How this system works
The house uses a metal structure. Steel framing uses lightweight profiles to form frames; other systems use larger steel sections. These should not be confused: loads, joints and enclosure are calculated for each proposal.
The frame is completed with boards or coverings, insulation and protective layers. Comfort depends on facades, roof and junction details; a steel skeleton alone is not a finished house.
How it is built, step by step
- Calculate members and connections and coordinate service routes.
- Prepare foundations and the anchors specified in the design.
- Assemble frames and verify connections and stability.
- Complete protection, insulation, coverings, services and finishes.
Advantages
- Profiles can be prepared to specified dimensions and organised for dry assembly.
- The structure can combine with different facade and layout solutions.
- Components and joints can be coordinated precisely when the design is well defined.
Drawbacks and how to address them
- Thermal bridges must be addressed: insulation needs to account for the metal elements.
- Corrosion and fire protection must be specified for the conditions and design.
- Construction requires a company familiar with the system and all its enclosure components.
When it might suit you
It may be a good option for a coordinated metal-structure design with insulation and protection specified from the outset.
What the quote should include
Compare the same scope and performance. The structural material alone does not determine which offer is better.
- Design, ground assessment and foundations.
- Structure, roof and complete facade build-up.
- Insulation, windows and solutions for water, noise and fire.
- Services, finishes, transport and assembly where applicable.
- Schedule, taxes, exclusions and responsibility for each phase.
