Puddled iron, a kind of wrought iron, was used to build the Eiffel Tower. The Eiffel Tower's puddled iron (worked iron) weighs 7,300 tonnes, while the overall structure, including non-metal components, weighs around 10,000 tonnes. The metal is an alloy of 70% iron and 30% carbon.
The Eiffel Tower is cast iron on the inside surface of its steel framework. This was done to avoid any contact between the tower and its tenants. The original idea came from Gustave Eiffel himself. He wanted to create a building that could be easily dismantled and transported to another location if needed.
Iron has been used for skyscrapers since the 1880s but it wasn't until the 1890s that it began to replace steel as the material of choice. The reason for this is that iron is heavier than steel, which allows builders to use smaller support beams, which in turn saves on construction costs.
The Eiffel Tower is still standing today after being open to the public for over 100 years. It is now owned by the City of Paris and operated by a private company called SETE (Société d'Études et de Tourisme du Val-de-Seine).
In conclusion, the Eiffel Tower is a monument made of iron and steel that sits atop a base of concrete and stone.
The Eiffel Tower is a massive wrought-iron lattice construction that weighs 7,300 tons and has 2.5 million rivets. It includes three viewing decks that are linked by several stairways and elevators. The tower is named after its creator, Gustave Eiffel.
The tower was built as a replacement for an earlier iron structure that was destroyed by arson. Construction on the new tower began in 1887 and it was opened to the public the following year. The tower cost about $3 million at the time it was built; today it would be worth far more than this amount.
When it was first constructed, the Eiffel Tower was the highest building in Paris, but this title now goes to the Chrysler Building which is only one floor higher. In any case, the Eiffel Tower remains a popular attraction in France and around the world.
In 1987, a small group of protesters managed to get inside the tower with banners and candles. They were able to remain inside for nearly two hours before they were discovered by security guards. No harm came to them but this incident caused tension between the protesters and the police. The protesters said that they were there to protest French nuclear testing while the authorities claimed that they were just having a picnic without permission.
The iron used to construct the Eiffel Tower was refined using a process known as "puddling," which removes excess carbon when the ore is melted. Following this technique, practically pure iron is obtained, which, according to Gustave Eiffel at the time, was the best and most sturdy of materials. The tower is made of wrought iron.
The Eiffel Tower is made up of two parts: the pedestal and the iron structure attached to it. The pedestal, which stands on four legs, is about thirty-five feet high and weighs nearly twenty thousand pounds. It is made of stone from the Champagne region (north of France) and was built by the French architect Charles-Eugène Levier. The iron structure, which extends out about forty-five feet from the pedestal, is also held up by four legs. It consists of three tiers, each composed of eight segments connected by steel rods. The upper part, which is covered with copper plates, is designed like an inverted pyramid with its apex at the top of the pedestal. This makes the entire structure resemble a giant metal flower in the shape of a tripod. The height of the Eiffel Tower has been compared to that of other famous structures such as the Chrysler Building in New York City and the Petronas Twin Towers in Kuala Lumpur, Malaysia. However, the Eiffel Tower is actually taller because it has more floors.
