Galvanized steel grid board is the production of steel grid board,
the anti-rust processing.
There are two kinds of hot-dip galvanized steel grating and
electric galvanized steel grating.
Galvanized steel grid has the advantages of ventilation and light
transmission, anti-skid, strong bearing capacity, beautiful and
durable, easy to clean and easy to install.
Hot dip galvanizing standard: GB/T 13912-2002 "steel parts hot dip
galvanizing technical requirements and experimental methods" steel
grid plate as a new material, new products are being increasingly
widely used, its more superior performance and good performance
ratio shows its application prospects.

(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
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) hot dip galvanized steel grating 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.
This is the difference between true and false hot dip galvanized
steel grid four characteristics.
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.
Hot Dip Galvanized Steel Grating Advantages:
1. hot dip galvanized steel grid corrosion resistance is very good,
the general hot dip galvanized steel grid zinc amount of about
70um, galvanized layer of adhesion and hardness is good, it is at
high temperature to melt zinc ingot, in some auxiliary materials,
and then the steel grid immersed in galvanized groove, the surface
of the steel grid attached to a layer of zinc layer.
It's an electrochemical reaction.
2. The appearance of bright and beautiful color, after hot dip
galvanized steel grid silvery white appearance, very atmospheric
from afar.
3. hot dip galvanized steel grid long service life: according to
the place of use, the coastal area is generally about 20 years, if
the surface is not large wear, time can be a little longer;
Inland areas, that drought less rain, air humidity is small, less
corrosive media, hot dip galvanized steel grid life to reach more
than 30 years without a problem.
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.
Can choose welding and installation clamping two ways.
The advantage of welding is that it is permanently fixed and will
not be loosened. The specific position is on the first flat steel
at each corner of the steel grid plate. The weld length is not less
than 20mm and the height is not less than 3mm.
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 not to clamp, directly screw head welding on
the beam, ensure that steel grid board will not stair step board
because of the installation clip loose and slide from the beam.
