Supply Cooperation of Aluminium-Zinc Coated Color Steel Coil in Africa

Project Background
Our long-term client has invested in a roofing and cutting factory in Africa, specializing in the production of color steel tiles and other building materials for the local construction industry. With the growing demand for high-quality steel products in the African market, the client seeks a stable long-term supplier of steel coils to ensure production efficiency and product quality. After extensive market research and sample comparisons, the client identified the advantages of Chinese manufacturing and established a strategic partnership with Foshan Sunway Building Materials Co., Ltd., selecting our company as their core supplier of aluminium-zinc (AZ150) coated color steel coils.

The required product specifications include:

1.Thickness: 0.3–0.8mm (adjustable)

2.Width: 1000–1250mm (customizable)

3.Surface Treatment: Zinc-aluminium coating compliant with the RAL standard color system.

Given the product’s application in Africa’s coastal regions—characterized by high temperatures, humidity, and salt spray—the material must exhibit exceptional corrosion resistance to maintain long-term stability under harsh climatic conditions. To meet these stringent durability requirements, we have optimized the coating process and protective treatments accordingly.

Foshan Sunway Building Materials Co.,Ltd. Solution

1. Customized Production

-Based on the client's technical specifications, we collaborate with high-quality steel mills to produce customized orders, ensuring that the aluminum-zinc coating and color coating process meet the corrosion resistance standards required for Africa's coastal environments.

2.Strict Quality Control Measures

-Comprehensive Material Test Reports

Includes coating weight (e.g., AZ150 specification), hardness, and tensile strength to verify mechanical and chemical compliance.

-Salt Spray Test Certification

Conducted per ASTM B117 or ISO 9227 standards, ensuring >1,000 hours of resistance in coastal high-salt environments.

-Color Difference & Coating Adhesion Tests

ΔE < 0.5 for consistent color (RAL standards); cross-cut test (ISO 2409) confirms coating adhesion for long-term durability.

3.Packaging and Transportation:

Moisture-proof Packaging

-Inner layer: Anti-rust film

-Outer layer: Reinforced with steel sheet/wooden pallet

-Prevents moisture damage or impact during sea freight.

Container Loading Optimization

-Provides space-maximizing solutions to reduce logistics costs.

4. Container loading display
