Frequently Asked Questions

What is a security door?

The Superior Door Company is a specialist in custom making Steel Security Doors. A Security Door provides you with a safe feeling by giving you a barrier between yourself and an unwanted visitor. It also allows you to keep a timber door open in Summer to let fresh air flow into your home.It is essential for evaporative cooling and can save you from using an air conditioner, therefore being environmentally friendly.

Our 3 and 4 way locking steel doors with high security Mul-T-Lock lock and cylinder provides the greatest protection available which prevents criminals from picking, drilling or bumping the door open.

For a Crimsafe Door the cut proof Stainless Steel Woven Wire is your security instead of the bars in other security doors. This cut proof wire is capable of withstanding knife attack as specified in the Australian Standards and also allows maximum ventilation. The Crimsafe security screen door comes standard with 3 hinges and 3 point locking in the hinged version.

What is a security door made of?

At The Superior Door Company we specialise in using steel for our Security Doors. After we have made the steel door, it will be zinc plated to protect it from corrosion and then powder coated to give it a long lasting, quality finish. Alternatively the Crimsafe security door has an aluminium frame and are the only doors featuring the unique Crimsafe screw clamp system.

Do you have solutions for bush fire and fire prone areas?

If your home or business is ever caught up in a bushfire, Crimsafe security screen doors and windows will help to protect it from damage.

Floating embers, radiant heat or naked flames all pose an ignition risk to your property. But Crimsafe won’t permit floating embers to pass through window spaces, and it’s fire attenuation feature will reduce the intensity of radiant heat flux and naked flame by up to 45% (confirmed through stringent testing by the CSIRO).

Do you use solid bars in your window grilles?

Yes. We offer a range of steel window grilles with solid bars in a range of designs to suit your home. Our sales staff can offer you ideas for your Window Grille designs when they measure your window space.

My home is very modern, how do I achieve window security without using barred window grilles?

Security flyscreens such as Crimsafe use a Stainless Steel cut resistant wire and a unique screw clamp system that offers superior protection for the window without interrupting your view with bars.

What lock should I have on my steel gate?

A high security mortice lock is a quality solution for a pedestrian steel gate or a security gate. This can be locked and unlocked at will. The type of mortice lock installed into your steel gate would be adjusted according to your needs. For instance a security gate combined with an electric strike will use a different lock to a security gate that is only going to be manually locked and unlocked with a key. Speak to our sales staff for the solution for you.
