With over 30 years of experience in industrial storage solutions, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has earned its position as a global leader in storage tanks.Today, Center Enamel continues to deliver cutting-edge solutions tailored to the needs of critical sectors like the petrochemical industry, particularly with our high-performance Internal Floating Roofs (IFRs). These specially engineered structures are essential for reducing evaporative losses, minimizing emissions, and ensuring environmental compliance in volatile liquid storage—challenges that are increasingly relevant to the emerging energy infrastructure of Timor-Leste.
From Glass-Fused-to-Steel tanks to epoxy-coated steel tanks, stainless steel process tanks, and advanced aluminum domes, our innovations serve a broad range of industries across more than 100 countries.As a trusted Internal Floating Roofs manufacturer, Center Enamel provides robust, corrosion-resistant, and customizable floating roof systems that support operational safety and environmental sustainability throughout the oil, gas, and chemical sectors.
Internal Floating Roofs (IFRs) are secondary containment structures installed inside above-ground storage tanks. Unlike fixed or external roofs, internal floating roofs float directly on the surface of stored liquids, effectively minimizing the vapor space between the liquid and the roof. This drastically reduces the amount of product lost through evaporation and limits the emission of volatile organic compounds (VOCs) into the atmosphere.
Floating design to eliminate vapor build-up
Vapor recovery compatible
Corrosion-resistant aluminum or stainless steel construction
Custom seal systems for high tightness and chemical resistance
Lightweight modular design for easy installation and transport
Available in full-contact and non-contact deck formats, our IFRs are engineered based on tank size, product characteristics, and environmental requirements.
As Timor-Leste accelerates its development in the oil and gas sector—particularly with the expansion of the Tasi Mane petroleum corridor and investments in refining and downstream processing facilities—ensuring sustainable and safe hydrocarbon storage is a growing national priority.
Timor-Leste's petrochemical infrastructure must meet international benchmarks for efficiency and accountability. Evaporation loss from open or fixed-roof tanks represents a significant financial drain, especially when storing volatile liquids like crude oil, gasoline, and petrochemical derivatives.
Center Enamel's Internal Floating Roofs are designed to:
Minimize product loss
Maintain vapor pressure balance
Maximize usable storage volume This contributes directly to operational profitability while aligning with emerging energy management strategies.
VOCs released from unsealed storage tanks contribute to ground-level ozone, smog, and health hazards. For a country committed to sustainable development and climate change mitigation, installing vapor-control technologies like IFRs is crucial.
Center Enamel’s IFRs help Timor-Leste’s petrochemical facilities comply with global environmental standards such as:
US EPA regulations
EU Clean Air Guidelines
The presence of flammable vapors in petroleum storage poses a significant explosion and fire risk. Internal Floating Roofs create a barrier between the stored liquid and ignition sources, dramatically improving fire safety.
By reducing oxygen-vapor contact and limiting tank venting, IFRs serve as a passive fire prevention system, especially important in Timor-Leste's hot and humid climate.
As Timor-Leste invests in expanding its energy infrastructure, Center Enamel’s Internal Floating Roofs are poised to deliver value in diverse petrochemical applications:
Center Enamel IFRs are ideal for centralized oil storage facilities being developed as part of the Tasi Mane project. Their ability to reduce loss and ensure safe long-term storage is critical for operational and export-ready stockpiles.
In urban hubs like Dili and Suai, bulk storage of refined petroleum products must meet safety and environmental codes. Our IFRs prevent leakage, reduce emissions, and safeguard product quality in high-volume tank farms.
As Timor-Leste explores refining operations to reduce dependency on fuel imports, floating roof systems will play a vital role in safely managing by-products like naphtha, aromatics, and light ends.
As a proven Internal Floating Roofs manufacturer, Center Enamel combines materials science, structural engineering, and global project experience to deliver products that consistently exceed expectations.
We use top-grade aluminum alloys and stainless steels to manufacture IFRs that are:
Immune to corrosion
Non-sparking
Weather-resistant
Compatible with aggressive liquids
Our systems are designed for decades of service with minimal maintenance, helping reduce total cost of ownership.
Center Enamel's IFRs feature multi-layered primary and secondary seals, engineered from elastomers like PTFE and nitrile to resist swelling, heat, and chemical attack.
This ensures vapor-tight integrity, regardless of temperature fluctuation, tank diameter, or stored material volatility.
All our internal floating roofs are prefabricated in modular panels, facilitating:
Quick field installation
Low shipping costs
On-site adaptability
Whether for a new tank build or a retrofit project, Center Enamel can deliver a solution optimized for your site’s layout, tank dimensions, and product type.
All our floating roofs are designed according to guidelines, with complete documentation including:
Engineering drawings
Load calculations
Material certificates
Welding specifications
This ensures seamless integration with EPC contractors and global compliance.
With over 100 countries served—including Indonesia, Vietnam, UAE, and Nigeria—Center Enamel brings unmatched international insight. We understand:
Local climate conditions
Regulatory expectations
Logistic limitations
Cultural and linguistic contexts
Our experience helps us deliver smoothly on projects in developing industrial markets like Timor-Leste.
As Timor-Leste strengthens its petrochemical capacity, it must balance economic aspirations with environmental responsibility. Infrastructure choices made today will define the country’s sustainability profile for decades.
Center Enamel’s Internal Floating Roofs support this balance by:
Preventing unnecessary resource loss
Protecting air quality
Reducing maintenance demand
Aligning with ESG and climate goals
Our solutions reflect the global shift toward cleaner energy operations, making them not only practical but future-ready.
