You want the opening secured without staring at bars, and you want it to still look right after a few wet seasons
The objection the product page names first is that a screen spoils the outlook: no longer do you need to look at ugly grills, bars or similar obstructions that spoil your view. The second problem is the air. The stainless steel industry body advises grade 316 as a minimum within five kilometres of the surf and warns that hot, humid tropical conditions make surface corrosion worse, and Cairns averages 72 percent humidity at 9am against a mean maximum of 29.1 C. Tea staining is a cosmetic discolouration rather than a structural failure, so a lesser grade will usually keep working while looking neglected, which is the part nobody raises at the point of sale. It also decides how much washing the screen needs to keep its warranty intact. SCREENGUARD is a 316 marine grade stainless steel mesh system in T6 grade high tensile extruded aluminium frames, manufactured and finished in a variety of colours in Queensland, and tested for dynamic impact, knife shear, anti-jemmy, pull and probe. It carries a full 10 year manufacturer's warranty conditional on regular maintenance with SCREENGUARD Powawash, which is less a catch than the normal care for coastal stainless: the stainless steel industry body suggests washing the stainless whenever the window beside it needs washing.
