What is Corrugated GI sheet?

Corrugated GI Sheet is a steel sheet with hot-dip galvanized surface and pressed into a corrugated shape (corrugated), which has excellent corrosion resistance and structural strength. Its core material is galvanized steel coil (GI, Galvanized Iron), which is processed into a corrugated shape through cold rolling forming process and is widely used in building roofs, walls, fences and other fields. The corrugated design enhances the rigidity and drainage performance of the sheet, making it an ideal choice for tropical, rainy and high humidity areas.

Corrugated Galvanized Steel Sheet Manufacturing Process

Corrugated galvanized steel sheets are produced through two methods: one involves direct pressing of galvanized steel coils, while the other uses pre-cut galvanized steel sheets for pressing. Refer to the following production videos for reference.

Key features of corrugated galvanized sheet

• Corrosion-Resistant Durability: The hot-dip galvanized surface forms a dense protective layer, blocking air and moisture, suitable for diverse indoor and outdoor environments.
• Structural Strength: Corrugated design significantly enhances panel rigidity and load-bearing capacity, offering superior resistance to bending and deformation compared to flat sheets. Withstands high wind pressures and heavy loads.
• Lightweight and Easy Installation: Lightweight and resilient, enabling efficient transportation and installation. Directly interlocking and fixed, substantially reducing labor and project timeline costs.
• Aesthetic Versatility: Available in various surface finishes including zero zinc bloom or fine zinc bloom, compatible with RAL full-color paint coatings, balancing functionality and decorative appeal.
• High Cost-Effectiveness: Controllable costs with minimal maintenance requirements. Flexible customization of specifications (thickness, length, corrugation profile) ensures performance meets budget constraints.

Core Factors Influencing Corrugated Galvanized Steel Sheet Pricing

1. Base Material Grade

Differences in composition purity and mechanical properties directly impact pricing:

• Economy-grade base materials (e.g., CGCC): Lowest cost, suitable for general applications (e.g., temporary structures, indoor fencing).
• General-grade base materials (e.g., DX51D, DX52D): The mainstream market choice offering balanced cost-effectiveness, suitable for industrial plants, agricultural greenhouses, etc.
• Premium-grade base materials (DX53D, G550): High strength and formability, used in high wind pressure areas and special structural components (e.g., bridge guardrails), commanding the highest prices.

2. Product Specifications

• Zinc coating thickness is the core price-increasing factor, with corrosion resistance directly correlating to cost. Options include: Low zinc coating (30-60g/㎡), Medium zinc coating (80-120g/㎡), High zinc coating (150-275g/㎡).
• Thickness and Dimensions: Thickness directly impacts unit weight. Non-standard widths incur edge material waste; extra-long cut lengths (e.g., exceeding 12 meters) may require special production arrangements, both potentially incurring additional fees.
• Profile Type: Common wave profiles offer the most favorable unit pricing due to large-scale production. Custom wave heights, wave spacings, or specialized profiles require minimum order quantities and carry higher costs.

3. Processing Techniques

• Post-treatment Methods: Costs vary between standard passivation, fingerprint-resistant treatment, or chrome-free passivation (for environmental compliance).
• Color-Coated Addition: Colored galvanized corrugated sheets require pre-painting the galvanized steel before forming into color-coated corrugated sheets, adding complexity and cost.
• Special Quality Control: Fees apply for third-party inspections (e.g., SGS) or specialized export packaging.

4. Order Volume & Procurement Terms

• Order Quantity: Higher volumes qualify for greater discounts. A single purchase of 50 tons versus 500 tons may yield significantly different unit prices.
• Shipping Terms: EXW (Ex Works); FOB (Free on Board); CIF (Cost and Insurance Freight). Prices vary considerably depending on the chosen shipping method.

5. Market Fluctuation Factors

• Peak Demand Seasons: Spring and autumn typically mark peak construction seasons globally, driving strong market demand and potentially pushing prices higher.
• Currency Conversion: Appreciation of the Renminbi will correspondingly increase the USD price.

Reference Price per Ton of CGI Sheet
