In the market, there have many classifications of the sheet steel coil. Today our article will introduce the sheet steel coil to you by the classification of surface features. If you have been in the industry of steel products for many years, you may know that there have a kind of sheet steel coil with a protective layer. All of these sheet steel coils which have protective layer are called the coated steel coils. If you want know more about the coated steel coils, you can continue to read.
There have many kinds of the coated steel coils, such as the galvanized sheet coil, Tin-plated sheet coil and composite steel sheet coil. But there has another kind of sheet steel coil which has other layers on the galvanized. Its name is ppgi galvanized steel coil. Let us to know the complex ppgi galvanized steel coil deeply.
The composite of the ppgi galvanized steel coil
Usually, the ppgi galvanized steel coil include many layers. The first layer is based plate. It always uses the galvanized steel to do the based late. But you know why the producers do not choose others sheet to do the base metal. That for the galvanized steel is regular steel that has a zinc layer. Because the zinc layer, the kind of sheet steel which has zinc layer can provide corrosion resistance to the steel substrate.
The second layer is primer coat on the zinc layer. In the process of the production, the machine will apply a primer coat on top of the galvanized layer. We all know that most of the sheet steel have a smooth surface, and it is difficult to keep the paint layers well. Then the primer coat can help us solve the problem for us. The primer coat can enhance the adhesion of the subsequent to the steel surface. In addition, it helps us to ensure that the paint adheres well and provides long-lasting protection.
And the third layer is paint coating. This layer is why the ppgi galvanized steel coil could have many kinds of colors. We can paint this layer by any color accord the demand of customers. in addition, we can also accord to specific requirements to change the finish, and performance characteristics of the sheet coil. Of course, in this step we can paint one or more layers of paint by our need. Except making our sheet coil be more beautiful, this layer can also enhance the protective properties of the coil.
The fourth layer is top coat. We could paint a clear top coat over the paint layers to provide additional protection and durability. The top coat can enhance the resistance to UV radiation, scratches, and abrasion, further extending the lifespan of the PPGI galvanized steel coil. We can decide if we need this layer accord our need.
And we need to know that there not has a specific regulation of these layers. The specific composition and thickness of each layer may vary depending on the manufacturer and the intended application of the PPGI galvanized steel coil.
Some applications of the ppgi galvanized steel coil
- Construction: the PPGI sheet steel coils have a widely usage in the construction industry of roofing, siding, and structural components. The colorful surface is the reason why it can suit the construction well.
- Automotive: PPGI galvanized steel can be used in automotive manufacturing for body panels, chassis components, and other structural parts. For many times, the car need to drive in various bad environment, that it is important for the components to have well corrosion resistance and paint adhesion properties. The PPGI galvanized steel can satisfy the demand well.
- Furniture: PPGI coils can play a role in the production of furniture. Usually, it be lover foe the manufacturers who make the cabinets, shelves, and other fixtures.
- Containers and Packaging: PPGI steel coils are usually used to manufacture containers and packaging materials for various industries.
- Electrical Enclosures: whether you know that the PPGI galvanized steel has a good corrosion resistance and mechanical strength. Dut to these features, it can play an important role in the fabrication of electrical enclosures and cabinets.
- Signage and Displays: PPGI coils can suit the signage industry for outdoor and indoor signage applications well
- Household Goods: PPGI galvanized steel can be produced various household goods such as gutters, downspouts, and HVAC ductwork.
Our company also is one of the leading China pipe manufacturers, we can provide the high-quality sheet steel coil and the sheet pipes by a lower price compared with the oversea manufacturers.
