Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) provides precision-engineered aluminum floating roofs that combine structural lightweighting with maximum chemical compatibility, ensuring long-term operational safety for refineries and tank farms worldwide.
The Full-Contact Aluminum Floating Roof is designed to float in direct contact with the stored liquid. By utilizing a high-buoyancy, modular honeycomb or panelized structure, the roof physically displaces the air-vapor interface. This "zero-gap" approach effectively suppresses the evaporation of volatile organic compounds (VOCs), protecting both the environment and the economic value of the stored asset.
Our FCAFR systems are designed and fabricated in strict accordance with:
● API 650 Annex H: The primary global standard for internal floating roofs, governing structural design, buoyancy requirements, and testing.
● NFPA 11: Compliance for foam fire-protection systems within the rim space.
● API 2000: Standards for venting and pressure relief to ensure tank integrity during filling and emptying.
● Material Grades: Use of high-strength 6061-T6 or 5000-series aluminum alloys for superior corrosion resistance and structural rigidity.
Choosing a Full-Contact Aluminum Floating Roof over a traditional pontoon-style roof provides several critical operational benefits:
By eliminating the vapor zone (ullage) beneath the roof, the FCAFR reduces evaporative losses by up to 99%. This is the most efficient way to meet 2026 global emission mandates.
With no vapor space available for ignition, the risk of internal tank explosions or fires is virtually eliminated. This design is the safest choice for storing high-volatility products like gasoline and jet fuel.
Aluminum’s natural oxide layer provides exceptional resistance to the corrosive vapors of crude oil and refined products. Center Enamel’s roofs require near-zero maintenance over a 30+ year service life.
The full-contact modular design ensures that buoyancy is distributed evenly across the entire surface area. This prevents localized sinking and allows the roof to support the weight of maintenance personnel or heavy snow loads.
Our Full-Contact Aluminum Floating Roofs are the preferred choice across diverse high-stakes containment sectors:
● Refineries & Bulk Fuel Terminals: For the storage of gasoline, diesel, jet fuel, and crude oil.
● Chemical Processing Plants: Handling aromatic hydrocarbons and volatile chemical feedstocks.
● Strategic Petroleum Reserves: Managing large-diameter tanks where even minor evaporation represents significant financial loss.
● Aviation Fueling Hubs: Ensuring product purity and moisture control for high-grade jet fuels.
