manufacturing
Companies and organizations involved in producing supplies and assembled goods.
A manufacturing firm or organization is a producer of mass-produced man-made or machine-made products in factories and assembly plants.
The role concerns production of goods in factories or assembly plants. A producer can make a finished product or supplies used in later work.
Construction applies physical work to a structure, while manufacturing produces goods. Supplying a project with manufactured components and installing those components are distinct activities.
