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.

Metal is used for many applications ranging from manufacturing vehicle parts and industrial equipment to building bridges and structures. These components begin as raw metal material that is molded or extruded into standard shapes and sizes, like sheets or bars, that are further formed or shaped into finished parts.
Here we will look at what bar stock metal is, the manufacturing processes that use it, and sample applications.

Bar stock refers to a solid length of a raw metal material, such as carbon steel, alloy steel, stainless steel, aluminum, bronze, copper, or other metal. Individual pieces of bar stock are commonly made by extrusion or by melting the metal and pouring it into molds. The resulting pieces have a uniform profile (e.g., round, square, rectangular, or hexagonal), and come in a variety of lengths.
Bar stock may be used as-is for some applications; however, additional metalworking processes are often used to create finished parts, components, or assemblies. These include CNC machining processes like sawing, milling, drilling, or grinding, as well as extrusion, roll forming, and forging.
Bar stock material is used in many manufacturing processes because it can be procured in uniform shapes, lengths, and metal content. This translates to efficient and repeatable production since the stock material is consistent.
Additional benefits include:
Bar stock material is used in many industrial applications and operations. Steel bar stock can be machined into equipment parts, tools, structural members, and vehicle components. Aluminum can be extruded and formed with rollers to create long pieces with a consistent profile. Bar stock material can also be forged, as we&#;ll see below.
Forging is a metal forming process that can be used with a variety of metals, often beginning in bar stock form.
In forging, a piece of metal, often bar stock, is cut to size and then heated to a high temperature. The metal becomes very hot and pliable but remains solid. Depending on the application, it is then hammered, pressed between dies, or pushed into a mold to change its shape. Cold forging is another method in which metal is hammered or shaped without being heated.
Forging has many benefits, including:
Forging is a versatile process for creating parts and components in complex shapes and many sizes. Because it imparts added tensile and fatigue strength to metals, it is well-suited to heavy-duty applications in many industries. Common applications include:
