What Prowler Proof does

Prowler Proof (legal entity Gershwin Pty Ltd) is an Australian privately-held manufacturer of welded security screens, security windows, and hinged and sliding security doors, headquartered in Brisbane and operating from a single state-of-the-art factory in Banyo, Queensland. Founded in 1985 and in continuous operation for roughly 40 years, the company sells six product ranges — ForceField (316 Marine Grade stainless steel mesh, SL200), Protec (perforated aluminium, SL200), Guardian (fall-prevention stainless mesh, NCC compliant), Diamond (AS5039-passing diamond grille, SL100), Insect (fibreglass and micro-mesh fly screens) and Heritage (cast aluminium panels) — plus accessories such as Petway pet doors and Lockwood locks. All products feature toughened robotically welded corners in place of screws or rivets, full perimeter mesh bonding, the proprietary H.I.T. (Hidden Installation Technology), and an in-house 7-stage powder coating process.

The manufacturing process is fully automated and computer-controlled, with robotic welding and twice-daily lab testing of the powder coat finish. The factory is independently audited for compliance with Australian Standard AS5039-2008, and Prowler Proof holds certifications across knife shear, jemmy, dynamic impact, probe, pull, shear, cyclone, fire attenuation and corrosion resistance, with ForceField and Protec achieving Security Level 200 and the 10-year full-replacement warranty marketed as Australia's only one of its kind.

Prowler Proof distributes exclusively through an Australia-wide network of NSSA-certified dealers, with separate pathways for homeowners (retail) and for the builder/trade and commercial segments. Dealers provide in-home measure and quote, professional installation and after-sales support, and the company operates a PPDN dealer portal for operational and marketing support. Pricing is quote-based on custom-made-to-order specifications, with Humm90 Interest Free finance available from A$250. Customer segments are homeowners (primary, residential), builders and trade installers, and commercial/government customers including educational and social-housing projects such as St Johns College at the University of Queensland and Brisbane Common Ground.
