Choosing between ForceField vs Protec vs Diamond comes down to two things: where you live (especially coastal vs inland Brisbane) and what you value most (views, budget, privacy, or maximum “set-and-forget” durability). This guide compares the three most popular Prowler Proof ranges we supply and install at Miza Security, across front doors, sliding doors, and security window screens.
Miza Security is an Australian owned business and company, established in the local security screen industry and committed to meeting Australian standards.
Introduction to Security Doors
Security doors are a cornerstone of home security in Australia, acting as the first line of defence against unwanted visitors and would-be intruders. Unlike standard doors, a security screen door is engineered to provide superior strength and protection while still letting you enjoy fresh air and natural light throughout your home. These doors are typically constructed from robust materials such as stainless steel mesh or a strong aluminium frame, ensuring both durability and visibility.
When selecting a security door, it’s important to look beyond just appearance. The best security doors are designed to withstand rigorous testing, including the dynamic impact test (simulating forceful kicks or hits), the knife shear test (resistance to cutting), and jemmy tests (protection against levering attacks). These tests are part of the Australian Standards, which set the benchmark for security, strength, and performance in the industry.
A well-chosen security door not only enhances your home’s protection but also allows you to keep your door open for airflow without compromising safety. Whether you’re looking to secure your front entry, sliding doors, or windows, investing in a quality security door made from steel or aluminium and tested to Australian Standards is a smart way to keep your home secure, comfortable, and filled with natural light.
Scope of this comparison
We’re comparing screens for:
-
Front door / main entry screen door
-
Sliding security doors
-
Windows / security window screens (including high airflow areas like kitchens and living rooms)
All three options can be custom-made and professionally installed, but the mesh/material and visual transparency are where the differences really show up.
Quick summary: choosing by your environment
-
Best for wide-open views + airflow (most “invisible” look): ForceField
-
Best for bayside / salt-air exposure + durability value: Protec
-
Best for tight budgets while staying security-rated: Diamond
Coastal note: Protec is specifically positioned as a great option for seaside homes (all-aluminium perforated sheet). ForceField and Protec have both gone through serious corrosion testing as complete screens.
Product overviews
ForceField security doors and screens (Prowler Proof)
ForceField is the premium option for households who want maximum visibility and natural light with high performance testing behind it.
What sets it apart:
-
Welded frame construction (not held together with screws or rivets) for strength and a cleaner finish
-
316 marine grade stainless steel mesh (often the deciding factor for people comparing stainless steel mesh vs aluminium)
-
Designed to look nearly invisible from a normal viewing distance (great for front doors and big living room openings)
Protec security screen door systems
Protec is the “smart security” pick when you want a tough screen with an all-aluminium build, especially in harsh weather or coastal suburbs.
What sets it apart:
-
Single sheet perforated aluminium construction (rigid, tough, consistent)
-
Developed as a great option for seaside homes
-
Has passed demanding corrosion testing (including acetic acid salt spray testing)
Hardware note: with any range, your real-world security also depends heavily on locks, hinges, and correct installation, especially on a front screen door that gets used constantly.
Diamond security screens
Diamond is the classic grille look, often chosen when budget matters, or when you want a more traditional “security door” appearance.
What sets it apart:
-
Designed by Prowler Proof as secure and economical
-
Still built with the Prowler Proof welded approach (no visible joints like many cheaper grille doors)
-
Tested. This is important, because many “diamond grille” doors sold elsewhere are not actually security-rated
Materials, construction, and door/screen options
Stainless steel mesh vs perforated aluminium
Here’s the plain-English version:
-
ForceField = stainless steel mesh (316 marine grade) → best when you want the most open feel and visibility.
-
Protec = perforated aluminium sheet → excellent durability and a strong choice in seaside conditions.
-
Diamond = grille style → economical, still security-rated when labelled correctly.
Custom made sizing
Security screens are not “one-size-fits-all”. For best results (and to stay compliant), you want an on-site measure and installation so the frame, locks, and fixings suit your specific door open / window opening.
Coastal recommendation
If you’re close to bayside air:
-
Protec is usually the first pick because it’s designed as a great option for seaside homes.
-
ForceField is also a strong option if you prioritise views – just make sure you keep up a sensible cleaning routine (salt film is relentless).
Security screen performance and testing
Australian Standards & National Security Screen Association
In Australia, there are stringent standards that cover security door and window screens (how they’re built, tested and installed).
