INSTRUMENT CASES FOR FIELD EQUIPMENT PROTECTION
Serrmi manufactures steel and aluminum instrument cases, pole-mount cases, and custom equipment enclosures for rail, transit, and industrial applications. Built for durable field protection in locations where space, access, and equipment layout must be carefully managed, each case can be configured around project requirements, mounting needs, internal layouts, and long-term operating conditions. From compact field cases to custom enclosure designs, Serrmi delivers dependable case solutions with the fabrication flexibility required for complex infrastructure projects.
Standard Instrument Cases
Instrument cases are available in steel or aluminum construction and can be built in standard or modified sizes to meet project requirements. Common options include powder-coated finishes, hardware upgrades, conduit knockouts, relay bars, cable risers, aerial outlets, lighting, insulation, and other field-focused modifications.
Pole-Mount Cases
Pole-mount cases provide a durable enclosure option for equipment installed in pole-mounted applications. These cases can include mounting brackets, secure access, weather-resistant construction, and configurable interiors to support electrical, communication, and signal-related equipment in outdoor environments.
Custom Equipment Cases
For projects with unique equipment layouts or wiring needs, Serrmi can build custom cases around the required functionality. Custom options can include shelving, mounting brackets, server racks, insulation, internal lighting, ventilation, and project-specific layouts designed to organize and protect sensitive components.
Built Around Field Requirements
Each case can be configured around the environment, equipment, access needs, and installation method. Material selection, finish options, security features, interior organization, mounting style, and size requirements can all be adjusted to support reliable long-term performance in the field.
