Article 24:How Do I Choose the Right PPGI Steel Coil?

PPGI Steel Coil is a kind of colour coated steel coil (PPGI coil). It uses galvanised steel as the base metal. The zinc layer is highly resistant to corrosion. Together with the coating, it is more durable than galvanised steel. The metal coated steel then undergoes several cleaning procedures, pre-treatment solutions, and finally a multi-layer organic coating including laminates, vinyl dispersions and paint. This continuous technique of applying different coatings is known as coil coating. As a result, the steel coil is used in the finished product without the need for painting or finishing.

PrePainted Galvanized Steel Coil (PPGI) and Pre-Painted Galvalume Steel Coil (PPGL) is a kind of building materials, with galvanized sheet and aluzinc sheet as the substrate, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then firing and cooling, finally the palte steel is called pre-painted (PPGI) or pre-painted galvalume steel coil(PPGL).

Galvanised steel coils are used in a wide range of different areas and applications. You can find it in metal roofing panels, microwave ovens, automotive trim panels, telecoms cables and much more.

It is also used in construction, home appliances, transportation, windows, doors, refrigerators and so on. It can also be further processed for other use as colour coated coil/sheet substrate, steel strip substrate and so on.

Benefits of galvanised steel coils

1. Cost

Firstly, the overall cost of galvanising is low compared to other coatings. In addition, galvanised steel coils are ready for use on delivery. It does not require additional surface preparation, inspection, painting or coating.

2. Durability and reliability

Galvanised steel is usually made from hot-rolled or cold-rolled steel coils as a base material. The steel is strong and the galvanised coating is robust and durable.

3. Corrosion and rust protection

The main benefit of galvanised steel coil is its corrosion and rust protection properties. The iron in steel is a highly reactive chemical that tends to rust. However, the addition of zinc acts as a protective buffer between the steel and moisture or oxygen. The zinc coating thus acts as a barrier against external attack and will sacrifice itself to protect the steel beneath.

4. Life expectancy

After galvanising, GI coils have a life expectancy in the working environment of well over 50 years, and can last for over 20 years in severe water exposure situations.

5. Full protection

every inch of the galvanised steel coil is protected against damage, including grooves, sharp edges and hard-to-reach areas.

6. Easy to inspect

The product’s simple construction design makes it easy to assess with the naked eye and allows for simple non-destructive thickness measurement methods.

How do I choose the right PPGI steel coil?

With its excellent properties, PPGI steel is widely used in construction, household appliances and light industry. Due to its different applications and environments, special attention should be paid to the selection of the right PPGI steel coils. the sales staff of Jianhui Steel Supply, with their professional knowledge and experience in communicating with customers, summarise four aspects.

1. Coating hardness: Coating hardness refers to the ability of the plating to resist scratch, friction, crash or other mechanical action, and PPGI steel coil scratch resistance, wear resistance is closely related. Mainly through the use, processing methods, storage conditions and other options.

2. Coating thickness: The thickness has intimate connection with the corrosion resistance of ppgi steel coil, and the corrosion resistance usually improve with the increase of coating thickness. The coating thickness should be confirmed by the environmental corrosiveness, service life and durability.

3. Coating colour difference: There will possibly to occur color difference during the produce and use process of the ppgi steel coil. The color difference is influenced by the production organization, color, use time, use environment and other factors.

4. Coating gloss: Gloss mainly choose based on the use and use habits. For example, the building-use ppgi steel coil always choose middle or low gloss, and household appliance ppgi steel coil always choose high gloss.

5. Coating gloss: gloss is mainly based on the use and use habits to choose. For example, PPGI steel coils for construction are always selected for medium or low gloss, and PPGI steel coils for household appliances are always selected for high gloss.

A Comprehensive Guide to Galvanized Steel Coil ...

Introduction:

In the world of steel manufacturing, three prominent types of steel coils have gained widespread popularity due to their versatile applications and outstanding properties. This article will delve into the characteristics, manufacturing processes, and diverse applications of Galvanized Steel Coil, Galvalume Steel Coil, and Prepainted Steel Coil.


Galvanized steel coil is a product that has undergone a galvanization process to protect it from corrosion. This process involves coating the steel with a layer of zinc, which creates a barrier against moisture and other corrosive elements. The galvanization process enhances the steel's durability, making it ideal for outdoor applications and industries such as construction, automotive, and agriculture.


Galvalume steel coil is another corrosion-resistant option, but it differs from galvanized steel as it combines aluminum and zinc coatings. This unique combination provides superior protection against rust and oxidation. Galvalume steel coil is renowned for its excellent heat resistance and long lifespan, making it suitable for roofing, cladding, and other architectural applications.


Prepainted steel coil, as the name suggests, is a type of steel coil that comes pre-coated with a layer of paint or other coatings. 

This pre-treatment not only adds an attractive finish to the steel surface but also provides additional protection against environmental elements. Prepainted steel coil finds extensive use in the manufacturing of appliances, transportation equipment, and building components.


Manufacturing Processes:


  • Galvanized Steel Coil: The galvanization process involves immersing the steel coil in a bath of molten zinc, followed by a series of annealing and cooling steps. This results in the formation of a zinc-steel alloy coating on the surface.
  • Galvalume Steel Coil: The manufacturing process of Galvalume steel coil employs a continuous hot-dip method, where the steel is coated with an aluminum-zinc alloy.
  • Prepainted Steel Coil: To produce prepainted steel coil, the manufacturers apply primer and then a topcoat of paint or resin through the coil-coating process. This process ensures an even, durable, and attractive finish.

Applications:


  • Galvanized Steel Coil: Galvanized steel coil is commonly used for making corrugated roofing sheets, guttering, fencing, and structural components in construction.
  • Galvalume Steel Coil: Galvalume steel coil is widely used in architectural panels, standing seam roofs, and industrial siding due to its excellent corrosion resistance.
  • Prepainted Steel Coil: Prepainted steel coil adds aesthetic appeal to appliances, garage doors, cladding, and various building components while providing weather resistance.

Conclusion:

Their excellent corrosion resistance, longevity, and aesthetic appeal make them valuable assets in various industries. As technology continues to advance, these steel coils will likely see further advancements, cementing their position as essential materials in the modern world.
