Here’s a pre-hung metal clad door system waiting for final quality control in our factory before packing and shipping to our customer.

This door system uses a heavy duty steel door frame and comes complete with industrial door hardware already fitted.

For this particular door, we’re using Colorbond for the metal cladding but we can also clad doors in galvanised steel or stainless steel for even more strength and corrosion resistance.

We recently took delivery of this rather impressive (and heavy) sheet of high-grade steel for the fabrication of a ballistic rated door.  The 10mm steel plate is BISALLOY® Armour HHA 500 steel and the door will be rated to AS/NZS 2343:1997 level R2 to stop 3 strikes from a 7.62mm rifle round as well as S1 that will stop a 12 gauge shotgun shell.

The Bisalloy steel is quenched and tempered making it suitable for both civilian and military applications where both lightweight and high bullet and projectile penetration resistance is required.

This high-security, reinforced steel door will be made of several layers of sheeting and finishing materials laminated to this armour plate.  The idea is that the plate stops and fractures the projectile while the layered materials catch the resulting spalling and bullet splash.

Here are a couple of diagrams that might help you understand this concept.

Bullet splash is pretty much what it sounds like and is what happens when a relatively soft object, in this case, a bullet, hits a very hard surface such as the armoured steel plate inside this door.  The bullet shatters and fragments bounce off the plate much like a water balloon hitting a wall.  This material still has a lot of energy and can act like shrapnel from an explosion so it is important that the door contain and neutralise it.

Spalling is what can happen on the other side of the armoured plate from the bullet splash.  Spalling actually results from the impact of the projectile fragmenting the target itself with pieces of the target then becoming potentially deadly projectiles.  The lining materials of our ballistic rated doors also work to contain this potential threat.

If you require bulletproof doors or a ballistic rated door for both civilian and military applications, please don’t hesitate to contact us.

Another pallet of fire safety doors on our pallet wrapper getting ready to ship to our customer who is a large builder in Melbourne.  These doors happen to be standard-sized fire-rated doors but fire safety doors could also be smoke or life safety doors which don’t carry the same overall FRL rating.

If you’re interested in the difference between smoke doors and fire doors, you might want to check out the article below from our blog.

Smoke Doors Vs Fire Door Distinctions

While these doors are all the same standard size, most of the doors we make are custom-sized and a pallet of doors would normally have doors of many different sizes.

We’ve recently invested in significant new capacity to speed up our process of making fire safety doors like these.  If you’re project needs doors in a hurry, don’t hesitate to contact us on the number at the top of the page.

We ship all across the country usually using Mainfreight or other major logistics companies so you’ll get your doors in a hurry.
