New, innovative and environmentally friendly solutions are being introduced to the construction sector through technological innovations. Nowadays, engineers are increasingly forced to replace heavy hot-rolled parts with thin-walled cold-formed parts in order to reduce material consumption. Reducing the weight of the structure has a number of advantages, including reducing the amount of material used and the costs of transporting and assembling the structure. This type of building can also use any readily available cladding material, such as sheet metal decking, cassette facade cladding, vertical and horizontal sandwich panels, etc.
Buildings made of cold-formed steel have several special components that need to be designed correctly. Class 4 sections with limited load capacity are often asymmetrical or monosymmetrical and are made of steel strips with a thickness of up to 6 mm and a limited width. The design possibilities of a building are therefore limited by the capacity of the section to support its weight.
On the other hand, structures with greater heights or spans usually have double sections. The capacity of the section to support more weight is increased by this approach, which also greatly simplifies the design of joints. Two columns and a roof rafter form the simplest load-bearing frame structures.
Applications for structures made of cold-formed steel are often the same as for buildings made of hot-rolled steel sections. Warehouses, agricultural buildings and workshops are the most typical structures made of cold-formed steel channels.
Buildings with cold-formed structures have the following advantages:
