Modular Plenum Systems
& Industrial Steel Assemblies
Standardized mission-critical generator plenums and value-engineered large steel assemblies, manufactured in Arizona for projects nationwide.
Two Core Solutions. One Industrial Partner.
RoXteel provides a standardized modular plenum system and value engineered steel assemblies for large industrial applications.

Modular Plenum Systems

Most generator plenums are custom-built for one genset and one site. The RoXteel system is intentionally standardized, the same modular architecture repeats across projects, genset brands, and sites, so erection is fast and predictable instead of a one-off field build.
- Standardized 20-foot modular sections
- Divorced from the genset enclosure, self-supported
- Repeatable across projects, sites, and genset brands
- Built for fast, predictable site erection
Value Engineered
Steel Assemblies

Bring us the assembly, drawing, or problem. RoXteel reviews opportunities around manufacturability, weight, cost, constructability, repeatability, shipping, and installation, then builds the solution.
- Manufacturability
- Cost and weight
