Here is a video, which was taken at our factory. It shows the profiling process of PPGI sheets.

PPGI Roofing Sheet Weight

The weight of a roofing sheet can be calculated according to the following formula:

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

Please note that the width here refers to the overall width rather than the effective width.

Advantages of PPGI Roofing Sheet

Galvanized color-coated roofing sheet is widely used in commercial, agricultural, industrial, and civil buildings. It is because of its many benefits, such as:

1. Long Service Life

The color-coated GI roofing sheet uses zinc coated steel as substrate, which is durable. Then some layers of coatings are applied to enhance its corrosion resistance. So the service life of the PPGI roofing sheet will be more than 15 years.

2. Noise Reduction & Heat Insulation

The profile design of colored galvanized roofing can reduce sound resonance and isolate noise. Also, due to its low thermal conductivity, it can help to keep your home cooler on hot, sunny days.

3. Low Installation Cost

PPGI roofing sheet is light in weight so that it is easy to transport and install. Using color coated roofing sheets can shorten the construction period by 40%. Also, colored galvanized roofing can be recycled, especially for mobile houses. It can lower your construction cost.

4. Beautiful Appearance

The galvanized colour coated roofing sheet is rich in colors and unique in design, which can be used for various styles. Also, the color coated roofing looks great, which means no surface decoration is needed.

5. Good Drainage Performance

Galvanized colour coated roofing sheets are waterproofing. In rainy areas, the corrugated design can help rainwater gather and flow down quickly.

6. Excellent Safety Performance

PPGI sheet keeps the mechanical properties of base metal, such as high tensile strength, great toughness, etc. More than that, it can withstand a larger weight, when it is made into corrugated roofing.

Does Metal Roofing Make Houses Hotter?

No, it doesn’t. Metal roofing will not make a house hotter than other types of roof materials.

Let’s take PPGI for example. PPGI roofing sheets have a low thermal mass, which will reflect ultraviolet light and heat rather than absorbing. This means galvanized color coated roofing sheets can keep your home cooler on hot, sunny days. However, the heat reflection of metal roofs will be influenced by several factors:

1. Finish of Surface

Some coatings are certified to reflect sunlight, which can keep your roof cooler. For example, PVDF and HDP have great UV resistance, which is great for PPGI finish coating.

2. Color

Dark colors are going to absorb more ultraviolet light than light colors. So the surface temperature of a dark-colored steel roof will be higher. For cooling aims, you can choose light colors. More than that, the color change of dark color will be more obvious than that of a light one.

What Color Is the Best?

The PPGI roofing sheet color is a great concern of customers. It can make your house impressive and practical. Below are some factors you need to consider when choosing colors.

Climates

In general, lighter-colored roofs reflect away heat rays to keep temperatures down, while dark-colored roofs absorb heat and keep houses warm. So take the climate you live in into consideration.

Architectural Style

1. Suitable for surrounding colors

2. Suit the color of your house

Try to match the roofing color with the colors of other elements of the house like bricks, templates, stones, walls, etc. If you are not sure, please contact us for some professional advice.

Color Retention

By comparison, the color change of dark-colored roofs will be more obvious. For the aim of color retaining, you can choose light colors.
