Common Questions About Sheet Metal Fabrication Answered

What is sheet metal?

What is sheet metal?

This is metal that has been formed into sheets with the thickness ranging from .180 inches (7 gauge) to .018 inches (26 gauge). Sheet stock thicker than .180 is called plate.Sheet metal is formed by rolling, hammering or extruding metal to give it a flat, even surface. There are several metals such as stainless steel, carbon steel, aluminum, tin, brass, or copper that are commonly made in sheet form. Precious metals such as silver and gold can also be formed into sheets. Sheet metal fabrication is a process entailing cutting, bending and assembling of the metal to create the desired product.

How is the thickness of sheet metal measured?

A gauge is the unit of measurement that is used for determining the thickness of ferrous sheet metal. Typically, such sheet metal could measure anywhere between 26 gauge to 7 gauge. The smaller the gauge number, thicker is the metal. For non-ferrous metals such as copper, aluminum, gold or silver, the measurement unit is Ounce. Different applications call for the use of sheet metal in varying thickness. Another important aspect is the grade of the metal that is determined on the basis of attributes such as purity, corrosion resistance, malleability,etc.

Where is sheet metal used?

Sheet metal fabrication can be carried out for industrial, architectural, decorative or creative purposes. Look around, and you shall notice that the chassis and body panels of automobiles and airplanes are made of sheet metal. It is also extensively used in the construction sector, store fixtures industry, and medical industry. A number of decorative railings and tables are a result of metal fabrication. Another very unique use of this material can be seen in installation art pieces and sculptures.Stainless steel fabrication is common for such applications. Sheet metal can be perforated to create vents in ducts and tubes, or to manufacture decorative panels and screens.

How is sheet metal fabricated?

There are numerous ways to fabricate sheet metal. The fabrication process of metals begins with drafting and design. The actual fabrication process comprises shearing, saw and laser cutting, punching, forming operations, welding, assembly etc. Various machining operations such as drilling, tapping, counter-boring, turning etc can also be carried out on sheet metal depending on the product to be manufactured. Whether it is stainless steel fabrication or any other metal fabrication, these techniques are common to all types of metals.

Who can fabricate sheet metal?

There are firms that are engaged in the fabrication of metals such as stainless steel, mild steel, and aluminum among others. Such firms employ skilled workforce comprising fabricators and welders. They can be contacted for different requirements such as precision metal fabrication, architectural fabrication, manufacturing screw conveyors, fabrication of food processing machinery, perforated metal panels, and even contract manufacturing. It is imperative to choose a sheet metal fabricationfirm that has a proven track record of delivering quality work ontime.
