What Are Steel Coils?

Steel coils are long, thin sheets of steel that are used in a variety of applications. They are produced by rolling steel at high temperatures and can be found in a variety of industries, including construction, automotive, and appliances.

What Are Steel Coils Made Of?

Steel coils are made of a variety of different materials, including carbon steel, stainless steel, and aluminum. The type of material that is used depends on the intended application of the steel coil.

What Types of Steel Coils Are There?

When it comes to steel coils, there are a few different types that are commonly used. These include cold rolled, hot rolled, and coated steel coils. Let&#;s take a closer look at each type so you can better understand their uses.

Cold rolled steel coils are made from a hot rolled steel sheet that has been further processed to create a thinner, more pliable material. These coils are then either annealed or temper-rolled to achieve the desired properties. This type of steel coil is often used in the automotive industry for things like door panels and fenders.

Hot rolled steel coils are made from a red-hot steel sheet that is then passed through a set of rollers to achieve the desired thickness. These coils are often used in construction projects where a thicker steel coil is needed.

Coated steel coils are made by applying a coating to a hot rolled or cold rolled steel coil. This can be done using a number of different methods, such as hot dip galvanizing or electro-galvanizing. Coated steel coils are often used in the automotive and construction industries to protect against corrosion.

How Are Steel Coils Used?

Steel coils have a variety of applications, including in construction, automotive, and appliances. They are often used as structural components or as part of the exterior of buildings. In the construction industry, steel coils are used to create metal roofs, wall panels, and floor decks. In the automotive industry, steel coils are used to create car bodies and parts. In appliances, steel coils are used to create refrigerator doors and washing machine drums.

What Are the Benefits of Using Steel Coils?

There are many benefits to using steel coils. First, they&#;re super versatile, meaning that they can be used for a wide variety of applications. Second, they&#;re recyclable, making them an eco-friendly solution. Third, they&#;re cost-effective since they don&#;t cost you much but still last a long time. Finally, they&#;re easy to work with, being easily bendable, cuttable, and shaped for any needs.

Buying Better: The Definitive Cold Rolled Steel Gauge Chart

Cold-formed steel was first used in framing and construction around the s, both domestically in the United States and abroad in Great Britain. One of the first documented uses of cold-formed steel was the Virginia Baptist Hospital in Lynchburg, Virginia that was built around . 

Due to lack of design standards and little to no information on the product, acceptance of the material was limited until the &#;s when Lustron Homes built and sold almost 2,500 steel-frames homes, with the framing, finishes, cabinets and furniture made from cold-formed steel.

Cold-formed steel framed construction and homes are known for their longevity, strength, and resistance to harsh elements. This makes them ideal for even the most extreme environments and a notable sign of quality construction.

The first and most important rule of reading and understanding a steel gauge chart is using the right one. Meaning coated steel gauges like galvanized are vastly different from uncoated steel like hot rolled and cold rolled gauges. 

Standard gauge numbers and sizes were developed based on the weight of the sheet for a given material and coating. The equivalent thicknesses differ for each gauge number. You must use the specific gauge chart for each material to learn the right thickness. 

So, in this case, you&#;ll need the Cold Rolled Gauge Chart. 

Now that you have the right chart, it&#;s time to understand how it&#;s measured. Gauges are different from other measurement units such as inches or centimeters. That&#;s due to there being no universal thickness measurement for metal during the 19th century.

The British iron wire industry adopted metal gauges over other traditional units like inches as the primary unit of measurement, and thus it&#;s become the standard for the steel industry, being used across sheet metals.

When looking at a gauge chart, the key to understanding it, including our cold rolled chart, is to look at the number. Gauges range from 3-31, each has a specific thickness assigned to it for the material based upon its weight.

The general rule across all gauge charts is the larger the number, the thinner the steel. The inverse is also true, as the gauge number gets lower, the thicker the steel gets. But, those numbers do not give you specific dimensional values. Follow the chart for the exact numbers you need. 

If you&#;re looking for an even simpler solution to understanding the correct gauge, weight, width, and measurement conversions of any steel product, use our steel calculator Unravel.

Whether calculating gauges for cold rolled, hot rolled, and coated materials, looking for sheet metal or coil measurements, or just looking for unit conversion to inches and pounds, Unravel does the work for you.
