Observation Deck: Made of Glass and Steel
The observation deck of the CN Tower is an iconic and breathtaking attraction in Toronto, Canada. It offers visitors panoramic views of the city and beyond, attracting millions of tourists each year. The construction of the observation deck involved the use of glass and steel, which are the primary materials that make up this magnificent structure.
The glass used in the observation deck is a special type called laminated glass. Laminated glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two layers of glass. This process creates a strong and transparent material that is resistant to breakage. The use of laminated glass ensures the safety of visitors, as it prevents shattering in case of any accidents or extreme weather conditions.
In addition to the laminated glass, the observation deck also features a steel framework. The steel structure provides the necessary support and stability for the deck, allowing it to withstand the weight of the visitors and the forces of nature. The steel beams and columns are meticulously designed and engineered to distribute the load evenly and ensure the structural integrity of the deck.
The combination of glass and steel creates a stunning and modern aesthetic for the observation deck. The transparency of the glass allows visitors to enjoy unobstructed views, while the steel adds a touch of boldness and strength to the overall design. This combination perfectly captures the essence of the CN Tower – a symbol of technological innovation and architectural excellence.
