Darwin homeowners comparing security screens typically narrow the decision to two products: Crimsafe or 007 Security Screen. Both are sold and installed by DABSCO. Both meet AS 5039 — the Australian Standard for security screen doors and windows. Beyond that, they are genuinely different products built for different situations.

The comparison comes up constantly because the price gap is real, the performance gap is real in some conditions, and the right answer depends on what your property actually needs. A coastal Nightcliff home facing saltwater airflow is a different situation from a Palmerston rental property two streets from the highway.

DABSCO is Darwin’s Crimsafe certified installer, operating from 19 Swan Crescent, Winnellie, NT since 1966. The team installs both systems and carries no commercial reason to push one over the other. This guide explains how they differ, where each performs best, and which properties genuinely benefit from the premium product versus which ones the mid-range option suits just as well.

DABSCO can provide a free site measure across Darwin and Palmerston to assess which screen suits your openings.

How Crimsafe Is Built — and What That Means for Darwin Homes

Crimsafe is a premium security screen system manufactured by Crimsafe Security Products and installed through a certified network. The core technology is 304-grade Tensile-Tuff stainless steel mesh, clamped into an aluminium frame using a Screw-Clamp system at 125mm intervals with tamper-resistant screws. The mesh is 0.9mm strand thickness — 26.5% thicker than standard stainless mesh. Frames carry a Dulux-developed UV and corrosion-resistant powder coat. A cyclone-rated variant, Crimsafe Cyclone Debris, is tested to AS 1170.2 wind-borne debris standards. DABSCO holds the current Crimsafe certification for Darwin and the NT.

The full range of Crimsafe products and sizes available through DABSCO is covered in our Darwin Crimsafe installation guide.

How 007 Security Screen Is Made — and Where It Fits

007 Security Screen uses a 7mm aluminium grille mesh fixed into a powder-coated aluminium frame, manufactured to measure at DABSCO’s Winnellie facility. Every screen is made for the specific opening, not cut from stock. The product meets AS 5039 requirements, the Australian Standard for security screen doors and windows.

Standard powder coat colours cover most residential specifications. Special colours are available on request for projects where matching existing joinery or Colorbond cladding matters. The aluminium mesh is hard-wearing in most NT conditions, though it responds differently to coastal salt air compared to stainless steel mesh over the medium to long term.

A separate egress variant exists within the 007 range: the 007 Visisafe Safe-S-Cape. This is an emergency egress security screen that allows occupants to exit from inside without tools in an emergency. The Safe-S-Cape is exclusive to Crimsafe licensees like DABSCO — it is not available through non-licensed fabricators.

Durable aluminium mesh is the standard option. Other mesh types are available on request for specific project needs.

Crimsafe vs 007 — Head-to-Head Comparison

Where Crimsafe Has a Real Edge in Darwin — and Where It Doesn’t

Strengths

The 304 grade Tensile-Tuff mesh is the clearest technical differentiator. At 0.9mm strand thickness, it resists cutting and impact at a level that aluminium grilles cannot match. The Screw-Clamp fixing, applied every 125mm with tamper-resistant screws, means the mesh cannot be pulled away from the frame under pressure. When a panel takes a hit, the clamp mechanism distributes force around the frame perimeter rather than concentrating it at one fixing point.

For Darwin properties in cyclone wind regions, the Crimsafe Cyclone Debris variant adds a tested performance layer under AS 1170.2 conditions. The Dulux-developed coating is specifically formulated for UV and corrosion resistance, which matters in a climate with intense tropical sun and salt-laden coastal airflow. Crimsafe also provides a degree of fire attenuation by slowing radiant heat transfer.

DABSCO’s certified installer status means the manufacturer’s warranty applies in full. Some suppliers in Darwin fit Crimsafe without certification; that affects the warranty coverage a buyer receives.

For properties requiring the absolute highest level of impact and forced-entry resistance, Crimsafe Ultimate sits above the standard Crimsafe range and is available through DABSCO.

Honest Limitations

Crimsafe costs more than 007. For properties with many standard openings, the budget difference is significant. Not every window or door on every property requires the highest-performing screen available. Interior openings, low-traffic rooms, and properties in lower-risk locations may not justify the premium per panel. A mixed approach — using Crimsafe on the most exposed or high-priority openings and 007 on the rest — is a practical option many Darwin buyers choose.

H2: Where 007 Security Screen Performs Well — and Where It Falls Short

Strengths

007 Security Screen is a mid-range product that does its job well within its design parameters. It meets AS 5039, which is the compliance baseline required for insurance and regulatory purposes. Made-to-measure fabrication at DABSCO’s Winnellie workshop means fit quality is controlled locally, not dependent on a remote factory interpreting dimensions.

