Frequently Asked Questions
-
What materials are available for slotted hole perforated sheets?
We offer galvanized steel, stainless steel (304/316), and aluminum. Hot-dip galvanized is the most common choice for grain drying due to its corrosion resistance and cost-effectiveness. -
Can I get custom slot sizes?
Yes, slot dimensions can be customized from 1mm x 10mm up to 3mm x 20mm. We recommend providing your grain type and airflow requirement for optimal design. -
How do I install these sheets in a drying bin?

What is the typical open area percentage?
Standard open area ranges from 30% to 60%. Higher open area improves airflow but may reduce strength. We can help you select the right balance. -
