Grille plate adopts high strength carbon steel, so that the steel
grille 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.
The toothed steel grille has good drainage: the water leakage area
is 83.3%, more than twice that of cast iron.
Product appearance is beautiful: simple lines, silver appearance,
modern idea, saving investment with materials: long 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.
Hot dip galvanized steel grid plate is produced after the steel
grid, rust prevention treatment.
There are two kinds of hot dip galvanizing and electric
galvanizing.
Hot dip galvanized steel grid according to the manufacturing
process, divided into welding hot dip galvanized steel grid and
pressure lock hot dip galvanized steel grid;
According to the surface shape of hot dip galvanized flat steel, it
is divided into toothed hot dip galvanized, planar hot dip
galvanized, I hot dip galvanized and composite hot dip galvanized
steel grid.
The letter "G" for the hot dip galvanizing mark may be omitted from
the grating code.
Hot dip galvanizing implementation standard: GB/T 13912-2008.

1. Vertical strip spacing: generally 30, 40, 60 (mm);There are also non-standard spacing: 25, 34, 35, 50, etc.
2. Horizontal bar spacing: conventional 50, 100 (mm);There are also non-standard spacing: 38, 76, etc.
3 width: 20-60 (mm);
Thickness: 3-50 (mm).
Widely used in petrochemical, electric power, tap water, sewage treatment, port wharf, building decoration, shipbuilding, self-propelled parking lot, municipal engineering, sanitation engineering and other fields platform, walkway, trestle, trench cover, manhole cover, ladder, fence, factory construction and so on.
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.
Pressure welding steel grid plate is made of load flat steel and
cross bar according to a certain distance by adopting 200 tons of
hydraulic resistance welding automation equipment welding into the
original plate, after cutting, opening, wrapping and other
processes and products customer requirements.
Load flat steel spacing: the center distance between two adjacent
load flat steel, commonly used 30MM, 40MM and 60MM three.
Rod spacing: the center spacing of two adjacent bars is usually
50MM, 100MM, two kinds
In order to prevent the risk of falling, the installation of the
steel grid plate should be fixed by welding as far as possible.
The steel grid plate shall be installed in accordance with the
steel structure plate. After installation, it shall not be moved
laterally or separated from the supporting frame. The supporting
length at both ends of the steel grid plate bearing the flat steel
direction on the supporting frame shall not be less than 25 mm for
each section.
Platform steel grille plates that require removable and detachable
are secured by the mounting fixture of the steel grille plates.
Prevent any shift of the member;
The requirements of the buyer can be supplied by the manufacturer.
In addition to the installation clip made of stainless steel
material, the installation clip made of carbon steel is treated by
hot dip galvanizing. It is suggested that the bolts used for the
installation clip are treated by hot dip galvanizing.
