Aluminized Stainless Steel

Aluminized stainless steel is a kind of stainless steel treated by a hot-dip coating process on both sides with aluminum-silicon alloy. This process enhances the aesthetic appeal and significantly extends the service life compared to bare stainless steel. In addition, the product is weldable and can be easily fabricated into various exhaust components.
