"The Eiffel Tower is made of puddled iron. This type of iron is obtained by mixing liquid hot iron and the result is iron of a fibrous texture obtained through the dissociation of carbon and impurities from the cristallographic structure. Hammering and rolling complete the preparation of this highly resistant iron.
On the building site, 120 workmen and highly experienced supervising staff finished assembling the various parts using rivets that were driven in with a hammer, by hand. The assembly works were done using rivets driven hot as soon as their final location had been secured. As they cooled, the rivets would contract and it would guarantee tightening of the parts to one another.
It is interesting to point out that only one third of the 2,500,000 rivets were fitted on the spot and that all the others were set in Levallois-Peret where the assembly works were carried out.The rivets were supplied by a company located in Paris called Letroyeur et Bouvard.
Four men were required to fit a rivet, one who would heat it, one to hold it in and one to shape its head (on either side of the beam) and the last one who would flatten it with a hammer."
