LSTC technology (lightweight steel thin-walled structures) is a fast-duct-frame construction technology.
The technology is based on the use of a profile from zinc of perforated and non-perforated steel in the base of the building, as well as wall panels on the basis of these profiles (as constituent structures).
This construction technology began to use already in the middle of the 20th century in North America, when there was an active development of the mechanical engineering and metalworking industries. At the same time, an idea and the opportunity to transfer the major construction work to the factory appeared.
At the beginning, after this technology built low-rise houses and commercial buildings no more than 3 floors. In the factories were made low-rise building kits that were delivered and construction sites for assembly work.
Since the assembly could be carried out during any time of the year and in all weather conditions, it was possible to build the building quickly, without the use of heavy special equipment and with low labor inputs.
Therefore, construction has become more economical, precise and more mobile, with the possibility of maintaining a high quality of the object.
This construction technology is based on a multi-layered wall panel – TERMOPANEL.
The thermopanel frame is made of special galvanized steel profile type - thermoprofile -, which has cross-sections, which allows a significant increase in the distance of the hot flow.
Thanks to this thermoprofile feature, the structures built on it completely preserve the heat, reduce the cost of using the building and reduce the load on the networks as a whole. This technology allows buildings to be built even in the northern regions.
The thermoprofile is made of high alloy galvanized 1.0-2.0 mm thick steel, zinc thickness 275 g / m2, class 1 galvanizing.
The steel used for the production of thermoprofile is characterized by a very high density resistance, which allows for the construction of lightweight structures with high bearing capacity.
From the very beginning, thermoprofile is produced according to a certain design. Accordingly, there is a kind of "constructor":
The thermoprofile elements are mounted in the frame of a future wall panel, after which the frame is filled with a basalt heater. Next, the panel is wrapped in a vapor-proof membrane that does not absorb moisture. Then the outside of the panel is applied to the fiber cement hob while two gypsum chip panels are installed inside. As necessary, the panel assembles cable ducts for further installation of electrical wiring.
All materials are ecologically clean, comply with fire safety norms, they have high strength indexes.
Small panel weight (without a façade - 50 kg / m2, with a ventilated facade - 80 kg / m2) gives the opportunity to use a lightweight foundation and carry out construction work on bad bases.
Buildings kits are being built for the construction of low-rise buildings. Together with external wall panels it includes enclosing panels, construction system, doors, windows and the rest, depending on the chosen set.
VTPK technology is an energy efficient building method. The unique properties of lightweight steel structures provide the opportunity to maintain the microclimate throughout the year (in the summer, they are not hot, in the winter they are warm). Houses of such material are safe, refractory, ecological and do not decrease with time.
