英国采购需求：中国聚碳酸酯温室和温室

I'm seeking a quote for a 25-acre polycarbonate greenhouse equipped with all necessary certifications. The structure should feature double hot galvanised steel and robust polycarbonate sheets, along with essential cooling, heating, lighting, and irrigation systems. Hydroponics systems, benches, PVC gutter boxes, ground covers, and fertilizer systems are also required. Please ensure it's suitable for the coastal conditions of Algarve, Portugal, considering strong ocean winds. For the greenhouse structure, please use quality materials, ensuring durability and reliability. Specific steel dimensions and designs are needed for columns, trusses, beams, and guttering. I'd appreciate your expertise on materials and any additional recommendations for coastal implementation. Looking forward to your prompt response.
