Why We Use Marine Grade 304 Stainless Steel

Durability. Performance. Built to Last.

At Heat Outdoors, we're committed to building heaters that stand the test of time, not just in function, but in form. That's why we use 304 stainless steel in many of our premium products. But what exactly is 304 stainless steel, and why is it the superior choice for outdoor heating?

What is 304 Stainless Steel?

304 stainless steel is a high-grade alloy made from a combination of iron, chromium (18%), and nickel (8%). This specific blend gives it a unique balance of strength, corrosion resistance, and workability - making it one of the most widely used stainless steels in the world.

304 is the gold standard for environments where hygiene, durability, and weather resistance are essential.

Why 304 Stainless Steel is the Best Choice for Outdoor Heating

• Exceptional Corrosion Resistance: Outdoor heaters face constant exposure to moisture, temperature fluctuations, and salt in the air, especially near the coast. 304 stainless steel is highly resistant to rust, oxidation, and corrosion, helping your heater maintain its appearance and performance, year after year.
• Strength and Durability: Whether it's intense heat, rough handling, or unpredictable weather, 304 stainless steel can take it. Its structural integrity doesn't degrade over time, ensuring your heater stays solid and secure in all seasons.
• Sleek, Stylish Finish: Aside from being tough, 304 stainless has a clean, polished look. It resists staining and discolouration far better than lower-grade materials, making it perfect for premium products that are always on show.
• Easy to Maintain: Unlike cheaper metals that can degrade quickly and need regular upkeep, 304 stainless is low maintenance. A quick wipe-down is often all it takes to keep it looking like new.
• Safe and Hygienic: This grade of stainless steel is non-porous and easy to clean, making it a popular choice not just for outdoor products, but also for kitchens, hospitals, and laboratories. That same hygiene standard is built into every 304 stainless component we use.
