Q235 Welded Steel Grating For Road Seepage
Hot dip galvanized grating for road seepage Welded Steel Grating
Welded Steel Grating Introduction:
Ditch cover plate is made of steel grid plate. There are many types
available to suit different span loads and requirements.
Widely used in municipal roads, garden facilities, residential
areas, schools, stadiums and other different places.
According to the use of different occasions, different
specifications of trench (well) cover plate, the surface can be hot
dip zinc, cold galvanized (electroplating) or no treatment.
Ditch cover plate is mainly used in some factories and high-grade
residential areas, which is mainly because the cement trench cover
is often crushed, and the road surface is also damaged.
Therefore, the trench cover plate made of steel grid plate is
suitable for different load loads.
Welded Steel Grating Specifications:
|Bearing Bars:||Load carrying main element.|
|Bearing Bars Spacing:||Measure from center-to-center of the bearing bars in 1/16″
increments. Standard spacing for industrial flooring is
19/16″(1-3/16″) on center. Other popular spacings are 15/16″,
11/16″, 1/2″, and 7/16″ on center.|
|Bearing Bars Depth:||Ranges from 3/4″ to 7″ depending on anticipated loads.|
|Bearing Bars Thickness:||Ranges from 1/8″ to 1/2″ depending on anticipated loads.|
|Cross Bars:||Used to Secure the position of bearing bars.|
|Cross Bar Spacing:||Measured from center-to-center of cross bars in 1″ increments.
Standard spacing is 4″ or 2″ on center.|
A, flat steel: the material is Q235 or stainless steel, there are
ordinary plane type, anti-skid tooth type and section I type, the
usual specifications are 20*5, 25*5, 30*3, 32*5, 40*5, 40*3, 50*5,
65*5, 100*8, 100*10, etc.
B, bar: material and flat steel, the use of twisted square steel,
it is made of the disk by square horizontal drawing and twisted,
its common specifications are 5*5, 6*6, 8*8, etc.
C, through the above flat steel and bar can be summarized as the
common specifications of steel grid plate: 303/30/100, 325/30/100
and so on.
Method for marking galvanized steel grates
(1) hot dip galvanized steel grid plate flat center spacing:
according to the series to distinguish: Series 1 is 30mm;
Series 2 is 40mm;
Series 3 is 60mm.
(2) hot dip galvanized steel grid bar center spacing: series 1 is
100mm, series 2 is 50mm.
Other specifications can be customized.
(3) hot dip galvanized steel plate flat steel: the material is
Q235B or stainless steel, with ordinary plane type, anti-skid tooth
type and section I type.
The common specifications of galvanized steel grid platform are
20*5, 25*5, 25*3, 32*5, 30*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8,
(4) hot dip galvanized steel grating bar: round steel, twisted
square steel, square steel or hexagonal steel made of Q235B or 304
Twisted square steel is made by drawing and twisting the square
die, and its common specifications are 5*5, 6*6, 8*8mm, etc.
Welded Steel Grating Application:
The use of steel grid plate design and manufacture, widely used in
urban roads, squares, gardens, wharves, airports, depot, highways,
railways, industrial engineering and other types of industrial and
civil buildings of the drainage ditch, cable ditch use, often known
as the rain grate, steel cover plate.
Welded Steel Grating Advantages:
1. The surface of ditch cover plate adopts hot dip galvanizing
surface treatment, which has strong anti-rust ability and is
maintenance-free and replace-free for up to 30 years.
2, due to the use of high strength carbon steel as raw material, so
that the steel grid has a very high strength: strength and
toughness is much higher than cast iron, can be used for wharves,
airports and other large span and heavy load environment.
3, the installation of the domestic more advanced anti-theft
design, made of steel grid drain cover and frame with hinge
connection, anti-theft, safety, easy to open.
4, save investment with materials: large span, heavy load, lower
than the price of cast iron;
It can also save the cost of replacement of cast iron covers due to
theft or crushing.
5, the product appearance is beautiful: simple lines, silver
appearance, composite modern aesthetic requirements.
6, large mesh with the best drainage: water leakage area of 83.3%,
more than twice as much as cast iron.
7, rich categories: can meet the needs of different environment,
load, span and shape, can be provided according to customer size
Welded Steel Grating Process:
The process design of steel grid plate is to arrange the material
according to the geometrical information of the sheet according to
the size of the original plate, and the ultimate goal is to make
the material cutting plan take into account the maximum utilization
rate of the material and higher production efficiency.
The principle of steel grid process collocation mainly has the
1, all the full plate size or more than the full plate size of the
steel grid are in accordance with the length of the priority
collocation, collocation size as little as possible and unified,
length range control in 5-7 meters.
2. A small number of narrow plates can be arranged in order of
width from large to small or from small to large, and then can be
combined together in parallel according to length.
3. When the width overflows, the raw material cross bar is used for
edge welding, instead of welding another plate.
4, double rod welding machine each pressure welding 2 bars, can not
appear odd circumstances.
5, between the board and the board to retain the sawing size, if
not enough need to leave a cross bar.
6, for a set of drawings need to be strictly classified.
If multiple drawings are more than 200 square meters, they need to
be matched together. If less than 200 square meters, it can be
considered to match them with small size drawings.
7, for the special-shaped steel grid, need to consider
decomposition and docking, in order to achieve the most economical
8, for flat steel spacing 60 mm plate can be used 30 mm spacing
comb clip for raw material production.
Welded Steel Grating installation:
The connection mode of steel grid plate is fixed and installed with
buckle connector, which is composed of three parts.
