The Sino-Steel Tower (Chinese: 中钢大厦) is a 333 m (1,093 ft) tall skyscraper under construction in Tianjin, China. Construction started in 2008 and it is expected to be complete in 2014.
The building will contain offices and a hotel on 80 floors. The design by MAD Studio, Beijing, is for the building to be clad in white and pierced by recessed hexagonal windows. Some of the window surrounds will be crimson in colour, causing the building's appearance to alter with the changing light.
