The What and Why of Aluminized Steel Sheets

Aluminized Steel

Aluminized steel sheets are sheets of steel treated with an aluminum-silicon alloy. This causes the aluminum and steel to bond that gives the metal unique properties of both metals. Aluminized steel has a higher corrosion resistance and can hold the properties of steel in strength and durability under temperatures less than 800 Celsius. Usually, the steel is used in water heaters, furnaces, heat exchangers, vehicle mufflers, ovens, fireplaces, barbecue grills, stoves, corrugated roofing, air conditioning housing, drying ovens, building siding, storage bins, and baking pans.

Aluminized steel sheets provide many benefits over plain steel. First of all, the aluminum coating protects the interior steel from corrosion. The silicone bond between the two metals helps the metals bond and become similar to one solid metal that obtains the best properties of both metals. Many factories choose to work with aluminized steel over other metals because it is cheaper to manufacturer than other forms of high-yield steel, while still maintaining the best properties of these other metal alloys.

A factory can manufacturer aluminized steel in a variety of ways, including hot dipping, galvanizing, cladding, metalizing, or calorizing. Hot dipping, however, is generally the most effective method for creating consistent results.

With non-corrosive steel, factories can use the metal sheets in many applications that would otherwise require more expensive metals, such as stainless steel. The rugged and tough nature of the metal mix makes it ideal for many high-intensity uses, such as industrial containers and machines, and outdoor uses, such as roofing and automotive manufacturing. Because of the inexpensive nature of the metal blend, many automotive companies use aluminized steel sheeting in automotive manufacturing to provide exceptional performance for less expense.
