How to Calculate Weight of PPGI Sheet?

You can estimate the weight of your PPGI sheets with the following formula:

Thickness (mm) * Width (m) * Length (m) * 7.85 = (kg/pcs)

Note: 7.85 is the density of iron. It means per cubic meter of iron weighs 7.85 tons.

Actually, the weight per sqm mainly depends on the thickness. For example, if your GI colour coated sheets are gauge 28 (0.38 mm) in thickness, the PPGI sheet weight per sqm is about 2.98 kg. If the thickness is gauge 24 (about 0.61 mm), the weight per square meter is about 4.79 kg.

 

Weight of PPGI Profile Sheet

Weight of PPGI Profile Sheet

Below let’s calculate the weight of the 0.5 mm pre-painted galvanized profile sheet. If it is 1.15 m in overall width, 1.8 m in length, the weight of each piece is about 8.12 kg (0.5*1.15*1.8*7.85). So there are about 123 pieces per ton. If you order 5,000 pieces, the total weight is about 40 tons. Then it requires two 40GP containers for shipping. If you want more details, please contact us!

Pre-painted Galvanized Steel Sheet Price

The wholesale pre-painted galvanized sheet price is about 800 to 1,200 USD dollars per ton. It is different with many factors, such as the painting, paint thickness, etc. For example, painted steel whiteboard (writing board) will be more expensive than the common white PPGI sheets because of the different paints. Also, some PPGI sheets use different paints for the top and back sides. Besides, the PPGI sheet price will change with the market. Moreover, the quantity will also largely affect the price. As a manufacturer of precoated galvanised iron profile and plain sheets, we have a PPGI factory in Shandong Province. So we will offer a factory-direct sale price. Also, we will offer discounts for bulk orders. Welcome to contact us for more details!

Advantages of PPGI Color Coated Sheet

The GI colour coated sheet we produce has characteristics of long service life, easy installation, high strength, and beautiful appearance. That’s why it is getting popular among investors.

1. Light Weight

The weight of coloured GI sheets ranges from 1 to 10 kg/m2, which is about 1/30 of a brick wall. According to the weight calculation formula: Thickness (mm) * 1 m * 1 m* 7.85 = (kg/m2), the PPGI sheet weight per sqm mainly depends on the thickness. Therefore, the weight of our GI color coated sheet is available from 1.099 kg/m2 (0.14*1*1*7.85) to 9.42 kg /m2 (0.14*1*1*7.85). So its shockproof performance is better, which makes the building safer. Besides, it is easy to transport to save your cost.

2. High Strength

Colour coated GI sheet keeps the mechanical properties of steel, including bending strength, elongation, tensile strength, etc. It is still tough and durable to use. The application of the coating is to protect its surface from rusting and make it good-looking.

3. Beautiful Appearance

The colour coated steel sheet is pretty, which means there is no need for extra decoration. Moreover, the color can keep for many years.

4. Flexible and Quick Installation

It is fast and easy to install if using colored galvanized sheets as building materials. On the one hand, it can shorten the construction period by more than 40%. On the other hand, there is no need for a deep foundation, which is good for the environment.

What Is PPGI Sheet?

PPGI sheet is short for pre painted galvanized steel sheet. It is a kind of pre-painted steel sheet, which uses galvanized steel sheet as the base metal. Then it is painted with one or several layers of organic coatings after surface pretreatment (degreasing and cleaning), and then baked and solidified continuously. Then the coils will be cut into sheets of the desired size. Through rolling equipment, the plain sheets can be profiled into corrugated PPGI sheets.

PPGI Sheet Manufacturing Process

At Wanzhi Steel, we commonly use the double-coating and twice-baking method. If you have special requirements, please let us know. Let’s review the process step by step.

PPGI Manufacturing Process

PPGI Coil Manufacturing Process

1. Uncoil and weld the zinc-coated steel coils so that they can be processed continuously.

2. Then the coils will go through an inlet looper for pretreatment to remove the rust and impurities through degreasing, cleaning, and chemical conversion.

3. Primer coating process. Both sides will be coated and baked for the first time.

4. Finish coating process. After cooling down, the coils will be painted and dried again.

5. Cooling down the coils below 40 °C. After the quality control system, the coils will be rolled up through an outlet looper. Then you can shear or profile the coil into sheets according to your needs.

Here is a video showing how to cut PPGI coil into plain sheets.

Below is a video showing the profiling process of corrugated sheets.

PPGI Structure

As mentioned, pre painted galvanized steel sheet uses zinc coated steel as substrate. That is to say, it is made of base metal and zinc coatings. Before coating, it will be cleaned to remove the rust and impurities on the surface. Then it will be coated by a chemical conversion coating. Then several layers of organic coatings are painted. Taking double-side and twice-baked pre painted GI sheets for example, it contains base metal, zinc coating, pre-treatment (chemical conversion coating), primer coating, and top/back coating. Below is the structure diagram of the PPGI color coating sheet.

PPGI Color Coated Sheet

Pre-painted Galvanized Steel Sheet Structure

PPGI Sheet (Hot-dip galvanized)

The product uses a hot-dip galvanized steel sheet as the base metal. In addition to the protection of zinc layer, the organic coating also protects the metal from rust. So its service life is longer than that of the hot-dip galvanized sheet. The zinc thickness of the hot-dip galvanized substrate for exterior uses can reach up to 275 g/m2. We offer custom solutions to meet special requirements.

PPGI Sheet (Electro-galvanized)

The electro-galvanized sheet is used as the substrate and then be painted with organic coatings. Because the zinc layer of the electro-galvanized sheet is thin. So this product is not suitable for outdoor uses, such as walls, roofs, etc. But because of its beautiful appearance and excellent processing performance, it can be mainly used in home appliances, audio, steel furniture, interior decoration, etc. You can choose according to your use purpose and environment.

PPGI Sheet Package

Firstly, PPGI panels are strapped together with at least two steel belts in both transverse and longitudinal directions. Then wrap the package with waterproof kraft paper and plastic film to protect it from moisture. According to your request, it will be fixed with wood or galvanized pallet. Below are some pictures for your reference.
