Internal Floating Roof Solutions by Center Enamel
Enhancing Storage Tank Safety, Efficiency, and Environmental Performance
As global industries continue to demand safer, more efficient, and environmentally responsible storage solutions, Internal Floating Roofs (IFRs) have become an essential component in modern storage tank design. At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we provide high-performance Internal Floating Roof systems engineered to integrate seamlessly with a wide range of storage tanks, including welded steel tanks, bolted steel tanks, and glass-fused-to-steel (GFS) tanks.
Backed by nearly two decades of industry expertise, advanced manufacturing capabilities, and compliance with international standards, Center Enamel’s internal floating roof solutions are trusted worldwide for applications involving water, wastewater, petroleum products, chemicals, industrial liquids, and other stored media.
What Is an Internal Floating Roof?
An Internal Floating Roof is a floating deck installed inside a fixed-roof storage tank. It rests directly on the surface of the stored liquid and rises or falls with the liquid level. By eliminating the vapor space between the liquid surface and the fixed roof, an internal floating roof significantly reduces evaporation losses, minimizes emissions, and enhances storage safety.
Unlike external floating roofs, IFRs are fully protected by the tank’s fixed roof, making them ideal for regions with harsh weather conditions, high wind loads, or strict environmental regulations.
The Role of Internal Floating Roofs in Modern Storage Systems
Internal floating roofs play a critical role in:
Reducing product evaporation losses
Lowering volatile organic compound (VOC) emissions
Improving fire and explosion safety
Maintaining product quality
Enhancing regulatory compliance
For industries such as oil & gas, chemical processing, water treatment, food processing, and municipal infrastructure, IFRs are no longer optional—they are a strategic investment in operational excellence and environmental stewardship.

Key Advantages of Center Enamel Internal Floating Roofs
1. Superior Evaporation Loss Control
Internal floating roofs effectively eliminate the vapor space above stored liquids, significantly reducing evaporation losses. This is particularly important for tanks storing volatile liquids, industrial process water, treated water, and sensitive chemical solutions.
By reducing evaporation, operators benefit from:
Lower product loss
Improved cost efficiency
Enhanced environmental performance
2. Enhanced Safety Performance
By minimizing vapor accumulation inside the tank, internal floating roofs reduce the risk of fire, explosion, and corrosion. This added safety layer is especially valuable in industrial, municipal, and energy-sector storage facilities.
3. Compatibility with Multiple Tank Types
Center Enamel’s internal floating roofs are designed to integrate seamlessly with:
Glass-Fused-to-Steel tanks
Welded steel tanks
Bolted steel tanks
Concrete tanks with steel liners
This versatility allows engineers and EPC contractors to standardize roof solutions across diverse projects and applications.
4. Long-Term Durability and Low Maintenance
Manufactured using corrosion-resistant materials and precision-engineered components, Center Enamel IFRs are designed for long service life with minimal maintenance. When paired with GFS tanks or aluminum dome roofs, the entire storage system achieves exceptional durability and lifecycle economy.
