PPGI material

PPGI stands for pre-painted galvanized iron, a type of color-coated steel that is often used in construction, transportation, and appliances. It is made by hot-dipping zinc-coated steel and then pre-painting it in a factory. This is different from other types of painted steel, which are painted after the zinc coating is applied.

What are the colors of PPGI sheet coil ?

Our company’s ppgi coils are custom-made and can be made in the color of your choice. We also offer a full range of RAL color tables for customers to choose from. Commonly used colors include RAL 3000, RAL 5015, RAL 9003, etc.

PPGI stands for Pre-Painted Galvanized Iron. The PPGI Sheet full name is Pre-Painted Galvanized Iron sheet. PPGI is a type of color coated steel that’s made by painting zinc-coated steel before it forms. It’s also known as pre-coated steel or coil coated steel.

‌Width‌: The width of PPGI board ranges from 600mm to 1500mm‌.

‌Length‌: The length of PPGI board ranges from 1000mm to 6000mm‌. Customized length is also available.

Plate: Plate refers to a flat steel material formed after rolling, which is usually used in the fields of construction, machinery manufacturing, etc.

‌Coil‌: Coil refers to steel rolled into a ring, which is usually used for transportation and storage. Coiled materials are generally used in the manufacture of pipes, containers, and other occasions that require a large amount of continuous materials. The surface quality and structural dimensional accuracy of the coiled materials are high, which is suitable for large-scale production and processing.

‌Strip‌: Strip usually refers to steel with a narrow width, which is often used to manufacture various mechanical parts, conveyor belts, etc. It can be flattened as needed and used in a flat shape.

The difference between coiled plate and strip steel lies mainly in its width and thickness. The width of coiled plate is wider than that of strip steel, but the thickness is relatively small. Coiled plate generally refers to a steel strip with a width of not less than 600mm, and strip steel is generally less than 600mm wide.

The price of color-coated plates varies depending on factors such as brand, specification, and material. Generally speaking, the market price ranges from several thousand yuan to tens of thousands of yuan per ton.

Among them, the material and specification of color-coated plates are also important factors in determining the price. Color-coated plates mainly include galvanized plates, aluminum plates and other materials. Different materials have different performances and prices will also vary.

The market supply and demand relationship of color-coated plates will also affect the price. When the market demand is strong, the price tends to rise; when the market supply exceeds the demand, the price may fall.

‌PPGI sheet coil‘s thickness is usually between 0.12mm and 1.0mm. Common thickness specifications include 0.18mm, 0.20mm, 0.23mm, 0.25mm, 0.30mm, 0.35mm, 0.40mm and 0.45mm‌. The thickest can be 2.0mm.

PPGI stands for Pre-Painted Galvanized Iron, meaning that the steel is coated with a layer of paint or protective coating.
There are many types of coatings, including polyester (PE), silicone-modified polyester (SMP), polyvinylidene fluoride (PVDF), and high-durability polyester (HDP).

The substrate of PPGI is galvanized steel, which is completely coated with zinc, while the substrate of PPGL is Galvalume steel, which is coated with aluminum, zinc and a small amount of silicon. Compared with the typical galvanized coating, galvalume has more excellent corrosion resistance and durability.

PPGL has better heat resistance than PPGI, being able to withstand temperatures up to 315° C. PPGL is more corrosion resistant because it has a dense aluminum layer, thus further protecting the base metal from corrosion. PPGL has a longer service life than PPGI, normally up to twice as long.

However, the cost of PPGI sheet is lower than that of PPGL sheet.

Corrugated Roofing steel sheet refers to the steel sheet structure used for roof load-bearing. It is usually formed by cold-bending galvanized steel sheet by roller pressing to form a V-shaped, U-shaped, trapezoidal or similar shaped waveform. This steel sheet can not only be used as a permanent formwork, but also for other purposes of construction. PPGI corrugated roofing sheet is the roof sheet whose base material is PPGI steel sheet.

The price of PPGI corrugated roofing steel sheets is affected by many factors. In addition to the substrate material and paint thickness, the thicker the sheet and the larger the span, the higher the price. In addition, regional differences and supply and demand also affect the price of roof panels.

‌Color-coated roofing sheets are available in a variety of colors, including red, orange, green, blue, metallic, gray, brown, black and white, etc. Its color is the color of its substrate PPGI steel sheet, which can be customized according to RAL color.
