Título: Acero en la Expo Mundial de Shanghai
Título original: Steel at the Shanghai World Expo
Resumen: Steel plays a prominent role at the 2010 Shanghai World Expo. Many countries use steel as a design feature in the construction of their pavilions.

The façade and roof of the Swedish pavilion is made of a special energy-saving steel that dissipates the heat of the sun and keeps the interior cool. The Australian pavilion is made of a weathering steel, which gives the building a distinctive ochre colour, evocative of the Australian outback.

The Swedish high strength steel producer SSAB was responsible for the perforated plates that cover the Swedish pavilion. Organic coating mixtures and pigments in the yellow and white paint reflect sunlight and reduce energy consumption in the building by up to 15%. The theme of the Expo is ‘Better City, Better Life’, and SSAB’s high-tech steel “contributes to reduced impact on the environment”, said Martin Pei of SSAB. According to the company, the “qualities of the material can be compared with leaves on trees which act as a heat transfer medium in times of strong solar radiation”.

SSAB held technical seminars and interactive demonstrations on high strength steel at the pavilion in mid-May.

Australia’s BlueScope Steel produced the self-sealing and durable weathering steel that covers the Australian pavilion. Over time, the colour of the building will deepen giving the façade a changing patina over the six months of the Expo.

The architects of the building chose the material for its “unique durability, texture, patina and its ability to evoke the Australian landscape”. The cassette-style weathering steel panels are formed using fully automatic folding machinery. The automated process allows precise alignment between the steel panels (to 0.3mm).

One of the most striking pavilions at the Expo is the Danish pavilion, a double-looped structure that contains a cycle park and a swimming pool overlooked by the Little Mermaid statue from Copenhagen. The pavilion is made of white-painted steel plates manufactured at a Chinese shipyard.

Other notable steel designs can be seen at the Japanese Industry pavilion which features reuse of steel pipes from an old factory, and the Taiwanese pavilion - a transparent cube made of steel and glass housing a suspended reflective globe.

The Shanghai World Expo opened on 1 May and will close on 31 October.
