1. Hot dip galvanized steel grid plate is made of loaded flat steel
and horizontal bar arranged according to a certain distance between
longitude and weft. The original plate is welded on the high
voltage resistance welding machine, and the finished product is
made by cutting, cutting, opening, edge wrapping and other
processes.
2, hot dip galvanized steel grid type: according to the
manufacturing process is divided into pressure welding, pressure
lock hot dip galvanized steel grid;
According to the surface shape of hot dip galvanized steel grating,
it can be divided into tooth type, plane type, I type and compound
hot dip galvanized steel grating.
3. A brief introduction to the identification method of hot dip
galvanized steel grating:
(1) the center spacing of flat steel: according to the series:
Series 1 is 30mm;
Series 2 is 40mm;
Series 3 is 60mm.
(2) Rod center spacing: Series 1 is 100mm, Series 2 is 50mm.
Other specifications can be customized.
(3) flat steel: the material is Q235A or stainless steel, with
ordinary plane type, anti-skid tooth type and section I type.
Common specifications are 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3,
50*5, 65*5, 75*6, 100*8, 100*10 and so on.
(4) bar: round steel, twisted square steel, square steel or
hexagonal steel made of Q235A or 304 stainless steel.
Twisted square steel is made by drawing and twisting the square
die, and its common specifications are 5*5, 6*6, 8*8mm, etc.
Hot dip galvanized grille plate (hot dip galvanized grille plate)
is the most widely used grille plate in the most widely used
products, steel grille plate welded after hot dip galvanized
treatment, not only beautiful appearance, but also can play a good
role in corrosion prevention and rust prevention, prolong service
life, by the majority of customers.
Hot dip galvanized grid plate is characterized by: high strength,
light structure;
The solid grid pressure welding structure makes it has the
characteristics of high load bearing, light structure, easy to
hoisting and so on;
Beautiful appearance, durable.
Acid and alkali corrosion ability: in the range of pH 6 to pH 12.5,
the zinc layer surface formed a stable protective film, good
corrosion resistance.

Hot Dip Galvanized Steel Grating Advantages:
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.
Hot Dip Galvanized Steel Grating Process:
Steel plate process with manual welding process and welding machine
process, surface treatment of hot dip galvanizing and painting, the
composition of ordinary steel plate is made of flat steel and twist
steel welded together, is composed of flat steel welded with
special specifications, steel grid plate can be divided into common
flat steel and sawtooth toothed plates, serrated flat non-slip
effect is more outstanding.
The connection mode of steel grid plate is fixed and installed with
buckle connector, which is composed of three parts.
Hot-dip galvanized steel grid plate can be installed in two ways:
welding and clamping.The advantages of welding are permanent fixation, not loosening,
specific position in the first flat steel at each corner of the
steel grid plate, the length of the weld is not less than 20mm, the
height is not less than 3mm of fillet welding.The advantages of the mounting clip are that it does not destroy
the hot dipping zinc layer and it is easy to disassemble. Each
plate needs at least 4 sets of mounting clips. The number of
mounting clips increases with the increase of the length of the
plate.The safest method is to weld the screw head directly to the beam
without clamping down, so that the steel grille plate will not slip
from the beam due to the loosening of the clamping.
