Why PPGI Coil Dominates the Cameroon Roofing Market
Cameroon’s construction industry continues to expand rapidly in 2026, driven by urbanization and infrastructure projects. Roofing materials must withstand high humidity, heavy rainfall, and intense UV exposure. Prepainted galvanized steel coil provides the ideal balance of strength, weather resistance, and aesthetic appeal. Our RAL color PPGI range includes popular shades like RAL 3016 (coral red), RAL 6005 (moss green), and RAL 9002 (grey white), which are widely used for residential and commercial roofing in Douala, Yaoundé, and other regions.
The hot dip galvanized steel substrate ensures long service life even in coastal climates. Galvanized steel coil with a zinc coating of 80–150 g/m² per side offers superior protection against rust. Unlike bare galvanized sheets, color coated steel coil adds an extra layer of paint that reflects heat and reduces interior temperatures—a key advantage for tropical roofing. Many Cameroonian buyers now specify PPGI over traditional zinc sheets because of better durability and lower maintenance costs.

Our prepainted galvanized steel coil is available with a reverse coat of epoxy or polyester to prevent corrosion on the underside of roofing sheets. This feature is critical for Cameroonian installations where condensation can form under metal roofs. The combination of hot dip galvanized steel and high-quality paint film gives our product a lifespan of 15–20 years in tropical environments.
Color Coated Steel Coil – Customization and Availability
RAL Color PPGI Options
We maintain stock of the most popular RAL color PPGI shades for the Cameroon market. In addition to standard reds, greens, and greys, we can produce custom colors within 10–15 working days. Our color coated steel coil uses environmentally friendly paints that comply with EU REACH regulations. The paint adhesion is tested via T-bend and impact tests, ensuring the coating does not peel or crack during roll forming or installation.
Coating Types and Durability
For standard roofing applications, we recommend polyester (PE) coating with a thickness of 20–25 µm. For high-corrosion areas near the coast, silicon modified polyester (SMP) or polyvinylidene fluoride (PVDF) coatings are available. All our prepainted galvanized steel coil undergoes salt spray testing for a minimum of 500 hours. This quality control ensures that your galvanized steel coil will perform reliably in Cameroon’s humid climate.
