Steel cone roofs are heavy, require internal vertical columns that disrupt fluid mixing, and must be continuously sandblasted and repainted due to rust from internal vapor condensation. Aluminum domes are self-supporting (no columns), 1/3 the weight of steel, and natively form a passive oxide layer that completely prevents atmospheric rust, meaning they never need to be painted.
Yes. Because aluminum is exceptionally lightweight, the horizontal thrust of the dome is absorbed entirely by its own peripheral tension ring. This means it adds minimal dead load to the existing structure and can be safely retrofitted onto older bolted, welded, or concrete tanks without requiring extensive structural sidewall reinforcement.
With over 30 years of manufacturing excellence and nearly 200 proprietary patents, Center Enamel is Asia's preeminent manufacturer of integrated liquid and gas storage solutions. From advanced 3D Finite Element Analysis (FEA) to comprehensive EPC execution, we ensure your bulk storage assets are engineered for maximum durability, absolute safety, and decades of leak-free performance.
