We have also talked a lot about the content of ppgi ppgl steel coil. I haven't told you about the process and use of ppgi ppgl steel coil. Today, Zuoze Special steel will show you.

1. The craft of ppgi ppgl steel coil

PPGI ppgl steel coil are made of cold-rolled steel sheets and galvanized steel sheets as substrates, which are coated with paint (roller coating method) in a continuous manner after surface pretreatment, and then baked and cooled. The main production processes of the common process flow are: uncoiling-pretreatment-coating-baking-post-treatment-coiling.

2. Product use:

PPGI ppgl steel coil has light weight, beautiful appearance, good corrosion resistance, and can be processed directly. PPGI ppgl steel coil provides a new type of raw material for construction, shipbuilding, vehicle manufacturing, furniture, and electrical industries. It has good effects on energy and pollution prevention. ( For more uses of prepainted steel coils, please refer to this article: Introduction to the application of ppgi steel coils)

The ppgi ppgl steel coil using galvanized steel sheet as the base plate has an organic coating on the zinc layer outside the zinc protection, which acts as a cover and isolation, which can prevent the steel sheet from rusting and can last longer than the galvanized steel sheet.

However, in different areas and different parts of use, ppgi ppgl steel coil with the same amount of galvanization, the same coating, and the same coating thickness are used, and the use time will be very different. For example, in industrial areas or coastal areas, the corrosion rate is accelerated due to the effect of sulfur dioxide gas or salt in the air, and the use time is affected. In the rainy season, the coating will be corroded faster if it is wetted by rain for a long time or where the temperature difference between day and night is too large, and the service life will be reduced.

The above is the whole content. Buildings or workshops made of ppgi ppgl steel coil have a long service life when they are often washed by rain, otherwise they will be affected by sulfur dioxide gas, salt and dust. Therefore, in the design, the greater the slope of the roof, the less likely it is to accumulate dust and other dirt and the longer it will be used; the area or parts that are not frequently washed by rain should be washed regularly with water.
