FAQ
1. What is SPA-H steel?
SPA H Steel, also known as weathering steel, is a high-strength low-alloy steel that exhibits excellent resistance to atmospheric corrosion. It is classified as a low-alloy structural steel, primarily alloyed with copper, chromium, and nickel, which contribute to its unique properties.
2. Why is corten steel so expensive?
Corten steel is more expensive due to the materials used and the specialized production process. Traditional steel rusts and is therefore a less suitable choice for outdoor applications. Polyester is cheaper than corten steel, but does not withstand temperature changes as well and can become porous over time.
3. How long will corten steel last?
Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.
4. How to tell if steel is Corten?
Corten Steel undergoes a gradual weathering process so that you may notice signs of ageing, such as rust accumulation and colour changes over time. These visual cues indicate that the steel is indeed Corten and not a standard steel with surface rust.
5. Do magnets stick to corten steel?
The 316 and 304 stainless steel that we sell is austenitic and therefore will not attract magnets. Which Steels are Magnetic? Other than austenitic stainless steels, most steel does attract magnets. Galvanised steel, Corten steel, mild steel, cold-reduced steel and hot-rolled steel are all magnetic.
