Steel Driveway Grates Grating Introduction
Steel Driveway Grates Grating(hot dip galvanized steel grid plate)
is the most commonly used steel grid plate the most widely used
products, steel grid plate welded after hot dip galvanized
treatment, not only beautiful appearance, but also can play a good
role in corrosion and rust prevention, prolong the service life,
favored by the majority of customers.
Hot dip galvanized steel 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.

The standard steel grid plate also includes various specifications
of flat steel (applicable to the above four series), flat steel
spacing for 60mm, twist twist bar spacing for 200mm and other
combinations.
Steel Driveway Grates Grating Application:
treatment plant, municipal engineering, sanitation engineering and
other fields of the platform, walkway, trestle, ditch cover,
manhole cover, ladder, fence, guardrail, etc..
Steel Driveway Grates Grating Advantages:
1, 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
2, beautiful appearance, durable: hot dip zinc surface treatment makes it has a very good anti-corrosion ability, the surface luster is beautiful.
3, ventilation, lighting, heat dissipation, explosion-proof, anti-skid performance is good.
4, no dirt, no rain and snow, no water, self-cleaning, easy to maintain
Production Process:
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
Installation Method:
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. Heavy Duty Driveway Drainage Grates
