Group of inventions relates to building and can be used at designing and making light-weight metal structures for production, warehouse, civil and other purposes. Spatial-grate structure of covering rests on heads of columns and includes lower and upper ledges, angle braces and spacers connected to each other by node volumetric elements on which girders of the ceiling rest. According to the invention, the lower and the upper ledges parallel to girder of covering are lifted in ridge over heads of columns, neighboring node elements of the lower ledges are connected to each other through rings, in normal to each other planes of those bolt joints with node spatial elements are provided, and neighboring rods of the upper ledges are connected to each other by flanges and rest through those on standpipes installed in planes of angle braces. Method for mounting covering includes assemblage on stand of spatial-grate half-trusses with given inclination, half-trusses are combined to enlarged trusses with length by bearing of covering, those are mounted in pitch, in ridge one forms long link trusses. Technical result is in provision of accelerated removal of atmospheric precipitations from roofing and simplification of cover mounting.
