Impressions of BAU Munich

It is 5 metres high. Its leaves are made from steel and weigh 500 kilograms each. It is hard to capture on a smartphone camera but opens easily, without the slightest effort. Despite its unique size, the VISS facade pivot door is impressively light. It was the centre of attraction throughout the whole week of the trade fair and symbolised our open, intensive and inspirational relationship with our customers.

A better world thanks to steel

How does steel make the world a better place? worldsteel’s latest video tells you all you need to know about one of the world’s most versatile materials in under three minutes. It brings to life in a clear and compelling way key facts about steel and the ways in which it touches every aspect of our lives.

In 2012, the steel industry generated revenue of more than 800 billion dollars. Approximately 8 million people worldwide work in steel production that is still frequently associated with dirt, smoke, sparks, and fire. The video reinforces how the methods of producing steel are getting more environmentally-friendly, and how steel can be recycled with no loss of quality for reuse in production. Once manufactured, steel endures throughout the entire life cycle, making it one of the most resource-efficient materials of all.

“We are […] committed to achieving a vision in which steel is recognised as a key element of a sustainable world – and hope our new video is a good way of communicating that vison and message.” (Edwin Basson, Director General, worldsteel)


worldsteel: The World Steel Association (worldsteel) is one of the largest industry associations in the world and represents approximately 170 steel producers, national and regional steel industry associations, and steel research institutes. worldsteel members represent around 85% of world steel production.
