hot-dipped galvanized 1m width standard size mild steel grating factory made in China

 

Steel Grating Platform is made by carbon or mild steel of certain sizes through the processing of grooving, loc pressure, welding, finishing and other treatment. Industrial bar gratings can be actually made from copper, 

aluminum and oth er materials, 

while galvanized steel grating is the mostly used one due to its economic cost and good property.

Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. 

It can be used for ceiling, interior decoration

 

 

Materials:
Mild carbon steel provides an economical, high strength for uses in most industrial and commercial applications.

 

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 engineering, and they offer the following the features:

Aesthetic outlook: Simple lines and silver appearance meeting the modern trend.

The best drainage: Leakage area of 83.3 percent, more than twice of cast iron products. 
Hot-dip galvanized treatment: Good rust-proof property, maintenance-free replacement. 
Anti-theft design: The cover and the frame is joint with hinge offering security, safety and open convenience..

High strength: The strength and the toughness are much higher than cast iron. Can be used for terminals, airport and other large-span and heavy loading condition. 
Specifications: More specifications and sizes optional for meeting various environment, load, span, sizes and shapes

 

 

Surface Treatment:
Steel grating untreated: Allowing quicker delivery to customers whom fabricate and galvanize the grating on their own.

 

Galvanized: Hot Dip Galvanizing can give a hygienic and clean maintenance free bright finish.
