Sectional
Base Metal (Galvanized Steel): The core of the coil is galvanized steel, which is steel coated with a layer of zinc to provide corrosion resistance.
Chemical Treatment Layer: This layer is applied to the galvanized steel to improve adhesion of the subsequent coatings and to enhance corrosion resistance.
Primer Coating: A primer coating is applied on top of the chemical treatment layer. This layer further enhances adhesion and provides an additional barrier against corrosion.
Topcoat (Finish Coat): The topcoat is a colored paint layer that provides both aesthetic appeal and additional protection.
Back Coat (Optional): On the underside of the coil, a back coat may be applied.

Frequently Asked Questions
What thickness is recommended for roofing?
For most residential and small building projects in Africa and South America, popular thickness ranges are:
-
0.18mm – 0.30mm for general roofing
-
0.35mm – 0.50mm for industrial and warehouse roofing
Can the sheets be customized ?
Yes. Length can be cut-to-size to reduce overlap and reduce waste.
Colors can be chosen according to RAL color chart, including Red, Blue, Green, Grey, Brick Red, and Matte Wrinkle Colors
Are metal roofing sheets easy to install?
Yes. metal roofing sheets are lightweight, which makes installation fast and cost-effective. They also require lower structural support, helping to reduce total construction cost.
What are metal roofing sheets?
Metal roofing sheets are roofing materials made from steel coils such as PPGI (Prepainted Galvanized Steel), PPGL (Prepainted Galvalume Steel), GI (Galvanized Steel), and GL (Galvalume Steel). They are widely used in residential, commercial, and industrial roofing due to their durability, weather resistance, and cost-effectiveness.
Why ar roofing sheets popular in Africa and South America?
These regions experience strong sunlight, heavy rainfall, and coastal humidity. Metal roofing sheets provide excellent heat reflection, corrosion resistance, and long service life, making them suitable for tropical and coastal climate
What profile types are available?
Common metal roofing profiles include:
-
Corrugated Roofing Sheets – economical and flexible
-
Box Profile Roofing Sheets – high strength and modern appearance
-
Tile Form Roofing Sheets – decorative and suitable for homes & public buildings
How long do metal roofing sheets last?
Depending on coating and environment, metal roofing sheets typically last 15 to 35 years. Using high-quality paint systems (such as Nippon, AkzoNobel, KCC) and higher zinc or alu-zinc coating, can extend lifespan further.
Are metal roofing sheets suitable for coastal areas?
Yes, especially PPGL (Alu-Zinc coated) sheets. They provide better corrosion resistance than traditional galvanized sheets, making them ideal for coastal and high-humidity regions.
