Premium Hills District Security Doors, Screens, Windows & Grilles (Bars)

Get A Free Quote

Warm afternoons call for open doors and windows, while the hours after dark call for everything shut. Security doors and screens made for your openings give you both.

At OnGuard Security Products, we manufacture security doors, screens, windows and grilles (bars) for Hills District homes and businesses. Each suits its opening and the building around it.

Why Choose Our Security Doors & Screens?

A security product is only as good as its weakest part, from the mesh to the frame fittings. That’s why we build every element to carry its load.

Strength starts with compliance. Hills District security doors and screens in our range meet Australian Standards for security and durability.

Built for Strength: Our security doors are made to meet Australian Standards, giving you confidence in their durability and performance.
Custom-Made Designs: We offer a range of styles and finishes, so your doors and screens can be matched to your property.
Advanced Security Features: Reinforced frames, high-tensile steel mesh, and multi-point locking systems help improve resistance against forced entry.
Sliding Security Screen Doors: A practical option for areas where space matters, allowing easy access without compromising protection.
Security Screen Doors: Designed to provide a secure barrier while still allowing airflow and visibility.
Security Window Screens: Custom-fitted to reinforce windows while maintaining ventilation and natural light.

All Products Made to Order

Every product is made to order, putting the design choice in your hands. Styles and finishes are broad enough to follow the character of your home or commercial space.

Under the finish sits the hardware doing the heavy lifting. Reinforced frames, high-tensile steel mesh and multi-point locking systems spread resistance so force at one point meets strength throughout.

Patios, balconies and rear entries rarely have floor space to spare. Our sliding security screen doors travel along the opening instead of swinging inward, keeping the walkway clear.

Front and back entries need a barrier that holds firm yet feels welcoming. Our security screen doors put strength across the doorway and leave your view and breeze untouched.

Security Doors and Screens for All Windows

Windows deserve the same attention, particularly the quieter ones down the side and out back. Hills District security screens are custom-fitted to each opening, so daylight and airflow continue.

Marine-grade aluminium and stainless steel mesh run through the range, chosen for strength and resistance to corrosion. Security lasts, and the finish holds its appearance years later.

Locks and fittings decide how a door feels every day, long after the frame is bolted in. Our Inner West Sydney locksmith matches hardware to the product, so it moves freely and latches firmly.

 Trustindex verifies that the original source of the review is Google. Paul, I must say what an amazing job. Was not expecting the quality of the finished product which is fantastic. As mentioned you undersell the product. It is of the highest quality and workmanship. Customer service is terrific with arriving promptly to install. All I can say is wow. Would highly recommend anyone looking for a superior, high quality pool pump enclosure. A++

There is no sleek marketing here, Paola simply provides a quality product, great service, exceptional delivery and timely installation. What a refreshing change.

Cannot recommend highly enough.

Security Solutions for Hills District Homes and Businesses

Security works best across the whole building, not one entrance. Decorative security doors and custom screens can be drawn up for a contemporary build or a period facade, while window screens reinforce the openings that go unnoticed. When insects are the nuisance, our Inner West Sydney fly screens let you leave doors and windows wide open.

Commercial premises face heavier use, so ours are built for constant traffic and clear deterrence at shopfronts, offices and warehouses. Security window screens and grilles cover exposed openings while your team keeps the visibility a working day needs. Our Inner West Sydney aluminium gates then handle the perimeter, holding driveways, side paths and boundary lines behind a matching finish.

Energy Efficiency & Added Benefits

Protection is only part of what our security products do. Our security doors and screen doors add a layer of insulation that helps hold indoor temperatures steady and keeps energy costs down, while the mesh lets fresh air through and holds back heat and UV.

Comfort is the other half of it. Insects stay outside and harsh weather is kept at bay, so your home stays secure and liveable through every season.

Frequently Asked Questions

What are the benefits of installing security doors and screens?

Security doors and screens protect your openings and still allow ventilation whenever the weather suits. They deter intruders, resist force and hold back insects and harsh weather.

Window screens extend that protection to openings which are easy to overlook, preventing forced entry while airflow continues. Reduced heat transfer through the mesh also supports energy efficiency.

What materials are used in security doors, screens and windows?

Two materials do most of the work in our security doors, screens and windows: high-strength aluminium for the frames and premium stainless steel for the mesh. Between them, they deliver durability, corrosion resistance and long-term protection.

Sites that want extra reinforcement can order custom security doors with strengthened frames and multi-point locking. The same frames and mesh go into our security screens for windows.

Can security doors and screens be customised to match my home’s style?

Yes. Our security doors and screens are made to order, so the design is yours from the frame profile to the colour and finish. Contemporary and traditional exteriors are both catered for.

The mesh itself is a decision too. Our screen doors and security window screens come in several mesh styles, balancing protection against a clear view.

Do your security doors and screens meet Australian Standards?

Yes. Our security doors and screens comply with Australian Standards AS5039-2008 and AS5041-2003, which set what a security product must withstand.

Our security window screens are built to the same standards, so homes and commercial sites get consistent protection.

What maintenance is required for security doors and screens?

Hardly any. Our security doors and screens, sliding models included, need little more than an occasional clean with mild soapy water to clear the frames and mesh.

Abrasive cleaners are the one thing to avoid, since they can mark mesh panels and security window grilles. That simple routine keeps everything performing and looking the part.

Do security doors and screens improve energy efficiency?

Yes. Our security doors and screens support energy efficiency by adding insulation and letting airflow do work a cooling system would otherwise take on. Direct sunlight is held back too.

Cross-ventilation is where screen doors, sliding security screen doors and security window screens earn their place. Cooler summers and steadier winter warmth indoors mean your heating and cooling have less to do.
