Fabrication is the process of constructing products by combining typically standard parts using one or more individual processes. Fabrication is used in many manufacturing industries, but it is particularly suited to industrial production in steel. Fabricators tend to be companies or factories that carry out the fabrication process, rather than individuals. There are many different types of fabrication, including mechanical and welded fabrication, as well as a wide range of other relevant disciplines such as machining and electrical/electronic assembly.
Manufacturers often turn to fabricators because they need access to specialist materials and equipment which they may not have available in-house, whilst designers may turn to fabricators because they are lacking expertise in a particular field and need help from experts who can bring skills to their design that otherwise might not exist within their company structure.
