Self-supporting grating for shelving, shaft cover, footbridge, etc. is held on support profiles of beams via slotted apertures in frame and end profiles, to secure against lifting from below

摘要

The grating is supported on two or more beams (1,2) with projecting support profiles (1.1,1.2). It consists of parallel bars (11). A frame profile is positioned within a grating section destined to be supported on the beams, and/or on the outside of the grating, and parallel to the bars. The profile has apertures (12) with a slot section (12.1), which is pushed over a support profile. Support profiles, an end profile (15,16), and/or the frame profile are formed from rectangular tubing.
