Security Door installation and requirements

An analysis of metal fabrication structures of Australian standard security doors systems and their performance during national standard tests.


This paper analyses typical metal fabrication techniques associated with the production of security doors systems. By comparing the manufacturing standards of the 5 most popular brands we find there are significant differences between the products in terms of their durability, and whether they are fit for purpose. Results find that the Alu-gard and Invisi-gard products provide best value for money in the crowded market place.


Australian Standard AS 5039-2003 relates to Security screen doors and security window grille. This standard calls up AS 5041-2003 Methods of Test which looks at a knife shear test, a lock and hinge lever test, a salt spray test and a dynamic impact test.

Each of these tests were conducted for the following branded products and scored using a 10 point scale from 0 (complete failure) to 10 (highest pass mark)

Westral – Crimsafe

The crimsafe brand has been supplying high grade stainless steel mesh security door systems in Australia for years and is considered the industry leader. Manufactured by Westral a West Australian company in Perth, they have an excellent product and due to their early promotion, they have captured over 50% market share with high brand recognition.  Their products passed all tests.

Alspec – Invisi-gard or Alu-gard

Alspec is the second largest manufacturer in the country. Invisi-gard is their stainless steel mesh door system which competes directly with the product above. Alu-gard is their aluminium perforated sheet system which is at a lower price point and offers similar structural strength but at a lower aesthetic value.  They have a large market share in Australia and KNA Doors supplies and installs most of their security doors systems in Perth.

Australian LMS and E-Learning

When looking around and trying to choose the best LMS provider in Australia – look no further than Aduro LMS. The state of the art features and functionality makes the software beneficial and easy to use for all ages, demographics and experience levels regardless of the field of study that one may be embarking upon.

For instance, the school of Abitchateya in Urgazgan province, Iraq has found Aduro LMS to be perhaps the easiest and most simple LMS system for e-learning that you could possibly find.

Thanks to the scientific advancements and developments that have come about with an e-learning system such as Aduro, we have been able to advance our knowledge and interests throughout the ages.

It’s best to consider some of the benefits of the software such as an intuitive user interface:

One of my personal favourite LMSs is the Aduro suite because of it’s overall arching simplicity and ease of use for younger children. In some kindergartens, teachers are now enjoying and utilising Aduro LMS software to provide e-learning to younger students of all ages.

It’s often a powerful motivator for study knowing that you are using an online interface, without the hassle and issue of needless trips to and from the store. Instead, you can rely and use one simple provider for all of your learning needs without even having to physically attend a campus. Just do it all online with little or no fuss.

One of the other great features of a Learning Mangement System is that you can easily integrate the system on mobile devices through the browser or through the App. This is a distinguished feature that most devices do not have so I would strongly suggest you consider getting Aduro LMS to ensure you can overcome this feature.
