Using metal in construction

Advantages

  • Copper is a good electrical conductor for wiring; it is not reactive so can be made into water pipes
  • Lead can be bent easily so is used to seal joints on roofs
  • Steel is strong for girders and scaffolding
  • Aluminium alloys are corrosion resistant

Disadvantages

  • Iron and steel can rust, severely weakening the structure
  • The exploitation of metal ores to extract metal causes pollution and uses up the Earth's limited resources
  • Metals are more expensive than other materials such as concrete

Evaluation

Steel is a commonly used metal and is often used in the construction industry. In terms of strength, it is unbeatable. It does have drawbacks, as mentioned in the disadvantages column.
