What is a PPGI Coil?

PPGI Coil is an abbreviated form of Pre-Painted Galvalume Coils. In simpler terms, this coil is a pre-coated steel coil.

Its coil structure is made by passing through a coating process to a sheet of hot galvanized steel, aluminum, cooking, and seasoning it.

Different numbers of organic paint coating layers are done on it before going through the manufacturing process.

PPGI Coil is an advanced coating technique that ensures to adhere coating firmly with metal base and doesn’t let it peel down even in the bending, rolling, or other processes.

The PPGI Plain Sheet that is produced using this method is a pre-painted material. PPGI Coil as the substrate uses galvanized steel.

What is the Process of Manufacturing a PPGI Coil?

The process of manufacturing PPGI Coil starts by cleaning galvanized steel. After that, it is preheated, and in the last, its painting is done in the form of a coil.

Let’s take a closer look at the step-by-step process of manufacturing.

1. Firstly, the substrate of a coated coil has to be uncoiled, welded and after welding, it has to pass the process of cleanliness by the loopers, and after it, the time of preheating comes.
2. After the above procedure, its surface has to be coated in layers by chemical conversions.
3. Now you have to do twice the painting and drying on the above steel side. It might also possible that in some cases, you have to do this three times.
4. In the second last step, cool down the steel.
5. PPGI Coil will be ready to go for sales after passing the tests.

What are the Characteristics of a PPGI Coil?

These are the following characteristics of PPGI Coil:

• The coating of chemical conversions done on the PPGI Plain Sheet protects the coil from rusting and makes it corrosion-resistant.

• PPGI Coil is made light-weighted, which makes it easy to travel around with you wherever you go.

• This color-coated coil has excellent durability and long life compared to the galvanized steel sheets, and it also has heat resistivity. At the same time, galvanized steel sheets are much more complicated to change their color, especially at high temperatures. Its welding function is also great, along with the spraying and processing functions.

What are the Standard Specifications of the PPGI Coil?

Substrate:

The substrate can be done using many different steel sheets having metallic coating depending on the customer’s requirements.

Coating Systems:

This specification depends upon a primary coating covered with different layers of thickness and types of coating on top.

This combination of primary coating and top coating system is classified into two groups such as:

• Two-coat thin-film system

• Two-coat thick-film system (or more than two)

The most common materials used in top coating are fluoropolymer, silicone polyester, plastisol, acrylic, or polyurethane.

Steel Sheet Metallic Coating:

Metallic coating of steel sheets is usually done by using a hot-dip method, while the coating of the coil is by using organic films, which are perfect for those exteriors manufactured to utilize in the exposed products of buildings.

What Kind of Material is used in the coating of a PPGI Coil?

PPGI Plain Sheet is mainly covered with layers of zinc. Zinc coating is used to increase the longevity of the coil because metal blending always has been doing a great job in fighting all the weather conditions and ideally replacing the needs of using wood.

99% of the PPGI Coil coating is done by using zinc, and it is leaf-free metal. Which is when smoothed turned into a zinc spangle that leaves a great impression on the visual appearance.

The corrosion resistance and the zinc coating are directly proportional to the thick layer of coating. The Z600 coating or 42 µm on both sides usually has a service life lasting up to 80 years.

Zinc can produce zinc carbonate by reacting with oxygen in the exposure of atmosphere and after that by reacting with carbon dioxide. Zinc carbonate works to stop corrosion and protect the coil from other things.

What is the Process of Zinc Coating of PPGI Coil?

Processing of PPGI Coil is done in four basic steps including:

Forming:

The zinc coating can withstand extreme distortion because of its flexibility and superior frictional behavior. As a result, the same forming techniques for bare steels can generally be utilized for zinc coating metals without significant changes to the processing conditions.

Slight variances in surface behavior may need adjustments for lubricant. The metal coating benefits from acting as a lubricant, which is especially useful when shaping at low and moderate surface pressures.

Welding

Metal-coated steels could be welded using various processes, such as resistance, laser, and arc welding. The measurements of the joints that are welded are likely to non-coated steels.

The most frequently utilized welding processes, such as spot welding, produce outstanding results with metal-coated steels. The zinc-based coating’s strong anti-corrosion qualities are primarily retained in the space of a well-made spot weld.

Due to the reduced resistivity of the coating, spot welding of metal-coated materials requires somewhat more current and electrode force than spot welding of bare steels. Similarly, increasing the coating thickness raises the needed welding margin.

Joining

All coatings that are based on zinc are perfect for bonding adhesives depending on the length of the surface and adhesive such as epoxy, acrylic, or polyurethane adhesive are compatible. One benefit of this bonding is that the coating’s anti-corrosion capabilities are preserved as this coating is essentially intact in the joint area.

