Metal grating is extremely versatile and can be used in a wide range of applications. Our metal gratings are manufactured from a special fully-killed steel that meets the requirements of good weldability and high load-bearing capacity.

BEARING BARS: Equally rolled flat bar to bear the main load
CROSS BARS: The erung squre steel ( also called twisted steel ) or round bar which is orthogonalized with the bearing flat bars, the cross section shall not be less than 20mm2.
END BAR: Finishing bar of same section as the bearing bar welded across the ends of the bearing bars also around cutouts and notches where these occur.

The bars used to secure the position of the bearing bars are commonly designated as the cross bars. Cross bar profiles vary according to the method of assembly and material selected. As with bearing bars, cross bar spacing is measured as "on center" spacing. The customary cross bar spacing is 4" on center. On special order, 2" on center and other special spacings are also available.
