Door Grille for protection

Dear Sri Murni Management,

Due to extra security protection in this Condo, some residence had install door and window grilles. I myself did it at the back area/ kitchen- washing area sometime 2 years ago. We were told that there is a standard design to be used- the square ones and white for unity looks. However, we do see some other designs and colours around this condo. Can we have your comments on this please. Are you guys going to standardise it for the looks. Hope to hear from you.
