grates traits

1.Light  weight

product weight is only about one third of cast iron, easy to transport, install, repair, greatly reducing the labor intensity.

2.environmental  protection

composite  resin  as raw  material  ,non-toxic, save energy,noise reduction ,no harmless to user.

3. High strength

 its strength is ten times as rigid PVC, much higher than the absolute strength of aluminum to achieve the level of ordinary steel 

4. Corrosion-resistant

 it stainless, no mold, no rot, no paint, the ability of many gas, corrosive liquid medium

5. Safety and security

covers the installation and use of composite materials, the process will not crash and have a spark, especially for use in explosive environments, in addition, the covers with non-slip surface to prevent sliding down to reduce accidents.

6. The overall economic good

 with more than ordinary carbon steel, composite material covers integrated, low cost, although its one-time investment than ordinary carbon steel, because of its long life, and can be used two decades, and no maintenance, thus The overall economic efficiency is much better than using carbon steel.
