Galvanized steel driveway grating floor serrated steel grating

Steel bar grating is one of our main grating products,also know as press weld steel bar grating.Due to the extremely strong and durable for all the bearing application,whice become the most popular grating in the markets.The stability makes them have a much higher performance in the application.

1>material:carbon steel or stainless steel

2>cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.

3>Steel grating is made by the world first-class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.

4>Surface process of steel grating:Types:hot-dipped galvanized,electro-galvanized ,spraying brushing. 95% people choose hot-galvanized because its anti-acid and alkali corrosion capacity range is from PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.

5>Attractive appearance:Simple outline.silver colour and modern.

6>Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.

7>Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.

8>Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety and convenient opening.

Bearing bar
- A flat bar withstanding the main load is in consistent with the span direction .
bearing bar pitch
- the distance center to center of the two bearing bars.
Cross bar
- the connecting bars , made from twisted bar ,round bar or flat bar, which extend across the bearing bars
Cross bar pitch
- the distance center to center of the two adjacent cross bars.
Length
(span)- the maximum dimension of a grating panel ,measured parallel to the bearing bar ,and in the same direction as the bearing bars .
Width
- the maximum dimension of a grating panel ,perpandicular to the bearing bars .and in the same direction as the cross bars.
