Material:

Because grating is often used in areas that require high requirements such as corrosion and oxidation resistance, the material also has an impact on the protective performance. Steel grille is prone to rust and corrosion, need to protect and maintain; while aluminum alloy, stainless steel grille has a better corrosion resistance, anti-oxidation, UV protection and other properties, no need to protect the treatment.

Grille in some occasions also need to take into account the aesthetic and decorative effect. Because of the different materials, the grille surface pattern, color, texture and other characteristics are different. Steel grille surface is generally treated as non-slip, lacquer or galvanized and other forms; while aluminum alloy, stainless steel grille surface can be treated as a mirror, spraying and other forms, more decorative.
