The primary function of security mesh doors is safety. Yes, you’ll want to select security doors that match the look and feel of your home. Although, what good are they if they won’t withstand the test of time?
So, I hear you asking… Do I need a stainless steel security door? What are the benefits?
Stainless Steels vs Milder Steels – Corrosion Resistance
“Stainless steel” is a general term that refers to a group of corrosion-resistant steel alloys that consist of at least 10.5% chromium.
The chromium-rich oxide film found on stainless steel occurs near the surface of the material and allows it to have a higher resistance to corrosion when compared to milder steel. This acutely thin and invisible film adheres tightly to the metal and has the ability to self-repair when it suffers from abrasion, machining or cutting.
Grades of Stainless Steel
As you start researching stainless steel security mesh doors, you’ll likely come across doors with a 304 or 316 stainless steel grade. So how do they differ?
304 grade is the most common form of stainless steel security mesh doors. While still offering resistance to corrosion and good value for money, 304-grade steel can become tea stained, pitted, or even deteriorate, mainly if your property is within 5 km of the ocean.
For this reason, 316-grade stainless steel security doors are the preferred choice for coastal homes, commercial buildings, jetties and piers. 316 steel will resist ordinary rusting, pitting and crevice corrosion, providing peace of mind that your security mesh door will stand the test of time.

Absolutely love my new doors and the service is fantastic, while fitting my new front doors I’ve had my back door measured up and look forward to having that replaced in the near future. Update: I now have back door and decided to also have my windows completed and I’m beyond happy! Communication is exceptional, service is absolutely amazing! And my house looks beautiful! Thank you KNA!
