From the history of metals. Metals

From the history of metals. Metals began to be widely used as construction materials not so long ago. Before the beginning of the nineteenth century metals played little structural role in the process of building. Mostly they served for joining parts of buildings. The ancient Greeks and Romans are known to use bronze for joining slabs of stone.It was only in the eighteenth century when the first all-metal structure was built in Europe. It was a cast-iron bridge across the river Severn in England. The strength of the bridge turned out to be so great that now, more than two centuries after its construction, it still carries heavy modern traffic across the Severn.In the first half of the nineteenth century cast iron and wrought iron were introduced and used for industrial construction in Europe and North America. Steel was not widely used, being considered a rare and expensive building material. Inexpensive steel first began to be produced and used only with the invention of the Bessemer process, in the 1850s. From that period on, metal started to be used as rather popular and useful building material. The famous Eiffel Tower of Paris was constructed of wrought iron in 1889.By that period several steel frame skyscrapers had already been built in the United States. That was the beginning of the new era; a new highly useful and popular construction material had been born and introduced into building industry

From the history of metals. Metals began to be widely used as construction materials not long ago. Before the beginning of the ninth century of metal planned little structural role in the process of building. They have to take part in the construction part. The ancient Greeks and Romans are known to use bronze for joining slabs of stone.
This is the only time in the eighteenth century when all the first metal structures were built in Europe. This is a cast iron bridge across the River Severn in England. The strength of the bridge turned out to be so great that now，more than two centries after its construction，it still carries heavy modern traffic across the Severn.
In the first half of the nineteenth century cast iron and wrught iron were introduced and used for industrial construction in Europe and North America. Being considered a rare and expendable building material Inexpensive steel first began to be produced and used only with the invention of the Bessemer process，in the 1850s.From that period on，metal started to be used as rather popular and useful building material. The famous Eiffel Tower of Paris was constructed of wrught iron in 1889.By that period several steel frame skyscrapers had already been built in the United States. This is the beginning of a new era; a new material with high utilization and population structure is born and introduced into building industry
