International Design Standards and Compliance
Center Enamel understands that global projects require strict adherence to internationally recognized standards. Our Aluminum Geodesic Dome Roofs are designed and constructed in compliance with:
AWWA D108 – Aluminum Dome Roofs for Water Storage Facilities
API 650 – Welded Tanks for Oil Storage
ADM 2015 – Aluminum Design Manual
ASCE 7-10 – Minimum Design Loads for Buildings and Other Structures
IBC 2012 – International Building Code
By following these industry-leading standards, we ensure that our dome roofs meet structural, safety, and performance requirements for municipal, industrial, and commercial storage applications worldwide.
Why Aluminum? The Material Advantage
Aluminum offers inherent advantages over traditional roofing materials such as carbon steel or concrete. Its unique combination of strength, light weight, and corrosion resistance makes it ideal for long-term storage infrastructure.
1. Exceptional Corrosion Resistance
Aluminum naturally forms a protective oxide layer that shields the material from corrosion. Unlike steel, which requires protective coatings and regular repainting, aluminum maintains its structural properties without additional surface treatment.
This characteristic makes aluminum dome roofs particularly suitable for:
Municipal drinking water tanks
Industrial wastewater tanks
Coastal and marine environments
High-humidity regions
Agricultural storage facilities
The elimination of painting and recoating significantly reduces maintenance costs over the life of the structure.
2. Lightweight Yet Structurally Strong
Aluminum’s high strength-to-weight ratio allows for expansive clear-span roof designs without the need for internal support columns. This lightweight property reduces:
Structural load on tank sidewalls
Foundation requirements
Transportation costs
Installation time
At the same time, the engineered geodesic structure distributes loads evenly across the dome surface, ensuring excellent resistance to wind and snow loads.
3. Long-Term Economic Value
When evaluating total cost of ownership, aluminum dome roofs consistently outperform traditional alternatives. Although initial material costs may be comparable, lifecycle savings from minimal maintenance, corrosion resistance, and extended service life provide substantial long-term financial benefits.
Structural Design: Batten Bar System
One of the defining features of Center Enamel’s Aluminum Geodesic Dome Roofs is our advanced Batten Bar Structural Design.
This system optimizes beam strength and ensures watertight performance through:
Precision-engineered aluminum beams
High-performance silicone gasket sealing systems
UV-resistant and temperature-resistant components
Secure mechanical fastening technology
The silicone gasket system maintains elasticity even under prolonged exposure to ultraviolet radiation and extreme temperatures, ensuring long-term leak-free operation.
The batten bar configuration enhances structural stability while simplifying assembly, making installation efficient and reliable.
Advanced Node (Hub) Design
The node connection is a critical structural element in geodesic dome performance. Center Enamel utilizes a proprietary extruded aluminum node design, combined with a spun aluminum gusset cover to provide:
Precise load transfer
Enhanced rigidity
Corrosion-resistant connection points
Leak-proof sealing
This advanced hub system improves structural integrity while maintaining ease of installation. The result is a durable, stable, and aesthetically refined dome structure capable of withstanding demanding operational conditions.
Clear-Span Capability: Maximizing Tank Efficiency
One of the primary advantages of aluminum geodesic dome roofs is their ability to provide large clear-span coverage. Without internal support columns, tank operators gain:
Maximum storage capacity
Unrestricted internal access
Improved operational efficiency
Enhanced mixing and processing performance
Compared with steel or concrete roof systems, aluminum’s lightweight properties allow for greater span distances while maintaining structural integrity.
Flexible Installation Methods
Center Enamel provides two primary construction methods tailored to project requirements and tank configurations:
Inside-Out Construction
In this method:
Internal beams and panels are assembled at the tank center
The structure is lifted using a temporary steel pole system
Remaining components are progressively installed outward
The dome is completed from the center to the perimeter
This approach is particularly suitable for large-diameter tanks.
Outside-In Construction
For tanks built using jacking systems:
External beams and panels are assembled directly on the tank sidewall
Components are installed inward
The dome structure is completed toward the center
Both installation methods are designed for rapid assembly, safety, and efficiency. Our proprietary lifting and hoist systems ensure precise placement and secure installation.
