SCR Support Structures for Data Center Generators
Self supported structural steel straddle frames and rail systems for SCR equipment on data center gensets, engineered for new construction and retrofit applications.

What Is an SCR?
SCR, or Selective Catalytic Reduction, is an exhaust aftertreatment system used to reduce nitrogen oxide (NOx) emissions from diesel generators. In an SCR system, diesel exhaust fluid (DEF) is injected into the exhaust stream ahead of a catalyst, where it reacts to convert NOx into nitrogen and water. Large data center gensets may require SCR to meet local air permit and emissions requirements, so SCR emissions control has become a growing consideration for mission-critical standby power.
This section explains the equipment RoXteel’s structure supports. RoXteel does not manufacture the SCR itself.
The SCR Needs Its Own Structure
- SCR equipment is large and heavy.
- It may sit above or alongside the genset.
- The structure must safely carry the load.
- It must fit around the generator and enclosure.
- It must maintain a workable generator yard.
The SCR straddle frame carries the load independently, never relying on the genset enclosure.
The structure fits around the generator, enclosure, and site constraints while keeping the yard workable.

New Build or Retrofit
New Build
Designed into the generator yard from the beginning alongside gensets, enclosures, plenums and related systems.
Retrofit
Designed around existing generators, enclosures and site constraints so SCR support can be added to operating or already constructed generator yards.
The Structure Behind the SCR
RoXteel designs and manufactures the structural steel system supporting the SCR.
Self supported structural frames spanning the genset.
Structural support configurations engineered around equipment and yard geometry.
Designed for applicable IBC and ASCE 7 loading requirements.
Repeatable fabrication, coordinated project schedules and RoXteel project management.
RoXteel does not manufacture, certify or provide the SCR emissions equipment itself.
Built on Proven Straddle Frame Experience
This capability connects directly to RoXteel’s existing generator infrastructure experience.
- Modular plenum straddle bases
- Self supported structures
- Coordination with exhaust systems
- Repeatable manufacturing
- Project specific engineering
- Nationwide project support
RoXteel has experience coordinating plenum structures with preinstalled exhaust systems and understands how exhaust equipment integrates into the generator yard. RoXteel does not manufacture exhaust systems.
RoXteel is ready to work alongside SCR manufacturers and integrators as a Solution Partner.
