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.

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.

It is not uncommon for apartments and public buildings to have emergency doors for occupants in the case of an emergency situation. Some of the more commonly used are presently known as smoke doors which can also sometimes be called life safety doors and fire doors. Though each of these doors may be similar in nature, they have two distinct purposes. Both of which, however, are designed to create a seal that will keep away the fatal flames and smoke from those who are in these structures at that time.

Typically, while smoke doors have been designed to block out combustible items and smoke, the fire doors are meant to keep the flames away in a separate partition. In either case, due to the safety that these doors provide, they can be used in homes too. So, if you have an interest in how these doors may serve the same purposes for your family, you may want to talk to your local fire professional for their recommendations.

Having said that, here is some basic information that you should know.

First of all, it is important to start with the anatomy of both doors and their basic differences. For instance, the fire door has been designed to be enclosed within the buildings fire-rated walls. Its overall function is to keep the flames from spreading through doorways. Additionally, when people are thinking about the structure and the purpose of the fire door, they will most likely find that fire doors can always double as a smoke door but not vice versa. Simply put, when people are reviewing the distinctions between the fire door and the smoke door, it is important to note that smoke doors do not always have the same capability and features of the fire door. This is because smoke doors have not been designed to prevent the spread of flames from room to room.

Identifying the Different Characteristics Of Each

Fortunately, both doors are very easy to identify when people want to know the difference. This is because these doors must always be marked clearly for everyone to see. In addition to the signs on the doors, people can also learn the difference between each based on the materials that have been used by the manufacturer. For instance, you will be able to see the distinctions by the wood, aluminum and the steel in a smoke door. Everyone should also know in advance that fire doors are composed of materials that resist burning so they can resist the flames for an extended period of time.

Protection Features

When people are in a building with a fire, it is important that people know that the fire doors that they see in the building is designed to keep the flames compartmentalized for at least the time frame of 30 to 120 minutes. One of the main functions of the fire door is to protect people from the fires harmful effects. The type of doors used can also make a difference in protection since these doors are not usually automated but are made to remain shut doing these times.

For people who may not know the primary reason for a smoke door, it is important that you know that these doors are made with specialty seals.  Spartan Doors smoke doors use quality door seals from Kilargo.  These seals are made to protect individuals by only activating when a smoke detector goes off.

Considerations

These doors are only built to last a certain amount of time. So, it is essential that problems in one or both of these doors be addressed immediately. In fact, it really does not matter if the damage is small and not severe since any issues at all must be reported and corrected. Finding the certifications on the doors is supposed to be made easy since there are serial numbers and dates that people will find on the edge of these doors. This information can be used for a varied of situations and circumstances, including asking questions of the manufacturer and the local fireman.

What Are Cyclones?

Large parts of the Australian coastline regularly receive powerful cyclones. This means that many Australians living in at-risk areas need substantial protection. One of the best ways to protect yourself from these frequent natural disasters is to invest in secure, rated cyclone doors.

Cyclones can come by many other names, sometimes called hurricanes, typhoons and tropical storms. They are powerful systems of strong rotating winds spiraling around an area of low pressure. These winds are some of the most powerful in the world, with the highest ever recorded reaching 408 km/h (measured on Barrow Island, Australia, during Cyclone Olivia).

Cyclones can cause enormous damage to communities and the environment, which is why adequate protection is necessary in at-risk areas.

Cyclone regions are categorized into four areas, seen below:

A – Normal
B – Intermediate
C – Tropical Cyclones
D – Severe Tropical Cyclones

The western coast of West Australia is at the most risk for severe tropical cyclones, but large parts of the northern, eastern, and western coasts are exposed to intermediate and tropical storms. All in all, four states: West Australia, Northern Territories, New South Wales, and Queensland are at risk for some form of cyclone.

Our Cyclone Doors

Australian Law governs the minimum requirements of cyclone doors.

Our cyclone rated doors are multi-purpose doors ideal for external or internal use in the homes and industrial facilities of at-risk regions. They are manufactured to withstand Category 2 and 3 cyclonic wind categories, which rank among the severest in Australia, and are found predominantly in regions C and D in Queensland, Western Australia, and the Northern Territories. Our cyclone rated doors are engineered and manufactured to exceed the requirements of AS1170.2 and can also be used in less severe regions A and B.

Cyclone doors play a critical role in keeping your business assets safe, and your homes secure. Businesses often use them for industrial buildings, switch rooms, transportable buildings, warehouses, and offices.
