Which term describes individual and distinct pieces used in construction, such as electrical and plumbing products?

The term that best describes individual and distinct pieces used in construction, such as electrical and plumbing products, is "Discrete Product." This term refers to items that are separate and distinguishable, meaning they can be individually identified and function independently within a system. Each discrete product serves its own purpose, whether it's a plumbing pipe, electrical fixture, or HVAC component, allowing for modularity and flexibility in construction.

The other options are less appropriate in this context. "Component Products" generally refers to parts that come together to form a whole, but it may not emphasize the individuality as "Discrete Product" does. "Integrated Systems" implies that various components work together as a unified system, which is not focused on the individual aspects. "Continuous Materials" refers to items that are not made up of separate parts but rather exist in a continuous form, like concrete or steel beams, which do not align with the idea of distinct, separate products.
