There is a reason many commercial garages and storage facilities have roller garage doors. They stand out as one of the most secure options due to their unique design. The compact installation and absence of visible leverage points on the sturdy aluminum curtain make them a formidable obstacle for potential intruders. 

Yes, driveway gates can help secure your home by deterring burglars from accessing your property. Climbing a gate slows down burglars while also attracting attention to your gate. If you live further down your property and want to increase security, you can also install a gate security camera that connects to your gate and monitors the area for suspicious activity.

Security doors are not limited to standard sizes, and you can customize them to fit your needs and entryway dimensions. That's one of the fantastic things about security doors—they can be tailored to match your home. Keep in mind that a custom-sized security door will likely cost more than a standard size. 

Ideally, a gate should be able to swing both in and out. However, if it can only open in one direction, it is generally best for it to swing inward. This is often the safest option, especially for deck gates near steps, as you'll want the gate to swing away from the stairs. An inward swing also prevents the gate from opening into a public space, like a sidewalk, and can be more convenient when carrying heavy items like a wheelbarrow into a garden.

There are exceptions, however. The layout of your property may require a different approach. For example, if your property is on a slope, the gate may not be able to swing inward. You should also ensure the gate can open fully without colliding with any objects or blocking access to other areas. For a backyard garden gate where public access isn't a concern, the direction it swings is largely a matter of personal preference. Finally, always check your local building codes, as they may have specific requirements for which way a gate must swing.
