Installation clearance of steel grating is 10mm and little
adjustment is allowed. Each side of bearing bar's length in
supporting beam where steel grating loads the two ends of flat
steel is at least 25mm.
Installation of steel gratings:Two methods can be used:welding and
using saddle clips.Permanent steel gratings requiring no
dismantling can adopt welding, to be welded onto its supporting
beam;the concrete position is located in the first bearing bar of
each corner for steel grating.Adopting saddle clips will have
advantages of not damaging zinc coat and easy removing.The safest
method is fixing by welding so that steel grating can't fall from
beam due to loosening clips.
Application of Saddle Clips:Saddle clip should be installed in the
four corners of steel grating and must be fastened to the maximum
extent to avoid falling off.At least 4 sets of saddle clips are
required for each steel gratings and the quantity of applying
saddle clips will increase as the length of a steel grating gains.
Type A - composed of a top board with double hook,a holding down
plate with teeth and an M10 (or M8) inner-hexagon-bolt.
Type B - composed of a top board with double hook(where one hook
can draw together two neighboring steel gratings),a holding down
plate with teeth and a M10(or M8) inner-hexagon-bolt.
Type C - composed of a top board with double hook and a M10 (or M8)
hexagon-bolt which can be welded in the supporting structure.
