With Twisted Steel Bar 6*6 5*5 8* Hot Dipped Galvanized Steel
Grating for Platform
Hot Dipped Galvanized Steel Grating is the product in accordance with customers
requirements that is lined by load flat steel and horizontal rod
alternately in a certain space, welded into primary plate in the
high voltage resistance welding machine, then through the
deep-processing of such working procedures as cutting, slitting,
tapping, bordure, etc.
Steel grating plate, also known as steel grating, grille plate, is
flat steel in accordance with a certain
spacing and cross bar arrangement, and welded into a middle with a
square grid of a steel products, mainly used to do ditch cover Plate, steel platform plate, steel ladder of the
step board. The bar is generally made of twisted square steel.
Twisted steel bars are the steel bars which comes with the right
combination of Strength & Flexibility. This elongation helps to
protect any construction structure.The mechanical interlock between steel and concrete is critical in
reinforced concrete. Early concrete reinforcing was sometimes
smooth and square. This shape did not create much friction to make
a solid interlock. One solution to this problem was to twist the
bar like a corkscrew with creates many teeth for a strong
mechanical lock. The primary drawback to doing this is that the
twisting causes the steel to work harden and become more brittle.

Anchor – A device by which grating is attached to its supports.
Band – A flat bar welded to the end of a grating panel, or along the
side of a cutout, and extending neither above nor below the bearing
Load Carrying Band: A band used to transfer load between bearing
Trim Band: A band which carries no load, used primarily for
appearance and closing open ends.
Bearing Bars – Load carrying main elements made from steel, aluminum, or
stainless steel, extending in the direction of the grating span.
Bearing Bar Centers – The distance center-to-center of the bearing bars.
Carriers – Flats or angles which are welded to the grating panel and nosing
of a stair tread and are bolted to a stair stringer to support the
Clear Opening – The distance between faces of bearing bars in rectangular
gratings, or between a bent connecting bar and a bearing bar in a
Cross Bars – The connecting bars which extend across the bearing bars,
usually perpendicular to them. They may be bent into a corrugated
or sinuous pattern and, where they intersect the bearing bars, are
welded, forged or mechanically locked to them.
Cross Bar Centers – The distance center-to-center of the cross bars.
Curved Cut – A cutout following a curved pattern.
Advantage of With Twisted Steel Bar 6*6 5*5 8* Hot Dipped
Galvanized Steel Grating for Platform
Aesthetic outlook: Simple lines and silver appearance meeting the modern trend.
The best drainage: Leakage area of 83.3 percent, more than twice of cast iron
Hot - dip galvanized treatment: Good rust-proof property, maintenance-free replacement. as BS EN
ISO 1461-2009 GB/T13912,ASTM(A123),BS729
Anti-theft design: The cover and the frame is joint with hinge offering security,
safety and open convenience.(use round bar or bolt&nut with
Savings investments: Large-span. Less lost for heavy load compared with cast iron
products. Cost can be saved for the risk of being stolen or
crushing one if cast iron is uses.
High strength: The strength and the toughness are much higher than cast iron. Can
be used for terminals, airport and other large-span and heavy
