product description

Pre-painted Galvanized Steel (PPGI) is a pre-coated steel plate made from hot-dip galvanized steel (GI), electro-galvanized steel (EG), etc. as the base material. After surface treatment processes such as degreasing, cleaning, and chemical pretreatment, one or more layers of high-performance organic coatings are applied using continuous roller coating technology, and then baked, solidified, and cooled at high temperature.
PPGI combines the excellent anti-corrosion properties of galvanized steel sheets with the good decorative properties of organic coatings. It has rich colors, excellent weather resistance, strong corrosion resistance, good processing performance, and long service life. It is widely used in construction, home appliances, cold chain, photovoltaics, transportation, industrial manufacturing and other fields.
According to different usage environments and performance requirements, color-coated galvanized sheets can provide a variety of coating systems, including ordinary polyester (PE), high weather-resistant polyester (HDP), silicon-modified polyester (SMP), fluorocarbon (PVDF), nano-fluorocarbon (Nano PVDF), aluminum-magnesium-manganese color-coated sheets, printed color-coated sheets, etc., which can meet the requirements for weather resistance, corrosion resistance and decorative effects in different regions and different application scenarios.
Relying on complete production equipment and mature manufacturing technology, we can produce a variety of functional color-coated board products, including ordinary building color-coated boards, purification boards, cold storage boards, solar (photovoltaic) special boards, door and window profile boards, home appliance boards, writing boards, printed boards, mesh and suede color-coated boards, embossed color-coated boards, Aluminum-magnesium-manganese color-coated boards, high weather-resistant boards, silicon-modified color-coated boards, self-cleaning boards, heat-reflective (insulation) boards, antibacterial boards, acid and alkali-resistant color-coated boards, etc., have a rich product range and can be widely used in industrial plants, steel structure buildings, warehousing and logistics, clean engineering, cold chain engineering, home appliance manufacturing, new energy and other industries.
We support personalized customization of colors, specifications, coating systems, surface textures and properties, and can provide professional product selection suggestions, technical support and overall solutions based on customer project needs to help customers obtain higher product value and better engineering application effects.

Product parameters

In addition to our solid color range, we also offer a variety of special surface effects, including:

• Wood Grain:
• Stone Pattern:
• Printed Pattern:
• Embossed:
• Suede (Wrinkle/Matte):
• High Gloss:
• Camouflage and other personalized patterns

Whether it is building exterior walls, roofing systems, home appliance manufacturing, or industrial and decorative applications, we can provide you with pre-painted galvanized sheet color solutions that combine aesthetics, weather resistance and durability according to your project needs.

Product Advantages Custom Colors and Patterns

We provide a wide range of color options, which can be customized according to the RAL international standard color card, and support a variety of special surface effects such as wood grain, stone grain, printing, and embossing. Excellent decorative properties enable color-coated boards to meet the design needs of various application scenarios such as building exterior walls, roofs, home appliances and industrial manufacturing.

Long lasting coating

PPGI color-coated galvanized sheets are produced using a continuous roller coating process. The coating is uniform, has strong adhesion, and has good resistance to cracking, peeling, and weather resistance. After adopting a high-quality coating system, the color can be maintained stable for a long time under normal use conditions, effectively extending the service life of the product and reducing maintenance costs.

Excellent mechanical properties

The color-coated plate retains the excellent mechanical properties of the base steel plate, has high strength, good ductility and processing performance, and can meet various processing techniques such as shearing, bending, stamping, and profiling. At the same time, the galvanized layer and the organic coating form a double protection, which effectively improves the corrosion resistance of the product and has a longer service life than ordinary galvanized sheets.

Easy to install, cost-effective

Color-coated boards are light in weight, easy to process, and highly efficient in installation. They can be directly used in construction and industrial manufacturing without the need for secondary spraying or surface decoration. They can effectively shorten the construction cycle and reduce overall costs. The product is easy to maintain in the later period and has more economic value for long-term use.
