-
Cast iron, wrought iron and steel are alloys of iron and carbon
-
Cast iron could only be produced in limited quantities; it has good compressive strength but relatively poor tensile strength
-
Wrought iron was produced in small quantities by further processing of cast iron to develop improved tensile strength and ductility
-
Between 1770 and 1850, improvements in production made possible the increasing use of cast and wrought iron in construction
-
Greater technical knowledge and an expanding industrial society produced some of the most exciting buildings and structures that Britain has ever known.
-
There was also considerable public and professional resistance to the widespread use of such new materials.
-
Once production methods were established for steel it quickly replaced the use of iron
