1. What is the difference between mesh and grille security doors?
Grille doors use an open aluminium grille pattern, a visible barrier with maximum airflow. Mesh doors use a security mesh screen that also helps keep insects out while maintaining the view from inside.
2. Do you supply security doors for commercial buildings?
Yes. The same hinged security door panels are used across homes, rental properties and commercial buildings, and the panel only option suits fit outs where frames are fabricated on site.
3. Can I buy just the door panel?
Yes. Every mesh and grille door is available as a panel only or as a panel with frame, so you only pay for what your installation needs.
