Ningbo GDoor hermetic doors adopt unique engineered rail track with special rubber which is attached with the downside of the door leaf. During the opening process, the door will slightly run upwards, then return to the normal track. And in the same way, when the door is closing, the door leaf will move along the normal track, then slightly run downwards to implement the hermetic effect. Compared with other Ningbo GDoor Automatic Sliding Doors, carriage sets of Ningbo GDoor medical hermetic doors are a little different from their running carriage sets.

After several erroneous starts and a long delay, the world's tallest building was finally given a start date to begin construction. The building will cost 1.2 billion U.S. dollars to build, and when it's completed, it will be the tallest building in the world and 550 feet higher than the Burj Dubai. The developer plan includes luxury hotels, apartments and apartments, as well as the world's highest observatory. The project was designed by the construction company Adrian Smith Gordon Gill.
When it is completed, the Kingdom Tower will eventually extend 3280 feet over Saudi Arabia, but so far it has not even begun to land in the desert. In 2012, the staff sank 330 feet of deep pit in the sand, but not much else happened after that. At present, the project has given the start date of April 27, 2014 and things have finally moved forward.
