A40 galvanneal is the most commonly used coating while a60 is less popular because it tends to be too powdery when it sits unpainted too long.
Galvanneal sheet metal thickness.
This is preferred over galvanized if the metal is to be painted.
Galvanneal sheets offers good paintability weldability corrosion resistance and formability.
Galvanneal is the main paintgrip used in the duct fabrication industry taking the place of phos bond which used to be the only option many years ago.
Garfield avenue los angeles ca 90040.
G60 has 0 60 ounces of coating per square foot.
The number in that code refers to the thickness of the zinc coating on the product.
Serving the sheet metal industry in the southeast since 1874 material specification sheet galvanneal steel.
73 slit width tolerance.
This process of extreme heating draws more of the iron out of the steel and causes it to mix with the zinc.
Galvannealed steel has a matte grey color uniform which can be easily painted.
Hot rolled galvannealed steel is derived from the temperature of the alloy when it is rolled into a 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.
010 250 min max slit width.
Spec sheet item codes.
Has no protective film.
The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness.
Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel.
These will vary from british gauges with some exceptions.
Galvannealed steel has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint.
Coating thickness is measured as the coating weight in ounces per square foot.
In comparison to galvanized steel the coating is harder and more brittle.
May have minor scratching.
Our galvanized sheet metal is g60 and we use a40 galvanneal.
Galvanneal steel includes the process of galvanizing with an added step after the zinc coating the steel is heated to around 1050 fahrenheit.
These are ideal thicknesses for most applications and.
For example a40 tells you that the metal contains 0 40 ounces of coating per square foot.