Any oils or contaminants on the surfaces to be adhesively joined should be adequately cleaned to guarantee excellent adherence. The surface’s compatibility with the glue should always be addressed on a case-by-case basis.

Painting

Painting gives the finished product the required color and increases the corrosion resistance of the result. Usually, quality B is recommended to pass through the son, and for that, some particular surface of the paint is needed.

When the surface is adequately equipped, and the appropriate pigments are utilized, zinc coating offers a good platform for painting.

What Type of Paint Material is Used in PPGI Coil Coating?

Commonly the coating of paint used in the making of PPGI Coil is polyester to make it free from corrosion. The layer of the back of the PPGI Coil strip is done by using polyurethane, which can epoxy to prevent the coil even if it works as an insulator in making a sandwich panel.

There are four topcoats of polyester including:

R.M.P or Regular Modified Polyester

The most extensively used coil coating containing lasting Polyester paint and heat dried is regularly modified polyester. It’s used on interior/exterior materials that don’t have a lot of heavy drawings. Its commercial feasibility is due to its changing colors and glosses.

RMP is utilized for non-processing exterior panels and interiors. It is commonly superior in terms of workability, durability, and weather resistance and is used for various tasks. The top finish can be given a matte or wrinkled appearance.

Uses

• Building Interior/Exterior

• Sandwich panels

• Steel furniture

• Roof, Gutter

S.M.P or Silicone Modified Polyester

Silicone Modified Polyester is a heat-dried silicone epoxy modified polyester paint. Because it is more durable than regular polyester, it is commonly used in the construction process. In the case of seaside or industrial zones, SMP ensures economic benefits. A limited guarantee of 10-15 years is provided.

Paint containing silicon epoxy is applied to SMP items and baked. Because of its exceptional weather resistance, it is ideal for coastal areas.

Uses

• Construction material

• Sandwich panel etc.

H.D.P or High Durable Polyester

Similar to PVDF in terms of durability, but at a lower cost and with the added benefit of a broader variety of gloss and color levels. A limited guarantee of 10-15 years is provided. It can be coated in a variety of patterns, depending on the needs of the buyer.

Uses

• Industrial Building

• Roof etc.

P.V.D.F or Poly vinylidene Fluoride / PVF2

PVF2 coil coating provides excellent weatherproofing, durability, wear resistance, and hardness. PVDF may be painted in a simple mono color type and many pattern types using its unique painting methodology.

PVDF coating forms fluorine carbon resin, pigment, and ester solvent and solidifies to a dry film with excellent weather resistance following high-temperature baking and cooking. The hydrophilic surface treatment prevents dust from adhering to the surface and allows for easy dust removal.

Uses:

• Defense Industry

• Medical industry

The color of the paint can be customized according to the samples given by customers. It’s a perfect combination of paint and galvanized steel to increase the durability of the PPGI Coil.

• Protects the metal from several weather conditions.

What is the Importance of the Inner Quality of the PPGI Coil?

The inside quality of the PPGI Coil is as essential as its outer sides. Its sound quality directly depends on the three primary factors, including the coating substrate’s benefits, the coating’s thickness, and the manufacturing process.

It proves the importance of the Inner quality of PPGI Coil and the importance of different kinds of cladding material and coating substrate.

What is the Reason Behind the Popularity of PPGI Coil Among Other Different Building Materials?

There are three main reasons behind the popularity of PPGI Coil, which makes it stand out. Such as:

• Its weight is way lighter than the brick wall that is used in the construction of houses. The importance of a PPGI Coil is just 1/30 to the weight of that brick.

• Its strength is a perfect replacement for the beam column used in the past for doing building projects. If the PPGI Coil were introduced at that time, it would be convenient for them.

• Its easy-to-operate features, as well as flexibility, are its significant benefits.

• It’s a saying that whenever you start using new products, it takes time to get used to them, but it’s not the case with PPGI Coil as it makes the period of construction shorter and makes the working more accessible.

Which System Provides the Corrosion Protection in Making of PPGI Coil?

The duplex system is responsible for protecting the coil from corrosion. It is performed during the manufacturing process of the PPGI Coil when the painting is done after the hot dipping of galvanized steel.

This system provides the base of steel both types of barrier and catholic protection. The painting done through this process works as a barrier for protecting the galvanized coating and also plays an essential role in reducing the zinc corrosion rate.

Even in the worst atmosphere, this kind of protection system works very well and makes the product last for a longer time.

FAQs of PPGI Coil.

