Filter screens come in a wide variety of materials, typically selected based on the operating environment, filtration precision, and required durability. Stainless steel-such as grades 304 and 316-is the most common material; it offers excellent corrosion resistance, high-temperature tolerance, and strength, making it suitable for applications demanding high hygiene and durability standards, such as industrial water treatment, chemical processing, and food manufacturing.
Carbon steel filter screens offer high strength at a lower cost but have relatively poor corrosion resistance; they generally require galvanizing or coating treatments and are commonly used for general industrial filtration or in environments where corrosion resistance is not a critical requirement.
Additionally, there are filter screens made from plastics and synthetic materials, such as polypropylene (PP) and nylon. These are lightweight and offer good resistance to acids and alkalis, making them suitable for light industry, laboratory filtration, or residential water purification systems. Specialized applications may also utilize copper mesh, titanium mesh, or composite material screens to meet requirements for high precision or unique operating conditions.