The 7mm aluminium grille construction is solid for most residential and commercial applications where coastal salt exposure is moderate and cyclone-rated mesh is not a priority. The powder coat colour range is broad enough to match most NT residential joinery without custom orders. For investor properties and rental housing where budget is a primary constraint, 007 gives compliant, functional security at a more accessible price point.

DABSCO’s in-house fabrication also means lead times are more controllable for 007 screens than products dependent on national supply chains.

Honest Limitations

Aluminium mesh performs differently from stainless steel in coastal Darwin conditions. Properties in Nightcliff, Fannie Bay, Rapid Creek, or Coconut Grove — where salt-laden air moves off the water regularly — can see aluminium grille show surface oxidation earlier than stainless. This does not immediately compromise structural integrity, but it does affect appearance and long-term corrosion resistance. Closer to the coast, the lifespan gap between 007 and Crimsafe widens.

007 Security Screen has no standard cyclone-rated variant. For homeowners specifically seeking wind-borne debris performance tested to AS 1170.2, the standard 007 range does not provide that. The 007 Visisafe Safe-S-Cape egress variant is available through DABSCO, but the main screen range does not carry cyclone certification.

H2: The Right Screen for Your Darwin Property — by Situation

The honest answer is that no single screen is correct for every situation. Here is a clear recommendation by property type.

Owner-occupier, coastal Darwin (Nightcliff, Fannie Bay, Coconut Grove, Rapid Creek)

Crimsafe is the better long-term investment. Salt-air corrosion accelerates aluminium grille degradation in these locations. The 304 grade stainless mesh and Dulux coating hold up substantially better over a 15–20 year ownership horizon. If budget is a constraint, prioritise Crimsafe on exposed coastal-facing openings and assess 007 for interior or sheltered openings.

Owner-occupier, suburban Darwin (Palmerston, Casuarina, Karama)

Either product is viable. Palmerston properties are further from direct coastal exposure, and the corrosion differential between stainless and aluminium mesh is less pronounced in these areas. Buyers who want maximum security performance and have the budget choose Crimsafe. Buyers optimising value for money often choose 007 and get a compliant, durable result.

Investor or rental property in Darwin

007 Security Screen is usually the practical choice. AS 5039 compliance is met, insurance and tenancy requirements are satisfied, and the lower cost per opening makes a meaningful difference across a multi-opening property. Coastal rental properties are the exception: closer to the water, the long-term maintenance cost difference may narrow the gap.

Cyclone-priority property

Crimsafe Cyclone Debris is the only tested option in either range for AS 1170.2 wind-borne debris performance. If cyclone screen performance is a primary concern for your property’s openings, the 007 standard range is not the right product. Discuss your property’s wind exposure with DABSCO before specifying.

Budget-constrained Darwin buyer

007 Security Screen is the right starting point. AS 5039 compliance is real, not nominal. A properly fabricated and installed 007 screen is a genuinely secure product. The budget reality in Darwin is that many homeowners cannot justify Crimsafe pricing across every opening, and 007 is not a second-rate compromise — it is a mid-range product that does what it claims.

Commercial property NT

Commercial projects often involve a mix. High-traffic entry doors may justify Crimsafe for impact resistance and warranty coverage. Office windows and less-exposed commercial openings can be specified with 007 to manage the project budget. Government and commercial tenders can be assessed through DABSCO’s tenders team at tenders@dabsco.com.au.

What DABSCO Actually Recommends After 60 Years of Darwin Installations

DABSCO sells and installs both products. The recommendation depends on what the property actually needs, not the product specified.

After 60 years of Darwin installations, the team has seen what different screen types do in different conditions. Coastal suburbs accelerate aluminium degradation. Elevated NT homes take different wind loads from suburban blocks. Some properties have openings where the highest-rated product is a sensible investment. Others have sheltered interior windows where that level of specification is unnecessary.

The most common recommendation DABSCO makes to Darwin homeowners is a mixed specification: Crimsafe on the most exposed, most critical, or highest-security openings, and 007 on secondary openings where the performance gap is less relevant. This gives the best outcome for the budget.

A written site measure lets DABSCO assess each opening individually and provide a comparison quote for both options. That quote gives buyers real figures to compare, not estimates. DABSCO can provide this across Darwin and Palmerston at no charge.

Frequently Asked Questions — Crimsafe vs 007 Darwin

Q1: Is Crimsafe or 007 better for a Darwin home?

