semifabricate

Semifabricate is a term used to describe the process of producing a product or component in a semifinished state, meaning it has undergone some manufacturing or forming but still requires additional processing to reach final specification. As an adjective, semifabricated describes such intermediate components or products.

In manufacturing and construction, semifabricates serve to shorten lead times, standardize interfaces, and enable on-site finishing. They occupy a middle ground between raw materials and fully finished goods. Common semifabricated forms include billets or slabs of metal, preformed panels, stamped subassemblies, machined blocks, and other components that have undergone initial forming, cutting, or joining but still require further processing, heat treatment, coating, or final assembly.

Applications span several industries. In construction, semifabricated wall panels, roof trusses, or bridge girders are manufactured off-site and installed with on-site finishing. In automotive and aerospace, semifabricated subassemblies such as door frames or fuselage sections accelerate assembly lines and reduce on-site fabrication work.

Notes: the term is not standardized; some contexts use semi-finished, semi-fabricated, or prefabricated more often. Clear definition should be provided in contracts or procurement specifications to avoid ambiguity. Related terms include semi-finished goods, prefabrication, and off-site manufacturing.
