What are insulated steel structure buildings?
Schwarzmann insulated steel structure buildings are single- or multi-story constructions with a steel framework, insulated using panel sheets. The main advantages include the design flexibility offered by steel and a faster construction time compared to traditional building methods.
Insulated steel structure building – the right choice for your business premises (Prit Insulated Steel Stricture)
A steel structure building is an economical, flexible, and long-term solution for meeting your company’s spatial needs. It is economical due to its cost-effectiveness and faster construction compared to traditional methods; flexible because it is custom-designed to your specific specifications; and long-term because the steel is protected with hot-dip galvanization, ensuring a long lifespan.
Advantages of Schwarzmann insulated steel structure buildings
At Schwarzmann, we take an individualized approach and provide comprehensive support throughout the project to ensure the building is custom-made and completed on time. The exterior design is tailored to your preferences in collaboration with your architect. The final price is fixed based on the agreed-upon-design specifications, equipment, and the anticipated scope of work.

Features of Insulated Steel Structure Buildings
Steel Structure
Galvanized steel structure of an insulated steel building.
For office spaces or other functional areas, multi-story designs are possible with steel-structured buildings. The load-bearing capacity of each floor is adjusted according to its intended use. There are two construction methods available: one uses HI-bond sheeting, onto which traditional concrete floors are installed, while a simpler option involves the use of OSB boards.
We manufacture insulated steel buildings in various configurations:
- Single-pitch roofs.
- Gamble roofs and multi-span buildings
- Buildings with a parapet or flat roof
The minimum roof slopes range from 6° for roofs with panel coverings to 2° for flat roofs with Sika roofing systems. If different requirements are specified, a steeper slope can be applied.
Foundations
The steel structure is anchored to a concrete foundation using chemical or embedded anchors to accommodate higher pull-out forces. Typically, linear or spot concrete foundations are used, but it’s also possible to anchor directly onto a concrete slab if it is thick enough to allow for the required anchoring depth.
Foundation of an insulated steel building with embedded anchors
Due to the lighter weight of the steel structure, the foundations are generally smaller compared to concrete buildings—an advantage, especially on less load-bearing soils. Smaller foundations also reduce costs for this phase of construction. As part of the design of the steel section, we can also take over the design of concrete foundations.
Roofing
The walls of Schwarzmann insulated steel buildings are clad with thermally insulated wall panels, or, for unheated buildings, non-insulated trapezoidal sheet metal. Wall panels can be installed horizontally or vertically, and the substructure is adjusted accordingly. In both cases, fastening screws are not visible.
Insulated panels mounted horizontally on the walls of the building.
Insulated panels mounted vertically on the walls of the building
Roof panels are fastened exclusively with SFS screws, which prevent leaks caused by panel settling (no future tightening of screws is required). The slope of the roof primarily depends on the roofing material, with the manufacturer specifying the minimum slope to ensure proper sealing. For panel roofing, this is typically 6°, and for flat roofs with the Sika system, 2°. If different requirements are specified, the slope can be increased. A parapet can be constructed for both roofing systems, giving the building the appearance of a flat roof by concealing the internal slopes with raised wall panels.

All roof and wall joints and finishes are treated with cover trims in the color of the panels. Trims, snow guards, and gutters are made from galvanized sheet metal up to 0.8 mm thick. Standard finishes are predetermined based on internal technical guidelines.
We use only high-quality roofing materials from reputable manufacturers like Trimo, Brucha, Kingspan, ArcelorMittal, Roma, and Sika. The insulation cores in the panels are made of either polyurethane foam (PIR) or mineral wool. The Sika flat roof system uses extruded polystyrene (XPS) or mineral wool. Polyurethane foam offers superior insulation, while mineral wool, though slightly less insulating, provides better fire resistance. A variety of insulation options are available, with thicknesses of up to 200 mm.
Equipment
In addition to assembling the steel structure and covering it, we also offer a range of external building fixtures. Our selection includes pedestrian doors, large industrial sectional doors, PVC or aluminum windows, glass facades, and roof domes. Additional equipment can be provided as per agreement.

FAQ – Frequently Asked Questions
-
What is the price of a Schwarzmann insulated steel building per square meter?
The price per square meter depends on the area and shape of the building, the type and slope of the roof, the roofing, equipment, etc. For each inquiry, we calculate the most economical price based on the building’s specifications and advise you on the best options.
-
What are the standard dimensions of Schwarzmann buildings?
Each building is designed and manufactured to your specifications. We do not offer standard pre-designed buildings.
-
What are the dimensions of the smallest building you offer?
The smallest insulated steel building we offer has a minimum area of 300 m².
-
What is the delivery time?
Delivery times vary based on the order, usually up to 120 days. The schedule depends on obtaining the necessary building permits.
-
What is the warranty for the building?
We offer a 10-year warranty for corrosion resistance of the structure, a 7-year warranty for the technical properties of the panels, and a 2-year general warranty on the building.
-
Can an insulated steel building be relocated to a new location over time?
If the columns are embedded in a concrete slab and parapet (which is common for these buildings), relocation is not possible. These buildings are designed for permanent installation.
