Wrought iron
Steel
Rivets
Glass
Concrete

To understand the significance of these materials, it is essential to explore each component used in the Eiffel Tower’s construction.

Wrought Iron: Wrought iron serves as the primary material of the Eiffel Tower. It is a type of iron alloy that contains very low carbon (less than 0.08%). This property makes it malleable and ductile, allowing for intricate designs. Gustave Eiffel, the engineer behind the tower, utilized wrought iron to create a lightweight yet sturdy structure. Approximately 18,000 metallic parts and 2.5 million rivets were used in its assembly. A study by the French Institute for Advanced Mechanics highlights that wrought iron was crucial for both the aesthetic and structural integrity of the tower.
Steel: Steel, a stronger material than wrought iron, was increasingly used in construction during the late 19th century. Although the Eiffel Tower primarily used wrought iron, early versions of its components included steel reinforcements. Steel provided enhanced strength and durability. For example, the tower’s lower levels feature some elements that are made from early steel alloys, which improved resistance to stress under heavy winds.
Rivets: Rivets are metal fasteners that hold the various parts of the tower together. The use of rivets in construction is a significant technological advancement from older methods like using wooden pegs. The Eiffel Tower required about 2.5 million rivets, ensuring a solid connection between structural elements. Their strength contributes to the overall stability of the tower against strong winds, as noted by engineering studies conducted on the tower’s resilience.
Glass: Glass was used in the observation decks and the upper levels of the Eiffel Tower. It allowed for spectacular views of Paris while providing natural light inside. The presence of glass reflects the aesthetic considerations of design, combining functionality with beauty. A gallery constructed by the Conseil de Paris highlights how glass enhances the visitor experience.
Concrete: Although not a primary material, concrete was utilized in the foundation of the Eiffel Tower. It provides a solid base that supports the towering structure. The combination of concrete with iron elements creates a stable and enduring foundation, essential for towering structures. Historical accounts, including those from the engineer Gustave Eiffel, emphasize the importance of a well-engineered foundation to support the immense height of the tower.

These materials combined harmoniously to create an innovative landmark. The Eiffel Tower symbolizes a blend of engineering prowess and artistic vision.
