Aluminum Dome Roof

Dome roof of WORLD BRIDGE INDUSTRIAL CO.,LTD works as the roof which completely prevent rainwater from going into and minimize the evaporation of product contained in the tank.
Thorough FEM structural design analysis shall be necessary to withstand the load such as, wind, snow and seismic factor without support of extra column.

In addition, the section design of strut has been developed and applied for the light and strong Aluminum dome roof, this strut section design is recognized as the world best by the worldwide patent from Korea, U.S, Germany, Japan, China, Turkey and Australia

Design Features

• Flat full flow strut design
• Water and air tightness sealing
• Compatible with all petroleum product
• Easy to installation of all accessories accuracy and tightened structural design
.

Main Benefit

• All corrosion-free Aluminum
• Most effective leak free solution
• Emissions『eduction
• Low total cost of the roof solution
• No welding at the site
• Liaht weiaht and maintenance free

Atmosperlc Storage Tank

Thorough FEM structural design analysis shall be necessary to withstand the load such as, wind, snow and seismic factor without support of extra column.

The main strut section design has been developed and applied for light and strong aluminum dome roof, WB’s new technology, Flat batten type strut has been recognized as the world best by great reputation from world customers and worldwide patent from U.S, Germany, Japan, China and Australia.

Pressurized Storage Tank

Most advanced Aluminum dome roof design of World bridge industrial makes it possible that internal pressure is set up in the tank by max. 250mmWC (API650 appendix G).

– Embedded sealing design by Flat batten strut design
– Special rubber fastening design
– Special batten gasket material
– Improved design of shoe structure specialized for pressurized tank
– Advanced membrane application

Structural Analysis

To analyze geodesic aluminum dome roof structure, wb carefully review material properties,
boundary conditions and other factors by finite element method
