Currently, metal structures are the most popular elements in construction. Metal structures are used in the process of erecting industrial workshops, storage facilities, office centers, etc. D. It should be noted that the manufacture of metal structures involves the execution of the parts of the “frame” of the house, as well as the main elements, for example, if we are talking about the construction of galleries and bridges. Given the quality of the use of metal structures, certain types of this product may vary.
First of all, light -type metal structures are actively used in the process of building low -rise structures of non -residential direction, that is, warehouses, hangars, etc. D. In the process of erecting such buildings that have a small number of storeys and area, it is the rapidly vegetable metal structures that are such an option that is ideal in cost. The manufacturing process of such metal structures is not very costly, respectively, the final value of the object is very low. If we are talking about the construction of more bulky structures, then t. n. heavy metal structures. Such products are relevant for industrial construction.
Currently, industrial enterprises are made steel metal structures, the basis of which are light alloys and aluminum. Materials for metal structures are sheet and profiled metals. Light -type metal structures began to be actively used in the construction sector from only the twentieth century. Before that, metal structures were based on an alloy of cast iron. For example, during the construction of the St. Isaac’s Cathedral in St. Petersburg, elements of just such a performance were used.
