Galvanized VS. Stainless Steel

Galvanized VS. Stainless Steel

Steel isn't all the same Though both materials are steel, galvanized steel and stainless steel are very different materials that have a variety of applications. Knowing the difference is important, especially when given the choice of which material to use when tackling a home improvement or construction project. Galvanized steel is steel that is coated in a thin layer of zinc to help prevent corrosion.

The zinc may be applied to the steel through a process of hot-dipping or electrogalvanizing. Hot-dipped steel is steel that is dipped into a hot bath of liquid zinc. It is then removed and allowed to dry. The zinc coating adheres to the steel as it cools, creating galvanized steel. Galvanized steel is a common material for home construction projects. It is often used in framing homes. Nails, nuts and bolts are made from galvanized steel. It is also a popular option for ornamental fencing. What is thought to be iron fencing is often galvanized steel tubing. It is preferred due to its ability to resist rust. Stainless steel is made when a concentration of chromium of at least 10 percent is added to molten steel. The steel, in its liquid state, is poured, pressed or formed. When it cools and hardens, stainless steel is formed. The hardened steel is also subjected to acid treatments, called pickling, which remove any impurities on the surface of the steel, and passivisation, which forms a noncorrosive layer on the surface of the steel. Stainless steel is the primary metal used in construction. It is particularly attractive for building applications because of its strength and resistance to rust. Skyscrapers are framed with it and homes are constructed with it. Stainless steel is used to manufacture pipe for building as well as plumbing. It is used for most hardware, hand tools and saw blades. Stainless steel should not be used when any two pieces have the potential to rub together. Friction may break down the oxide layer of the steel and the pieces may actually weld together.
