The Twin Towers are a striking glass-and-steel combination with floor plans based on an eight-pointed star. The Towers were designed to symbolize strength and grace using geometric principles typified in Islamic architecture. The towers are also joined at the 41st and 42nd floors (175m above street level) by a 192ft-long (58.4m) double-decker skybridge - linking the two sky lobbies and facilitating the movement between
the two towers.

The 'composite' structure of the Towers employs both the flexibility of steel and the rigidity of high-strength concrete. Each component material was used to best effect in constructing the 452 m-high buildings. About 80,000 cubic metres of high strength concrete with 37,000 tons of steel were used to form the frames of both Towers. Complementing the stainless steel is 55,000 square metre of 20.38 mm laminated glass designed to minimise heat gain by reflecting harmful UV light and unwanted solar radiation.

Supported by 23-by-23-metre concrete cores and an outer ring of widely-spaced super columns, the towers use a sophisticated structural system that accommodates its slender profile and provides from 1300 to 2000 square metres of column-free office space per floor.

Interior
In the entrance halls' foyer, inspired by traditional Malaysian motifs from handicraft and weaving, stainless steel fittings and screens float in the spacious voids overhead.

The wall panels and screens are inspired by the traditional 'songket', a hand-woven traditional Malay fabric with gold and silver threads and worn mainly during official functions and ceremonies, as well as hardwood carvings from villages along the East Coast of Peninsular Malaysia.



The Skybridge
The Skybridge symbolises a gateway to the future and is used to facilitate movement between the two towers. It is supported by a "three-hinged arch" consisting of giant round bearings at the base and a pair of legs 51 metres in length. The base of the arch is located at level 29 of each tower. The cylindrical legs are bolted to a box girder below the centre of the double-decked bridge.

Pinnacles
The PETRONAS Twin Towers' pinnacles, made of structural steel, stand 73.5m tall. The pinnacles play an important part in both the aesthetics and functionality of the Towers. The timeless minaret design is a crowning symbol of the country and its culture. Each pinnacle is composed of a spire, mast ball and ring ball, which are in turn made up of 50 unique elements, interlocked into single 176-ton pieces.

The PETRONAS Twin Towers, was built by Petronas, Malaysia's national oil company and developed as an integral part of the Kuala Lumpur City Centre (KLCC) project.
