Corrosion
Why are some products more likely to corrode?
GRADE 316 SHOULD BE SELECTED AS A MINIMUM WITHIN FIVE KILOMETRES OF THE SURF.
Stainless steel is a generic term for a family of corrosion resistant alloy steels containing 10.5% or more chromium.
All stainless steels have a higher resistance to corrosion than their mild steel counterparts. This resistance to attack is due to the naturally occurring chromium-rich oxide film formed on the surface of the steel. Although extremely thin, this invisible, inert film is tightly adherent to the metal and extremely protective in a wide range of corrosive media. The film is rapidly self-repairing in the presence of oxygen. Damage by abrasion, cutting or machining is quickly repaired.
The less expensive grades (such as 304) will probably become tea stained or even suffer more severe corrosion. Grade 316 has excellent corrosion resistance in a wide range of media. Its main advantage over grade 304 is its increased ability to resist pitting and crevice corrosion. It resists ordinary rusting in virtually all architectural applications, and is often chosen for more aggressive environments such as sea-front buildings and fittings on wharves and piers.
Grade 316 has virtually the same mechanical, physical and fabrication characteristics as 304 with better corrosion resistance, particularly to pitting corrosion. Invisi-Gard Stainless Steel Security Products use only 316 Marine Grade Stainless Steel.
You can rest assured your new security doors and screens will look great for years with only a moderate amount of maintenance. And unlike some other competing products your warranty is not subject to the ongoing use of a proprietary cleaning product.
WHEN TWO DISSIMILAR METALS ARE CONNECTED OR IN CONTACT AND ARE IN THE PRESENCE OF A CONDUCTING ELECTROLYTE SUCH AS WATER OR EVEN DUST, THE MORE ACTIVE METAL WILL CORRODE AND PROTECT THE LESS ACTIVE METAL.
Aluminium is more active than stainless steel and will preferentially corrode in the vicinity of the contact zone between the metals.
In the case of security screens, the aluminium is more active than the stainless steel mesh or any stainless steel fasteners, and so will corrode first, while the stainless steel will be protected by this galvanic phenomenon.
The rate of galvanic corrosion is governed by the size of the potential difference between the metals in contact, and by the conductivity of the electrolyte.
As a rule of thumb, if the potential difference is less than 0.1 volt, then it is unlikely that galvanic corrosion will be significant.
In the case of Stainless Steel and Aluminium the current difference ranges from between 0.175 and 0.55 Volts depending on the specific alloys concerned.
It can be seen that there is a high likelihood that corrosion will occur in any installation where the two metals are allowed to come into contact, either directly, or by way of mechanical fixing.
All Invisi-Gard Stainless Steel Security Products incorporate the Patented EGP Retention Method which locks the 316 Marine Grade Stainless Steel Mesh into the Heavy Duty Extruded Aluminium perimeter framing.
The Pressure Retention Method completely isolates the Stainless Steel from the Aluminium and because it does not rely on screws, or any other form of mechanical fixing, corrosion through dissimilar metals contact is avoided.
Care and Maintenance
Your Invisi-Gard® Stainless Steel Security Screen should only ever need to be washed down with a soft brush using warm water and a mild detergent. Rinse well with fresh water to remove any detergent residue. Do not use strong detergents or abrasive cleaners as they may scratch or damage the surface finish.
The frequency of this maintenance is determined by the location of the product. Refer to the suggested maintenance table.
Only mains water is to be used as recycled, bore or tank water is unacceptable and may lead to detrimental corrosion effects.
Care should be taken to avoid excessive amounts of water entering the main lock and auxiliary 3 point locks. Periodic lubrication of the main lock and auxiliary lock components should only ever be done using graphite powder. Liquid or aerosol lubricants can cause corrosion and damage the locking mechanism.
External contaminants that come into contact with the Invisi-Gard screens such as bird and bat droppings are very acidic and can quickly burn and damage the powdercoat finish of the frame and the mesh coating.
To ensure the Invisi-Gard warranty is maintained, it is essential that these external contaminants are cleaned immediately with a mild detergent, soft bristled brush and rinsed thoroughly with mains water.

Great experience from beginning to end. Communicated well, timeframes all kept, price good. The installer was very friendly. Highly recommend.
Cath Dunlop
Very happy with the two triple locking security door screens that they supplied and installed and the installer did a great job and very courteous
Bernd Sasse
So happy with the service and quality. My panel glide suits my french doors and windows perfectly. The shutters in my bedrooms look amazing. Thank you to the team at Lakeview. Installed on time, everytime.
Megan Boardman
We asked for a quote, the sales rep came to our home and quoted on the spot. We already had several blinds from Lakeview, and wanted the same quality. The installation date was met and the actual installation was hassle free.
Anne Smart
Great service. Great quality product. No fuss and nice people to deal with. Highly recommend.
Jack Besider
My shutters we installed yesterday = perfection. Love, love, love them!
100% recommend Lakeview Blinds.
Hillary Maccaruthur
Lakeview Blinds at Warners Bay put blinds in our new home. I am very happy with the service and the time we were told it would take. Thank you very much, it was just the last touch to making our home look great.
Christy Standen
This business provided me with contacts for an alternate product even though at this point, it did not involve a sale for them. I would definitely consider using them in the future for blind and shutter products.
Lyn Pritchard
I recommend Lakeview Blinds to all my friends and family. Each time I have a visitor they always complement the beautiful shutters in my house! You couldn't beat the service unless it was with the quality of the shutters! My daughter has just recently ordered some for her own house because she loved mine so much.
