An A3003 H44 perforated aluminum sheet is a metal panel made from the 3003 aluminum-manganese alloy. Factory machines punch various hole patterns into the metal. The "H44" refers to the specific temper (hardness condition) of the aluminum, which means it is strain-hardened and stabilized.
Because it offers much better strength than pure aluminum (like the 1100 series) and resists rust naturally, buyers widely use this material for architectural building facades, industrial ventilation, and noise control panels.
Chemical Composition of 3003 Aluminum
The secret to 3003 aluminum's performance is what is inside it. By adding Manganese, the metal becomes significantly stronger without losing its anti-rust features.
| Element (%) | Content |
| Aluminum (Al) | Balance |
| Manganese (Mn) | 1.0 – 1.5 |
| Copper (Cu) | 0.05 – 0.20 |
| Silicon (Si) | ≤ 0.6 |
| Iron (Fe) | ≤ 0.7 |
| Zinc (Zn) | ≤ 0.10 |
Mechanical Properties of 3003 H44 aluminum
Engineers look at these mechanical numbers to ensure the metal can handle outdoor wind pressure and heavy loads.
| Property | Value (H44 Temper) |
| Tensile Strength | 140 – 180 MPa |
| Yield Strength | ≥ 120 MPa |
| Elongation | ≥ 8% |
| Hardness Level | Medium-High |
The data shows that A3003 H44 has excellent yield strength. The elongation rate (≥ 8%) means the metal is flexible enough to be punched quickly by machines without cracking the hole edges.
A3003 H44 vs. A3003 H14
Many buyers get confused between H14 and H44. Here is a direct comparison to help you make a purchasing decision:
| Feature | A3003 H14 | A3003 H44 |
| Structural Strength | Medium | Higher |
| Internal Stability | Normal | Better (Stabilized) |
| Flatness After Punching | Good | Excellent |
| Best Application | General indoor decoration | Outdoor facades & structural panels |
The Buying Rule: If you need simple decorative panels indoors, H14 is fine. However, if you are buying large perforated panels for outdoor building facades or heavy-duty engineering projects, A3003 H44 is highly recommended because it stays perfectly flat and is safer.

Perforation Performance in the Factory
Because A3003 H44 combines good hardness with internal stability, it performs exceptionally well during the CNC punching process:
- Punching Ability: Very good. It does not easily damage the machine's punching pins.
- Hole Edge Quality: Clean and smooth. No sharp metal burrs are left on the edges.
- Crack Resistance: Good. The metal will not break even when punching closely spaced holes.
- Flatness: Excellent. Needs very little leveling work after production.
Common Hole Patterns Available
GNEE can punch almost any pattern into A3003 H44 sheets. The most common choices include:
- Round Hole: The cheapest and most popular. You can choose staggered (triangle layout for strength) or straight layouts.
- Square Hole: Provides the highest open area for maximum airflow.
- Slotted Hole: Long oval holes, mainly used for sorting materials or industrial water drainage.
- Custom Patterns: We can cut decorative shapes like stars, hexagons, or specific architectural designs using CAD drawings.
Typical Applications A3003 H44 Perforated Aluminum Sheet
Because it is light, rust-proof, and strong, A3003 H44 perforated metal is used everywhere in modern life.
Architecture and Decoration:
- Curtain wall facades for commercial high-rise buildings.
- Outdoor sunshade panels to block heat but let wind pass.
- Acoustic ceiling panels in airports or large halls.
Industrial Uses:
- Heavy-duty filtration screens for water and oil.
- Safety machine guards in factories (protecting workers from moving parts).
- Ventilation covers for large generator rooms.
Traffic and Infrastructure:
- Noise barrier walls along busy highways.
- Anti-slip walkways and platform panels in outdoor power plants.

Safe Export Packaging and Logistics
A common problem in international trade is that metal sheets arrive bent, scratched, or wet. At GNEE, we use strict export-standard packaging to protect your goods:
- Pallets: Strong, seaworthy wooden pallets.
- Moisture Protection: We wrap the metal tightly in waterproof kraft paper and heavy PE plastic film.
- Safety Details: We add hard edge protectors and lock the bundles with heavy-duty steel strapping.
- Customs Friendly: All wooden materials include the ISPM 15 Fumigation Certificate for fast port clearance.
- Optional Services: We can add protective PVC film directly onto the metal surface to stop scratches during your installation.