1. What is the Major Difference Between the PPGL and PPGI Coil?

An essential difference between the PPGL and PPGI Coil is the coating applied to both of them.

PPGI Coil or pre-painted galvanized steel coil coating is done by the even covering of a layer of zinc.

While PPGL or pre-painted galvalume steel coil coating is with a combination of aluminum, zinc, and other trace elements.

2.What are Color Galvanized Coils Used forPPGI Coil?

The color galvanized coil is used in PPGI Coilagainst the rust of the steel placed on the surface to increase its lifespan.

To prevent decay on the surface of the steel plate and prolong its service life. Galvanizing is a cheap but worthy anticorrosive method that is used commonly all over the world.

3. What is Pre-Painted Steel used in PPGI Coil?

Pre-paint steel is a substrate used in PPGI Coil that is done directly on the bare surface of the metal, and by using a continuous coating process, the paint is applied on both sides of the metal, which gives it an evenly finishing.

This process doesn’t affect metal at all, and it remains cleaned and unwounded.

4. What is Meant by a Coated Sheet on PPGI Coil?

At the coating units or the steel plants, the steel sheet is coated in the form of a coil before fabrication.

After the coating on PPGI Coil, the steel-coated sheet gets ready for fabrications and can be used without surface painting.

5. What is Meant by Coil Coating of PPGI Coil?

Coil coating is the continuous process of PPGI Coil that is used to coat metals before fabrications.

A coil coating process starts with an uncoiling process and then goes to an accumulator. After painting, it goes to the exit accumulator, and then winding is done on it using a recoiling process.

6. Is it Necessary to Paint Galvanized Steel in the manufacturing of PPGI Coil?

The truth is that galvanized steel will not take paint during the making process of PPGI Coil. The zinc layer left on the metal just after the galvanization process is intended to prevent corrosion and resists paint, leading it to flake or shed over time.

7. What is the Primary Use of Coil Coating of PPGI Coil?

Coil coating of PPGI Coil has been used for the manufacturing process is highly automated industries as it provides the metals an efficient coating.

What makes it efficient is its cutting and formation and cleaning, and pre-treatment makes it bound tightly and provides durability.

8. What is the Rate of Zinc Rusting in Water that is used in the Coating of PPGI Coil?

Zinc coating of PPGI Coilrusts in water, just like other metals, but its corrosion rate is 1/30 for steel.

Its corrosion rate may vary depending upon the environment in which you are using it.

9. Is it Appropriate to Use Rubbing Alcohol to Clean the Metal Before the Painting of PPGI Coil?

Metals don’t usually need to be prep before use, but you can do it using denatured alcohol if you still want it.

Using a wire brush for rubbing alcohol is the best combination if you want better results on your PPGI Coil, and using alcohol will be an excellent option for you are doing it indoors because it doesn’t produce any harsh smell.

10. What is the Process of Making Metal Coils that are converted later on into PPGI Coil?

By removing the rusting from the hot-rolled sheet using pickling process which is done by using the solution of a weak acid and then washing it after that has to be brushed, dried, oiled and in the last by unrolling a sheet and passing it through a mill to under pressure and then binding it into a roll.

That’s how a metal coil or cold-rolled sheet is made and then used in the making of PPGI Coil.

11. Why Only Zinc is Used Instead of Other Metals in Coating of PPGI Coil?
The galvanizing process only uses zinc and no other metals for coating in producing PPGI Coil because zinc can oxidize, and it also provides the steel with acid protection.

Whenever the steel coil has to face oxygen and acids, they will directly attack the zinc but not the steel.

12. What is the Lasting Period of Zinc Coating on PPGI Coil?

The zinc coating usually lasts for 35 to 70 years on PPGI Coil if used in the harshest soil. But if used in less harsh soil, it will last for more than 70 years.

It also depends upon the humidity, which has different effects on the corrosion even if the temperature doesn’t affect the zinc coating as it is manufactured to fight even with the worst weather conditions very well.

13. Which is the Best Way to Paint the Metal of PPGI Coil among Spray Paint and Brush Paint?

Applying paint to the metal of PPGI Coil with the brush is a better option.

Paint metal with oil-based paint available in the can if you want the paint to last for a longer time.

We know spray paint is an easier option to go with; however, spray paints usually don’t give a durable finish. It is easier to create a thick layer of a painting by using brush paint metal.

14. How to Identify if a Steel Coil is Cold Rolled in the making of PPGI Coil?

There are specific ways to identify the cold-rolled steel to make PPGI Coil such as they provide better and much more delicate surfaces having closer tolerances.

Surfaces are that much smooth that sometimes give the feel of oiliness. And It will provide your coil an excellent edge, and corners also will provide a perfect square.
