Aluminium Geodesic Dome Roof
Aluminium (more specifically an aluminium alloy) is one of the world’s most common- ly used metals. Its lightness coupled with its strength, and excellent corrosion resistance are the main reasons for it being used in the design of the aluminium geodesic dome roof and this non corrosive property means that the aluminium geodesic dome roof can be used on tanks used to store most products.
The aluminium geodesic dome roof is a system of triangular, lightweight extruded profiles, normally from the 6000 series, that act in compressive and tensile force to resist loading. The profiles are connected through node points and this configuration works together transmitting loads laterally to the integral tension ring and then through sliding or fıxed supports to the tank shell and tank foundation. The framework is then covered with a minimum; usually from the 3000 or 5000 series, H16 Tempered 1.2 mm thick aluminium sheeting. Because of the corrosion resistance of aluminium alloys the aluminium geodesic dome roof does not require painting – EVER, and can there- fore be considered as maintenance free in this respect for the entire lifetime of the tank.
Maxell Geodesic Dome Roof is an all bolted structure and no welding is required at site for its assembly and erection, it fully complies with the requirements of API 650 Appendix G.
We normally offer the following features in our stand- ard design:
- Gauge Hatch Assembly
- Access/ManwayAssembly
- CentreFreeVentAssembly
- SkylightAssembly
- Free vented design with Sliding Supports
- BirdScreen
Maxwell Aluminium Geodesic Dome Roof can be assembled inside the tank and lifted into its final posi- tion with either a system of pulley blocks or a crane. If using the “jacking method” to erect the tank, the Maxwell Aluminium Geodesic Dome Roof is fitted on the top course and jacked up with the shell.
Essentially any equipment that you have on a conven- tional steel dome or cone roof tank can be fitted on the Maxwell Aluminium Geodesic Dome Roof and without any significant modification to the equipment or the roof.
Maxwell Aluminium Geodesic Dome Roof is normally designed with a maximum radius equal to 1.2 times the tank diameter and the minimum is 0.7 times the tank diameter, this equates to the ratio of dome height to tank diameter of about 1:6.
