What is expanded metal commonly used for in construction?

1. For roofing materials

2. For reinforcement and decorative purposes

3. For forming the base of electric circuits

4. For insulation attributes

The correct answer is: For reinforcement and decorative purposes

Expanded metal is widely recognized for its versatility in both structural and aesthetic applications within construction. The unique pattern created during the manufacturing process not only provides strength and durability, but it also allows for various uses, particularly in reinforcement and decorative purposes. In reinforcement, expanded metal can be used as a backing for plaster and drywall, as well as in concrete applications to enhance structural integrity. The open lattice structure permits Bonding with other materials, which adds to its strength. Additionally, its decorative qualities make it appealing for architectural features, such as screens, facades, and ornamental grilles. The ability to manipulate the finish and design of expanded metal allows architects and builders to create visually interesting elements while maintaining functionality. While expanded metal does have applications in roofing, electrical circuits, and insulation, these uses are secondary compared to its primary strengths in providing both reinforcement and decorative elements.
