Aluminium Internal Floating Roofs by Center Enamel
Advanced Evaporation Control and Safety Solutions for Modern Storage Tanks
In today’s global industrial landscape, storage tank systems must meet increasingly stringent requirements for safety, environmental protection, operational efficiency, and long-term durability. One of the most effective technologies addressing these demands is the Aluminium Internal Floating Roof (IFR).
At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we design and supply high-performance Aluminium Internal Floating Roofs that integrate seamlessly with welded steel tanks, bolted steel tanks, and glass-fused-to-steel (GFS) tanks, delivering superior evaporation control, reduced emissions, and enhanced storage safety for a wide range of applications.
With nearly two decades of experience in storage tank systems and accessories, Center Enamel has established itself as a trusted global provider of complete containment and cover solutions, serving clients in more than 100 countries worldwide.
Understanding Aluminium Internal Floating Roofs
An Aluminium Internal Floating Roof is a lightweight, corrosion-resistant floating deck installed inside a fixed-roof storage tank. The roof floats directly on the liquid surface and moves vertically as the liquid level changes, eliminating the vapor space between the stored liquid and the fixed roof.
By minimizing vapor formation, aluminium internal floating roofs significantly reduce:
Evaporation losses
Volatile Organic Compound (VOC) emissions
Fire and explosion risks
Product contamination
Unlike external floating roofs, internal floating roofs are fully protected from environmental exposure such as wind, rain, dust, and ultraviolet radiation, making them particularly suitable for harsh climates and sensitive storage applications.
Why Aluminium Is the Preferred Material for Internal Floating Roofs
Aluminium has become the industry’s preferred material for internal floating roof systems due to its exceptional combination of physical and chemical properties.
1. Outstanding Corrosion Resistance
Aluminium naturally forms a protective oxide layer that resists corrosion without the need for coatings or repainting. This makes aluminium internal floating roofs especially suitable for long-term service in storage tanks containing water, wastewater, industrial liquids, and petroleum-related products.
2. Lightweight and High Strength
Aluminium’s high strength-to-weight ratio allows for large-span floating roofs with minimal structural load on the tank shell and foundation. This lightweight design improves buoyancy, enhances safety, and simplifies installation.
3. Long Service Life with Minimal Maintenance
Because aluminium does not rust and requires no surface treatment, aluminium internal floating roofs deliver decades of reliable performance with minimal maintenance, significantly reducing lifecycle costs.
Center Enamel’s Expertise in Aluminium Roof Systems
As a leading storage tank manufacturer and containment system provider, Center Enamel brings unmatched expertise to aluminium roof engineering. Our capabilities extend beyond internal floating roofs to include aluminium geodesic dome roofs, fixed tank roofs, and integrated tank-cover solutions.
Our aluminium roof systems are designed using advanced 3D computer modeling, ensuring precise engineering, optimal load distribution, and consistent manufacturing quality.
Design Standards and Engineering Compliance
Center Enamel’s aluminium internal floating roofs are engineered in compliance with internationally recognized standards, ensuring safety, reliability, and regulatory acceptance across global markets. Design considerations align with:
API standards for storage tanks and floating roof systems
AWWA standards for water storage applications
ISO quality management systems
OSHA safety guidelines
Relevant structural and environmental regulations
Each roof is customized based on tank diameter, stored liquid properties, operating temperature, and site conditions.
Structural Design Features
Optimized Floating Deck Design
Center Enamel aluminium internal floating roofs feature precision-engineered floating decks designed to provide excellent buoyancy, stability, and load distribution. The deck structure ensures smooth vertical movement with changing liquid levels while maintaining continuous contact with the liquid surface.
Advanced Sealing Systems
High-quality sealing systems are integrated into the roof perimeter to minimize vapor leakage and enhance emission control. These seals accommodate tank shell irregularities while maintaining long-term elasticity and durability.
Reliable Support and Guide Mechanisms
Guide poles and support components ensure stable roof movement and prevent tilting or binding during operation. All components are engineered for corrosion resistance and long-term reliability.
Integration with Center Enamel Storage Tank Systems
One of Center Enamel’s key advantages is the ability to deliver fully integrated storage solutions. Aluminium internal floating roofs can be supplied as part of a complete system, including:
Glass-Fused-to-Steel (GFS) tanks
Welded steel tanks
Bolted steel tanks
Aluminium geodesic dome roofs
This integrated approach ensures perfect compatibility, simplified project coordination, and reduced installation risk.
Environmental and Economic Benefits
Reduced Evaporation Losses
By eliminating vapor space, aluminium internal floating roofs significantly reduce product loss due to evaporation. This directly translates into cost savings, particularly for large-volume storage tanks.
Lower Emissions and Environmental Impact
Reduced VOC emissions help operators comply with increasingly strict environmental regulations and support sustainability initiatives.
Improved Product Quality
Minimizing exposure to air reduces oxidation and contamination, preserving the quality of stored liquids, especially in water, food-related, and industrial applications.
