Detail description:

Steel Structure Design

Steel structure design should satisfy the state load code.

After model is set up, strength and rigidity analysis would be done, to ensure the deflection, force and stability would satisfy the requirement under the worst condition.

The design software of Jewers is developed according to the hangar door working principle, various loads, and the various codes of each country. It takes the cladding and dynamic loads into consideration, could give the force, deflection of each node and check the design according to the code of each country.



The outer surface could be spray painted steel sheet, color steel sheet, stainless steel sheet, aluminum composite board.

Currently the daylighting material could be Fiberglass-Reinforced Plastics, PC (polycarbonate) compact sheet, PC multi-wall sheet, and glass.


Bottom Tracks and Bottom Wheels


Bottom tracks will be light rail or heavy rail, depend on the detail design. The height is flush with the ground level. There are trace heating and drainage designs. Kerb angles will be installed along the sides of the tracks. The track centre is 400-800 mm. There are composite rubber packers under the track.
