Have you ever heard of the galvanized steel sheet? If the answer is negative, we advise you to continue reading, as we will tell you the most important thing from scratch. If it is positive, we also encourage you to stay in this article, as we will present an interesting comparison with other types of sheet metal.

After all, we are professionals in this sector, so we know it in detail. Furthermore, we have stock permanent bases, something very convenient, especially in the shortage times that we are living. Let's go there!

What is galvanized steel sheet?

Galvanized sheet is a steel sheet that has received a specific treatment consisting of hot galvanizing. As such, The steel is immersed in a zinc crucible, so that the sheets are fully covered with this metal.

Sometimes, depending on the specific sheet, the immersion may have been carried out in a zinc-iron alloy. In any case, when carried out hot, it fully adheres to the steel, so steel and bath become inseparable. This is especially the case in the case of the zinc-iron alloy, which prevents chipping to a greater extent.

Therefore, it presents an inner sheet of steel that constitutes the thickness of the sheet, but also a zinc coating which gives it that characteristic galvanization. Thus, the steel is fully protected from contact with external and atmospheric agents.

In any case, it has the same capacity to be cut, drilled and punched as any other type of steel sheet. The main difference is the presence of a new metal layer that acts as a protector for the steel body.

The defining characteristics of this type of sheet metal

From what was said in the previous section, many characteristics of the veneer galvanized steel. However, as a clearer and more schematic presentation, we can talk about the following.

  • It is not a sheet made exclusively of steel. Although most of its mass is made of steel, the outer layer is made of other metals. Typically, this is zinc (Z) and, in some cases, a zinc-iron alloy (ZF).
  • It presents great flexibility in terms of its applications. This is because it allows cutting, drilling, profiling, etc. In fact, we we cut, fold and punch to size.
  • In order to guarantee its quality, functionality and durability, it is strictly regulated by European standards. The EN 10346 standard establishes guidelines regarding the thickness of the protective layer, the greater or lesser purity of zinc and the galvanization process.

The main advantages of its use

What is really sought with the galvanization of steel? There is no better way to answer this question than by presenting the advantages of this type of sheet, which derive from its coating.

  • Excellent corrosion protection. This allows its use in industries where it is treated with chemicals or harmful products.
  • Hermetic separation against external atmospheric agents. Therefore, it can remain outdoors for a long time.
  • Greater durability and resistance of the sheet. In this way, investing in it always ends up being profitable through amortization.
  • Increase in hardness. Prevents impact chipping and chipping.
  • Aesthetic appearance and regular appearance. In this way, they do not require too many subsequent finishes after installation.

The main uses of galvanized steel sheet

This type of steel sheet has an almost unlimited number of applications. However, we can highlight the following.

  • In the construction. Especially for the production of light metal structures and thermal insulation. Also for structural elements of medium and low height construction, entrance doors and elevators. Likewise, its use can be found in the manufacture of reinforcement profiles for plastic doors and PVC windows and for European-type fixings for plates made of different materials such as plaster.
  • In the automotive sector. Especially to manufacture internal and external body parts. Likewise, it allows the exterior parts of public transport such as buses and trams to be repaired easily and quickly.
  • In the mechanical industry and in machinery manufacturing. This must be understood in a broad sense. It includes the manufacturing of electrical equipment boxes, household appliances, mechanical equipment, packaging and measuring devices, etc.
  • In the manufacture of articles intended for domestic use.​ From tableware to tanks, through containers of all kinds, buckets and baths. Its uses in this area are practically unlimited.

What other types of sheets exist and how do they differ from galvanized steel?

Once you know galvanized steel sheets in depth, it is now convenient to distinguish them from other types of sheet.

  • Carbon-manganese structural steels. It has balanced characteristics, with minimum levels of elastic limit and tensile strength. It has acceptable ductility and ease of welding and good toughness properties.
  • Steel sheets with oxidation. Rusting of steel is voluntarily caused for decorative purposes. In this sense, it completely lacks the external protection that galvanizing offers.
  • Laser badges. They stand out especially for their excellent weldability. They have great resistance to fatigue and toughness.
  • Hot rolled and pickled sheets. They do not have any particular exterior protection, so they can rust more easily. They can be protected, at least temporarily, with oil.
  • Cold rolled and polished sheets. They have a greater ductile and cold handling capacity, making it easy to deform them to taste. In return, they sacrifice some stamina.

In conclusion, you have already seen what exactly the galvanized steel sheet. Likewise, you have read about its main uses, characteristics and advantages. The comparison with other types of sheet metal has also been very relevant, by the way. Now it's your turn to take advantage of all this information to your advantage.
