- The Sydney Opera House is made of over 1 million tiles of pre-cast concrete, prefabricated in Sweden and shipped to Australia.
- The concrete tiles are made of a special aggregate that includes crushed granite and sand, and are reinforced with steel rods.
- The concrete was chosen for its durability, low maintenance, and ability to withstand the harsh Australian climate.
Glass
- The Sydney Opera House also features large areas of glass, which were used to create the building's iconic sail-like structure.
- The glass is made of a special tempered glass that is extremely strong and resistant to breakage.
- The glass was also treated with a special coating to reduce glare and heat gain.
Steel
- Steel was also used extensively in the construction of the Sydney Opera House, primarily for the building's structural framework.
- The steel used is a high-strength alloy that is resistant to corrosion and weathering.
- The steel was also treated with a special coating to protect it from the harsh Australian climate.
Granite
- Granite was used for the paving of the Sydney Opera House's forecourt and other areas of the site.
- The granite is a hard, durable stone that is resistant to wear and tear.
- The granite was also chosen for its aesthetic appeal and its ability to complement the other materials used in the construction of the Sydney Opera House.
