Six questions and six answers about galvanized aluminum magnesium steel plate. Now, Meitu Steel will introduce to you
what zinc aluminum magnesium steel plate is, as well as the precautions and quality objections during the processing.
Q:
What is galvanized aluminum magnesium steel plate?
A:
Galvanized aluminum magnesium steel plate is a new type of highly corrosion-resistant coated steel plate, with zinc as the
main component of the coating, consisting of zinc plus 1.5% -11% aluminum, 1.5% -3% magnesium, and trace amounts of
silicon (with slightly different proportions from different manufacturers). Currently, the thickness range that can be produced
domestically is 0.4-2.5mm, and our company can provide a thickness range of 0.4mm -4.0mm and a width range of 580mm
-1500mm.
Due to the composite effect of these added elements, their corrosion inhibition effect is further improved. In addition, it has
excellent processing performance under harsh conditions (such as stretching, stamping, bending, painting, welding, etc.), high
coating hardness, and excellent damage resistance. Compared with ordinary galvanized and aluminum zinc coated products,
it has better corrosion resistance. Due to its super strong corrosion resistance, it can be used instead of stainless steel or
aluminum in some fields. The corrosion resistance and self-healing effect of the cutting end face is a major feature of the product.
Q:
What are the uses of galvanized aluminum magnesium steel plate?
A:
Zinc aluminum magnesium products have a wide range of applications, mainly used in civil engineering and construction
(keel ceilings, porous panels, cable trays), agriculture and animal husbandry (steel structures and steel components for
agricultural greenhouses, greenhouses, and breeding equipment), railway roads, power communication (transmission and
distribution high and low voltage switchgear, box type substation exteriors), photovoltaic brackets, automotive motors, industrial
refrigeration (cooling towers, large outdoor industrial air conditioners), and other industries, with a very wide range of applications.
Q:
Why do there occasionally appear black spots on the surface of zinc aluminum magnesium steel plates?
A:
Zinc aluminum magnesium, due to its ternary alloy and active magnesium ions, commonly has black spots on the surface of
zinc aluminum magnesium products, which is objectively present and unforeseeable.
1. Mass production can relatively avoid black spot problems.
2. In the process of small-scale production, it will be relatively obvious, mainly because the alloy zinc ingot is not given sufficient
time to react during the heating process.
3. Currently, both domestic and international galvanized aluminum magnesium products have this problem, and whether the
black spots are obvious is directly related to the comparison of panel brightness among various manufacturers.
Q:
What issues should I pay attention to when purchasing as a user?
A:
Zinc, aluminum, and magnesium products have a wide range of uses, with different ordering standards for different applications,
such as: ① passivation+oil coating, ② non passivation+oil coating, ③ passivation+non oil coating, ④ non passivation+non oil
coating, ⑤ fingerprint resistance. Therefore, in the process of small batch procurement and use, it is necessary to confirm the
usage scenario and surface delivery requirements with the supplier to avoid subsequent processing problems.
Q:
Why is there a difference in surface brightness between the newly purchased galvanized aluminum magnesium steel plate and
the previous inventory?
A:
Zinc aluminum magnesium production steel plants are also adjusting brightness according to user needs. The color of the
board surface may change from dark to bright, and from bright to dark. Therefore, there may be slight color deviations among
different manufacturers and batches.
Q:
Is the ratio of high aluminum and high magnesium necessarily the best?
A:
High magnesium, high aluminum, brittle coating, relatively good corrosion resistance, salt spray test can reach 4000 hours,
but cracks may appear under the microscope after bending, suitable for flat plate use; If bending, stamping and other processing
are carried out during use, it is recommended to choose low aluminum and low magnesium solutions because the coating is
more flexible and the salt spray test can reach 3300 hours, making it the most cost-effective product in the current market.
