Corrugated Steel Sheets are wave-shaped metal panels formed through or hot rolling processes, typically made from galvanized steel, galvalume steel, or color-coated steel. Featuring regular wave-like undulations (such as trapezoidal or sinusoidal shapes), they are lightweight, high-strength, waterproof, and corrosion-resistant, making them widely used in roofing and wall enclosure systems for both industrial and civil buildings.

Product Features and Advantages

1. Waveform Design

• Common Profiles: Available in trapezoidal, sinusoidal, and Europrofile shapes, with wave heights ranging from 10mm to 80mm and wave distances from 100mm to 400mm.
• The corrugated structure enhances the rigidity and compressive strength of the sheets, reducing the need for supporting purlins.

2. Material Types

• Galvanized Corrugated Steel Sheets: Made from galvanized steel (zinc coating of 120g/m² to 275g/m²), offering an economical and durable option.
• Galvalume Corrugated Steel Sheets(e.g., AZ150): Provide superior corrosion resistance, suitable for humid or coastal environments.
• Color-Coated Corrugated Steel Sheets: Galvanized or galvalume base with a colored coating (such as PVDF or PE), available in various colors, aesthetically pleasing, and longer-lasting.

3. Lightweight and High Strength

• Thickness typically ranges from 0.3mm to 1.2mm, with lightweight properties (5kg/m² to 15kg/m²) while maintaining excellent wind resistance and snow load performance.

4. Easy Installation

• Can be fixed using self-tapping screws, interlocking connections, or clips, allowing for quick alignment with steel purlins.

5. Economic Efficiency

• Low material costs, minimal transportation and installation expenses result in overall costs being only 1/3 to 1/2 that of traditional concrete roofs.

6. Strong Durability

• The galvanized or galvalume coatings provide long-lasting corrosion protection, with lifespans of 15 to 30 years (color-coated sheets can last over 30 years).

7. Excellent Waterproof Performance

• The wave design creates natural drainage channels, and overlapping joints can be treated with sealants or specialized accessories to effectively prevent leaks.

8. Fast Construction

• Standardized sizes (widths of 600mm to 1200mm, customizable lengths) allow for easy on-site cutting and high installation efficiency.

9. Environmentally Friendly and Recyclable

• Steel materials are 100% recyclable, reducing construction waste and complying with green building standards.

10. Versatile Applications

• Suitable for pitched roofs (recommended slope ≥ 5°), wall systems, temporary structures, agricultural greenhouses, and more.
