What properties does expanded metal typically have?

Solid and unyielding
Open mesh pattern
Flexible and pliable
Heavy and dense

The correct answer is: Open mesh pattern

Expanded metal is characterized by its unique open mesh pattern, which is created through a process of slitting and stretching flat sheets of metal. This results in a type of material that has a series of interconnected openings, allowing for airflow, drainage, and light passage, making it versatile for various applications such as walkways, security screens, and architectural features. The open mesh structure not only provides strength and durability but also reduces weight compared to solid metal sheets, making it easier to handle and install. This property is crucial in industries where both strength and weight considerations are important, enhancing the material's usability in different contexts.
