Mild carbon steel provides an economical, high strength for uses in most industrial and commercial applications.
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.
Galvanized Steel Grating offers the following advantages compared with steel grid sheets:
Galvanized Steel Grating 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.

Keys for installing the Gratings
The cross bars should be on the top while installing the gratings. The gratings should be always firmly attached onto their supports with following methods:
1. Welding Fixed
Suitable for those permanently installed gratings or those which are not to be removed frequently
2.Use of Clips and Screws
Suitable for gratings that are to be removed frequently.and won't damage the Grating itself.
3.Space for cutouts
When the cut of a corner is necessary while meeting a round obstacle, the diameter of the corner should be at least 50mm wider than that of the round obstacle. All rectangular cutouts are made with a space no wider than that of the flat iron of the graings.
