The buildings erected in the construction of a light steel skeleton are still a big novelty on the Polish market. However, you can assume that thanks to this innovative technology from New Zealand, and successfully implemented worldwide, skeletal steel houses will become more and more popular.
Steel has enormous potential, especially in the current, growing environmental awareness, the need to save energy and the fast growing construction consistent with the principles of sustainable development. And although the design is only a part of the building, it is worth looking at how it affects the subsequent stages of construction and use of the object.
An incredible advantage of steel constructions is the huge ability of steel to be recycled. It is the most recyclable material in the world because it requires scrap in the production process. The SCS technology itself is additionally very effective in terms of steel consumption. The only wastes are notches for installation holes in the profiles. Completely eliminated the need for waste management on the construction site, for which ready-made elements are delivered, made to measure with millimeter accuracy. The construction elements can easily be used again when changing the way of use. Moving even the entire unwieldy wall is not a problem. Office, exhibition, commercial and production buildings are spaces that are subject to frequent re-arrangement as the destination changes. SCS technology speeds up these changes.
Frame construction is easier to process. And although no one builds thinking about changes, time verifies our decisions and it is worth thinking about when choosing a construction.
Steel has the best weight-to-strength ratio among construction materials, which significantly reduces transport costs. The rigid steel structure, for a building of the same size, is several dozen times lighter than a brick structure. An additional benefit of using a steel frame associated with its weight is the possibility of using lighter foundations.
Building buildings in steel structure also allows to significantly reduce the time of construction works. The use of SCS technology allows building at low temperatures. It is a dry technology, which eliminates the breaks for drying between successive stages of work. In addition, shortening the construction time has a significant impact on its financing.
The type of construction chosen always affects also subsequent stages of works, including assembly of the installation. In SCS technology, it takes place very quickly and cleanly. Profit on man-hours, on materials and high comfort of working conditions are unprecedented advantages of SCS profiles. The wiring of the installation is interwoven with the holes prepared in the factory. In the empty space of the walls, there is no problem of the collision of electric wires with the pipes of other installations. In the event of any failure during operation, removing faults inside the walls, inserting additional electrical or water points is very easy, and also much cheaper and cleaner.
Another important point, or perhaps the most important, which should be carefully analyzed, is the energy efficiency of the building. Steel structures require more attention to insulation work. Steel is a very good heat conductor. Each profile is a thermal bridge. It is necessary, therefore, to insulate the building outside the structure as in a brick building. However, with the planned budget, the same financial means allow for better physical parameters in the house from the steel frame, and even for the application of modern methods of spray insulation that tightly fill the wall space creating a monolith that eliminates the air flow. Such an insulated wall gives comparable parameters to those in passive houses without the need to incur additional costs during construction, and with large profits in the operating costs of the inhabited building.
The finishing of the walls in the steel structure are gypsum boards, which are increasingly replacing traditional internal plasters. It should be remembered that dry plasters were created for skeletal construction. Therefore, the desire to use gypsum cardboard panels, resulting from the ease of their assembly, speaks for the use of a building structure suitable for them – that is, a frame construction.
The SCS system is very precise. The elements delivered to the building accurately represent the design dimensions, which allows to build rooms that maintain the required angles and dimensions. It is also of great importance at the stage of interior finishing.
The modern production line of the SCS system is equipped with numerical control, guaranteeing the precision of execution and the highest quality. Profiles in SCS technology are made in sizes 90 mm and 140 mm. They are made of hot-galvanized structural steel with 275 g / m2 of class 280 and 350, each with a thickness of 0.75 mm, 1 mm and 1.2 mm. Thanks to such diversity, it is possible to produce 12 types of profiles. They are then joined in the factory by means of rivets in various types of frames and trusses of dimensions enabling transport to the construction site. Wall modules, ceiling modules, roof trusses, roof planes are already connected at the construction site by means of screws. The SCS technology can be used to erect buildings up to four storeys, with a maximum wall height of up to 6.0 meters and a ceiling span up to 12.0 meters, or using an additional profile for roof trusses up to 24 meters.
The use of steel constructions brings not only high technical and usable properties, but also interesting and modern aesthetics. The steel skeleton creates the possibility of using the same finishing materials as the traditional technology. Tile, sheet metal, flat roofs with green gardens, wood, plaster, clinker brick, stone – all available materials are a perfect complement to the steel structure. In addition, however, it justifies the use of many unused modern facade materials such as aluminum façade systems in the housing industry, giving room for architects using modern stylistics. Functional, aesthetic and qualitative properties perfectly harmonize here, creating a very interesting alternative to traditional structural systems.
