The Edge-Folded Screen Mesh is a screening medium whose edges are strengthened through special processes such as folding, locking, or encapsulating. The mesh edges are folded and firmly fixed to a metal or polymer frame, or directly reinforced to form a robust hooked-edge structure. It is compatible with various screening equipment including vibrating screens, linear screens, and rotary drum screens.
Its core advantage lies in its edge-reinforcement design, solving the common problems of traditional mesh—such as edge wear, wire unraveling, and unstable installation—while maintaining screening precision and structural stability. It is widely used in material classification, solid–liquid separation, and impurity filtration. The edge structure, mesh material, and aperture size can all be customized based on working conditions.
Using techniques such as folded-edge locking with welded reinforcement or polymer edge encapsulation, the mesh edge tensile strength increases by over 50%, preventing failures caused by unraveling or edge breakage. For example: Stainless steel edge-folded mesh with double-layer folded welding can withstand ≥300 N of tensile force without tearing. Nylon mesh with integrated injection-molded edges offers 3× the wear resistance of conventional mesh and extends service life by 2–4×, reducing replacement frequency and cost.
The edge-folded structure aligns precisely with equipment slots or bolt holes, requiring no trimming or extra fixtures. One mesh panel can be installed in ≤3 minutes, reducing labor time by more than 60%. Custom options include: Edge width (10–50 mm), Edge shapes (right-angle, rounded), Fixing methods (clip-on, bolted). This ensures perfect compatibility with mainstream equipment and solves issues such as trimming difficulty and installation misalignment seen with loose mesh.
The reinforced edge maintains uniform mesh tension and a flat screening surface, ensuring even material distribution and preventing leakage caused by edge loosening.
The mesh is manufactured using precision weaving, perforation, or wedge-wire processes with aperture tolerance ≤±2%, covering 1–500 mesh and enabling accurate classification from 5 microns to 200 mm. The tight edge-equipment seal further ensures consistent screening accuracy, ideal for applications requiring high purity.
The integrated “edge support + central screening” design provides structural stability under conditions like heavy impact and high-frequency vibration.
For example, in mining coarse screening:
Manganese-steel edge-folded mesh withstands direct impact from ore ≥100 mm.
Mesh surface deformation is ≤2 mm, much lower than the 5–8 mm typical of conventional mesh.
This ensures long-term stable operation.
Available materials include stainless steel (304/316L), manganese steel (65Mn), nylon (PA66), polyurethane, etc. Edge materials can match or combine with mesh materials (e.g., stainless mesh + carbon-steel edge, nylon mesh + polymer edge). Suitable for high temperatures (≤300°C), low temperatures (–60°C), corrosive environments, and high-wear conditions.Example: 316L stainless steel mesh handles strong acid/alkali (pH 1–14). Nylon edge-folded mesh meets hygienic screening requirements for food and pharmaceutical industries.
Used for coarse, medium, and fine screening after ore crushing (e.g., granite, limestone), compatible with circular and linear vibrating screens. Manganese-steel mesh handles large impact loads. Stainless steel mesh is used in screening non-ferrous ores (copper, gold, silver) to prevent contamination. In aggregate production, edge-folded mesh ensures accurate control of particle sizes such as 5–10 mm and 10–20 mm for concrete and asphalt applications.
Used to separate lump and fine coal, remove gangue, and filter impurities in coal mining, compatible with vibrating screens and jigs. Carbon-steel mesh is economical and durable for general coal screening. 316L stainless mesh supports solid–liquid separation in coalbed methane drilling fluids, resisting chemical corrosion. In power plants, it filters large impurities in fuel coal to protect boiler systems.
Used for grain cleaning and quality grading (e.g., removing stones and stalks from wheat or rice), and fine screening of flour and starch. Food-grade nylon and 304 stainless steel comply with FDA and GMP standards, preventing contamination. In pharmaceuticals, it is used for grading herbal materials and screening fine powders to ensure consistent particle size.
Used for particle size control of chemical raw materials (plastic pellets, resin, pigments) with high-frequency screens. 316L stainless mesh resists strong acids and alkalis such as HCl and H₂SO₄.Polyurethane edge-folded mesh is hydrolysis-resistant, suitable for water-based coatings and adhesives. In environmental applications, it handles sludge dewatering and wastewater pretreatment without releasing metal ions into water.
Used for screening impurities from cement, lime, gypsum, etc., compatible with vibrating and airflow screens. Carbon-steel mesh withstands high abrasion from building materials.
In construction waste recycling, edge-folded mesh separates concrete blocks, rebar, and soil, and its reinforced edges prevent puncture damage from sharp debris.
The edge-folded screen mesh, with its edge-reinforcement core design, solves the traditional limitations of loose mesh in durability, installation convenience, and screening stability. It offers the combined advantages of structural strength and screening precision.
With flexible material combinations and customized designs, it adapts to complex working conditions across mining, coal, food, chemical, and environmental industries. Whether handling heavy abrasive materials or meeting hygienic fine-screening requirements, it ensures reliable performance, improved efficiency, and lower maintenance costs.
As a “reinforced” screening medium, the edge-folded mesh has become the preferred solution for industrial users seeking efficient and stable production.
