Galvanneal Steel Sheet

In comparison to galvanized steel the coating is harder and more brittle.

Galvanneal steel sheet.

As the metal strip exits the coating bath the zinc is subjected to an in line heat treatment that converts the entire coating to a zinc iron alloy giving the sheet improved surface finish so it. Applications of galvanneal vary widely because many different types of steel can be galvannealed. Galvannealed sheet can be formed much in the same way and by the same variety of processes as galvanized sheet. Hot rolled steel is steel that has been heated above its recrystalization point and is pushed between two rollers to meet a certain length and thickness.

Galvannealed steel is carbon steel coated with zinc using a hot dipped process. For instance a thin low carbon steel may be galvannealed and made into a bracket on an automobile frame while a thick high strength low alloy steel may be galvannealed and used in the structure of a. This allows for the galvannealed steel to be more ductile and flexible. Galvannealed steel is readily paintable.

Hot rolled galvannealed steel is derived from the temperature of the alloy when it is rolled into a sheet. The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance. Galvannealed or galvanneal galvannealed steel is the result from the processes of galvanizing followed by annealing of sheet steel. Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel.

As a result some amount of powdering can appear when the metal is formed. Galvannealed steel is a matte uniform grey color which can be easily painted.
