For over three decades, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has been leading innovation in the field of storage tanks. As Vietnam continues its rapid industrialization and infrastructure expansion, especially in sectors like oil & gas, water resources, and liquid chemicals, the demand for safe, reliable, and emissions-compliant liquid storage tanks is increasing dramatically. Floating Roofs, a critical element of safe liquid storage, play a key role in controlling evaporation losses, reducing VOC emissions, and improving environmental safety.As a trusted supplier of storage tanks, we serve a broad spectrum of industries—from petrochemicals and water treatment to food and pharmaceuticals—across more than 100 countries.In this context, Center Enamel’s Floating Roofs stand out as the premier solution—backed by robust engineering, durable materials, and performance in some of the world’s most challenging environments.
Floating Roofs are specialized roof systems installed inside or above liquid storage tanks that float directly on the surface of stored liquids, adapting their level with the fluid. Unlike fixed-roof tanks, which have a constant air space above the liquid, floating roofs minimize vapor space, reducing evaporation losses and mitigating fire and explosion risks.
lExternal Floating Roofs (EFRs) – Installed on open-top tanks
lInternal Floating Roofs (IFRs) – Installed beneath fixed roofs
Both types offer tremendous advantages for industries storing volatile, flammable, or temperature-sensitive liquids such as crude oil, gasoline, diesel, jet fuel, and various petrochemical products.
Minimize VOC emissions
Prevent product contamination
Enhance fire safety
Comply with API 650, EPA, and environmental regulations
Our modular floating roof systems are fully customizable based on tank diameter, liquid type, environmental exposure, and operational requirements.
Vietnam’s emergence as a Southeast Asian economic powerhouse has placed immense pressure on its energy, water, and chemical infrastructure. As investment in refineries, water treatment plants, chemical processing, and bulk liquid transport rises, so does the need for safe and sustainable storage.
Vietnam is home to key refining and chemical hubs,These facilities require vast networks of liquid storage tanks, often handling high volumes of crude oil, naphtha, kerosene, and aromatics. Without proper vapor containment, these tanks pose risks of economic loss, pollution, and occupational hazard.
Installing Center Enamel Floating Roofs significantly reduces evaporation loss and strengthens Vietnam’s compliance with:
National Technical Regulation on Emission (QCVN)
ASEAN harmonized standards
Global ESG and green energy mandates
Floating roofs are not exclusive to the oil and gas sector. In Vietnam’s rapidly urbanizing provinces, water utilities and industrial parks require storage tanks for:
Potable water
Process water
Industrial effluent
Our Floating Roofs are ideal for minimizing algae growth, maintaining water purity, and preventing odor—especially important in Vietnam’s tropical climate where heat and humidity promote rapid biological activity.
Floating roofs are essential for the storage of solvents, additives, edible oils, fermentation liquids, and acids. These liquids often require sealed, stable environments where oxidation, evaporation, or cross-contamination must be avoided.
Center Enamel offers customized solutions for Vietnam’s fast-growing chemical and food processing sectors, enabling safe, scalable, and hygienic storage.
As a globally trusted Floating Roofs manufacturer, Center Enamel brings a wealth of expertise and value-added engineering to every project. Whether your facility is in Hai Phong, Da Nang, or Ho Chi Minh City, our floating roofs are designed for long-term performance in tropical monsoon conditions and corrosive industrial environments.
We manufacture floating roofs using:
Marine-grade aluminum alloys (corrosion-resistant and lightweight)
Stainless steel (for chemical durability)
Composite polymers (for specialized chemical applications)
This ensures superior corrosion resistance, minimal maintenance, and long service life.
All Center Enamel floating roofs are constructed using prefabricated modular panels, allowing:
Fast installation
Easy transportation
Minimal site disruption
This is particularly beneficial for storage tank retrofits or remote facility upgrades across Vietnam’s provinces.
All Center Enamel floating roofs are engineered to comply with:
API 620, ISO, and ASME
EPA and QCVN requirements
Each system includes complete documentation—drawings, test reports, material certifications—ensuring full regulatory and project specification compliance.
Center Enamel Floating Roofs have already proven their effectiveness across diverse applications:
In Hai Phong and Binh Duong, our floating roofs reduce product loss and boost environmental safety in fuel storage operations.
In Quang Ngai, floating roofs are used in chemical complexes storing methanol, aromatics, and intermediates for plastics production.
In Ho Chi Minh City, our floating roof systems support large potable water tanks by controlling algae and contamination risks in exposed tanks.
In Vietnam’s thriving beverage industry, our IFRs offer reliable vapor control for fermentation liquids and flavor-sensitive oils.
Vietnam is making important strides in aligning with global climate targets and green industrial practices. industries must now embrace technologies that minimize environmental footprints.
Reduce greenhouse gas emissions
Prevent water and soil contamination
Extend the lifespan of storage infrastructure
Lower long-term maintenance and resource waste
Comply with ISO 14001 environmental management standards
Our floating roofs are a smart, proven solution for future-proofing Vietnam’s energy and liquid storage industries.
As Vietnam’s industries expand and mature, the infrastructure for storing and managing liquids must evolve to meet new demands for efficiency, safety, and sustainability.
Center Enamel is proud to offer world-class Floating Roofs that deliver:
Exceptional vapor control
Compliance with Vietnamese and international standards
Custom-engineered solutions for oil, chemical, water, and food sectors
End-to-end project support and service excellence
With proven installations across Southeast Asia and deep experience in tropical environments, we are the Floating Roofs manufacturer that Vietnamese industries can trust for their most critical storage projects.
Let’s build Vietnam’s sustainable storage future—floating roof by floating roof.
