Sheet Metal is Cut on a Hydraulic Press.

What is sheet metal fabrication process?

Sheet metal is used in a variety of industries. In HVAC, for instance, ductwork is often fabricated from sheet metal. Sheet metal fabrication for HVAC uses the same process as any other industry. The process basically involves taking flat sheets of metal like steel or aluminum and shaping them into a variety of products like ducts by cutting, folding, punching, and assembling them. Tools ranging from band saws and chop saws to cutting torches and press brakes (which bend the metal) are used to shape the metal. The products are often assembled through various welding techniques. One of the unique services that Redding Heating & Air offers is sheet metal fabrication in Redding, CA. We can shape a variety of products for you. Find out how we can help by calling 530-223-1332.

What are the types of fabrication?

There are multiple types of sheet metal fabrication ranging from cutting and punching to stamping and casting. Cutting is one of the most common fabrication processes used in a variety of industries. Sheet metal typically comes in long rolls and in order for it to be used in manufacturing a product it must be cut into manageable sections. Machinery used for cutting include lasers and plasma torches. When it comes to fabricating sheet metal for HVAC, folding and bending processes are essential to develop products like ducts and other accessories.

What are the types of sheet metal?

Almost any kind of metal can be used in sheet metal fabrication. Typically, however, most sheet metal is commonly either steel, aluminum, or brass. Each of the metals is often of different grades and a variety of thicknesses, or gauges. The type of metal used will depend on what is being produced and how and where it will be used. Some metals, for instance, are chosen for their corrosion resistance, while others are chosen for strength.

What are the tools used in sheet metal work?

There are a variety of tools used in sheet metal fabrication. For cutting you might require sophisticated equipment like lasers or plasma torches, but you might also use a tool like an angle grinder cutting, grinding, or sharpening, or a throatless shear for straight, curved, or irregular cuts. Tools like a planishing hammer are used to flatten the metal or shape it into fine shapes, while flanges or punch tools are used to punch holes into the material. There are also tools used for shrinking and stretching the metal, depending on what’s needed at the time. Press brakes are commonly used to bend the metal. 

How do you do sheet metal fabrication techniques?

Several techniques are used in sheet metal fabrication. 

  • Assembling: Sections of sheet metal are put together by welding or binding them with adhesives, and bending with crimped seams.
  • Bending: Metal is bent either with hammers or press brakes.
  • Blanking: A part is cut from a larger piece of metal, and the large piece is discarded.
  • Cutting: Sheets of metal are cut or chiseled into manageable pieces using devices like manual power tools or machines like lasers. 
  • Die-cutting: This type of cutting doesn’t rely on forming chips or using melting or burning.
  • Fastening: For thinner metals, fasteners like nuts or studs are used to secure pieces together.
  • Finishing: The surface of a completed metal project is altered to improve aspects like appearance, corrosion or wear resistance, or conductivity.
  • Galvanizing: A protective zinc coating is applied over steel or iron as a part of rust prevention.
  • Punching: Holes or shapes are punched into the metal.
  • Welding: Various types of welds are used to secure pieces of metal together.

These are just a few techniques used to fabricate metals.

Sheet metal fabrication for insulation

In many industrial applications, piping and tubing need insulation jacketing to protect the pipes from wear or moisture or mechanical damage. Sheet metal is sometimes used to create that jacketing. When selecting a material for jacketing you must consider mechanical, chemical, and thermal and moisture aspects. Aluminum sheets are frequently used as jacketing because aluminum is lightweight and corrosion-resistant. Galvanized steel is often used in chemical plants as a barrier against corrosive fumes and chemical leaks.
