     flooring and platform steel grating panel/walkway steel grating/walking 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 .

 

 

Product Detail

 

 

 

 

Surface process of gratings: there are three types:hot-dipped galvanized ,electro-galvanizedand 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.

 

 

 

 

Product Features

 

    High strength, light structure, a strong bonding structure of the grid so that it has a high load, the structure of light, easy lifting; shape beautiful, durable, hot-dip zinc surface treatment so that it has a very good corrosion resistance, surface gloss appearance ; ventilation, lighting, cooling, explosion-proof, anti-skid performance is good; no plot dirt, rain and snow is not the plot, not water, self-cleaning, easy to maintain.

 

Product Advantage

  

   Light weight, great load-bearing capacity, non-slip and safe, easy installation, material-economic, sturdy and durable, ventilated, easy to clean and attractive appearance.
