Product Description
Maximize your screening efficiency and minimize downtime with our High Manganese Steel Casting Grid Screen Plates. Engineered for the toughest aggregate and mining environments, these grid screen plates are manufactured using premium high manganese steel (Mn13, Mn18) , known for its exceptional work-hardening properties.
Unlike standard steel plates, our cast manganese screen plates become harder and more wear-resistant the more they are impacted by rocks and ores. This makes them the ideal solution for primary scalping, heavy-duty screening, and crusher feeding applications where durability is paramount.
Superior Wear Resistance: Made from high-grade Mn13Cr2 or Mn18Cr2 manganese steel. The surface hardness increases under impact, while the core remains ductile to prevent breakage.
Precision Casting: Utilizing advanced sand casting and lost foam casting technologies to ensure accurate dimensions, smooth surfaces, and uniform grid openings.
Optimized Screening Efficiency: The tapered grid hole design prevents clogging and pegging, ensuring high throughput for materials like iron ore, limestone, granite, and coal.
Longer Service Life: Designed to withstand high-impact abrasion, our screen plates last significantly longer than traditional wire mesh or perforated plates, reducing your replacement costs.
Customizable Design: We offer OEM/ODM services. Whether you need specific slot sizes, hook types, or bolt-down configurations, we can cast screen plates to fit your specific vibrating screen or crusher deck.

Q: What is the difference between Mn13 and Mn18 steel for screen plates?
A: Mn18 (18% Manganese) generally offers higher wear resistance and toughness compared to Mn13, making it better suited for extremely high-impact applications. Mn13 is an excellent cost-effective choice for general heavy-duty screening.
Q: Can you manufacture screen plates based on my drawings?
A: Yes, we specialize in custom casting. Please send us your technical drawings or a sample, and we will produce the grid screen plate to your exact specifications.
Q: What is the lead time for a custom order?
A: Typically, production takes 15-25 days depending on the quantity and mold complexity.
