Municipal Drain Q345 Steel Driveway Grates Grating Serrated Type
Hot Dip Galvanized Cover Plate For Municipal Drain Steel Driveway Grates Grating
Steel Driveway Grates Grating Introduction
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.

Type of hot dip galvanized steel grating: according to the different types of flat steel, hot dip galvanized steel grating is mainly divided into the following three types, their respective characteristics are as follows:
1, plane type: plane type hot dip galvanized steel grid plate is the most widely used hot dip galvanized steel grid plate, mainly used for platforms, walkways, all kinds of ditch cover, step board and so on.
2, tooth type: compared with the plane type hot dip galvanized steel grating, tooth type hot dip galvanized steel grating has better anti-skid effect.
3, I-shaped: compared with the plane type hot dip galvanized steel grating, I-shaped hot dip galvanized steel grating has the characteristics of light weight and more economic without greatly reducing the load capacity.
Steel Driveway Grates Grating Application:
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.
Steel Driveway Grates Grating Advantages:
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.
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.
