MESH : It is the center distance between two adjacent bearing bars and cross bars.
CROSS BAR (CB) : They are positioned transversely across bearing bars and are welded into them at their interaction point to provide lateral restraint. In steel Gratings, these are made of square twisted wire road from low carbon grade steel of SAE1008.
EDGE BINDING OR FRAME BAR (FB) : Bar fixed to the edge of the gratings and flush with the top of bearing bar.

SPAN (S) : Total length between the supports, i.e. the extreme ends of the bearing bars. It is measured parallel to the bearing bar. (Length of the load bearing bar)
WIDTH (W) : It is the overall width of the panel measuring 90° to the load bearing bar.
CUT OUTS : The area of the gratings removed to allow structure, Pipe, Plant, Obstruction or handrail to be fitted in.
