How Are Galvanized & Stainless Steel Different?Shea Bethell
If your business works with metal, you may have to choose between galvanized and stainless steel on some projects. These two varieties of steel might sound like interchangeable options — after all, they contain the same base material — but they have very different properties due to the way they’re processed. After reading the guide below, you’ll have a better understanding of the kind of steel you should purchase from Aluminium Trading for your next job.
What Is Galvanized Steel?
Galvanized steel material starts as standard steel: an alloy made of iron and carbon. It eventually undergoes a process known as hot-dipping, in which the steel is coated in zinc. This gives galvanized steel its shiny coat, which often causes people to mistake it for stainless steel. The primary benefit of this coating is rust-resistance.
For this reason, galvanized steel is often used for pipes and fittings, metal roofing, and chain link fencing. It’s a sensible choice for situations involving frequent weather or water exposure.
What Is Stainless Steel?
Unlike galvanized steel, which only really differs from normal steel by its zinc coating, stainless steel differentiates itself by having an altered composition.
To create stainless steel, liquid steel is combined with chromium to create a stronger product. Once it has cooled, it is treated with acid to remove impurities. The end product is rust-resistant and boasts higher strength than galvanized steel, however, the benefits come at a higher cost for the product. Stainless steel’s advantages make it better suited for industries that need its durability and strength, such as architecture and energy (such as nuclear and solar power stations).
