„God is in the details” – Ludwig Mies van der Rohe

Details make the differance!

One of the important advantages of the Lightweight Steel Frame (LSF/LGS/LGSF) structure is its versatility.

Practically, this means that there are numerous options for constructing the building details by combining U and C profiles to meet the requirements of strength, stability, as well as various combinations of materials that can be used to address energy efficiency, acoustic properties, installation and handling, aesthetic preferences, budget considerations, etc.

Correctly resolved details enhance the lifespan of the building, highlight the characteristics of the materials used, and contribute significantly to the overall efficiency of the structure.

Home frame

In essence, it is a modern technology (Lightweight Steel Frame) related to the use of a high-performance load-bearing structure, composed of cold-processed galvanized steel profiles with thin walls, very lightweight and made exclusively from high-quality structural steel, designed, calculated, constructed, and assembled according to standards and regulations, it exhibits remarkable strength against various types of stresses.

conformari standard

Standard conformities

• The weight of the frame structure ranges between 40-60kg/mp;

• Maximum height of the building P+2E (H) – 12-15 m;
• Height between two floors (h) – 3,6-4 m;
• Standard opening between two walls (d) – 6 m;
• Standard opening size for the window/door frame. (l) – 4 m;
• Bracket (c) – 1,2 m (floor structure only);
• Roof pitch (u) – 5 – 90 grade;

One of the major advantages of frame constructions is that they are lightweight, resulting in foundations being reduced by up to 40% compared to the foundation of a traditionally built house with masonry and reinforced concrete.

Walls and Facades

The composition of interior/exterior walls meets multiple requirements simultaneously (thermal insulation, sound insulation, strength, energy efficiency), with the condition that everything needs to be addressed in the design and modeling phase.

3.1.4 Detaliu montaj tamplarie PVC cu montaj pe bride la fata termoizolatiei


The frame structure (LSF) can easily accommodate various types of windows and doors, regardless of the material they are made of: solid wood, laminated wood, engineered wood, PVC, aluminum, steel, or combinations thereof.

We recommend a few minimum conditions that we always take into account::
• windows should have triple glazing (triple-pane);
• the U-value of the windows, together with the glass, should be less than 1;
• installation of the windows should be done using brackets, unless specified otherwise by the window manufacturer;

Intermediate Floors and Stairs

The compositions of intermediate floors can meet various types of requirements (structural, acoustic, thermal insulation, etc.) depending on the specific project requirements.

8.5.3 Terasa detaliu cu aticul in continuarea profilelor de fatada 1


From a structural standpoint, terraces are very similar to intermediate floors, and depending on the openings and loads, C/U200 or C/U300 profiles can be used with single or double arrangements (back-to-back).

There are two ways to arrange the terrace floor within the frame structure:
• with interrupted studs;
• with continuous wall studs;

Sloped Roofs

This type of roofing is perhaps the most well-known and commonly used for all types of constructions, especially residential ones. The frame structure (LSF) allows for both traditional and modern solutions for such roof configurations.


Our technology in frame structure construction

U/C profiles with a thickness of 1.5 mm and a height of 160, 200, 300 mm;
Profiles are fixed with 8 screws per node;
The rafter insulation is done with cellulose fibers or mineral wool;
All types of roof coverings can be used in a ventilated or non-ventilated system;
Rafters can be configured in various ways: with a straight slope, with a sloping slope (concave or convex);
For natural lighting of spaces, skylights, attic windows, or dormers made of the frame structure can be used;
