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.
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.
