Subgirts are usually fabricated from which range of gauge metal sheets?

Explanation:
Subgirts are light structural members formed from relatively thin metal, chosen to balance stiffness, weight, and ease of fabrication. The best range is 16–22 gauge because it provides enough rigidity to resist bowing and give solid attachment points for fasteners and finishes, while still being easy to cut, form, and install and not adding unnecessary weight or cost. Gauges lighter than that (like 24–28) tend to be too flimsy for spans and connections, while gauges heavier (such as 12–18 or 8–12) add unnecessary weight and expense for typical subgirt applications.
