- 03In-house powder coating and production quality checks
Choose with confidence
Find an enclosure type for your environment
Compare enclosure types for indoor and outdoor applications, including exposure to water, dust, ice, or corrosive conditions. Confirm the applicable requirements for your installation and project specifications before selecting an enclosure.
Match the installation
Identify whether the enclosure will be installed indoors or outdoors, and note the exposure conditions and access needs at the site.
Plan the fabrication
Provide drawings, dimensions, material preferences, mounting details, and finish requirements for a practical manufacturing review.
Support repeatable supply
Coordinate engineering review, fabrication, finishing, and inspection through one integrated manufacturing partner.
