Aluminized Steel
Shaw Steel stocks and processes aluminized steel for applications that require a dependable combination of heat resistance, corrosion protection, and reliable performance in demanding service environments. We help customers source the right aluminized product based on application, fabrication needs, and end-use conditions.
Key Benefits of Aluminized Steel
Aluminized steel is commonly used when an application calls for a balance of thermal performance, corrosion protection, and fabrication capability. Final performance depends on coating type, gauge, environment, and how the part will be processed and used.
- Heat resistance: Often used in elevated-temperature applications where oxidation resistance matters.
- Corrosion protection: The aluminum-based coating helps protect the steel substrate in many service environments.
- Reflective surface: Useful in some applications involving radiant heat or thermal management.
- Formable and weldable: Frequently used in fabricated and formed assemblies, depending on the part design and process.
It is steel coated with an aluminum-based layer to help improve heat resistance, corrosion performance, or both depending on the coating type and application.
Type 1 is typically aluminum-silicon and is often used for higher-temperature service, while Type 2 uses commercially pure aluminum and is often selected for corrosion resistance.
Typical applications include exhaust-related components, heat shields, HVAC parts, appliance components, panels, and protective enclosures.
We help customers align coating type, thickness, width, form, and processing requirements with the actual service environment and fabrication plan.
Aluminized Coating Types
Coating selection depends on how the material will perform in service, how it will be fabricated, and what kind of heat or corrosion exposure the final part will experience.
Type 1 (Aluminum-Silicon)
Type 1 is commonly used in applications where high-temperature performance is important. It is often considered for components exposed to heat, oxidation, or thermal cycling.
Type 2 (Commercially Pure Aluminum)
Type 2 is often selected for corrosion resistance in general service applications. The right choice depends on the operating environment, fabrication method, and end-use expectations.
Common Applications for Aluminized Steel
Aluminized steel is often used where customers need a coated flat-rolled product that can perform reliably in heat-related or corrosion-sensitive applications.
Automotive Exhaust Components
Commonly evaluated for parts where heat resistance and oxidation performance are important.
Heat Shields
Often used where reflective surface properties and elevated-temperature performance are part of the design requirement.
HVAC Ducting and Venting
Can be used in systems that require a durable metallic-coated surface with thermal performance considerations.
Appliance and Industrial Components
Frequently considered for heat-related parts, enclosures, and formed components in industrial applications.
Outdoor Panels and Housings
May be selected where corrosion resistance and appearance both matter depending on the environment.
Protective Covers and Enclosures
Useful in applications where customers need a practical mix of coating performance and fabrication capability.
Typical Aluminized Supply Considerations
Supply range depends on mill program, coating type, thickness, width, and processing route. The table below gives a directional overview rather than a fixed inventory promise.
| Parameter | Typical Range | Notes |
|---|---|---|
| Form | Coil, slit coil, sheet, blanks | Processed to order based on application and production needs. |
| Thickness / Gauge | Varies by coating type and mill availability | Best confirmed by target thickness, end use, and current sourcing route. |
| Width | Varies by coil program | Slit-to-width options may be available depending on the requirement. |
| Coating Type | Type 1 or Type 2 | Selection should match the service environment and fabrication plan. |
| Surface | Metallic aluminized finish | Appearance may vary by coating, mill source, and handling conditions. |
If you share the application environment, heat exposure, corrosion concerns, forming needs, and welding or finishing requirements, Shaw Steel can help recommend the best aluminized option.
Processing and Support
Processing Options
We can support aluminized programs with slitting, cut-to-length sheets, blanks, shearing, tension leveling, and shape correction depending on the job requirements.
Surface-Conscious Handling
Packaging, storage, and handling can be important for aluminized material, especially when appearance or surface consistency matters.
Quality and Documentation
MTR traceability, grade alignment, and documentation support can help customers verify the material against their print and specification needs.
Logistics Coordination
We help align delivery windows, order form, and release timing with the customer’s production schedule and inventory requirements.
What to Share for the Best Quote
To quote aluminized steel accurately, it helps to provide the coating type, thickness, width, required form, quantity, and delivery timing. If the material will be formed, welded, or exposed to elevated heat or outdoor conditions, those details help us recommend the right sourcing path.
Shaw Steel works with customers to align the material and processing plan with the real performance needs of the application.

Aluminized FAQs
What is the difference between aluminized Type 1 and Type 2?
Type 1 is typically used where higher-temperature performance matters, while Type 2 is more often selected for general corrosion resistance. The best option depends on the specific application and service environment.
Can aluminized steel be formed and welded?
Yes, aluminized products are often formed and welded, but success depends on coating type, thickness, part geometry, and process conditions. Sharing fabrication details helps ensure the material is matched correctly.
Will aluminized steel rust?
The aluminum-based coating provides protection, but real-world performance depends on cut edges, exposure conditions, handling, design details, and the service environment.
Do you offer coil, slit coil, sheets, and blanks?
Yes. Shaw Steel can support aluminized steel in multiple forms depending on the order, processing needs, and sourcing program.
