China Steel Bar Grating Manufacturer & Exporter/Welded Bar
Steel grating/Metal Bar Grating is perfect for factories, buildings. generating plants; in fact
anywhere the ease of movement and safety is required.
With steel grating quick fitting accessories, ease of cleaning,
safety and strength will provide you with the economical answers to
lots of applications.
Because of its robust design and spanning abilities, steel grating
is very strong and safe for the support of floors and elevated
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
Flat Type Bearing Bar
Flat bars can be made from steel strip or slit sheet or from
Serrated Type Bearing Bar
Serrated type grating offers users a slip-free surface. It is
available with most of the standard bearing bars.
"I" Type Bearing Bar
An extruded bearing bar having a cross sectional shape resembling
the letter "I".
Press-locked steel bar grating
Press-locked steel bar grating is often desirable because its
smooth look, clean and excellent support. It exhibits the same
strength, long life and openness as welded grating. Materials
include mild carbon steel and stainless steel. It is also available
in a serrated surface for extra safety.
Spacing range can be custom designed to meet the requirements. This
method of manufactureing is particularly flexible that it allows
for the production of grating with custom bearing bar spacing.
Small quantities can easily be manufactured to suit the precise
needs of most applications.
Mild Carbon Steel:
Mild carbon steel provides an economical, high strength for uses in
most industrial and commercial applications. The load bearing bars
are produced from steel which conforms to the following equivalent
standards: JIS G3101 SS400 or ASTM A36 or equivalent.
Stainless bar grating is a choice for corrosive environments such
as chemical, food and hydro processing areas. It is available in
welded and press locked as well as in many bearing bar sizes. The
most common material is Type 304 (SUS304), however, Type 316
(SUS316) or Type 316L (SUS316L) is also available. 304 stainless
steel is the most popular type contains both chromium and nickel to
provide excellent balance resistance and workability. 316 stainless
steel is better corrosion, pitting resistance and higher strength
at elevated temperatures than 304. 316L is extra low carbon
variation of 316 to avoid carbide precipitation due to welding.
Allowing quicker delivery to customers whom fabricate and galvanize
the grating on their own.
Hot Dip Galvanizing can give a hygienic and clean maintenance free
bright finish. The minimum average hot dip galvanized is coated as
required by Standards AS1650, BS729 and ASTM A123.
