Where Is Heavy 3003 Expanded Aluminum Mesh Used?
Heavy aluminum expanded mesh is specified wherever a facade must stay ventilated and lightweight: exterior cladding and sunshade screens on commercial buildings, curtain wall infill panels, and decorative interior ceilings.
- Building facade
- curtain wall
- ceiling decoration
Metallurgical Composition & Alloy Ratio Analysis
3003-H14 Aluminum Purity & Traceability
Every plate batch for this family is 3003 aluminum in H14/H24 temper, spectrometer-verified before expansion. The Mn 1.0-1.5% addition roughly doubles the strength of pure 1060 aluminum while keeping the self-healing oxide film that protects exterior facades, and each shipment includes an EN 10204 3.1 mill certificate tied to the plate heat number per ASTM B209, so the alloy behind this heavy aluminum expanded mesh is always traceable.
All batches are tested via handheld PM-I spectrometer before Tianjin Port export, guaranteeing material compliance.
3003-H14 Physical & Service Limits
- Yield Strength:115 MPa minimum in H14 temper per ASTM B209, keeping 2-3 mm facade panels rigid across framing spans without oil-canning.
- Weight Advantage:Density 2.73 g/cm³, about one third of steel, so the 3 mm SKU at 4.5 kg/m² cuts subframe load and simplifies site handling versus steel expanded metal.
- Finish Compatibility:Accepts anodizing, polyester powder coating and PVDF systems after standard pretreatment, with no red-rust risk at sheared edges.
- Service Limit:Mechanical properties hold in normal facade conditions; avoid sustained exposure above 150°C where 3003 begins to lose temper strength.
Which EMMA 557 and ASTM B209 Tolerances Apply to 3003 Expanded Panels?
Two standards govern this family: ASTM B209 controls the 3003 plate alloy and thickness, while NAAMM EMMA 557 controls the expanded geometry (SWD/LWD), squareness and camber. Confirm the applicable tolerance in your purchase order or incoming inspection plan, and request actual measured values in the pre-shipment report.
| Characteristic | Reference Standard | Standard Tolerance | Verified At |
|---|---|---|---|
| Plate thickness (2.0-3.0 mm) | ASTM B209 | ± 0.10 mm | Mill certificate plus batch micrometer check |
| Design size SWD / LWD | NAAMM EMMA 557 | -0, +1/2 in. per foot | Pre-shipment dimensional report |
| Out of square & camber | NAAMM EMMA 557 | 1/16 in. per foot of width/length | Flatness check before packing |
