Features & Advantages
High durability and strong structural integrity：Produced from perforated metal plates that are formed and welded into shape, ensuring excellent strength and resistance to bending or distortion.
Adjustable filtration rating and hole configuration：A variety of aperture sizes, hole shapes (round, square, slotted, etc.) and open area percentages can be tailored to meet specific filtration requirements.
Superior corrosion and heat resistance：Available in stainless steel, carbon steel, galvanized steel, titanium and other alloys for use in demanding or corrosive environments.
Excellent flow capacity with reduced pressure loss：Consistent perforations allow smooth fluid passage, lower flow resistance and help prevent blockage during continuous operation.
Long service life, washable and economical to maintain：The filter body can be reused multiple times and easily cleaned through backflushing, brushing, ultrasonic or chemical cleaning methods.
Diverse fabrication options and connection styles：Can be produced with flanges, threaded ends, caps or welded joints to suit various installation requirements.
Functions as both filter medium and protective support layer：Can work as a primary filter element or as reinforcement for fine mesh materials such as woven wire cloth or sintered media.
Versatile use across many industrial fields：Widely applied in oil and gas processing, chemical plants, water treatment systems, food production, pharmaceuticals, mechanical filtration equipment and more.
Applications
Oil & gas filtration：Suitable for crude oil filtration, drilling fluid filtering, oilfield equipment protection.
Pharmaceutical and medical industry：Used as support layers for multi-layer precision filter cartridges.
Chemical and petrochemical processing：Resistant to acid/alkali corrosion, ideal for harsh chemical environments.
Water and wastewater treatment：Removes suspended particles and protects downstream components.
Food and beverage filtration：Stainless steel structure ensures hygiene and safety.
Plastic and polymer melt filtration：Efficiently removes gels and unmelted particles.
Airflow control and mufflers：Ensure even airflow, minimize turbulence and noise, and enhance overall sound absorption performance.
Machinery equipment protection：Filters lubricants/coolants and prevents clogging of pumps, valves, nozzles.
Strainers, basket filters, candle filters：Used in strainers, basket filters, and candle filters as a strong support layer to hold filter media, maintain shape, and enable smooth flow for primary particle separation.
