AS240 Aluminized Steel Sheet with Superior Corrosion and Heat Resistance
AS240 aluminized steel sheet is engineered for demanding environments where extreme heat and corrosion are concerns. With a coating weight of 240 g/sq.m, it delivers outstanding protection, backed by a salt spray test result exceeding 4000 hours. This sheet is ideal for automotive exhaust systems, heat shields, and industrial heating equipment.
Key Selling Points
- 240 g/sq.m coating weight: Offers enhanced corrosion resistance and heat tolerance compared to standard coatings.
- Salt spray test over 4000 hours: Verified durability in corrosive environments, reducing maintenance costs.
- First supplier of 240g coating: MESCO is the first to supply aluminized steel with 240g/sqm coating in the market.
- Excellent heat resistance: Suitable for continuous high-temperature applications above 600°C.
- Proven in automotive exhaust: Used in Mexico for exhaust systems, reducing costs by 30% while lasting 10-15 years.

Models and Options
Available in sheet and coil forms. We can supply various coating weights (AS80, AS120, AS240, AS275, AS300) and sizes to match specific application requirements.
Materials and Structure
The carbon steel substrate provides mechanical strength, while the thicker aluminum-silicon coating forms a robust barrier against oxidation and corrosion, especially at elevated temperatures. This structure ensures lasting performance in harsh thermal and chemical environments.
Applications
- Automotive exhaust systems (mufflers, pipes, heat shields)
- High-temperature industrial equipment
- Heat exchangers
- Chimneys and flues
Customization
We offer cutting, slitting, and custom sizes. For specialized requirements, our engineering team can assist in selecting the optimal coating weight and dimensions.
Case Study
Automotive Exhaust System Project (Mexico)
A Mexican automotive factory relied on AS240 steel for its exhaust systems, achieving excellent heat resistance and cost savings. The material replaced partial stainless steel, reducing raw material costs by nearly 30% while maintaining durability over 10-15 years.
FAQ
How does AS240 compare to AS80?
AS240 has a three times higher coating weight, providing superior corrosion and heat resistance, making it suitable for more demanding applications.
Is AS240 readily available?
Yes, we maintain a large inventory, but specific coating weights may have limited stock; please contact us for current availability.
Can you provide salt spray test certificates?
Yes, we can provide material test reports and third-party inspection certificates upon request.
What are the recommended welding methods?
Conventional welding methods work well; the coating remains stable during welding if proper techniques are used.
Do you offer cutting services?
Yes, we offer slitting and cutting to size to meet your production needs.
