Advantages of PPGI

Corrosion resistance

One of the key benefits of PPGI is its superior corrosion resistance. The zinc coating on the steel sheet acts as a barrier against moisture, preventing rust and corrosion from forming. This makes PPGI ideal for outdoor applications where exposure to the elements is a concern.

Durability

PPGI is known for its durability and long lifespan. The combination of galvanized steel and high-quality paint ensures that PPGI can withstand harsh weather conditions, UV rays, and physical damage. This durability makes PPGI a cost-effective choice for projects that require a long-lasting and low-maintenance material.

Aesthetic appeal

In addition to its practical benefits, PPGI also offers a wide range of aesthetic options. The paint coating can be customized in various colors, textures, and finishes to achieve the desired look for your project.

Easy installation

PPGI is easy to handle and install, making it a popular choice for both professionals and DIY enthusiasts. The lightweight nature of the material combined with its flexibility allows for quick and efficient installation, saving time and labor costs.

Environmental sustainability

PPGI is a sustainable building material that can be recycled at the end of its lifespan. The zinc coating provides an added layer of protection against environmental factors, reducing the need for frequent maintenance and replacement.

PPGI Production Process

Surface preparation and cleaning: This is the first and most important step in the galvanized steel.

Applications of PPGI

Roofing and cladding

PPGI is commonly used for roofing and cladding applications in the construction industry. Its corrosion resistance and durability make it an ideal choice for protecting buildings from the elements.

Fencing and enclosures

PPGI can also be used for fencing and enclosures in residential, commercial, and industrial settings. The customizable paint coating allows for seamless integration with the surrounding environment.

Automotive industry

PPGI is used in the automotive industry for manufacturing body panels, bumpers, and other components. Its strength and aesthetic appeal make it a preferred material for automotive applications.

Home decor and furniture

PPGI can add a touch of modernity and sophistication to home decor and furniture pieces. From wall panels to cabinets, PPGI offers endless possibilities for creating stylish and durable interior spaces.

Agricultural buildings

PPGI is a popular choice for agricultural buildings such as barns, silos, and storage sheds. Its resistance to corrosion and harsh weather conditions makes it an ideal material for protecting agricultural assets.

Differences Between GI and PPGI

GI is preferred in situations that require high resistance to corrosion and harsh environmental conditions, PPGI is used in situations where aesthetics matter or where a specific color or texture is required.

Production Process of PPGI

The stitched steel belt first enters the pre-cleaning section for alkaline water washing, alkaline water scrubbing, hot water washing, and then is dried with hot air and then enters the looper. After the looper, it enters the pretreatment section, where alkaline water treatment is performed.

Rinsing, alkaline water scrubbing, two-stage hot water rinsing, reconditioning treatment and two-stage hot water rinsing, and then hot air drying, enter the chemical coating machine, apply a layer of water-based chromium on the surface of the strip, and then pass through the chemical coating machine, enter Hot air dryer for drying.

The water-cooled roller set behind the hot air dryer cools the strip to below 40°C, enters the roller coater for one coating, and then enters the hanging curing oven for drying. Pendant curing ovens are equipped with sag detection. External curing.

The temperature of the strip steel in the furnace is 260 °C, it enters the water quenching tank, air-drying, and then enters the fine coating machine through the turning roller for fine coating, and then enters the fine coating curing furnace to dry the paint.

The strip enters the outlet looper, passes through the inspection table and the outlet shears, cuts the strip into the required small coils, and then transports the finished coils to the outlet coil seat by the unloading trolley. Finished rolls are transported by workshop crane to the packaging unit for packaging, and then sent to the finished product warehouse for storage.

Packaging and Shipping of PPGI

Packing	Sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope
Shipping	Shipped by road, sea, rail or air

FAQ

Q: What is PPGI material?

A: PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate. The term is an extension of GI which is a traditional abbreviation for Galvanized Iron.

Q: What is the process of PPGI?

A: The production of PPGI coils involves hot-dip galvanizing steel, followed by a coating process that includes cleaning, chemical pre-treatment, and application of primer and paint. This process is completed in accordance with the EN-10169-1 standard, ensuring quality and longevity.

Q: What is the life expectancy of a PPGI sheet?

A: The aluzinc coating surface protects the base steel not only by providing a barrier to corrosion elements but also by the sacrificial nature of the coating. PPGI/PPGL often remains in working order with little maintenance for 25 years or more.

Q: Which is better, PPGI or pcgi?

A: In the case of PPGI, there is a thin coating layer that consists of 18-20 microns, and continuous lines are used in the sheet manufacturing facility, and (check the meaning). In contrast, PCGI is coated with magnetically charged particles, and the thickness is around 0.6-0.8 mm.

Q: What is the composition of PPGI sheet?

A: 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.

Q: What is the standard of PPGI?

A: This standard specifies the requirements for steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process, for PPGI coils.

Q: What is the weight of PPGI?

A: The base metal of PPGI is carbon steel, whose density is about 7.85 tons/cubic meters. For example, if the PPGI sheet is 0.5 mm in thickness, 0.9 m in width, and 2.4 m in length, the weight per piece will be 0.5*0.9*2.4*7.85=8.478 kg. If you order 3,000 pieces, the total weight is about 25.4 tons.
