Difference between Pre Painted Galvanized Steel Coil and Pre Painted Galvanized Steel Coil

The difference between the same Pre Painted Galvanized Steel Coil is the quality and service life, and the key depends on the needs of customers. The seemingly same PPGI Steel Coil will have different qualities and service lives. The Color-coated Steel Coils that meet customer needs will be the best Color-coated Steel Coils. Our service is to provide customers with Pre Painted Galvanized Steel Coil with corresponding needs.
What are the differences between Pre Painted Galvanized Steel Coil with the same requirements? It lies in the quality of the substrate, the weight of the zinc coating, the brand and quality of the paint, and the most important point is whether the salesperson serving you can understand your real needs and meet your needs.

 

Test for PPGI/PPGL steel coil

The following are the various tests we perform during production. Please see the detailed introduction below

(Only the test of color-coated coils is introduced here. For detailed test of substrates, please see Galvanized Steel Coil and Aluzinc Steel Coil)

Thickness for paint coating

Paint thickness is a very important point, which is one of the factors that determine the service life of the product. Usually we use a Paint film instrument to measure it, which is the most commonly used detection method on the market. The Paint film instrument can basically accurately measure the thickness of the paint film.

Paint Brand

This is also one of the factors that determine the service life of the product. Most customers do not have too many requirements on the brand, because the brand represents quality as well as price. For customers, products with cost-effectiveness and that meet local market demand will be the most suitable products. Of course, some customers also have requirements for brands. For example, customers want Nippon, Aksu, and Winter (these are relatively large brands), and some specify other small brands.

T Bending Test

This test is to detect the flexibility of the paint. By bending, observe the cracking or shedding of the coating on the bent surface. Bending 180 degrees is 0T, and continuing to bend 180 degrees is 1T, and so on, 2T, 3T. Under normal circumstances, 2T-3T is the most perfect state. 0T paint does not fall off, which means that the paint is very soft, which is very good for make corrugated roofing sheets and will not fall off. However, if the paint is too soft, it will reduce the service life of the tiles when used on roofs or walls. 4T-5T does not fall off, which means that the paint is too hard, which is more friendly to the service life of the product during use, but it will not pass when produce Galvalume Roofing Sheet and the paint will fall off. The key point depends on the customer's use and what type of roof to produce. Different tile types have different requirements for T-bends. 

Wipe Test

This is a basic test. Normally, if the paint does not fall off after wiping it 100 times with cotton soaked in butanone, it meets the standard. If the paint falls off, it is most likely that the baking temperature is not enough and the paint is too wet.

Pencil Hardness test

Use pencils of different hardness (H 2H 3H) to scratch the steel plate at a 45-degree angle. If there is no cracking or scratching on the paint film, it meets the standard.

Gloss test

About transportation

 

Bulk Ships and containers are available, depending on customer needs. In the past two years, container shipping costs have risen sharply, and many customers choose bulk carriers instead of containers. However, some customers still choose containers for quickly delivery time and safety.
For large orders with large quantities, some customers will choose bulk carriers.

 

So choose the most suitable transportation method according to your own needs, and we will cooperate with you.
