Walkway Galvanized Serrated Steel Grating Anti Slip Customized
Serrated steel grating is high strength same as plain surface bar
grating, it also has non-slip characteristics, no sharp edges but
smooth serrated top surface, to meet safety and aesthetic
Load Bar (Bearing Bar)
A longitudinal load-carrying member of uniform section spanning
between supports, which can be serrated,
Cross Bar (Transverse Bar)
The connecting bars, made from twisted square bar or round bar,
which extend across the bearing bars, usually perpendicular to
Banding BarA flat bar welded to the end of a grating panel, or along the line
of a cutout, and extending neither above nor below the bearing bar.
The dimension of a grating panel measured parallel to the bearing
The overall dimension of a grating panel, measured perpendicular to
the bearing bars.
Pitch includes the pitch of bearing bar, and the pitch of cross
bar. The pitch of bearing bar also called bearing bar center, it
means the distance center-to-center of the bearing bars. The pitch
of cross bar also called cross bar center, it means the distance
center-to-center of the cross bars.
It means the steel grating panel is not banded.
Toe Plate (Kick Plate)
A flat bar attached against the outer edge of a grating or rear
edge of a tread, and projecting above the top surface of grating or
tread to form a lip or curb.
Span of Grating
The distance between points of grating support, or the direction of
The bar has a cross sectional shape resembling the letter “I”.
Grating which has the top surfaces of the bearing bars or cross
Refers to steel –for example ASTM A6
A plate welded to a stair tread for fixing to a stringer.
A special L-section member serving as the front or leading edge of
a stair tread, or of grating at the head of a stair. The type of
nosing can be checked plate nosing, vertical striped plate nosing,
and perforated plate nosing.
Welding each bar on sides, top and bottom. Welded completely.
The coating, usually paint or hot dip galvanizing which is applied
to the grating.
