When it comes to choosing the right stainless steel for your swimming pool handrail, not all grades are created equal. At Hand Rails Australia, every one of our rails is made from 316 marine-grade stainless steel, crafted locally on the Gold Coast using premium materials from Stirlings Australia.
Why does this matter? Because your pool environment — with its salt, chlorine, and humidity — demands the best possible protection against corrosion and rust.
Let’s break down the key differences between 304 and 316 stainless steel, and why 316 is the clear choice for pools and coastal homes.
🔹 What is 304 Stainless Steel?
304 stainless steel is a common, affordable alloy often used in kitchen appliances, indoor fittings, and decorative applications. It’s durable for dry or indoor use, but it’s not designed for constant exposure to moisture, salt, or chlorine.
When 304 steel is used outdoors — especially around pools or near the coast — it can begin to show signs of rust and tea staining within just a few months. These brown discolourations don’t just affect appearance; they can also weaken the metal over time.
So, while 304 might seem like a cost-saving choice upfront, it simply isn’t made to handle Australian outdoor conditions.
🔹 What Makes 316 Stainless Steel Better?
316 stainless steel — also known as marine-grade stainless steel — contains an important added ingredient: molybdenum. This element dramatically increases resistance to corrosion, salt, and chemicals like chlorine.
That’s why it’s the same grade used in marine environments, coastal architecture, and professional pool fittings.
316L (the low-carbon version we use at Hand Rails Australia) goes one step further — offering enhanced strength and resistance to pitting, making it the gold standard for long-lasting outdoor fixtures.
✅ Perfect for pool areas, coastal homes, and resorts
✅ Highly resistant to rust and tea staining
✅ Stronger and longer-lasting than 304 stainless steel
