PL This paper presents the analysis of steel market and its future prospects, as well as discusses the possible usage of thin-walled cold-formed steel (TWCFS) elements strengthened with CFRP composites. Economic analysis was carried out based on literature, professional media and market trends review. A reliability analysis was carried out for TWCFS elements strengthened with CFRP on the basis of laboratory and numerical tests and selected examples from the existing literature. On the basis of the above analyses, two main conclusions were drawn. Firstly, amidst increasing global demand for steel, the vulnerability of the global steel market to distortions and the rising costs of steel production, it will be beneficial for companies to reduce their demand for steel. Secondly, one possible way of reducing steel consumption in construction industry may be the usage of TWCFS elements strengthened with CFRP composites on the wider scale.
