Steel Grating for stairs, galvanized steel grating
Metal bar grating can be defined as a series of metal bars positioned vertically,
placed an equal distance apart and joined by cross members to form
a rectangular or reticuline pattern. Typically manufactured from
mild carbon steel, 6000 series aluminum and 300 series stainless
steels, bar gratings are also available in specialty metal alloys
to suit nearly any application
The vertically positioned bars are designated as the bearing bars.
These bars range in size from 3/4"x1/8" for light pedestrian
traffic to 7"x1/2" for extreme vehicular loads. Typically, the
spacing of the bearing bars is indicated in sixteenths of an inch,
measured from the center of one bar to the center of the adjacent
bar. This center-to-center or "on center" spacing ranges from 7/16"
to 19/16"(1-3/16") on standard grating products. Standard gratings
are also available with wider spacings providing even greater open
area, but should not be specified without consulting the
manufacturer. Heavy Duty grating products are commonly manufactured
with bearing bar spacings ranging from 15/16" to 38/16"(2-3/8") on
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.
Galvanized steel grating is an ideal product for wet, slippery situation where corrosion
resistance is vital. They are hot dipped galvanized in the
galvanizing bath. The galvanizing bath has got 7 tank surface
cleaning process, the purity of the zinc used for hot dipped
galvanizing shall be 99.95% pure. The galvanized coating shall be
as per IS-3202/IS–4759/IS–2629/IS–2633/IS–6745, ASTM–A-123 or
equivalent to international standards. The appearance of its
surface is plain or serrated.
Galvanized steel grating is made from mild steel or aluminum formed
by a special mechanically press-locked process that eliminates any
welding therefore avoiding any weld stress problems that may occur
with other designs.
Surface Treatment: hot-dipped galvanized
* Long service life
* Excellent load bearing capabilities.
* Ventilation of air, light, sound.
* Dont collect liquid and debris.
* Wide range of open areas.
* Can be purchased in stock sizes or custom fabricated to meet the
* Galvanized steel grating has an unmatched surface. It is also a
permanent replacement for slippery serrated and plain grating.
* It's available in many different styles and spacing options to
meet a variety of needs and applications.
* High strength: the strength and the toughness are much higher
than cast iron. It can be used for terminals, airport, other
large-span and heavy loading condition.
*Anti-theft design: the cover and the frame is joint with hinge
offering security, safety and open convenience.
Galvanized steel grating is widely used in most general industrial
plants as well as commercial buildings, it has wide applications as
walkways, platforms, safety barriers, drainage covers and
ventilation grates. It is also ideal for use as mezzanine decking
since it supports the same loads as comparable solid flooring. More
than that, its cost saving openness maximizes the circulation of
air, light, heat, water and sound, while promoting cleanliness.