Key tests to look for when comparing
When people ask “will this stop would-be intruders?”, this is what the standards-based testing is designed to cover:
-
Dynamic impact test (kicking/force)
-
Jemmy tests (levering at hinges/locks)
-
Pull & probe tests (forcing and tool gaps)
-
Knife shear test (mesh resistance to cutting)
-
Corrosion testing (long-term durability)
Diamond note: the knife shear test is treated differently for Diamond because the presence of the grille affects how that test is performed/meaningfully applied.
Fresh air, views, and insect protection
If your goal is “home secure, but not cave-like”:
-
ForceField tends to feel the most open visually (more natural light, clearer outlook).
-
Protec can feel slightly more private because it’s a perforated sheet.
-
Diamond is the most visually obvious (grille look), but still allows airflow.
All of these screens protect your home and family from insects, intruders, and environmental elements, providing security, privacy, and comfort.
These screens also provide peace by offering safety and reducing insect intrusion.
Home Security Solutions
A comprehensive home security solution goes beyond just a single door, it’s about creating layers of protection and peace of mind for your family. Security doors and security screens are at the heart of this approach, offering a strong physical barrier that deters intruders while still allowing you to enjoy the benefits of fresh air and natural light.
When choosing the right security solution, consider the materials and features that best suit your needs. For example, a security screen door made with 316 marine grade stainless steel mesh and a triple lock system delivers superior strength and resistance to forced entry. Aluminium frame options also provide excellent durability, especially in harsh or coastal environments. Professional installation is essential to ensure your security doors and screens are fitted perfectly, maximising their effectiveness and longevity.
High-quality window screens made from marine grade stainless steel or aluminium add another layer of protection, especially for vulnerable entry points.
By investing in well-designed security doors, robust locks, and professionally installed screens, you’re not just protecting your property, you’re providing complete peace of mind for your household. Quality security solutions are an investment in your family’s safety, comfort, and the overall value of your home.
Front door, locking hardware, and real-world security
For high-traffic entry doors:
-
Prioritise quality locks (triple point locks are a good for extra security)
-
Make sure the frame reinforcement and fixings match your doorway and usage
-
Choose a style you’ll actually keep closed and locked (sounds obvious… but it’s important)
A great product can be compromised by poor installation, so always look for proper licensing and process. A professional installation ensures the job is completed to the highest standard, resulting in reliable security and customer satisfaction.
Corrosion, maintenance, and cleaning
Brisbane conditions = humidity, storms, and (in many suburbs) salt carried inland.
General best practice:
-
Rinse screens periodically with fresh water, especially after harsh weather.
-
Don’t use harsh abrasives or aggressive chemicals.
-
If you’re coastal, ask us about a simple service schedule so your doors and screens keep performing smoothly.
Prowler Proof backs corrosion resistance with specific testing, including neutral salt spray and (for ForceField/Protec) acetic acid salt spray testing.
Warranties, certification, and aftercare
Two big trust anchors we point customers to:
-
10-year full replacement warranty (replacement rather than a repair-only approach)
-
QBCC licensed installer
Pricing and value comparison
We always recommend comparing long-term value, not just the upfront quote:
-
expected exposure (bayside vs inland)
-
how important views are
-
usage level
-
warranty and aftercare support
The “best” option is the one that fits your house and your risk profile without compromising how you want to live in the space.
FAQ
What’s the difference between 316 stainless and perforated aluminium?
316 marine grade stainless steel mesh (ForceField) is chosen for strength and visibility, while perforated aluminium (Protec) is a solid sheet design often favoured for seaside durability and a slightly more private look.
Are Diamond screens compliant?
They can be, but only if they’re properly tested. Prowler Proof specifically distinguishes their diamond product as high quaity given many diamond grille products on the market are not security compliant, while theirs are tested/labelled and have corner welds for strength.
Which is best near the bayside?
Most bayside customers lean Protec because it’s explicitly positioned as a great option for seaside homes and has passed tough corrosion testing. ForceField is also strong if views are the priority, provided you maintain it sensibly.
Final recommendation (by household type)
-
Families who want the best views + complete peace: ForceField on primary doors and main living areas.
-
Bayside / salt-air homes that want tough, great-value security: Protec across doors and windows.
-
Budget-led upgrades that still need a security-rated screen: Diamond, correctly specified and labelled.
