China manufacturing road drainage stainless steel grating

 

 

     Steel grating is flat steel bar according to a certain distance and cross arranged and 

 

welded into the middle of a square lattice with an iron and steel products ,steel grating 

 

generally use carbon steel production,appearance of hot dip galvanized,can serve to prevent

 

 the role of oxidation,can also be made of stainless steel .

 

 

1. Surface Treatment:

• Hot dip galvanized : If the thickness of bearing bar is more than or equal to 5mm, the average thickess of coating should be not less than 5mm, the average thickness of coating should obey GB/T13912-2002 standard.

 

• Painted: Adopt spray [ainting, brush of dipped method acording to customer' s requirements.
• Untreated

3. The advantages, specific application and features of steel grating:
Steel grating offers the following advantages compared with steel grid sheets:

• Steel structural platform  has light weight, good strength, large carrying capacity and can save materials and cost. It offers good ventilation of light and wind, a modern sense, aesthetic appearance and anti-skid safety. It is also easy to clean, easy to installation and durable for uses.

 

• Steel grating products are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial

 

 

4.  Product 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.
