Customer Background
This client is an international steel distributor headquartered in Turkey. We first connected at the 2025 Yapi Turkeybuild Istanbul Construction Fair. The customer maintains an established processing and sales network in Africa, primarily sourcing PPGI Coil for local processing into corrugated sheets (color steel tiles) before distribution to serve the construction markets in Guinea and surrounding regions. Following our exhibition discussions, the client was impressed by our professionalism and product quality. After multiple email exchanges and sample confirmations, we successfully secured our first collaborative order.

Advantages of PPGI Coil as Corrugated Sheet Material
The 0.45-0.47mm thick, 1000mm wide PPGI color-coated coil selected by customers represents the “preferred specification” for corrugated sheet processing. This specification achieves high material utilization and low processing waste during roll forming, effectively controlling finished product costs while balancing structural strength and decorative appeal. It delivers significant economic benefits and processing value.

Processing Applications
- Corrugated Forming: Directly processed into color steel roofing sheets with various wave heights via roll forming equipment. Suitable for residential roofs, industrial building enclosures, temporary construction barriers, and similar applications.
- Slitting & Cutting: Can be slit lengthwise as needed to produce color steel accessories, edge flashings, small hardware fittings, door/window frames, bracket connectors, etc.
- Punching & Bending: Further processed into architectural accessories like color-coated downspouts and ventilation outlets.
Advantages of 0.45-0.47mm DX51D+Z PPGI
Vibrant, Long-lasting Colors: Red and blue are popular architectural hues in West Africa, aligning with local aesthetic preferences.
Superior Coating Adhesion: Strict paint film adhesion control (T-bend performance ≤3T) ensures no cracking or peeling during corrugation forming.
Fundamental Corrosion Protection: The combination of Z20 galvanized coating and 5μm primer provides foundational corrosion resistance for corrugated sheets, suitable for Guinea’s tropical climate.
Excellent processing performance: DX51D substrate offers superior formability, enabling smooth production on high-speed corrugating lines and enhancing processing efficiency.
Outstanding cost-effectiveness: Tailored for corrugated sheet applications, the Z20 coating + 10/5μm coating configuration achieves cost optimization while maintaining quality standards.
