The government standard for forced entry was designed for attacks that escalate – not planned attacks.

The SteelWeave™ Metal Mesh Grille complements and enhances any building’s design while still providing security. Made of a woven type 316 stainless steel mesh material, it exudes elegance while the multiple patterns transform a standard security grille into a piece of rolling art.
