As a leading manufacturer from Anping Xinye Metal Wire Mesh Products Co., Ltd in Hengshui, Hebei, China, we specialize in producing high-quality 1.2mm Thick Aluminum Perforated Metal Sheet with precise 5mm slot holes and a consistent 50% open area. Our product is designed to offer a perfect balance of strength, lightweight construction, and excellent airflow or light transmission. Whether you need standard panels or fully customized sizes, our factory can deliver perforated sheets tailored to your exact project requirements.
This perforated aluminum sheet is manufactured using advanced CNC punching technology, ensuring each slot is uniform in shape and spacing. The 1.2mm thickness provides adequate rigidity for structural applications while remaining easy to cut, bend, or weld. With a 50% open area, it maximizes ventilation and visibility, making it ideal for architectural facades, security screens, machine guards, and acoustic panels. The aluminum material is naturally corrosion-resistant, lightweight, and fully recyclable, contributing to sustainable building practices.
Key Features & Technical Specifications
- Precision Perforation: Slot holes are cleanly punched with 5mm width and customizable length (typically 10–20 mm), with a center-to-center spacing that ensures exactly 50% open area.
- Material Grade Options: Available in Aluminum 1060, 3003, 5052 alloys – choose based on your required strength, formability, or corrosion resistance.
- Custom Dimensions: We can cut sheets to any size from small panels (200×200 mm) up to large formats (1500×3000 mm). Tolerances of ±1 mm on length/width are standard.
- Surface Finishes: Mill finish (natural silver) is standard. Optional anodizing, powder coating, or PVDF painting is available upon request to match your color specifications.
- Edge Treatment: Deburred edges for safe handling; no sharp burrs left behind.
- Durable & Lightweight: Approximately 2.7 kg/m² for 1.2mm thickness (varies with open area), making it easy to transport and install without heavy support structures.
- Wide Application: Used in building cladding, sunshades, ceiling panels, ventilation grilles, filter screens, speaker grills, and industrial machinery guards.

Advantages for Your Projects
- Enhanced Ventilation: The 50% open area allows maximum airflow while maintaining structural integrity – ideal for HVAC grilles, ventilation panels, and acoustic treatments.
- Light Control: Slot holes provide directional light diffusion, making them suitable for sunshades and decorative screens that reduce glare without blocking natural light.
- Corrosion Resistance: Aluminum naturally forms a protective oxide layer, so no additional coating is needed for indoor or normal outdoor environments. For coastal areas, anodized finish is recommended.
- Easy Fabrication: The 1.2mm thickness is easy to cut with standard tools, and the material can be bent, welded, or riveted without cracking. Custom shapes (curved, folded) can be produced upon request.
- Cost-Effective: Compared to stainless steel, aluminum is more affordable and lighter, reducing shipping and installation costs. The 50% open area uses less material, further lowering the unit price.
- Eco-Friendly: Aluminum is 100% recyclable, and our production process minimizes waste. Many architects choose perforated aluminum for LEED-certified projects.

Frequently Asked Questions
-
What is the maximum sheet size you can produce?
Our standard maximum is 1500 mm × 3000 mm, but we can also supply smaller panels or cut-to-size pieces. For larger sizes, we can discuss coil or slit options. -
Can you provide a sample before bulk order?
Yes, we offer free samples (A4 size or 200×200 mm) for evaluation. You only need to pay the express shipping cost. Samples are usually dispatched within 3 working days. -
How do you ensure the 50% open area is accurate?
Our CNC punching tools are programmed based on the hole pattern calculation. We measure the open area using a digital scanner on each production batch to guarantee ±2% tolerance. -
Is this aluminum sheet suitable for outdoor use?
Yes, aluminum is naturally corrosion-resistant. For harsh coastal or industrial environments, we recommend anodizing or powder coating for extra protection. -
What packaging do you use for export?
Sheets are packed in wooden crates or pallets with protective foam and cardboard between layers. For long distances, we use waterproof paper and steel strapping to prevent damage. -
Can you produce slot holes with different lengths or staggered patterns?
Absolutely. The slot length, spacing, and arrangement (linear, staggered, 45° offset) are all customizable. Please provide a drawing or sample for reference. -
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is 50 sheets (or 100 m²). For custom sizes, MOQ may be higher depending on setup complexity. We also accept trial orders for small quantities. -
Do you offer any certification for material quality?
We can provide a mill test certificate for the aluminum alloy composition upon request. Our factory follows ISO 9001 quality management system (internal standards).
