What matierials enabled the ESB to be built taller than existing skyscrapers?

The Empire State Building (ESB) was built taller than existing skyscrapers primarily due to the use of steel and reinforced concrete, which provided the necessary structural strength and stability. The innovative design incorporated a lightweight frame that reduced the overall weight while allowing for greater height. Additionally, the use of modern construction techniques and materials, such as the aluminum and glass facade, contributed to its iconic height and aesthetic appeal.
