Steel is known as “enviro-metal “is the world’s most recyclable material. It is a natural material, from a chemical point of view its basic constituent is iron, which belongs to one of the most widespread elements of the Earth’s crust, therefore it does not burden the environment with harmful substances.
Ecology and lightweight steel structures may at first seem incompatible, but after a detailed research it turns out different. An ordinary person understands “ecological” architecture as a use of building materials that are found in nature. Brick and concrete do not belong in these selections. Iron is mainly found in oxidized form, in its original form it is found in ore veins. Only materials that can be considered as natural are stone, unburnt brick and wood. However, wood requires further modifications, it must be treated with “natural” chemicals. Nature “mixtures” are required for stone cladding.
