Hot dip galvanized steel grating tolerance
The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm.
