Industrial Steel Fabrication & Modular Assemblies for Projects Nationwide
RoXteel manufactures modular plenum systems and value engineered large industrial steel assemblies in Wittmann, Arizona for mission critical and heavy industrial projects across the United States.
Built in Arizona. Supporting Projects Across the United States.
Two Businesses. One Arizona Manufacturing Base.
RoXteel operates two primary businesses from Wittmann, Arizona: a standardized modular plenum product and a consultative large industrial steel assembly capability.

Modular Plenum Systems
Standardized modular generator plenum systems for mission critical standby power.

Value Engineered Large Industrial Steel Assemblies
Large industrial frames, modules, skids, racks, supports and repeatable structural assemblies.
Industrial Steel Assemblies Across the Industries We Serve
RoXteel manufactures structural steel assemblies for mission critical and heavy industrial markets, built in Arizona and deployed across the United States.

Data Center Infrastructure
Structural steel assemblies for power, cooling, utility and equipment infrastructure, plus the Modular Plenum System for mission critical standby power.

Bitcoin Mining
Container and pod frames, stackable rack structures, cooling equipment supports and electrical skid frames for repeatable mining deployments.

Mining Equipment
Conveyor trusses and supports, crusher and screen structures, chutes, hoppers, modular processing plant frames and equipment support steel.

Gas & Energy

Built Around the Assembly, the Destination & the Delivery Plan
RoXteel considers fabrication, transportation, site access, setting sequence and repeatability together. The build is planned around how the assembly ultimately needs to reach the project.
Smaller structural assemblies can ship efficiently as part of a truckload.
Larger assemblies can be planned around permitted transportation, modular shipment or a project specific transport strategy.
Where the assembly allows, design can work around approximately:
These are planning references, not published manufacturing limits. Final size and transportation strategy depend on the assembly and project.

55 Acres Built for Industrial Scale
RoXteel operates within the All Things Metal industrial ecosystem in Wittmann, Arizona. The campus is built to support large, repeatable industrial steel manufacturing and long term capacity.
