PPGI Sheet

We provide various types of premium prepainted galvanized steel coil and sheet customization（PPGI sheet coil）, including cutting, bending, stamping, punching, forming, painting, and other deep processing services.

Product Description

Structure of PPGI Steel Sheets

The structure of a color-coated sheet consists of a substrate, a chemical conversion film, a primer, and a topcoat.

• Substrate: Hot-dip galvanized steel sheet (zinc layer weight 60-275 g/m²) or aluminized zinc sheet (55% Al-Zn alloy).
• Coating: Polyester (PE), Silicon Modified Polyester (SMP), Fluorocarbon (PVDF), etc., thickness 15-25 μm.

Production Process of PPGI Sheet

PPGI is made of hot-dip galvanized steel, with the organic coating applied by rollers.

• Substrate treatment: degreasing, pickling to remove surface impurities, phosphating/passivation to enhance adhesion.
• Coating process: primer (epoxy resin) + top coat (PE/SMP/PVDF) roller coating, baking curing (220-250 ℃).
• Post-treatment: embossing (optional), cooling, winding.

Type of PPGI Prepainted Galvanized Sheet

• PPGI corrugated sheet:Commonly used as roofing and wall covering materials, due to the corrugated shape of the sheet’s surface increases its strength and bending resistance, as a building material can enhance the structural strength of the building.
• PPGI plain sheet: Often used for roofing, exterior wall covering, and home appliance production, PPGI plain sheet has a smooth and flat surface, which is aesthetically pleasing and easy to clean in large flat surface applications.
• PPGI patterned sheet:often used for anti-slip and exterior decoration, e.g., floors and stair treads. The dimpled surface of the PPGI steel plate increases the friction and anti-slip effect.
• PPGI sandwich panels:High-quality roofing and partitioning material for buildings, consisting of two color-coated sheets and a core material, which not only looks good but also provides thermal insulation and heat preservation.

What are the Features of PPGI Sheet?

• Corrosion resistance: It is protected by a zinc layer and paint, making the steel less likely to rust in various environments. In addition, coatings of different materials, such as PE, SMP, HDP, PVDF, etc., provide additional protection.
• Beautiful: ppgi sheet has a smooth and uniform appearance, and can be customized with various colors and finishes, such as wood grain/stone grain/brick grain/metal texture/flower and bird painting/abstract pattern/camouflage/antique/gradient, etc., to meet various needs Design requirements.
• Durable: The service life of plates with different material thicknesses can be as long as 7–20 years in different environments. They can also resist ultraviolet rays and withstand extreme weather.
• Processability: Both ppgi coil and sheet have good processability and can be cut, bent, and pressed into various profiles.
• Convenient to use: Compared with traditional building materials, color-coated boards are lightweight and easy to transport and process.
• Cost-effectiveness: Longer service life, low maintenance cost, more economical from the original point of view.

Comparison with Other Materials

How to Choose Between PPGI and PPGL Sheets?

PPGI and PPGL sheets are two popular types of painted metal materials. PPGI is economical and practical for general corrosion resistance needs with excellent workability, while PPGL is high-end and weather resistant for harsh environments with long life but higher cost. We can choose the most suitable type of pre-painted steel sheet according to the specific project requirements, environmental conditions, and budget.

PPGI VS PPGL

Recommendations

Is the environment high humidity/high temperature/high salt spray?

Yes → Select PPGL

└─ No → Is the budget tight?

└─ Yes → Select PPGI

└─ No → Select according to processing complexity (PPGI or PPGL)
