Descrizione
Aluminized Coil is produced by coating carbon steel with an aluminum-silicon alloy through a continuous hot-dip process. The material combines the strength of steel with excellent heat resistance, Resistenza all'ossidazione, e protezione dalla corrosione. È ampiamente utilizzato nei sistemi di scarico automobilistici, apparecchiature di riscaldamento industriale, construction materials, and HVAC applications.
One of the most important considerations when selecting aluminized steel products is choosing the appropriate thickness, width, and coil dimensions for the intended application.
Common Thickness Range
The thickness of aluminized coil varies according to industry requirements.
| Spessore (mm) | Spessore (Misura) | Applicazioni tipiche |
|---|---|---|
| 0.30–0.50 | 29–24 Gauge | Condotti di ventilazione, appliance panels |
| 0.50–0.80 | 24–21 Gauge | Exhaust components, Sistemi HVAC |
| 0.80–1.20 | 21–18 Gauge | Industrial equipment |
| 1.20–2.00 | 18–14 Gauge | Scudi termici, parti strutturali |
| 2.00–3.00 | 14–11 Gauge | Heavy-duty industrial applications |
Common Width Specifications
Most manufacturers offer standard widths suitable for coil processing and sheet production.
| Larghezza (mm) | Larghezza (pollice) |
| 600 | 23.6 |
| 914 | 36 |
| 1000 | 39.4 |
| 1219 | 48 |
| 1250 | 49.2 |
| 1500 | 59 |
| 1524 | 60 |
Custom widths can also be slit according to customer requirements.
Coil Dimensions
| Articolo | Gamma tipica |
| Inner Diameter | 508 mm / 610 mm |
| Diametro esterno | 1000–2000 mm |
| Peso della bobina | 3–25 Tons |
| Coil Length | Customized |
The actual coil dimensions depend on thickness, width, and transportation requirements.
Common Coating Weights
The aluminum-silicon coating weight affects corrosion resistance and service life.
| Coating Grade | Total Coating Weight (g/m²) |
| AS60 | 60 |
| AS80 | 80 |
| AS100 | 100 |
| AS120 | 120 |
| AS150 | 150 |
Higher coating weights generally provide enhanced durability and oxidation resistance.
Typical Production Tolerances
| Specifica | Typical Tolerance |
| Spessore | ±0.02–0.05 mm |
| Larghezza | ±2 mm |
| Lunghezza | ±3 mm |
| Flatness | According to standard requirements |
Precise tolerances help ensure stable performance during stamping, flessione, and welding operations.
Popular Sizes in Industrial Applications
| Spessore (mm) | Larghezza (mm) |
| 0.47 | 1219 |
| 0.60 | 1219 |
| 0.80 | 1219 |
| 1.00 | 1219 |
| 1.20 | 1219 |
| 1.50 | 1250 |
| 2.00 | 1500 |
These dimensions are commonly used for automotive exhaust systems, industrial furnace components, ventilation equipment, and heat-resistant fabrication projects.
