drainage gutter with stainless steel grating cover

     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

2. Quality Standard

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
