Galvanized steel is formed via a hot dipped galvanizing method which coats steel with a light zinc layer.
Galvannealed sheet metal las vegas.
Immediately after the hot dip process the metal is exposed to a heat treatment that allows the iron from the base metal to further diffuse into the zinc creating a zinc iron alloy layer.
One notable process called galvannealing.

The metalwest las vegas nev branch opened its doors in 1996.
The steel is then taken to a molten bath of zinc at extreme temperatures of approximately 860 f 460 c.
Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel.
Galvannealed steel is created by a hot dip coating process.
Steel sheet backer coats to enhance corrosion resistance and figure 1 minimize abrasion damage initial sr value of 0 25 or higher for steep slope more than 2 12 roofs and 0 15 or higher after 3 years or an initial sr value of 0 65 or higher for low slope 2 12 or.
Galvannealed steel has a matte grey color uniform which can be easily painted.
There are however several different processes to apply this zinc layer.
It is vastly used for many miscellaneous applications.
What is galvanizied steel.
In comparison to galvanized steel the coating is harder and more brittle.
A particularly popular combination is coating carbon steel with a layer of zinc known as galvanized steel.
Serving the greater las vegas area we are a sheet metal specialist in carbon and non ferrous steel including aluminum and stainless coil and sheet.
This allows for the galvannealed steel to be more ductile and flexible.
Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel.
Sacrificial coatings are an excellent way to protect an underlying base material from the effects of corrosion.
Hot rolled galvannealed steel is derived from the temperature of the alloy when it is rolled into a sheet.
The process produces a uniform zinc coating on both sides of the product.
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.
