N2 - I-girder is one of the most used cold-formed steel sections. This shape is preferred because it has high stiffness under load. However, this section has areas for improvement, such as local buckling and local distortional buckling. Based on this came the innovation of hollow tubular flange girders (HTFG), replacing the conventional plate flange with a hollow tubular flange. The result has been shown to offer significantly higher torsional stiffness when compared to a conventional I-girder of the same height, width, and weight. In addition, failures of conventional I-girders like local buckling can be reduced by replacing the flange from plate to hollow tubular. Against the background of hollow tubular flange girders (HTFG) having better structural behavior than conventional I-girder steel, there is an urgent need for a review of hollow tubular flange girders (HTFG). This review aims to contribute to a better understanding of hollow tubular flange girders (HTFG) and how they can be an alternative to cold-formed steel used in construction. The review was conducted of 7 articles related to hollow tubular flange girder girders (HTFG) and their effect on their structural behavior and citation of 31 similar articles. As a result of the closure, this article concludes that in research on HFTG is very necessary to compare the modified results with conventional I-girders to find out how far the effect of these modifications is; when compared to its fellow hollow tubular flange girders, it should have the same variable limitations, such as weight and thickness or even height of the web.
