FAQ

Steel Frame Building Questions

What is a pre-engineered steel frame building?

A pre-engineered steel frame building is a structural steel enclosure where the primary framing (columns, rafters, and purlins) is custom-designed and fabricated for your specific dimensions and loading requirements. Unlike stick-built construction, all structural members are manufactured in a controlled factory environment, then assembled on-site or shipped as a complete pre-assembled unit.

What sizes are available for steel frame equipment buildings?

Steel frame buildings can be engineered to virtually any dimension. Common widths range from 12 ft to 100+ ft clear span. Length is modular — buildings are designed in bays (typically 20–25 ft) and can be extended indefinitely. Eave heights from 10 ft to 30+ ft are common. We build the structure to match your equipment footprint, not the other way around.

Can steel frame buildings be relocated?

Yes. Buildings designed on skid or base-frame foundations can be crane-lifted and transported to a new site. Permanent slab-anchored buildings can also be disassembled and re-erected at a new location, though this is more labor-intensive. We recommend discussing relocation requirements at the design stage so the structural connections are designed for easy disassembly.

What is required for the foundation?

For permanent installations, a concrete slab with embedded anchor bolts is standard. For relocatable buildings, we fabricate a structural steel base frame (skid) that the building sits and ships on — requiring only a level, compacted gravel or concrete pad on-site. We provide anchor bolt layouts and base frame drawings as part of the project package.

How long does it take to build and deliver a steel frame building?

Typical lead times are 8–14 weeks from design approval to delivery, depending on size and complexity. Simple standard buildings can move faster. We provide a firm lead time at the time of order. Rush production scheduling is available for time-critical projects.

What permits are required for a steel frame equipment building?

Permit requirements vary by jurisdiction, project type, and whether the building is considered permanent or temporary/portable. We provide a complete engineering package including stamped structural drawings to support building permit applications. For classified location (hazardous area) buildings, we provide the documentation package required by the Authority Having Jurisdiction (AHJ).

What HVAC options are available?

We integrate a range of HVAC solutions: electric unit heaters for freeze protection, rooftop or wall-mounted split AC/heat pump systems for year-round climate control, explosion-proof HVAC units for classified locations, ventilation fans with motorized dampers, and positive-pressure fresh air systems for purge and pressurize applications. Equipment is sized to your building volume and heat load.
