Types of Roofing Sheets: How to Choose the Right Steel Sheet for Your Roof

Introduction

When building or renovating a house, warehouse, or industrial facility, the choice of roofing sheets is crucial. A reliable roof protects the structure from rain, wind, and corrosion, while also affecting energy efficiency, appearance, and long-term costs.

Among many materials, steel roofing sheets are widely used worldwide for residential, commercial, and industrial projects because of their durability, versatility, and cost-effectiveness. This article introduces the different types of roofing sheets, their technical specifications, global market preferences, and tips on how to choose the right material.

Galvanized Steel Roofing Sheets

Galvanized steel roofing sheets are one of the most common roofing materials. Produced by coating carbon steel with zinc, they provide strong resistance to rust and moisture.

• Applications: warehouses, factories, rural housing, temporary structures.
• Advantages: cost-effective, durable, easy installation.

Color Coated Roofing Sheets (PPGI / PPGL)

Color coated roofing sheets use galvanized or galvalume substrates, then apply a polyester (PE), SMP, or PVDF paint system for enhanced durability and aesthetic appearance.

• Applications: residential homes, schools, commercial buildings.
• Advantages: available in multiple colors, high weather resistance, low maintenance.

Corrugated Roofing Sheets

Corrugated metal roofing sheets are lightweight yet very strong due to their wavy profile, which also improves water drainage.

• Applications: farmhouses, sheds, garages, rural housing.
• Advantages: lightweight, strong, easy to transport and install.

Other Roofing Options

Besides galvanized, color coated, and corrugated sheets, other products are also available:

• Galvalume roofing sheets – aluminum-zinc alloy coating, highly resistant to corrosion, ideal for coastal regions.
• Tile profile roofing sheets – steel with tile-like appearance, preferred for residential houses.
• Structural metal roof panels – heavy-duty panels used in industrial buildings.

Global Market Preferences

Different regions show clear preferences for roofing steel sheets:

• Europe: Prefers high zinc coating (Z275+) and PVDF-coated sheets, ensuring long service life.
• Africa: Focused on low-cost corrugated GI sheets (Z40–Z80, 0.18–0.35 mm) for housing projects.
• Middle East: High demand for galvalume (AZ150–AZ185) sheets, resistant to high temperatures and sandstorms.
• Southeast Asia: Mix of GI and PPGI sheets, typically 0.25–0.5 mm for both residential and commercial use.
• South America: Growing demand for color coated roofing sheets, especially in urban construction.

Factors to Consider When Choosing Roofing Sheets

When evaluating the types of roofing sheets, consider:

• Durability & Corrosion Resistance
• Thickness & Load-Bearing Capacity
• Coating Type & Lifespan
• Price & Availability
• Aesthetic Requirements (color, tile profile, or corrugated design)
