Hot dip galvanized steel grid is an open plate steel member which
is composed of flat steel and cross bar in a certain distance and
fixed by welding or pressing lock.
According to the different production methods, it is mainly divided
into pressure welded steel grid plate and pressure locked steel
grid plate.
When the steel grid plate is welded, the steel grid plate fixed by
pressure resistance welding is called pressure welded steel grid
plate at each intersection of the bearing flat steel and the
horizontal bar.
Twisted square steel (twist steel) is usually used for cross bars
of pressure welded steel grates.
Reference from: steel grid plate standard YB/T4001.1-2007.
Hot dip galvanized steel grid plate means that the surface of the
steel grid plate is treated with hot dip galvanized anticorrosion
after welding.
The general surface treatment methods are: hot dip galvanized, cold
galvanized, spraying antirust paint, which hot dip galvanized
anticorrosion effect is better, the price is also high.

8 | Application | - Rotation ways, channels, and platforms for pump rooms and engine
rooms in various ships; - Flooring in various bridges such as railway bridge sidewalks, over-bridges across the street; - Platforms for oil extraction sites, car washing sites and air towers; - Fencings for car-parks, buildings and roads; drainage trench covers and drainage pit covers for high strength . |
Grille plate is suitable for alloy, building materials, power
station, boiler.
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.
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,
Parapets, etc of highways and railways.
High strength, light structure: the solid grid pressure welding structure makes it has the characteristics of high load, light structure, easy to hoisting and so on;Beautiful appearance, durable: hot dip zinc surface treatment makes it has a good anti-corrosion ability, the surface luster is beautiful;Good ventilation, lighting, heat dissipation, explosion-proof and skid proof performance;Prevent accumulation of dirt.
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.
