Perforated Sheets
Rectangle Hole Perforated Sheet
Specifically configured for linear material separation and heavy screening, our Rectangle Hole Perforated Sheets offer high throughput and exceptional sorting accuracy. These slot patterns are designed with robust bridge dimensions to withstand intense mechanical stress and abrasion. Available in varied staggered or straight configurations, each sheet is flattened and stress-relieved to meet strict industrial flat-tolerance standards.
Key Features
Designed for high-throughput linear material flow and sorting
Highly resistant to blind-clogging under heavy material loads
Compliance with global ASTM and ISO industrial standards
Mill test certifications confirming mechanical properties and material grade
Common Applications
Heavy-duty mining screens and coal sorting systemsAgricultural grain separation and seed cleaning millsHigh-velocity industrial ventilation louvers and air ductsChemical processing and wastewater sorting grates
