Sheet metal serves a variety of purposes such as fences, furniture, automobiles, as well as computers. Sheet metal is flat, allowing the manufacturer to create rolls of the material, yet not so thin that it rips easily like metal foil.
There are different types of sheet metal categorized by their alloy, thickness, and then further classified by their hardness, method of manufacturing, tensile strength, and quality. With all these different factors affecting quality and use, there several types of sheet steel from companies like WasatchSteel.com in the market.
Cold-rolled steel creation follows a process that begins with placing the metal alloy in between two rollers, one on top and the other on the bottom, to deform the metal into a thinner piece, or sheet, than its original size. It has a more homogeneous composition, which allows better conductivity of heat and is easier to shape using a machine.
Using this type has a lot of benefits, but there are things you need to know about cold-rolled steel before using it.
Hot-rolled steel goes through the rolling process at temperatures more than 1,400 degrees Fahrenheit or higher. Manufacturers use saturated pits of induction heating to raise the temperature of the metal before rolling the piece to get the desired size.
Mild steel is a different kind of cold-rolled steel. The steel alloy in this process contains less carbon than other steel sheet metals, and as a result this type reacts well to manipulation such as welding or arrangement. Body panels of automobiles often contain mild steel as it is easy to mold and form.
This type usually contains other metals, such as copper, zinc, manganese, silicon, or magnesium. This kind of metal sheet is naturally soft, that is why manufacturers include elements such as iron, silicon, copper or magnesium to increase its strength. Aluminum sheet metal has many purposes, such as jewelry, fan blades, electronic chassis, and household appliances.
There are other types of sheet metals, but knowing the basics gives you an idea on which to use based on your needs.
