Steel is strong and resists extremely well to traction; that’s why you see it anywhere from the Golden Gate Bridge to the Eiffel Tower.
That’s why it’s often used to create the structure of a house – the “bones” that keep it standing; while other, more insulating, materials are used for the walls.
This can be done with either just a few, heavy beams and posts – then it’s called “steel frame”; or with a larger “grid” of much thinner profiles, who work together to create a network structure.
This is called light steel frame; it’s logic is comparable to the traditional wood framing used in the USA and Australia.
Although it resembles the profiles often used for drywall, a LSF profile is thicker and stronger and calculated to bear much larger loads.
These days, more and more light steel frames are pre-fabricated (often robotically!) in a factory. Frames can be produced for entire walls and floors, with openings for windows and doors already built in.
Finishing panels then are easily screwed on both sides of the panels – from fibre concrete to plasterboard – and the result is fast, cheap construction.
Light Steel Frame is Smart
- easy to assemble,
- light, so little foundation is necessary
- can be pre-built in factories
- little or no waste
- works with any kind of finish
Limitations of LSF
- like most “light” building systems, by default it has little sound proofing. This cán be compensated by adding insulation or double skins of plasterboard/fibreboard etc.
- by default, has little thermal insulation or thermall mass, so insulation and mass must be added where necessary
