At an incredible 828 metres (2,716.5 feet) and more than 160 storeys, Dubai’s Burj Khalifa is the world’s tallest building.
Engineers, designers, architects and skilled workers from more than 100 countries were involved in the making of the building. The construction took 22 million man-hours, where more than 12,000 dedicated personnel ensured the seamless progress of the building.
Burj Khalifa’s primary structure is made of reinforced concrete. The construction used 330,000 m3 of concrete and 55,000 tonnes of galvanized steel rebar. A cathodic protection system is in place under the concrete to neutralize the groundwater and prevent corrosion.
Due to the hot and humid outside conditions, an additional protective coating to the structure was required. Thus, the steel pipes used in the inner skeleton of the building were hot-dip galvanized along with the steel construction around the entrance to maximise protection.
The world’s tallest building is another testimony of the strength of Zinc. We all have Zinc in our lives.
Hindustan Zinc is India’s only and world’s leading Zinc-Lead-Silver Producer.
