When it comes to protecting your property, a steel security door offers a powerful blend of strength, safety, and style. Whether you're upgrading your main entry or securing a side or rear access point, selecting the right door is essential for peace of mind.
1. Understand Your Security Requirements
Before you choose a door, assess your specific needs:
- Are you in a high-risk area?
- Do you need a solution for residential or light commercial use?
- Is weather or impact resistance also important?
If you're unsure, explore our Sentry Security Personal Access Doors to see examples designed for both durability and safety.
2. Prioritise High-Quality Materials
Not all steel doors are made equal. Look for:
- Galvanised steel construction for corrosion resistance
- Reinforced frames for added strength
- Powder-coated finishes for long-lasting visual appeal
Extra Protection, Built In – Sentry Protect
Larnec’s Sentry Protect is an additional finish applied to your steel security door, creating a tough, corrosion-resistant barrier against the elements. Ideal for coastal, wet, or high-wear environments, this added layer helps prevent rust and extends the life of your door—keeping it looking and performing at its best for years to come.
Our steel security doors are manufactured in Australia and built to withstand the toughest conditions.
3. Consider Installation & Fit
A properly installed security door should:
- Fit flush within the frame
- Be pre-hung in a steel door frame for easier installation
- Leave no gaps for tampering
Larnec’s pre-hung steel doors are designed to ensure quick, hassle-free installation.
4. Don’t Sacrifice Design for Safety
Today’s security doors combine toughness with modern aesthetics. Choose from:
- Flush or panel styles
- Vision panels and mesh inserts
- Fire-rated or cyclone-rated features for added protection
Explore our Sentry Series to discover doors that are as stylish as they are secure.
5. Check for Australian Standards Compliance
Always ensure the door meets relevant standards:
- AS5039 (security screen doors)
- AS1905.1 (fire door sets)
- Wind ratings where applicable
Larnec doors, wall hatches and vents are designed, engineered, manufactured and tested to meet or exceed Australian compliance requirements.
