PPGI Color Coated Sheets

The substrate is the "body" or "skeleton" of the ppgi color coated sheets , which determines the most basic strength and quality of the material. The beautiful colored coating (paint) on the outside is just its' clothing '.

The most common color coated substrates on the market are mainly the following, each with different "physical fitness":

1. Cold rolled substrates with ppgi color coated sheets - "economical and practical"

·In layman's terms, it is the most ordinary steel figurine, without wearing any "underwear", directly wearing a "colored coat" on the outside.

·Advantages of cold-rolled substrates with ppgi color coated sheets : cheap.

·The disadvantage of cold-rolled substrates with ppgi color coated sheets is that they are very prone to rusting. Once the surface paint is scratched, the iron inside will quickly rust.

·Where is the cold-rolled substrate of ppgi color coated sheets used? The cold-rolled substrate of ppgi color coated sheets is mainly used indoors, in dry environments, or inside products that do not require high rust resistance, such as internal parts of some furniture and electrical appliances.

2. Hot dip galvanized substrate with ppgi color coated sheets - "Popular Star Type"

·Common understanding: A layer of zinc is hot-dip coated on the surface of ordinary steel. You can understand it as putting a silver rust proof underwear (zinc layer) on the iron frame first, and then wearing a beautiful "colored coat" outside.

·Advantages of hot-dip galvanized substrate with ppgi color coated sheets : greatly enhanced rust prevention ability. Zinc sacrifices itself to protect iron (this is called "cathodic protection"), and even if there are small scratches on the paint, the zinc layer can prevent the wound from spreading and rusting.

·Where to use hot-dip galvanized substrates with ppgi color coated sheets : This is the most commonly used and mainstream choice. Most factory roofs and walls are made of it, which has a very high cost performance ratio.

3. Aluminum zinc coated substrate with ppgi color coated sheets - "high-performance endurance type"

·Simply put, this is an upgraded version of galvanized substrate. Its coating is an alloy of aluminum, zinc, and silicon, making this' underwear 'more high-end.

·Advantages:

·The aluminum zinc coated substrate with ppgi color coated sheets has better corrosion resistance, which is 2-6 times stronger than the rust resistance of ordinary galvanizing.

·Advantages of aluminum zinc coated substrates with ppgi color coated sheets : better heat resistance due to the high composition of aluminum.

·The disadvantage of aluminum zinc coated substrates with ppgi color coated sheets is that they are slightly more expensive than those with hot-dip galvanizing.

·Where is the aluminum zinc coated substrate for ppgi color coated sheets used? It is used in higher demand situations, such as coastal areas (with high air salinity and strong corrosiveness), near chemical plants, or some high-end buildings.

4. Galvanized aluminum magnesium substrate with ppgi color coated sheets - "Top protection type"

·Simply put, this is the latest 'black technology' product. Aluminum, magnesium and other elements were added to the zinc solution to create a "super protective underwear".

·The advantages of galvanized aluminum magnesium substrate with ppgi color coated sheets are: extremely strong rust prevention ability, especially excellent protection for shear fractures (ordinary galvanized sheet cuts are prone to rusting, which is not the case). The service life is very long.

·The disadvantage of galvanized aluminum magnesium substrate with ppgi color coated sheets is that it is the most expensive.

·Where is the galvanized aluminum magnesium substrate ppgi color coated sheets used? It is used in fields that require extremely high lifespan and reliability, such as large public facilities, bridge maintenance structures, etc.

The substrate is the layer of metal core inside the ppgi color coated sheets , like the skeleton of a human body. The most common is galvanized, which has good rust prevention and is cost-effective; If you want something better, choose aluminum zinc plated ones; If it is by the seaside or has particularly high requirements, better galvanized aluminum magnesium substrates need to be used.
