Aluminized Coil
Aluminized Coil is available in a wide range of thicknesses from 0.30 mm to 3.00 mm and widths from 600 mm to 1524 mm. Standard coil weights, coating grades, and dimensional tolerances make it suitable for automotive, HVAC, industrial heating, and construction applications. Selecting the correct specification helps optimize fabrication efficiency, durability, and overall product performance.

Description
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, oxidation resistance, and corrosion protection. It is widely used in automotive exhaust systems, industrial heating equipment, 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.
| Thickness (mm) | Thickness (Gauge) | Typical Applications |
|---|---|---|
| 0.30–0.50 | 29–24 Gauge | Ventilation ducts, appliance panels |
| 0.50–0.80 | 24–21 Gauge | Exhaust components, HVAC systems |
| 0.80–1.20 | 21–18 Gauge | Industrial equipment |
| 1.20–2.00 | 18–14 Gauge | Heat shields, structural parts |
| 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.
| Width (mm) | Width (inch) |
| 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
| Item | Typical Range |
| Inner Diameter | 508 mm / 610 mm |
| Outer Diameter | 1000–2000 mm |
| Coil Weight | 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
| Specification | Typical Tolerance |
| Thickness | ±0.02–0.05 mm |
| Width | ±2 mm |
| Length | ±3 mm |
| Flatness | According to standard requirements |
Precise tolerances help ensure stable performance during stamping, bending, and welding operations.
Popular Sizes in Industrial Applications
| Thickness (mm) | Width (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.
