Building extensions
in LGS technology
Light steel structures (LGS, LSF) as the ideal solution for extensions on existing buildings — penthouses and additional floors.
The low weight of profiles allows for easy installation by the client and finishing using the owner-builder method.
Superstructures
in light
steel construction
Light steel frame structures (LGS, LSF) offered by BWB STEEL Systems are widely used as supplementary structures, in particular as extensions on top of existing buildings.
The light steel construction system (LGS) is the ideal solution for extensions on top of existing buildings, such as penthouses. Where the weight of the extension is of key importance, light steel construction elements provide the optimal, comprehensive and fast solution.
Due to their low weight, the profiles we supply can be easily installed by the client according to the provided instructions, enabling finishing using the owner-builder method. Every such structure retains full flexibility in the choice of finishing materials.
Advantages of steel
frame construction
LGS frame construction offers measurable benefits over traditional building methods — from weight, through construction pace, to finishing flexibility.
Lower wall weight
A light steel profile structure puts significantly less load on the foundation and ground, reducing earthworks costs.
Fast construction pace
Factory prefabrication and profile precision can reduce on-site assembly time several times over.
No seasonal limitations
Installation possible all year round — no winter breaks, no wet work, no technological windows.
Slim wall section
A slimmer wall means extra usable floor area — particularly important for commercial and residential buildings.
Standards met
Fire resistance up to REI 120, acoustic and thermal insulation in accordance with current standards and regulations.
Cooperation process
The first step is design, allowing project feasibility to be assessed at an early stage. The next phase is production of light steel elements at our facility, followed by delivery and assembly.
Design
- Comprehensive software for designing buildings in light steel construction (LGS) technology.
- The designer creates structural frames based on a new or client-supplied design.
- A wide selection of libraries and stud spacing adjusted to the chosen cladding materials.
Production
- Our machinery park enables production of light steel construction up to 1.6 mm thick, cold-formed.
- Precise, fast and reliable delivery: single- and multi-family buildings, commercial facilities, modular structures, halls and curtain walls.
Assembly
- Option 1: ready-made steel frames with studs, jambs, lintels and sills assembled in the factory — saves time and labour on site.
- Option 2: unassembled steel profiles in packages with all fasteners. Each profile carefully labelled and numbered.
