Not All Security Door Are Equal — And the Wrong Choice Leaves You Less Protected Than You Think
Drive through any Adelaide suburb, and you’ll spot security doors on nearly every second home. But not all of them are doing what homeowners think they are. Many products sold as security doors offer little more than the appearance of protection — lightweight frames, uncertified mesh, and single-point locks that an intruder could defeat in seconds.
If you’re investing in a security door for your Adelaide home, understanding what really counts and what’s just marketing is the key between being able to rest easy or merely think that you are. Take a look at these things you should consider before purchasing.
What Is a Security Door?
A security door is a reinforced door fitted to the exterior entry points of a home or business — designed to allow ventilation and visibility while resisting forced entry. In contrast to ordinary fly screen doors, security doors are made from heavy-duty frames, security-approved mesh or solid steel sheets, and a multiple-locking system that complies with the safety standards of Australia.
They have two functions: first, they exclude insects like flies, and second, they provide a physical deterrent to any intruder, just as a fly screen door would do. Quality security doors are independently tested and certified — not simply marketed as secure based on appearance alone.
What Makes a Security Door Actually Secure?
1. Australian Standard AS5039 Certification
This is the non-negotiable starting point. AS5039 is the national standard for security screen doors and windows — covering mesh strength, frame integrity, lock performance, and resistance to knife attack, impact, and jemmy force.
Any reputable supplier of security doors will provide proof of AS5039 compliance upfront. If a supplier can’t produce it, that’s a clear signal to look elsewhere.
2. Security-Grade Mesh
The mesh is where most of the protection actually happens. There are three main options worth knowing:
- Stainless steel mesh is the strongest available — virtually impossible to cut or puncture, and it holds up well in Adelaide’s coastal and variable climate conditions. It’s the recommended choice for front entries and any opening you consider high priority.
- Aluminium security mesh is lighter and more affordable while still offering significantly greater strength than standard fly screen mesh. A solid choice for side and rear entries in most residential situations.
- Perforated steel panels are used where maximum rigidity is the priority over visibility — common in commercial security doors and high-security residential applications where appearance is secondary to performance.
Standard insect mesh, regardless of how it’s framed, should never be treated as a security option.
3. Multi-Point Locking Systems
Most forced entries through doors happen at the lock. A high-quality security door utilises a multi-point locking mechanism whereby the locking action takes place on three or more points of the frame at the same time, thus reducing the risk of kicking or levering in comparison to a single deadbolt.
The locking mechanism should also be keyed-alike where possible, ensuring convenient operation without carrying different keys around.
4. Frame Construction and Installation
Even a fully certified door with premium mesh will underperform if it’s not correctly installed. Security door installation requires anchoring the frame directly into the structural wall — not surface-mounting to brickwork or exterior cladding.
Improper installation of security doors is one of the most overlooked failure points. The door itself passes every test, but under real force the frame pulls away from the wall. Professional installation by an experienced team ensures the door performs exactly as its certification promises.
Residential and Commercial Options
For most homeowners, a certified residential security door with stainless steel or aluminium mesh covers every practical need. Commercial security doors are built to a higher specification — heavier gauge materials, reinforced frames, and higher-rated hardware — designed for business premises, rental properties, and high-traffic entries where demands are greater.
Adelaide Custom Blinds supplies both. Whether you need custom security doors for a single home entry or a commercial fit-out across multiple premises, every door is made to your exact measurements and installed by our professional team.
FAQs
Q: What is AS5039 and why does it matter?
AS5039 is Australia’s national standard for security screen doors. It independently verifies that a door can resist forced entry — without it, there’s no proof the door performs as claimed.
Q: What mesh type should I choose for my front door?
Stainless steel mesh is the strongest and most durable option — recommended for front entries and any opening you consider high priority.
Q: Can security doors be made for non-standard openings?
Yes. Adelaide Custom Blinds manufactures custom security doors to your exact dimensions, including oversized, arched, and non-standard frames.
Q: What is the difference between residential and commercial security doors?
Commercial security doors use heavier materials and higher-rated hardware designed for frequent use and greater security demands — suitable for businesses, rental properties, and high-traffic entries.
Q: How long does installation take?
Most installations are completed in a single visit of 1–2 hours, with jobs typically ready within 1–2 weeks of the initial measure.
Conclusion
Choosing the right security door comes down to four things: AS5039 certification, the right mesh for your entry point, a reliable multi-point locking system, and professional installation that anchors the frame correctly.
