FIELD: construction industry.
SUBSTANCE: invention refers to construction industry and can be used during erection of metal thin-wall columns in factory-assembled constructions of civic, industrial and public buildings. Metal I-section column consists of two posts connected to each other by means of thin corrugated wall with corrugations located in transverse direction. In the places where big forces appear, wall is made in the form of a flat insert. Corrugated wall is attached to posts with one-side welds. Corrugated wall is attached to flat insert with overlapped welds without stiffeners.
EFFECT: reduction in consumption of materials and manufacturing labour when ensuring stability which corresponds to stability of through columns.
