Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has grown into a globally trusted name in industrial storage tank solutions, including Glass-Fused-to-Steel tanks, Fusion Bonded Epoxy tanks, Stainless Steel bolted tanks, and Galvanized Steel tanks. At the forefront of our innovation is the Center Enamel Aluminum Dome Roof—a lightweight, corrosion-resistant, and structurally robust solution ideal for covering dry bulk storage tanks. Designed and engineered to withstand tropical climates, typhoon winds, and coastal corrosion, our aluminum domes are now gaining prominence in the Philippines, where industries from cement and grain storage to fertilizers and chemical powders are seeking long-term, maintenance-free tank covers.Over three decades of manufacturing excellence have empowered Center Enamel to become a premier solution provider across sectors such as chemical processing, biogas engineering, drinking water storage, wastewater treatment, and now—dry bulk storage.
Aluminum domes are self-supporting, geodesic structures made from high-grade aluminum alloy components. They are used as tank covers for both liquid and dry bulk storage tanks, offering unmatched strength-to-weight ratio, corrosion resistance, and architectural elegance. In contrast to steel or concrete roofing, aluminum domes do not require internal support columns, making them ideal for applications where material flow, headspace optimization, and contamination control are critical.
Key characteristics of Center Enamel aluminum domes:
Design: Triangulated geodesic structure using extruded aluminum struts
Joining System: Bolted node and hub connection with radial and circumferential stiffening
Installation: Constructed at grade level and lifted into position or assembled in situ
Customization: Designed to meet tank diameter, environmental load, and access requirements
Our domes are especially effective when paired with dry bulk storage tanks where the internal environment must remain free of external contaminants such as rain, dust, bird droppings, and sunlight.
The Philippines’ dry bulk storage industry is expanding due to the country’s growing agricultural sector, increased demand for cement in infrastructure, and its strategic location as a trading and logistics hub in Southeast Asia. Industries storing grains, cement, fertilizers, fly ash, salt, sugar, plastic pellets, and other powders require airtight, corrosion-resistant, and lightweight storage solutions. This is where aluminum domes offer a distinct competitive advantage.
Given the archipelagic geography of the Philippines, many storage facilities are situated in humid, saline, coastal zones. Aluminum domes provide natural corrosion resistance that far exceeds that of painted steel or galvanized iron. The inherent oxide film on aluminum prevents surface degradation even under salt-laden air, monsoons, and typhoon rains.
Despite being significantly lighter than steel, aluminum domes can span tank diameters without internal supports. This not only reduces the overall structural load on the tank shell and foundation but also simplifies transportation, assembly, and maintenance—critical for islands and remote regions of the Philippines.
Aluminum domes eliminate the need for central columns or trusses, maximizing the internal volume and ensuring free-flowing material discharge. For silos and dry bulk tanks using mechanical conveyors or pneumatic loading systems, this unobstructed space enables smoother operations and faster throughput.
With no coatings or paints to reapply, aluminum domes require minimal upkeep over decades. This lowers the total cost of ownership and reduces the risk of operational disruptions due to maintenance activities.
The Philippines presents a wide spectrum of industries that benefit from dry bulk storage tanks with aluminum dome covers:
Rice, corn, soybean, and wheat storage benefit from aluminum domes that keep stored grains dry, pest-free, and aerated. With increasing focus on post-harvest loss reduction, dome-covered silos are replacing traditional open piles and tarpaulin solutions.
Construction firms and cement producers use aluminum domes to protect cement, fly ash, and lime from moisture ingress. Exposure to rainwater can initiate hydration, reducing quality. Domes also prevent dust emissions, complying with air quality standards.
Moisture-sensitive fertilizers like urea or ammonium nitrate require airtight and dry storage conditions. Aluminum domes offer robust sealing and ventilation systems to maintain product integrity.
As a full-service Aluminum Domes manufacturer, Center Enamel offers more than just product supply—we deliver end-to-end engineered solutions backed by experience, innovation, and trust.
All dome components and manufacturing processes are carried out under stringent quality systems, certified to ISO 9001, ISO 14001, OHSMS, and more. We ensure our products comply with:
AWWA D108 standards
API 650 roof specifications
ASCE wind and seismic load criteria
WRAS and FDA material approvals where applicable
This makes our domes suitable for international tender projects, government contracts, and EPC-led infrastructure developments.
Each dome is custom-engineered using CAD modeling to optimize for:
Site-specific wind, snow, and seismic loads
Required access points, walkways, hatches, and vents
Compatibility with existing steel or concrete tank shells
Modular and bolt-together construction for quick on-site installation
We also provide complete technical documentation including fabrication drawings, structural load calculations, and installation guides.
From feasibility analysis to site supervision, Center Enamel offers turnkey support including:
Material sourcing and prefabrication
Logistics coordination and export packaging
On-site assembly or lift-and-place dome erection
Maintenance training and after-sales service
Our experienced engineering team collaborates closely with Filipino contractors, architects, and consultants to ensure project timelines and performance goals are met.
As the Philippines continues to invest in infrastructure, food security, and energy resilience, the demand for modern, durable, and climate-adapted storage infrastructure is accelerating. Aluminum domes provide the performance edge that today’s industries need to operate efficiently, cleanly, and sustainably.
Whether it's protecting valuable dry goods, ensuring uninterrupted operations during typhoon seasons, or meeting global safety and environmental regulations, Center Enamel’s aluminum domes are setting new benchmarks in the field.
Backed by 30+ years of tank manufacturing experience, globally certified quality, and a commitment to customer success, Center Enamel is proud to support the Philippines' industrial growth with high-quality, cost-effective aluminum dome solutions tailored to local needs.
