What term describes factories that produce bulky or heavy goods?

Heavy industrial factories refer specifically to facilities that are engaged in the production of bulky or heavy goods. These factories typically deal with materials that require much more physical space, infrastructure, and resources due to the nature of the products they create, such as machinery, vehicles, or building materials. The processes involved in these factories often include significant logistics and handling aspects because of the considerable volume and weight of the goods involved.

In contrast, light industrial factories generally focus on lighter goods that require less complex manufacturing processes, while manufacturing plants can encompass a broad range of production types and may not be limited to heavy goods. Service industries, on the other hand, focus on intangible products and services rather than goods. Thus, the term heavy industrial factories is specifically accurate for describing facilities dedicated to the production of substantial, weighty items.
