What is the difference between galvanized sheet metal or zinc? The difference is in finish and resistance. The galvanized one is iron with an electroplating process, while the zincalum is covered with an alloy of 55% aluminum and 45% zinc that offers more resistance to corrosion, and its thermal reflectivity is greater.

Which sheet is better for roofing?
Galvanized sheets and Cincalum
Cincalum sheet is an aluminum and zinc alloy, with a formula of 55% aluminum, 1.6% silicon and the rest zinc. This combination offers greater resistance to corrosion, compared to galvanized, they have a longer lifespan of up to 5 times.
What is better galvanized or aluminized sheet metal?
The following advantages stand out: Compared with the galvanized coating, the aluzinc coating increases the useful life of the iron sheet between three and six more years. The presence of silicon in the alloy causes it to increase heat resistance to more than 315 degrees Celsius.
How to know if the sheet is zincalum?
Superficially it presents a well visible crystallization of zinc in the form of a star, called a flower. The Cincalum sheet is an Aluminum-Zinc alloy that offers excellent resistance to corrosion thanks to its formula of 55% Aluminum, 1.6% Silicon and the rest Zinc in proportion to the weight.
What is zinc sheet?
Galvanized sheet metal is a “Zinc” coated metal to prevent metal corrosion. Galvanized is a type of sheet that is installed on all damp and wet floors and has no alternative.

How to make the sheet metal not rust?
The best known and cheapest method of preventing metal corrosion is to cover it with a layer of paint. The corrosion process involves moisture and oxidizing agents that interact with the metal surface.
How to protect galvanizing from corrosion?
When it suffers small wear or adds welding after being galvanized, it tends to become contaminated and thus begin to rust. The fastest and easiest way to protect these areas is by means of a layer of Zinc Paint formulated with a base of high purity metallic zinc.
