Light Gauge Steel Framing (LGSF / Cold-Formed Steel) and Heavy Structural Steel (Hot-Rolled Sections) are complementary technologies designed for distinct structural load profiles. LGSF utilizes high-tensile galvanized steel (0.80mm–2.00mm) cold-rolled into C-studs and trusses, offering unmatched efficiency for 1 to 4-storey residential homes, partitioned hotels, and roofs with spans up to 12 meters. Heavy Structural Steel utilizes hot-rolled IPE, HEA, and HEB beams (S355JR), essential for industrial warehouses, clear spans up to 60+ meters, and heavy overhead crane loads. SerBuild frequently engineers Hybrid systems combining both technologies for optimal economics.

No. Cold-formed steel profiles lack the section modulus and bending resistance needed for wide clear spans without intermediate columns. Heavy hot-rolled steel portal frames or tubular space trusses must be used for spans over 15–18 meters.
A hybrid system uses heavy hot-rolled steel columns and transfer beams on the ground floor to create massive open spaces or commercial storefronts, paired with lightweight LGS wall and floor cassettes for the upper residential floors.
Light gauge steel is generally faster for residential builds because panels are lightweight and can be lifted by hand or light machinery. Heavy steel requires mobile cranes for every primary frame lift but erects wide industrial spans rapidly.
LGS framing is more economical per square meter for multi-room residential layouts (€95–€180/m²), whereas heavy steel is more economical for high-volume, column-free industrial spaces (€65–€110/m²).
Yes. LGS is calculated under EN 1993-1-3 (Cold-formed members) and Heavy Steel is calculated under EN 1993-1-1 (General rules and rules for buildings).