Neither is unconditionally better — it depends on your property’s location and priorities. Crimsafe performs better in coastal Darwin suburbs like Nightcliff and Fannie Bay, where salt-air corrosion over time favours 304 grade stainless steel mesh over aluminium grille. 007 Security Screen is a solid mid-range choice for suburban Darwin and Palmerston properties, providing AS 5039 compliance at a more accessible price. DABSCO installs both and can assess your specific openings to give a clear recommendation rather than a generic answer. For most owner-occupiers, the choice comes down to coastal exposure, cyclone rating priorities, and budget per opening.

Q2: Is the 007 Security Screen cyclone rated in NT?

The standard 007 Security Screen range does not carry a cyclone rating tested to AS 1170.2 wind-borne debris standards. 007 screens are AS 5039 compliant as security screens, but are not certified for cyclone debris performance. If cyclone-rated screen performance is a priority for your Darwin property, Crimsafe Cyclone Debris is the relevant product in DABSCO’s range. That variant is specifically tested for wind-borne debris impact under NT cyclone conditions. For standard security compliance without cyclone-specific rating requirements, 007 meets the applicable Australian standard.

Q3: What is the price difference between Crimsafe and 007 Darwin?

As a general guide, 007 Security Screen is typically 25–40% less expensive than Crimsafe per opening, depending on screen size, configuration, and mesh specification. For a standard Darwin residential property with multiple openings, the total difference can be several thousand dollars. Crimsafe pricing reflects the Tensile-Tuff mesh, Screw-Clamp system, and certified installer warranty. 007 pricing reflects locally fabricated aluminium grille construction meeting AS 5039 at a lower input cost. DABSCO can provide a written side-by-side quote for both products on the same openings so buyers have real figures to compare. For a full breakdown of what to expect per opening, our guide to what security screens cost to supply and install in Darwin covers typical price ranges in detail.

Q4: Which security screen lasts longer in Darwin’s salt air?

Crimsafe, in most Darwin coastal conditions, has a longer practical service life than 007 Security Screen. The 304 grade Tensile-Tuff stainless steel mesh is significantly more resistant to salt-air corrosion than aluminium grille mesh. The Dulux-developed coating on Crimsafe frames also performs well under sustained UV and salt exposure. In suburbs like Nightcliff, Fannie Bay, and Coconut Grove — where sea-spray and salt-laden air are regular — the lifespan gap between the two products widens. Inland suburban Darwin and Palmerston properties see a smaller gap because corrosion pressure is lower. Both products last longer with occasional cleaning and maintenance.

Q5: Can DABSCO install both Crimsafe and 007 on the same property?

Yes. A mixed specification is common in Darwin and Palmerston. DABSCO installs both products and regularly provides quotes covering Crimsafe on priority or exposed openings alongside 007 on secondary or sheltered openings. This approach lets homeowners apply the higher-performing product where it matters most without paying the premium price on every opening in the house. For investor properties, a similar approach is sometimes used: Crimsafe on entry doors, 007 on standard windows. DABSCO can assess each opening individually during a site measure and price both options clearly.

Q6: Which screen is best for a Darwin rental investment property?

007 Security Screen is the most common choice for Darwin rental properties. It meets AS 5039 compliance, satisfies standard insurance and tenancy requirements, and costs less per opening than Crimsafe — which matters across a multi-opening investment property. For rental properties in coastal Darwin suburbs, the calculation is closer: aluminium grille degrades faster near salt air, which can mean earlier replacement. DABSCO can advise based on the property’s suburb and exposure. For investors wanting the lowest long-term maintenance cost in a coastal property, Crimsafe may be worth considering on the most exposed openings.

Q7: Is 007 Security Screen AS 5039 certified?

Yes. 007 Security Screen, as fabricated and installed by DABSCO, meets AS 5039 — the Australian Standard for security screen doors and windows. AS 5039 covers knife shear, impact, jemmy, and tensile tests. Compliance with this standard is required for most home insurance policies that specify security screens. 007 screens from DABSCO are manufactured to measure at the Winnellie workshop, so fit quality is controlled locally. Buyers should confirm that any security screen supplier they consider installs to AS 5039 standards — not all fabricators in the NT operate to this specification.

Q8: What is the 007 Visisafe Safe-S-Cape, and is it available in Darwin?

The 007 Visisafe Safe-S-Cape is an emergency egress security screen. It provides the security performance of a standard security screen while allowing occupants to exit from inside in an emergency without requiring tools or keys. This is relevant for bedrooms in particular, where a fixed screen would otherwise trap occupants during a fire or other emergency. The Safe-S-Cape is available through DABSCO in Darwin. Importantly, this product is exclusive to Crimsafe licensees — it cannot be purchased or installed through non-licensed security screen suppliers. DABSCO holds the current Crimsafe licensee status in NT.
