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
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
Areas not normally coated during fabrication, such as cuts and
welds, are protected by neighboring zinc, which works as a
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
In accordance with A653/A653M-06a, pre-galvanized steel is not
generally recommended for outdoor use or in industrial
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.
