Steel houses in the USA, Australia, New Zealand, as well as Poland?
It was accepted that steel is mainly used in hall and tower buildings. Large girders, large columns are the starting point when one hears about a steel structure.
How can this be used in building a single-family home? Here, we use a construction that is overall much smaller than the structural elements for the hall. I will go further, it is a roll of galvanized sheet, bent cold in the shape of the channel section. These are thin profiles that have the appropriate strength parameters. In cooperation with an architect, you can try bold solutions for large glazed surfaces without worrying about the load-bearing parameters of the structure.
Comparing the strength parameters of materials, steel clearly excels in tensile strength, ie a key factor affecting the load-bearing capacity of structural elements. I note that the construction of a house made of concrete or wood consists of elements with a wide cross-section of approx. 24 cm. This causes in the masonry construction heat bridges resulting from different materials appearing next to each other, namely on a brick a window lintel is based or in a wooden construction a wooden pole adheres to the insulating layer. In the steel structure, we have a situation where the insulation layer connects to the structural element, however, the structural element has a thickness of approx. 1 mm, which means that such a thermal bridge is negligible.
