Additionally, fiberglass is lightweight, which can reduce transportation and installation costs. In terms of structural strength, steel is generally more economical for high-load applications, but fiberglass’s unique properties—such as its electrical insulation and resistance to extreme weather—make it a better choice for specific industries. When evaluating costs, it’s important to consider the total lifecycle expenses rather than just the upfront price of materials.
