Both pass the same AS5041 forced-entry tests, so the security floor is identical and you are not trading safety for budget. Perforated aluminium is the cheaper option, carries a seven year warranty, and is a perfectly good screen almost anywhere. Stainless costs more, holds up better in salt air, gives up less of the view because the weave is finer, and carries a lifetime warranty. Within a few streets of the water, go stainless. Inland, aluminium is usually the sensible spend.

No, and it matters which one you end up with. Flyscreens keep insects out. That is the whole job, and they carry no forced-entry rating. Security screens and doors are tested to AS5041 against jemmy, knife and impact attack. We make both, so we have no reason to steer you toward the wrong one. Tell us what you are actually trying to solve and we will tell you which you need.

Stainless, in most cases. It is 316 marine grade, and the patented retention system keeps the mesh from touching the aluminium frame, so there is no dissimilar metal contact for salt air to work on. The aluminium is corrosion resistant too and it is a perfectly good screen inland, but salt is the one condition where the material difference actually shows up.

Up to a point, and the point differs by material. Perforated aluminium meets bushfire requirements up to BAL-29 on the strength of its 2mm perforation. Stainless mesh is rated from BAL-LOW through to BAL-40. Check your BAL assessment before ordering, because above BAL-29 the aluminium is out.

Both. Tell us which you want in your enquiry and we will quote it that way. Supply and install carries Bellano's ten year workmanship warranty on the fitting itself, which sits alongside the manufacturer's warranty on the product.
