SI-beams are used as roof beams in heated and unheated buildings with spans of 18–33 m, public buildings (children’s schools, sports and event halls), etc. The slope of the upper faces is from 1:33 (3%) to 1:20 (5%). The beams are used together with reinforced concrete or steel purlins, hollow-core or ribbed slabs. I-section is typical and most rational for prestressed beams. The fire resistance of such I-beams equals to 60 minutes. To run various kinds of service lines, this type of beams can be provided with holes.
Beams are connected to columns through anchors. Beams are mounted on anchors released from columns and are tightened with nuts. Before mounting the beams, in order to prevent the destruction of the edges, elastomer support pads are installed in the places where the beams rest.
