Core Product Features
Thick plate stainless steel perforated sheets, as crucial screening and filtration materials in industrial fields, demonstrate unique advantages in industries such as chemical engineering, mining, and food processing:
Exceptional Durability: 3-20mm thickened base plates combined with precision punching processes extend service life by 3-5 times compared to standard screens.
Environmental Adaptability: Withstands temperatures from -50°C to 800°C and extreme conditions like strong acids/alkalis (pH 1-14).
Customized Production: Supports non-standard sizing, with maximum manufacturable dimensions up to 3m×6m.
Key Parameter Details
Plate Thickness Selection
3-6mm: Suitable for light-duty scenarios like food-grade filtration or architectural decoration, with load capacity of 1200-2500kg/m².
8-12mm: Designed for mine gravel screening, withstands impact loads up to 6000kg/m².
14-20mm: Used in heavy-duty environments like oil-gas separation and chemical reactors, with ultimate load capacity reaching 12000kg/m².
Stainless steel Perforated sheet
Hole Design Essentials
Round Holes (3-50mm diameter): Most cost-effective solution, adjustable open area ratio of 25%-70%.
Obround Holes (aspect ratio 2:1 to 5:1): Ideal for fibrous material screening with significant anti-clogging effects.
Hexagonal Holes: Honeycomb arrangement enhances structural strength by 30%, commonly used in vibratory screens.
Diamond Holes (10-60mm diagonal): Primarily for decorative ventilation structures in building curtain walls.
Material Comparison
201 Stainless Steel: Budget-friendly option for dry indoor environments (e.g., warehouse ventilation partitions).
304 Stainless Steel: Preferred for food/pharmaceutical industries, achieves Ra0.8μm surface finish via electropolishing.
316L Stainless Steel: Molybdenum-enhanced with 50% improved seawater corrosion resistance, ideal for coastal projects.
430 Stainless Steel: Excellent high-temperature oxidation resistance, widely used in thermal power plant flue gas systems.
Engineering Application Examples
1.Refinery Application: 14mm-thick 316L catalyst recovery screens with 10mm apertures in triangular patterns.
2.Wastewater Treatment: 304 stainless steel diamond-hole screens achieve 60% open area for efficient solid-liquid separation.
3.Food Processing: 6mm-thick 2B finished perforated plates for starch production vibratory screening machines.
4.Architectural Decoration: Custom artistic-pattern perforated curtain wall panels combining ventilation and aesthetics.
