As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Custom Perforated Metal Sheet for Agricultural Grain Dryer. Engineered specifically for the demanding environment of grain drying systems, this 1.5mm thick sheet with 4mm holes offers exceptional anti-corrosion performance and long-lasting durability. Our factory, established in 1998 and exporting over US$5 million annually, delivers precision-engineered perforated metal solutions that optimize airflow while protecting grain quality. Whether you need standard sizes or fully customized dimensions, we provide the reliability and consistency your agricultural operations require.
This product is designed to withstand harsh conditions, including high humidity, temperature fluctuations, and exposure to grain dust. The 1.5mm base thickness ensures structural integrity even under heavy loads, while the 4mm round holes are strategically arranged to maximize airflow for efficient drying without allowing grain kernels to pass through. The anti-corrosion coating — available in hot-dip galvanized, powder-coated, or painted finishes — provides a robust barrier against rust and chemical reactions from fertilizers or moisture. With our customizable sheet sizes and hole patterns, we can match any grain dryer model, from small mobile units to large industrial towers.
Key Features & Technical Specifications
- Precision Punched Holes: 4.00 mm ±0.1 mm diameter, available in staggered or straight row patterns to achieve desired open area (typically 40%-58%).
- Thickness Consistency: 1.5 mm (14 gauge) with tight tolerance (±0.05 mm) for uniform strength across the sheet.
- Anti-Corrosion Protection: Multiple treatment options — hot-dip galvanized (HDG), electro-galvanized, zinc-rich paint, or epoxy powder coating — all tested to resist salt spray and humidity.
- Material Options: Carbon steel (Q235, SPCC), stainless steel (304, 430), or galvanized steel (DX51D+Z) to suit different budget and corrosion resistance needs.
- Custom Dimensions: Width from 500 mm to 1500 mm, length from 1000 mm to 6000 mm, or cut to exact specifications. Thickness can be adjusted from 0.8 mm up to 3.0 mm.
- Edge Finishing: De-burred and smooth edges to prevent injury during handling and installation, with optional hemmed or rolled edges.
- Load Capacity: Designed to withstand static loads up to 200 kg/m² (depending on support spacing) for grain dryer applications.

Benefits for Your Grain Dryer Application
- Optimized Airflow: The 4mm holes combined with 48% open area allow hot air to circulate freely through the grain bed, reducing drying time and energy consumption by up to 15% compared to solid panels.
- Long Service Life: Anti-corrosion treatment ensures the sheet remains rust-free for 5–10 years in typical agricultural environments, lowering replacement costs.
- Grain Retention: 4mm holes prevent loss of corn, wheat, soybeans, and other common grains while allowing fine dust to pass through.
- Easy Installation: Lightweight yet rigid — 1.5mm thickness provides sufficient strength without excessive weight, simplifying handling and mounting.
- Versatile Customization: We can punch holes in any pattern, cut to non-standard shapes, or add mounting flanges to match your dryer's frame.
- Cost-Effective: Direct factory pricing with annual export volume of US$5–10 million ensures competitive rates without compromising quality.

We offer a satisfaction guarantee — if the product does not match the agreed specifications, we will replace it at no extra cost.
Frequently Asked Questions
Q: What anti-corrosion options are available for this perforated sheet?
A: We offer hot-dip galvanized (HDG), electro-galvanized, zinc-rich paint, and powder coating (various colors). The most common choice for grain dryers is HDG with a zinc coating weight of 275 g/m², providing excellent resistance to moisture and ammonia. For more aggressive environments, we recommend stainless steel 304 with a brushed finish.
Q: Can you supply sheets longer than 6 meters?
A: Yes, we can produce up to 8 meters in length for special orders, but please note that longer sheets may require thicker material or additional support to prevent sagging. Contact our sales team with your specific dimensions.
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes and materials, MOQ is 50 sheets. For custom dimensions or special coatings, MOQ is 100 sheets. However, we can accommodate sample orders (1–5 sheets) for testing purposes.
Q: How do you ensure the holes are clean and free of burrs?
A: Our punching dies are precision-ground and maintained regularly. After punching, each sheet passes through a deburring machine that removes sharp edges. We also offer an optional roller-leveling process for perfectly flat sheets.
Q: Can you match the hole pattern of my existing dryer screen?
A: Absolutely. Send us a sample or a technical drawing with dimensions, hole pattern, and pitch. We can replicate the pattern exactly, or suggest improvements for better airflow or strength.
Q: What is the typical lead time?
A: For standard sizes and materials, production takes 7–10 working days. Custom orders require 15–20 working days, plus shipping time. We can expedite urgent orders upon request.
Q: Do you provide free samples?
A: Yes, we offer free samples (A4 size or 200x200 mm) for evaluation. The customer only pays for shipping. Sample production takes 3–5 days.
Q: How do you pack the sheets for export?
A: Sheets are interleaved with protective paper or plastic film, then bundled on wooden pallets with steel strapping. For extra protection, we can shrink-wrap the pallets or use customized crates. All packaging is suitable for sea freight.
