Steel Walkway Grating Description
A grating is any regularly spaced collection of essentially
identical, parallel, elongated elements. Gratings usually consist
of a single set of elongated elements, but can consist of two sets,
in which case the second set is usually perpendicular to the first
(as illustrated).When the two sets are perpendicular, this is also
known as a grid or a mesh.
Materials: mild steel or stainless steel.
Surface treatment: untreated, painting or hot dip galvanizing.
Bearing bar specification:20*3 to 100*6
Bearing bar pitch:12.5,15,25,30,40,60mm etc. also be according to clients requirement
