corrosive environments.
Mild steel enclosures are more cost-effective and suitable for general industrial use. Stainless steel offers higher corrosion resistance and is better suited to washdown, chemical, or coastal environments.
Mounting plates are available and typically supplied loose with the enclosure, allowing for flexible installation depending on your setup.
