Self-supporting
The light weight of the material and the advantaged framing system enable Geodesic roof to be self supported on the tank wall and no in-tank column is needed, even with large tank diameter till 100 meter.
Safe structure to adapt different conditions
The roof’s well calculated and examined structure make it able to meet many challenge from the environment. The geodesic geometry can hold the high snow load, high wind load and the seismic zone. With the sealing system, the roof can achieve air-tightness under the atmosphere pressure, so to have great odor control performance.
Low Maintenance cost
Geodesic Roof uses high quality Aluminum alloy, the material has a naturally corrosion resistance in the atmosphere. So during the tank’s life service time (more than 30 years), no maintenance will be needed, the roof will keep it’s beautiful appearance. In high corrosive environments, the roof can have further surface treatment such as Anodic Oxidation.
Easy and fast construction
The dome roof is designed to work with YHR bolted tank, the effective frame and sealing system allow rapid construction, the jacks used for tank wall installation will also be able to used for the roof, no second investment will be needed. The workers can safely stay on the ground for the installation, and no experience are requested.
The aluminum dome is designed as a self-supporting, clear-span and fully triangulated structure and only its outer edge is connected to the tank shell around the outer rim. The Aluminum domes are generally constructed according API 650 appendix G, the standard setting details for aluminum domes on storage tanks in refineries. They are also ideal for bulk storage, potable water, waste water and architectural structures.
