Metals are solid material that are generally hard, shiny, malleable, fusible, ductile, and have goodelectrical and thermal conductivity. Metals are commonly used in the construction industry due to their durability and strength to formstructuralcomponents, pipework, claddingmaterials and other components.
Steel is an alloy of iron and a number of other elements, mainly carbon, that has a high tensile strength and relatively low cost and is used for structural and other applications in the construction industry.
Types of steel include:.
Stainless steel: Steel combined with chromium (and sometimes nickel). Stainless steels generally do not formrust on their surfaces and do not discolour. Galvanised steel: A zinc coated steel that is resistant to corrosion.
Weathering steel: Has a rust-like appearance that can resist corrosion and abrasion, by forming a protective surface layer, or patina. For more information see: Steel. Because of its ductility, aluminium can be formed into many shapes and profiles. Aluminiumwallcladding systems are commonly used for buildingexteriors, with large wallpanels requiring fewer joints, resulting in time-efficient installation.
Today, aluminium is the second most used metal in buildings after steel, used for roofing, flashing, wallpanels, windows and doors, spandrels, and so on.

Types of iron include:.

It is also used as a claddingmaterial, sometimes allowed to oxidise to a blue greencolour.

Lead is a heavy metal that can be toxic when absorbed into the body. In construction, lead is used due to its ductility to formroofs and other claddingpanels as well as windows, linings for cornices, tanks, copings, gutters and downpipes, flashing, and so on.
It is also a component of soft solder.
Historically it was used in paints and pipework. Most lead-based paint was banned from sale to the general public in the UK in 1992. It has not been used for waterpipes since 1970, however, it may still be present in older properties.
It is recommended that leadpipes should be replaced.
Other metals that might be used in construction include:. The term 'metal' can also be used to refer to:. Constructing or repairing a highway with roadmetal (a metalled road). For more information see: Metalled.
