Product Description

Steel bar grating

 

 

Description:

 

 

1>material:

carbon steel or stainless steel

 

 

2>cross bar pitches

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 gratings

there are three types:hot-dipped galvanized ,

electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property. 

 

 

5>Finish treatment:

 Hot dipped galvanized, cold dipped galvanized, spray painting, 

dip anti-rust oil, can prevent oxidation.  

 

 

6>Surface type

Flat type, serrated type, I shape type(According to requirement made different protective treatment).

 

 

 

Specification of grating steel  

 

 

 

1)The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated  type and I-Shape type 

 

 

2)Bearing bar pitches can be 12.5, 15, 20, 30, 30.16, 32.5, 34.3, 40, 60mm, of which 30mm & 40mmare recommended.

Production Process

 

Features: 

1)Attractive appearance:Simple outline.silver colour,and modern.

2)Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger  

than that of cast iron.

3)Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.

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

5)Saving investment:With large span,the cost is lower than that of cast iron when under heavy load.

And the replacement expenses in case of theft and crushing will be saved.

6)High strength:With strength:With strength and toughness far higher than those of cast iron,it can be used in the environment with large span  and heavy load,such as the wharf and the airport.

7)Many specifications available: The requirement of different environments,loads,spans,sizes and shapes can be satisfied.
