Is the creation of metal structures by cutting, bending and assembling processes. It is a value-added process involving the creation of machines, parts, and structures from various raw materials.
Typically, a shop builds the product. Large fab shops like Gemmell's employ a multitude of value-added processes, including welding, cutting, forming and machining.
As with other manufacturing processes, both human labor and automation are commonly used. A fabricated product may be called a fabrication, and shops specializing in this type of work are called fab shops. The end products of other common types of metalworking, such as machining, metal stamping, forging, and casting, may be similar in shape and function, but those processes are not classified as fabrication.
Forming converts flat sheet metal into parts by applying force without adding or removing material. The force must be great enough to change the metal's initial shape. Forming can be controlled with tools such as punches and dies. Our machinery can regulate force magnitude and direction. Our machine-based forming tools can combine forming and welding to produce lengths of fabricated sheeting (e.g. linear grating for water drainage).
With Gemmell's experience, proper design and use of tools with machinery creates a repeatable form that we can use to create products for many industries, including aerospace, automotive, construction, civil and architectural.
