Pre-Galvanized Steel - All siderails and rungs shall be of steel conforming to the requirements of ASTM A653/A653M-06a with G90 coating thickness. Siderail shall be reinforced with flanges turned inward.

 

Pre-Galvanized:

Pre-galvanized, also known as mill-galvanized or hot dip mill-galvanized, is produced in a rolling mill by passing steel coils through molten zinc. These coils are then slit to size and fabricated.

Areas not normally coated during fabrication, such as cuts and welds, are protected by neighboring zinc, which works as a sacrificial anode.

During welding, a small area directly affected by heat is also left bare, but the same self-healing process occurs.

G90 requires a coating of .90 ounces of zinc per square foot of steel, or .32 ounces per square foot on each side of the metal sheet.

In accordance with A653/A653M-06a, pre-galvanized steel is not generally recommended for outdoor use or in industrial environments. 

Products Pre Galvanized (PG) before manufacture should always be protected and stored in a well ventilated and dry location, and stacked as below.All metallic products should be stored undercover in a dry, unheated environment and be loosely stacked off the ground to ensure adequate ventilation. It is important that products that have different finishes are kept apart.

A zinc coating can be economically applied to steel sheet immediately after its manufacture; the result, pre-galvanized steel (to BS EN 10346) can be an attractive, bright material which is suitable for non-arduous environments.

Pre-galvanized (or mill galvanized) steel is produced by unwinding steel coil and passing it continuously through a bath of molten zinc and then past air jets to remove excess zinc from the surface. The process is closely controlled to produce a thin, even and ripple free zinc coating with very few imperfections. Because this pre-galvanized steel coil must then be cut to shape during subsequent manufacture of support equipment, the edges of the finished components will have no zinc coating. This aspect, together with the relatively light zinc coating provided by the process, make pre-galvanized service supports suitable for indoor, low-corrosive environments (particularly where an aesthetically attractive appearance is important) but unsuitable for humid indoor or outdoor applications. 

Pre-Galvanized steel is produced by coating coils of sheet steel with zinc by continuously rolling the material through molten zinc at the mills. This is also known as mill galvanized or hot dip mill galvanized. These coils are then slit to size and fabricated by roll forming, shearing, punching, or forming to produce our pre-galvanized cable tray products.
