Security Screen Door Grades

Amplimesh® Uses Superior Grades of Stainless Steel and Aluminium

When you look for the right security screen doors and windows to suit your needs, there are a number of things to consider. Amplimesh® prides itself on our high tensile SupaScreen® marine-grade 316 stainless steel and specially tempered IntrudaGuard® marine-grade 5052 aluminium security screen doors and windows. The repercussions of our high-quality metals are far-reaching, this is the attention to quality that ensures your security screens are long-lasting and they stand up to the elements.

And this is why not all security screens are created equal.

Amplimesh® Stainless Steel and Aluminium Grades

Amplimesh® SupaScreen® and IntrudaGuard® don’t compromise on the grade of metal used, so that you can sleep peacefully knowing you are safe from intruders. Our SupaScreen® security screens are made of high-tensile 316 stainless steel and our IntrudaGuard® security screens are made of tempered 5052 aluminium, both are marine-grade for additional durability.

High Tensile Marine-Grade 316 Stainless Steel SupaScreen®

Amplimesh® SupaScreen® security screens use 0.8mm high tensile wire of the highest quality and consistency. To cut costs, many of our competitors use 304 stainless steel mesh which doesn’t appear to hold up to would-be intruders and the harsh Australian environment as well. This can be attributed to the lack of molybdenum in the composition of 304-grade stainless steel which is critical in the prevention of corrosion. Please ensure that all products you select meet the Australian Standards and if in doubt contact the National Security Screen Assoiscation.

What is High Tensile Stainless Steel?

Also known as ultimate strength, high tensile refers to the strength of the metal; high tensile stainless steel is stronger than other grades of steel. The high tensile attribute of the stainless steel used in SupaScreen® security screens further ensures the metal is able to withstand higher tension and stress than lower grades of steel. This is why grade 304 stainless steel which many of our competitors use isn’t as strong. Our stainless steel is rated at a tensile strength of 970MPa.

What Steel Do Our Competitors Use?

Many of our competitors use the more common 304-grade stainless steel which is a good grade of steel, but it is not suitable for marine and washdown applications. The added molybdenum in 316 stainless steel offers greater resistance to chemical attack, corrosion and coastal environments than 304 stainless steel.

Simply put, our high tensile marine-grade 316 stainless steel SupaScreen® range will last longer.

Tempered Marine-Grade 5052 Aluminium IntrudaGuard®

Amplimesh® IntrudaGuard® security screens use 1.2mm tempered 5052 aluminium. This grade of aluminium is especially resistant to corrosion which is why it is the preferred aluminium for marine environments and applications. This aluminium also has a higher fatigue strength than most aluminium, giving it excellent workability and making it easier to form into the intricate shapes and detail required to create the perfect aluminium security screen.

What is Tempered 5052 Aluminium?

Tempering is a process used to strengthen the metal, in much the same way as high-tensile stainless steel is stronger and responds better to stress, so does tempered 5052 aluminium. In the case of 5052 aluminium, the tempering process is performed over a low temperature by rolling out the metal. The result is aluminium which has a fatigue strength higher than most aluminium alloys, especially in comparison to the aluminium our competitors use which are the most common structural or architectural grade.

What is Marine-Grade Metal?

Marine-grade metals are built to withstand wet and harsh coastal environments, they are tested to ensure that they maintain their integrity and continue to perform without fail. What makes marine-grade stainless steel resistant to corrosion is the addition of molybdenum. Marine-grade aluminium has higher levels of chromium and manganese to protect it from corrosion.

Why Do You Need Marine-grade Metal Security Screens?

The corrosive quality of seawater can be attributed to its high concentration of chloride. Carried by an ocean breeze, sea spray pits and corrodes exposed metal, causing its deterioration and weakening its structural integrity. This is exactly why marine-grade stainless steel and aluminium are essential. Without marine-grade metals you will have gone to all that effort, at great cost, to have security screen doors and windows fitted, only to have them corroded in a jiffy. While many of our competitors have tested their security screens against up to 3 000 hours of direct sea spray and passed, we have gone much further and tested our products against 10 000 hours of direct sea spray and passed with flying colours!

Urban environments can impact and denigrate materials, That’s why it is important to ensure the raw materials used are of the highest quality. And put simply the decision is also one of stregth.

How does all of this impact your choice in security screen doors and windows?

Do Our Competitors Products Comply With National Standards?

Some competitors have mentioned that their security screens comply with Australian national standards, but have they revealed their test results? Compliance is essential but how well did they test? Amplimesh® has passed all of the safety tests and even exceeded the requirements. This can be attributed largely to the high grades of stainless steel and aluminium we use to manufacture our screens.

What Are Our Competitors Warranties?

Because some of our competitors use lower grades of stainless steel and aluminium, their security screens simply do not last as long. Some competitors cannot offer a warranty beyond 7 years. Considering the cost of installing security screens and windows, this may well defeat the object. Other competitors are able to offer up to 15 years on their stainless-steel screens. With regular cleaning every three to four months (or more regularly in direct sea spray), your SupaScreen® warranty will last 16 years, the longest warranty currently in Australia, and your IntrudaGuard® warranty will last 10 years. That is the level of quality we should come to expect from a product which had been designed and manufactured to protect our loved ones.

How Are Our Competitors Security Screens Fastened to Their Frames?

Easily overlooked, another very important consideration when choosing a security screen is how the screens are fastened to their frames and are they exposed. Using our Hidden Fix option on Security window screens all your fixings will be concealed.

With an in-depth understanding of the grades of stainless steel and aluminium Amplimesh® use on their security screen doors and windows, choosing the right solution is easy. Get in touch if you have any other questions.
