Metals are valued for their unique properties such as strength, conductivity, and malleability in various industries. They play crucial roles in construction for building structures and roofing, as well as in manufacturing for producing machinery, tools, and appliances.

One common property of metals is their high tensile strength, which allows them to withstand large forces without breaking. This property makes metals suitable for structural applications in construction and for manufacturing durable products in various industries.

Metals are suitable for electrical wiring and heating systems due to their excellent conductivity. They allow electricity and heat to flow efficiently through wires and heating elements, making them essential components in electrical and heating systems.

A key characteristic of metals is their malleability, which allows them to be easily shaped and formed into different shapes and structures without losing their properties. This property enables intricate designs and manufacturing processes in various industries.

Metals are commonly used in construction for building structures and roofing. Steel, aluminium, and iron are among the most common metals used due to their strength, durability, and corrosion resistance, providing stability and longevity to buildings.
