JSF OIL&WATER S.A.
About
JSF OIL&WATER S.A., operating through its ALUROOFS brand, is a Spanish manufacturer with over 25 years of experience designing and producing self-supporting aluminium structural covers for storage tanks and industrial facilities. The company operates from offices in Pozuelo de Alarcón, Madrid and a manufacturing facility in Villadangos del Paramo, León, employing automated CNC design and laser-cutting precision manufacturing alongside a dedicated in-house engineering team. ALUROOFS offers four registered product lines: ALUSPHERE® geodesic dome covers engineered for large-diameter circular tanks, ALUCONE® conical covers providing sloped drainage and gas containment, ALUPLAN® flat covers for low-profile applications, and ALUGRECA® flat covers with corrugated profiles for added structural stiffness. All covers are designed to meet EUROCODE, AWWA, and API 650 standards and are manufactured using fully automated CNC processes. The aluminium construction provides inherent corrosion and UV resistance with no maintenance requirement. Applications include potable water reservoirs, wastewater treatment tanks, oil storage facilities, and industrial process vessels where covers prevent contamination, contain emissions, and control odors. ALUROOFS supplies detailed assembly instructions with each unit and offers specialized installation crews plus optional on-site supervisors for international projects. The company holds UNE-EN ISO 9001 and EN 1090-1 CE marking certifications.
