Security DOORS
What Is a Security Door?
A security door can only be called that if it meets AS 5039, the same Australian Standard that governs security screens. To be classified as compliant, a security door has to pass six tests, dynamic impact, jemmy, pull, probe, knife shear and corrosion, and be installed to the AS 5039.2 installation standard. The dynamic impact test alone requires the door to withstand five direct hits of either 100 or 200 joules of force and stay within its frame.
A security door is a different product to a barrier door or a standard flyscreen door. Where a flyscreen door uses a lightweight frame with crimped or riveted corners, a genuine security door is built with toughened welded corners, a security-rated infill, and a robust locking system, typically a 3-point lock as standard, not an optional extra. It has to carry a compliance label to prove it’s been tested and correctly installed.
At Miza Home Security, every security door we supply and install is genuinely AS 5039 compliant, manufactured by Prowler Proof and fitted by me, David, to the AS 5039.2 installation standard. For more on why that compliance gap matters when you’re comparing quotes, see our page on Quality & Compliant Products.
Hinge Doors vs Sliding Doors
Security doors come in two configurations. Both styles share the same welded-corner construction, the same AS 5039 testing, and the same infill options, so the choice comes down to the opening you’re covering rather than a difference in security.
HINGE DOORS
Hinge doors swing open on hinges fixed to either side of the door jamb, and suit single doorways and french door pairs, most commonly your front entry.
SLIDING DOORS
Sliding doors track side to side across the opening and suit wider openings and stacking configurations, most commonly back patios and alfresco areas.
Our Security Door Ranges
ForceField — near-invisible, virtually unbreakable
Woven from 316 marine-grade stainless steel mesh, ForceField is the option when you want the door to disappear visually without giving up strength. It’s rated to Security Level 200 (SL200), the highest classification in the range. Available as both hinge and sliding security doors.
Protec — strong, perforated aluminium for coastal homes
Rather than a woven mesh, Protec uses a single sheet of perforated aluminium, giving extra rigidity and better resistance to salt air. It’s also SL200 rated and built with the same welded, seamless corners as ForceField, a strong choice for coastal properties or where you want a more solid, private look.
Diamond — compliant security at a more accessible price
Diamond looks similar to non-compliant grille doors at a glance, but it’s fully tested and rated to AS 5039 (SL100). Choose Welded Diamond, where the frame and grille are powder coated in matching colours, or SnapLock, with a black grille and your choice of frame colour. Genuine, tested protection without the ForceField or Protec price tag.
Door Options That Aren't Security Rated
Not every door needs to be a security door, and we’ll always tell you plainly when a product isn’t AS 5039 compliant.
Heritage doors use cast aluminium panels welded to a heavy-duty aluminium frame, and suit traditional, federation or Queenslander homes where street-facing character is the priority. They’re not a compliant security door, so if forced-entry protection matters for that opening, we’ll talk you through a compliant alternative.
Insect screen doors are built on the same welded corners as the rest of the Prowler Proof range, so they won’t sag or gap the way a hardware-store flyscreen door does, but they’re not tested or rated as security doors.
Locks and Hardware
A compliant security door isn’t just about the frame and infill. AS 5039 compliant doors are fitted with a 3-point locking system as standard, engaging at the top, middle and bottom of the door, which is designed to resist the door being wrenched open at any single point. This isn’t an upgrade you need to ask for, it’s part of what makes the door compliant in the first place.

Frequently Asked Questions
Hinge doors swing open on side-mounted hinges and suit single or french doorways, typically a front entry. Sliding doors track across the opening and suit wider or stacking openings, typically a back patio. Both are available in the same compliant ranges.
Yes. A compliant security door includes a 3-point locking system as standard, not an add-on, along with a 5-pin cylinder key lock as a minimum.
Yes, though it’s worth knowing our Heritage range prioritises styling over a security rating. If you want the traditional look with full AS 5039 compliance, we’ll talk you through options in the ForceField, Protec and Diamond ranges that can be matched to suit.
Look for the Manufacturing Compliance Label confirming it’s passed AS 5039 testing. We provide both, plus a compliance certificate on request.
