Crimsafe Colonial Castings
If you want a security door that adds genuine street appeal without giving up AS 5039 protection, Crimsafe Colonial Castings is worth a close look. DABSCO supplies and installs Colonial Casting panels as part of a Crimsafe security door system from its licensed fabrication facility in Winnellie. The panels are gravity die cast in 100 per cent recyclable aluminium, which means no rust, no corrosion, and no structural degradation from Darwin’s coastal salt air or wet season humidity. They suit both sliding and hinged door configurations, and every unit is built to measure.
What Are Crimsafe Colonial Castings?
Colonial Castings are decorative cast aluminium door panels manufactured by an Australian company that has been producing this product since 1947. The inserts slot into extruded aluminium door frames and are available in a wide selection of traditional and contemporary design patterns. When combined with a Crimsafe security door system, the Colonial Casting panel replaces the standard appearance of a security door with something that looks more like a quality feature entry or a heritage-style screen door.
The panels themselves add no additional security rating. Their purpose is entirely aesthetic. The security performance of the door comes from the Crimsafe Screw-Clamp system and AS 5039-compliant frame and lock hardware. This is an important distinction: the casting is the face of the door, not its structural defence.
For Darwin homes, particularly older-style elevated houses in Parap, Larrakeyah, or Stuart Park, Colonial Castings fit naturally with the architectural character of the property without the clinical look of standard stainless mesh doors.
Compatibility with Crimsafe Security Doors
Colonial Casting panels can be added to a Crimsafe security door in two ways. They can be incorporated into a Crimsafe Safety Screen Door, which provides a lower level of security than a full Crimsafe Ultimate door but still meets the requirements of AS 5039 for security screen doors and window grilles. They can also be added to a full Crimsafe security door where the casting is used as the external decorative layer over the Crimsafe Tensile-Tuff mesh frame.
Both sliding and hinged door applications are supported. DABSCO’s Winnellie fabrication team builds these doors locally, which means lead times are shorter than sourcing interstate and any custom sizing for Darwin’s older door openings, which rarely match standard dimensions, can be managed on-site.
All Crimsafe doors supplied by DABSCO include triple-point locking and bug seals as standard, which matters in the build-up when insects are present in high numbers, and any gap around a door frame is an entry point. AS 5040 governs installation requirements for security screen doors, and DABSCO’s licensed installer status ensures compliance at the point of fitting, not just the point of manufacture. You can review the installation standard requirements through the Australian Building Codes Board.
Powder Coated Finish and Darwin Climate Durability
The Colonial Castings powder coat range covers the full Colorbond colour palette. For Darwin conditions, colour selection is more than a style decision. Darker powder coat finishes absorb significantly more radiant heat, which affects surface temperature on west-facing entries during the dry season afternoon sun. Lighter finishes or mid-range tones perform better on exposed elevations.
The powder coat on Colonial Casting panels carries a 24-month manufacturer’s guarantee. Maintenance in the tropics is straightforward: a periodic wash-down with fresh water removes the salt, dust, and wet-season mould growth that accumulates on any external surface in Darwin. The gravity die-cast aluminium construction means there is no ferrous material in the panel to rust, which gives it a practical service life advantage over any steel-based door component in a coastal or riverine Darwin suburb.
DABSCO can match Colonial Casting frames to other powder coat colours used across a window and door package, which is worth discussing at the measure and quote stage if you are doing a full house fit-out.
Security Performance in Wind Region C
Darwin sits in Wind Region C under AS/NZS 1170.2, which sets the structural loading requirements for all external fixtures, including security doors. Crimsafe security doors are independently tested to withstand impact forces well above the minimum 100 joule requirement set in AS 5041. Many standard competitor products fail to meet even this minimum threshold, as demonstrated through independent testing conducted at the University of New South Wales at the Australian Defence Force Academy.
A Colonial Casting door combined with the Crimsafe system should be assessed against the wind load requirements of its specific installation location. Ground-level doors on a fully exposed coastal Darwin property face different structural demands than a door sheltered under a deep overhang. DABSCO’s measure and quote process covers this assessment. Crimsafe product technical specifications are published at Crimsafe product technical specifications for reference.
Ventilation and Insect Control in the Wet Season
Security doors in Darwin do real year-round work. Through the wet season and the build-up, the combination of heat, humidity, and insects means that solid doors are rarely practical during daylight hours. A Colonial Casting security door allows a home to remain ventilated through the main entry while maintaining a physical security barrier. This is the same principle that makes security screen windows effective in Darwin bedrooms through the overnight hours.
For properties on acreages around Humpty Doo or rural Palmerston, where insect pressure during the wet can be intense, the bug seal integrated into Crimsafe door frames reduces the gap between door and frame that insects exploit in standard screen installations. This is a detail that matters operationally, not just aesthetically.
NCC Section J energy compliance for Darwin homes also recognises natural ventilation as a primary cooling mechanism. A door that can remain open to airflow while maintaining security contributes to the whole-of-house passive cooling performance. The NCC requirements are available through the National Construction Code portal.

Frequently Asked Questions
Do Crimsafe Colonial Castings meet Australian security screen standards?
When incorporated into a Crimsafe door system, the complete door assembly meets AS 5039. The casting panel itself is decorative. Security performance comes from the Crimsafe frame, mesh, and locking hardware.

Can Colonial Casting doors be made as sliding doors in Darwin?
Yes. DABSCO fabricates Colonial Casting panels into both sliding and hinged door configurations from the Winnellie workshop. Sliding installations suit Darwin homes where a hinged door would obstruct a narrow veranda.

Are these doors suitable for Darwin’s coastal salt air environment?
Yes. Gravity die-cast aluminium does not rust. Combined with powder-coat finish and stainless mesh hardware, the assembly is well-suited to coastal Darwin suburbs, including Fannie Bay, Nightcliff, and Cullen Bay.

How hard is it to maintain a Colonial Casting door in the tropics?
Minimal. Wash the cast panels with fresh water periodically to remove salt and mould build-up. No painting or sealing is required. The powder coat requires no ongoing treatment beyond cleaning.

Can I match the Colonial Casting colour to my other DABSCO windows and doors?
Yes. Powder coat colours can be matched across a full window and door package. Raise this at your measure and quote, and DABSCO’s team can confirm colour options and lead times.

Are Colonial Casting doors cyclone-rated?
Crimsafe doors are built to withstand significant structural loads. Any door installed in a Wind Region C location should be assessed for its specific opening and exposure. DABSCO’s measure and quote process includes this review for Darwin and Palmerston properties.

How long does installation take for a Darwin property?
Most single-door replacements are completed in a single visit. Custom sizes or properties with non-standard openings may require a fabrication lead time. DABSCO fabricates locally in Winnellie, which keeps Darwin lead times shorter than interstate supply chains.
