Use of wrought iron in construction has a long history (cramps made from wrought iron were used in classical antiquity). [6] The first all-wrought iron roof was apparently installed in 1837 at the Euston railway station in London. [7] Frame of the Crystal Palace. Beams and girders were made of wrought iron with I-beam cross-section. The ...
Iron columns had been used in Wren's designs for the House of Commons and were used in several early 18th-century churches in London, but these supported only galleries. In the second half of the 18th century the decreasing costs of iron production allowed the construction of major pieces of iron engineering.
The 22m Iron Pagoda at the Yuquan Temple (Jade Springs Temple), Dangyang, Hubei, was built during the Song dynasty in 1061, and is the most outstanding example to survive. Cast iron pagodas were then superseded by even more elaborate bronze ones, but cast iron continued to be used for decorative items such as bowls and statues.

Cost – The cost of these construction materials will depend entirely on the geographical location of the project and the availability of the materials. Just as the price of gasoline fluctuates, so do the prices of cement, aggregate, steel, etc. Reinforced concrete derives about half of its construction costs from the required form-work.
The shares from the construction industry alone were 6% and 11% respectively. Energy consumption during building material production is a dominant contributor to the construction industry's overall share, predominantly due to the use of electricity during production.
Cast iron is a brittle form of iron which is weaker in tension than in compression. It has a relatively low melting point, good fluidity, castability, excellent machinability and wear resistance. Though almost entirely replaced by steel in building structures, cast irons have become an engineering material with a wide range of applications ...
The average pay for a reinforcing bar ironworker in residential construction was an hourly wage of $23.59 in early 2009, and rebar ironworkers in commercial and industrial construction earned an hourly wage of $39.11. [12] The typical tools of a reinforcing bar ironworker are pliers, tie wire reels, rodbuster bags, and rebar hooks.
