The largest dome with a continuous roof measures 210.107 m (689 ft 3 in) in diameter and was achieved in Jeddah, Kingdom of Saudi Arabia on 30 May 2021.
HaoTan supplied the high zinc coating galvanized steel pipe for the whole dome. Our high zinc coating galvanized steel pipe stands out with a series of remarkable advantages. The high zinc coating significantly enhances corrosion resistance. Zinc, known for its self - sacrificial properties, forms a protective layer that effectively shields the steel substrate from environmental factors such as moisture, oxygen, and various corrosive substances.
Our steel pipe exhibits excellent strength and durability. It can withstand substantial structural loads, making it an ideal choice for the demanding requirements of a dome structure.
