The final steel beam was installed on Shanghai's tallest building on Sunday, with the skyscraper reaching is designed height of 632 meters.

The 137-story Shanghai Tower in Lujiazui financial and trade zone in the city's Pudong New Area is expected to open in the middle of next year.

Gu Jianping, president of Shanghai Tower Construction and Development Co., Ltd., said the company will now mainly focus on interior and exterior decoration.

The landmark building will include offices, commercial space, a five-star hotel, exhibition and conference halls and recreational facilities.

The tower will help meet demand for high-end offices as the city seeks to become an international financial center and free trade zone, according to Gu.
