Stainless steel gets used in food processing, medical work, labs, factories and construction, and for good reasons. These are the main ones.
It lasts
It doesn't rust easily. Stainless resists corrosion and rust, even around moisture, chemicals and extreme temperatures, so the parts and structures made from it last longer.
It's strong for its weight. It gives you a strong, durable part without a lot of extra weight, which is why construction, automotive and aerospace work all rely on it.
It handles heat and chemicals. Stainless keeps its strength at high temperatures, so it suits industrial ovens and exhaust systems. It also stands up to a wide range of chemicals, which is why labs and processing plants use it.
It's clean and safe
It's easy to keep clean. The surface isn't porous, so it cleans and sanitises easily. That's why food processing, medical and pharmaceutical work uses so much of it.
It's safe around food and water. It doesn't release harmful substances or react with other materials, so it's used for medical devices, food containers and water treatment.
It's worth the money
It can be made into almost anything. Stainless can be fabricated into simple brackets, complex assemblies and everything in between.
It pays for itself. It can cost more up front than other materials, but it lasts longer and needs less maintenance, so it usually works out cheaper over time.
It looks good and it recycles. It keeps a clean finish for years, and it's 100% recyclable.
