Wrought iron

Wrought Iron (or soft iron) is an iron material that has the property of being forged and hammered when very hot ("red-hot") and hardens by cooling rapidly. It melts at temperatures above 1500 °C, is not very tough and can be welded by forging.

Uses

Industrial processes in the 19th century made it possible to produce wrought iron in large quantities, so that this material could be used in the construction of large architectural and engineering structures.

The difficulty of joining wrought iron elements by welding has relegated the use of this material to decorative or secondary uses in construction, such as gratings and other pieces.
