Rust Protection Welded Steel Grating 32x5mm Square Serrated Non
Rust Protection Square Serrated Non-Slip Grille Plate Welded Steel
Welded Steel Grating Introduction:
Steel grid plate, also known as steel grid, steel grid plate, grid
plate, etc., is made of flat steel in accordance with a certain
distance and bar (new twisted square steel, square steel, round
steel, flat steel, etc.) for cross arrangement, and welded into the
middle with a square grid of steel products.Daily often used and
see the steel grid plate is generally made of Q235 low carbon steel
hot rolled flat steel in accordance with a certain distance and the
square steel bar of the twisted cross welding together, and welded
into the middle with a square grid, usually in the outside of the
steel grid for hot dip galvanized treatment, to prevent corrosion.

Welded Steel Grating Application:
Anti-rust metal steel grid plate has been widely used in all walks
of life at home and abroad, the products are widely used in
petroleum, chemical, alloy, building materials, power stations,
boilers, shipbuilding, and general industrial plants, municipal
construction and other industries of the platform, walkway, stairs,
gutters cover, fence, railing, drainage manhole cover,
manufacturing and so on
Welded Steel Grating Advantages:
1. Beautiful appearance: simple lines.
Silver appearance, modern trend.
2. Drainage: The water leakage area reaches 83.3%, more than twice
that of cast iron.
3. Hot dip galvanizing: strong rust resistance, maintenance and
4. Anti-theft design: the cover and the frame are connected by
hinge, which is anti-theft, safe and easy to open.
5. Save on investment: Big jump.
Under heavy load, it is cheaper than cast iron and saves the cost
of crushing and replacement.
6 high strength: strength and toughness is much higher than cast
iron, can be used in wharves, airports and other large span and
heavy load environment.
7. More specifications: to meet different environment, load.
Span, size and shape required.
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.
Hot Dip Galvanized Steel Grating Package delivery:
