Due to the coronavirus pandemic, World Expo, like other world events, has been postponed. The event will now take place from 1 October 2021 to 31 March 2022 in Dubai, UAE. Called Expo 2020 Dubai, it will be the first World Expo ever hosted in the Middle East, Africa, and South Asia (MEASA) region. Expo 2020 Dubai is expected to attract 25 million visitors, and 190 nations have already confirmed their participation including Luxembourg with a 2100 m2 pavilion built with ArcelorMittal Europe – Long Products’ steel.

Steel from Belval and Differdange

ArcelorMittal was selected to supply the steel products for the construction of the building’s structure. The 170 tonnes of hot rolled structural steel shapes from the IPE and HE European size series were made in the Luxembourg mills of Belval and Differdange - in electric arc furnaces fed with recycled scrap as raw material. This is today’s most energy and resource preserving production route. As a natural key advantage of steel, the structural components were designed with mechanically fastened connections. At no extra cost, this solution allows for the economical disassembling, transportation, and reassembling of the pavilion for its next-use life.

A breathtaking design inspired by its nation

The pavilion is inspired by its nation: small and ambitious, intriguing and reassuring, and above all generous and open. The overall theme is ‘Opportunity,’ reflecting the country’s history, its present, and its future. The overall shape of the pavilion resembles a Möbius loop, where the twisting of a ribbon yields one single surface with no beginning and no end expressing infinity and, in particular, symbolising the circular economy. The face of the ribbon transiently serves as floor, wall, and ceiling thereby allowing a multifaceted scenography from the starting point to the top floor.

The visitors’ experience begins in the entrance area. As a kind of red carpet, a wide ramp between the inside and the outside skin of the building invites you on a journey of discovery via a gently sloped path to the next floor. It enthrals the visitors as they merge with the pavilion’s exhibition, which in a natural an interactive way displays a series of visuals featuring the country and its people.

The ground floor mainly accommodates the gift shop, restaurant, and the visitor’s ramp to the first floor. The first level hosts a multi-functional area for receptions and conferences, as well as the ramp guiding visitors without interruption towards the top. The second floor, the highest point, is dedicated to an exhibition of Luxembourg’s space economy.

To reach the earth again, a visitor has three options: taking the stairs or the lift are the conventional options, but a slide winding through the picturesque green patio is the fun one.
