Welded Steel Grating Introduction
Hot dip galvanized steel grid plate, also known as hot dip
galvanized steel grid plate, is made of low carbon steel flat steel
and twisted square steel horizontal and longitudinal welding grid
building materials.
Hot dip galvanized steel grid plate has strong impact resistance,
strong corrosion resistance heavy load capacity, elegant and
beautiful, in the municipal roadbed and steel platform construction
projects have superior performance.
High cost performance, hot dip galvanized steel grid is widely used
in the old and new roadbed paving ditch road construction projects.
The surface of hot-dip galvanizing steel grating is treated with
special hot-dip galvanizing, and its chemical and physical
properties are stable, and it is not easy to be corroded and
oxidized by air and microorganisms.
It can obviously enhance the trench load force.
Prevent collapse.
The hot dip galvanized steel grates with flat steel spacing of 3 cm
are of great impact resistance and have the characteristics of
maximum span.
The longer its service life is, it is generally within the range of
40-50 years.
Hot-dip galvanized steel grating is a very good steel frame
structure and weighing platform if no destructive factors are
considered to be involved.

Welded Steel Grating Application:
Suitable for alloys, building materials, power plants, boilers.
Shipbuilding.
Petrochemical, chemical and general industrial plants, municipal
construction and other industries, with ventilation, light,
anti-skid, strong bearing capacity, beautiful and durable, easy to
clean, easy installation and other advantages.
Steel gratings have been widely used in all walks of life both at
home and abroad, mainly used for industrial platform, staircase
pedal, banister, channel floor, railway bridge service, high tower
platform, the drain cover, manhole covers, road barrier,
three-dimensional parking lot, organs, schools, factories,
enterprises and institutions, the stadium fence, garden villa, also
can be used as a residence outside the window, balcony guardrail,
highway, rail barrier, etc.
Welded Steel Grating Advantages:
1. Can be added in the peripheral welding kick plate (side plate),
decorative plate guard plate, install fittings and other
accessories.
2. Flat steel with different specifications from the loading flat
steel is used to wrap the edges, or Angle steel, channel steel,
square pipe, etc.
3. Handles and hinges can be installed on the platform steel grid
plate that needs to be moved or opened frequently.
4. The cladding welding standard of the platform steel grid plate
is: one for every five series 1;
Series 2, one for every four welds;
Series 3 welds one per three.
The weld shall be a single fillet welding of not less than 3mm, and
the weld length shall be 20mm.
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
following aspects:
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
material.
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.
