The full background on technology, regulation and design in one place: from the material and the machines through engineering, building physics and fire safety to certification and the building procedure. Articles move on from here into the narrower knowledge bases.
LGS (Light Gauge Steel): a load-bearing structure of cold-formed, thin-walled, galvanised steel profiles, made by a production line from a machine program.
The topics
Section titled “The topics”| Topic | What it covers |
|---|---|
| LGS fundamentals and materials | What a thin-walled steel frame is made of and how: steel, coating, sections, and how it behaves differently from hot-rolled steel or timber. |
| Manufacturing and machines | How a coil becomes a frame member: roll forming, what the machine needs from the designer, and site frame, panel or module. |
| FRAMECAD system | FRAMECAD offers a closed chain: design software, machine control, production management and a machine range in one system. |
| LGS structural design | How a thin-walled steel frame is engineered: why stability governs, how wall, floor and bracing work, and why connections decide quality. |
| Actions and Eurocode | Where the actions come from and in what system we design: the Eurocodes, the national annex, and what changes when designing abroad. |
| Hot-rolled steel and mixed structures | When thin-walled steel needs hot-rolled steelwork alongside it, how the two work together, and what to know about welding and composite floors. |
| Building physics and build-ups | How a frame becomes a well-performing wall, floor and roof: insulation, thermal bridges, vapour control, airtightness, sound insulation. |
| Foundations and geotechnics | A light structure puts little load on the foundation, so the foundation is often simpler and cheaper — but not automatically. |
| Applications and operation | What the technology is and is not good for, how it goes up on site, what to check and when, and what happens to the building over decades. |
| Fire safety and fire resistance | This topic connects two things: what physically happens to a thin-walled steel structure in a fire, and what Hungarian regulation asks for. |
| Construction products and certification | This topic is about what a construction product’s paperwork verifies, who may issue it, and where its limits are. |
| Building procedure and design stages | What permit or notification a building needs, which design stages follow, and who takes part with which licence. The rules changed in 2023–24. |
| General design and BIM | How a complete design package comes together: what general design is, which disciplines work together, where responsibility ends, what BIM adds. |
| Service: general design | One contract, one responsible party, every discipline — from the needs assessment to a BIM model built for the contractor. |
| Service: structural design | Steel, light gauge steel and timber. From permit design through detailed design to shop drawings, from houses to shopping centres. |
| Service: LGS shop design | A buildable shop design from finished architectural or structural drawings, with the machine program and, if needed, supervision of trial production. |
| Service: choosing a service | This knowledge base describes how we work: what each service covers, what input it needs, what we hand over, and what it costs. |
| Service: plan review | If the drawings you were given look wrong, it is cheaper to have them checked now than to meet the problem on site. |
