Padlocks are the first thing you need. For perimeter security at warehouse docking stations and gates, these are ideal. It is virtually impossible to break or cut the best of them because they are made of hardened steel. Often, it is the gates and fences surrounding them that are the most vulnerable. When you secure your home with a heavy-duty padlock, you stand a good chance of preventing an intruder from entering.

You’ll need a deadbolt lock if your outer defenses fail. Again, strength is the key, and a thick, heavy deadbolt will resist even the most destructive attacks. Despite the fact that installing deadbolts on every door in your building may not be practical, the main access doors and those leading to particularly valuable items or sensitive materials should be protected.

Locks should be installed on all secondary doors inside the building. These doors tend to have mechanisms that can be breached with feeler gauges or credit cards. For peace of mind, it’s a good idea to ensure all interior doors are equipped with the most robust locks you can find, and if possible, all of them should have deadbolts.
