Profile sheet PPGI Coil :
A profile sheet, specifically a PPGI (Pre-painted Galvanized Iron) coil color-coated sheet, is a type of steel sheet coated with a layer of zinc for corrosion resistance and then painted with a color finish. These sheets are commonly used in construction, roofing, and other applications due to their durability, aesthetic appeal, and resistance to harsh environmental conditions.
Here is an example of a profile sheet PPGI Coil specification:
- Base Material: Galvanized Steel (GI) or Galvalume Steel (GL)
- Substrate Thickness: Typically ranges from 0.20 mm to 1.00 mm or more, depending on the application.
Galvanizing Layer (Zinc Coating): The sheet is galvanized with zinc to prevent rust and enhance durability.
- Zinc Coating Thickness: Usually between 80 g/m² to 275 g/m² (depending on the environmental conditions).
Coating Type:
- Polyester Coating: Standard color coating for a long-lasting finish.
- PVDF (Polyvinylidene Fluoride): More durable and weather-resistant coatings.
- PE (Polyester): Standard grade with good outdoor durability.
- Smooth Surface: Common for general applications.
- Textured/Embossed: Often used for aesthetic or anti-slip purposes.
- Glossy or Matte: Available in different finishes based on preference.
- The color can vary depending on customer requirements. Some of the common colors include:
- Blue
- Red
- Green
- Grey
- White
- The color is applied through a continuous coil coating process ensuring uniformity and consistency.
- Width: Common widths are 600 mm, 900 mm, 1200 mm, and 1250 mm.
- Length: Can be customized according to project requirements.
- Tensile Strength: Typically ranges from 240 MPa to 550 MPa, depending on the grade of steel.
- Yield Strength: Around 150 MPa to 500 MPa.
- Elongation: Varies from 10% to 30%, depending on the thickness and grade.
- The zinc coating provides a good level of protection against corrosion.
- Environmental Resistance: Suitable for coastal, industrial, or residential applications
- Roofing: As roofing panels or sheets.
- Wall Cladding: Used as exterior wall panels in commercial and industrial buildings.
- False Ceiling: For interior decorative purposes.
- Fencing: For durable outdoor fences.
- Home Appliances: In some cases, used for appliances like refrigerators.
- Durability: The PPGI coating significantly increases the lifespan of the material.
- Aesthetic: Wide range of colors for a visually appealing finish.
- Weather Resistance: Withstands exposure to rain, sun, and other environmental factors.
- Corrosion Resistance: Excellent performance against rust due to the zinc coating.
- ISO 9001: Quality management standards.
- ASTM A755/A755M: Standard specification for steel sheet coated with metallic coating.
- JIS G 3312: Japanese standard for color-coated steel sheets.
Conclusion
PPGI coils with a color-coated finish are highly versatile and can be customized according to the application and aesthetic requirements. These sheets are widely used in construction, offering both functional performance and visual appeal.
