Steel frame modular homes, answered

What is a steel frame modular home?

A home built on a welded structural steel frame instead of a wood floor system, manufactured indoors in Thunder Bay and delivered ready to set. The steel frame gives industrial-grade strength and rigidity for highway transport, with lengths, widths, and exteriors tailored to the site.

Are steel frame modular homes warm enough for Northern Ontario winters?

Yes. Every steel frame model carries R-60 ceiling and R-24 wall insulation, engineered for the Northern Ontario climate, and indoor construction produces a tighter envelope than a weather-exposed site build.

What sizes do steel frame modular homes come in?

The catalogue runs from a studio through 1 bedroom and 2 bedroom models, all finished to a single spec sheet. Lengths and widths are adjustable and exteriors are fully customizable, so the same system scales from a compact studio to a family home.

Are steel frame homes built to the Ontario Building Code?

Yes. Like every ModBox build, steel frame homes are engineered to meet or exceed the Ontario Building Code and are set permanently on a prepared foundation.
