Which is better, steel or aluminium for security doors?
Aluminium is better than steel for security doors in Wollongong & Illawarra. Aluminium security doors are strong & sturdy, they do not rust, they come in a wide range of styles and finishes and due to their light build, are easier to install. Let’s break down why aluminium is the better option for security doors on coastal homes.
Aluminium Security Doors:
For coastal areas and homes near the beach, aluminium is your best option! It simply won't rust, making it the perfect low-fuss option. Aluminium doors are easier to install and handle. They are available in a wide range of finishes and styles. They don’t require much maintenance. They might not be as sturdy as steel, but they still offer fantastic impact resistance.
Steel Security Doors:
Steel doors are known for strength and durability. Their extremely heavy-duty construction makes them high impact-resistant. Steel doors often feature coatings to resist rust, these coatings require more maintenance, especially for coastal homes. Steel is also extra heavy, so expect higher install costs, and make sure your door frame is extra sturdy. For these reasons, we don’t do steel security doors, and opt for aluminium instead.
Comparison Table
| Feature | Steel Doors | Aluminium Doors |
|---|---|---|
| Strength | Very strong, high impact resistance | Good strength, good impact resistant |
| Weight | Heavier, requires strong framing | Lightweight and easy to handle |
| Corrosion Resistance | Susceptible to rust if not treated | Naturally corrosion-resistant |
| Maintenance | Requires regular maintenance | Low maintenance |
| Cost | Generally higher | Often more affordable |
| Style Options | Limited due to rigidity | Wide variety of finishes and styles |
Cost Analysis
Steel has a higher retail price. You're paying for extra strength, and the heavier product creates a more involved installation process. Aluminum is generally a lower retail price, lighter, easier to install, and is lower maintenance long term. Meaning aluminium is the better alternative when it comes to price.
Keep in mind that while steel is tough, its long-term maintenance costs will add up, especially for those that live near the beach, needing regular repainting and maintenance.
Maintenance Tips
Steel Doors: Check for rust spots regularly and touch them up or repaint as needed. Always lubricate the locks and hinges.
Aluminium Doors: A simple wash with mild detergent every now and then is enough to clear away salt or grime. Check for deep scratches and touch them up as needed to keep them looking good as new.
Which Should You Choose?
For easy low-maintenance, corrosion resistance, good impact resistance, and a range of designs, aluminium is the way to go. For those wanting seriously high impact control, don’t mind higher maintenance and costs, steel is a good choice.
Ultimately, your choice depends on your home's location, security requirements, and budget. Consulting with local experts can help you select a door that balances strength, style, and durability to suit your needs.
