What Are Sleek Grilles™?
Sleek Grilles™ are a modern alternative to both aluminum and invisible grilles — combining a slim, contemporary profile with HDB and condo-approved child safety. Unlike bulky aluminum bars, Sleek Grilles stay barely noticeable. Unlike invisible grilles, which rely on cables, Sleek Grilles use solid steel bars that can’t
be cut with household tools — giving you real security without sacrificing your view.
