Description
Product Introduction
Precision perforated filter and sieve screens in stainless steel, engineered for accurate particle separation, liquid filtration and as rigid support media behind finer wire mesh.
Product Introduction
Perforated metal filter screens are engineered for the specific job of separation and filtration, where aperture accuracy matters more than appearance. Zhongman produces fine-perforated screens primarily in stainless steel 304 and corrosion-resistant 316L, with apertures from 0.5 mm up to 5 mm punched to tight tolerance. These screens act as standalone sieves for particle grading, as filter elements for liquids and gases, and very often as the rigid support layer that holds delicate fine wire mesh flat against pressure. Unlike woven mesh, a perforated screen offers a self-supporting, dimensionally stable surface that can be rolled into cylinders, pressed into baskets or fabricated into filter cartridges without distorting its open area.
Key Features & Advantages
Precision is the core benefit: each aperture is identical and stable under load, so filtration cut-points and sieve grading stay consistent over time, unlike woven mesh which can shift. The solid sheet body gives high mechanical strength, letting screens withstand backflushing, vibration and pressure differentials without tearing. Stainless 316L resists aggressive chemicals, salt and high temperatures, suiting food, pharmaceutical and chemical service, and it can be electropolished to a smooth, cleanable, hygienic surface. Screens are easily formed into tubes, cones and baskets and welded into assemblies. When paired as a backing behind fine mesh, the perforated layer carries the structural load while the mesh sets the filtration rating, combining strength and fineness in one element.
Specifications & Options
Fine apertures from 0.5 mm to 5 mm are available in round or square format, with open area typically 20-50% depending on the strength required. Material is most often stainless 304 for general filtration or 316L where corrosion resistance is critical; galvanized steel, aluminum and brass serve specific industries. Thickness ranges 0.5-3 mm. We supply flat screens, pre-rolled cylinders, perforated tubes for filter cartridges, and pressed basket forms, with welded seams and end caps to drawing. Finishes include passivation and electropolishing for hygienic and corrosive duty. Screens can be combined with woven wire mesh as a sandwich or sintered laminate for very fine ratings. Replacement filter elements are matched from existing samples or drawings.
Applications & Industries
Perforated filter screens are found throughout process industry. Water and wastewater plants use them as intake strainers, drum-screen panels and self-cleaning filters; oil, gas and chemical operations use perforated tubes as the core of cartridge and basket filters; food and beverage producers use hygienic stainless screens for juice, oil and syrup filtration and for centrifuge baskets. Pharmaceutical and fine-chemical plants rely on electropolished screens for clean, cleanable separation. The mineral and recycling sectors use them as accurate sieve decks for fine grading. They also serve as the durable support behind fine architectural and filtration mesh. Wherever a consistent, robust, corrosion-resistant separating surface is needed, this screen fits.
Why Choose Zhongman
Zhongman combines perforating and mesh fabrication under one roof, which is a real advantage for filtration customers who need perforated support married to fine wire cloth. We work to aperture tolerances that keep your filtration rating predictable, and we passivate or electropolish stainless to meet hygienic and corrosive-service requirements. Our fabrication shop rolls, welds and presses screens into the cylinders, cones and baskets your equipment needs, then supplies material and weld certificates for audited industries. We reverse-engineer worn filter elements from samples to deliver exact replacements. From a small batch of pharmaceutical baskets to repeat orders of intake screens, we provide consistent quality, documentation and reliable international delivery.
