How to Calculate Weight of PPGI Sheet?

The PPGI sheet size can be customized according to your needs. And according to the size, you can calculate its weight roughly. Let’s review the 0.5 mm PPGI profile sheet weight.

How to Calculate Weight of PPGI Sheet

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.

For example, if your PPGI sheets are 0.5 mm in thickness, the PPGI sheet weight per sqm is about 3.925 kg. 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). If you order 5,000 pieces, the total weight is about 40 tons. Then it requires two 40GP containers for shipping.

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 the PPGI color coated sheet is only 6-14 kg/m2, which is about 1/30 of a brick wall. 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 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 deep foundation, which is good for the environment.

What Is PPGI Sheet?

PPGI sheet is short for pre painted galvanized steel sheet. It is also known as pre-coated steel sheet or color coated steel sheet, which is a product made of hot-dip galvanized steel sheet or electro-galvanized steel sheet. After surface pretreatment (degreasing and cleaning), one or several layers of organic coatings are painted and then baked and solidified continuously. Then the coils will be cut into sheets in desired size. The corrugated PPGI sheets is profiled with rolling machine.

PPGI Sheet Manufacturing Process

The common PPGI steel production method is double-coating and twice-baking in coils. The PPGI steel sheet is a product of PPGI coils. Let’s review the process steps by steps.

PPGI Manufacturing Process

PPGI Coil Manufacturing Process

1. Uncoil and weld the zinc coated steel coils. The coils will go through inlet looper for pretreatment continuously.

2. Pretreatment to remove the rust and impurities through degreasing, cleaning and chemical conversion.

3. Primer Coating. Both sides will be coated for the first time, and then dry the coating.

4. Finish Coating. After cooling down, the coils will be painted again, and then be dried again.

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

This is the whole process of making color coated steel sheets. It is a continuous process, which can reduce color differences and surface defects.

PPGI Structure

As mentioned, PPGI 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 PPGI 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.
