To put it simply, steel doors are highly secure. Known for their exceptional strength and ability to protect against physical attacks, the materials with which they are manufactured ensure they are an effective deterrent against break-ins and other threatening behavior. In some cases they can also serve as a barrier to fires. Whatever your reasons for purchasing steel security doors, you can rest easy knowing your premises will be safe from numerous dangers.
High Security Solid Steel Construction
Steel doors are one of the strongest door options you can have as a result of their microstructure and overall composition. Steel security doors are made from cold-rolled or galvanized steel which is usually 18 to 14 gauge thick. Because of this it can easily hold out against physical damage caused by impact, bending, and cutting making it less likely it have its security compromised. When galvanized or coated, steel doors are often corrosion resistant making them better able to stand the test of time.
Reinforced Core and Frame
While first appearing to be composed entirely of solid steel, steel security doors are usually hollow with a reinforced core. This makes them lighter than solid steel security doors and therefore easier to carry and install across multiple premises. Despite this reduced weight, the doors remain incredibly strong due to the core material, which can be:
- Honeycomb – known for being particularly lightweight with good rigidity.
- Steel Stiffened – reinforced vertically with steel for maximum strength.
- Polyurethane/Mineral Core – known for being fire-rated, this core also adds insulation.
- Solid Core (composite) – superior for its acoustics and impact resistance.
In addition to the core, its robust steel frame makes these high security doors so strong. These frames are commonly built to be anchored into the masonry or concrete, which eliminates weak points resulting in door damage and enhances resistance power to threats like break-ins, fires, and extreme weather.
Multi Point Locking Systems in Our Security Doors
Our steel doors often feature multi-point locking systems which are a huge advantage when it comes to intruder protection in your home or workplace. Unlike standard single-point locking systems (for example, a deadbolt or latch in the middle of the door) which can create a weak point in the door that potential intruders can exploit, multi-point locking systems distribute security throughout the door, preventing it from being forced open at the corners or warped under pressure.
The multi point locking system also offers seal and weather resistance. It pulls the door evenly against the frame, reducing air and water leaks, resulting in better thermal insulation for homes and work premises, higher levels of soundproofing and reduced energy loss.
Fire Resistance for Peace of Mind
Similar to fire doors, steel doors offer certain levels of fire resistance depending on the door itself and the core. Non-combustible materials such as the steel skin is non-flammable and resistant to ignition, while door cores such as the core, honeycomb, or steel stiffeners offer balance and control to the transfer of door heat. Our steel security doors contain higher rates of fire resistance than ordinary doors. Additionally, our USA fire exit doors are CE certified and are installed with 2-point panic hardware.
