Soaring at a height of almost half a kilometre into the atmosphere, the Petronas Twin Towers were built on the former Selangor Race Track in the heart of Kuala Lumpur.
With a total built-up area of 395,000 sq.m, the 88-storey twin towers are joint by a two-level sky bridge. Situated at a height of 58.4m, the skybridge was engineered to withstand strong typhoon winds and bad weather conditions. As of now, the Petronas Twin Towers are still the tallest twin buildings in the world. Tower One houses Petronas, Malaysia’s major petroleum producer while Tower Two consists of mixed tenancies.
Designed by César Pelli, the skyscrapers were inspired by traditional Islamic patterns. Each tower’s floor plate is created based on two interlocking squares, creating the shape of an eight-pointed star. These geometry shapes represent Islamic principles of unity, harmony, stability and rationality.
With a proven track record of over 150 years, Lysaght is dedicated to offering valuable roofing and structural decking solutions. Paired with the highest quality of processed steel building products in the world, our solutions are proven to withstand the effects of time.
Constructing the higher floors of the towers was one of the difficulties faced by the contractors. Thanks to almost 4,000 tonnes of LYSAGHT® BONDEK® II structural decking system, each level completion was reduced from 12 to four days. This system was integral in saving time and cost of building the Petronas Twin Towers.
The designers had a vision of building Malaysia’s testament of modernity and economic strength by constructing Kuala Lumpur’s first skyscraper. Unlike traditional designs on landmarks, the twin towers were focused on modern aesthetics using steel and glass materials on the building exterior to bring the postmodern look to life.
