What is Corrugated Aluminum?
Corrugated aluminum sheet, also known as aluminum tile, corrugated aluminum sheet, profiled aluminum sheet or corrugated aluminum alloy sheet, is a type of profiled sheet made by processing aluminum sheet into various waveforms through roll forming and cold bending technology. This unique corrugated structure provides the aluminum sheet with higher strength and rigidity while maintaining the lightweight characteristics of aluminum, making it an ideal material for construction, industrial, and decorative applications.
Corrugated aluminum sheet is a type of aluminum sheet that, after roll forming, is used for roofing, fencing, and wall cladding. Corrugated aluminum wall panels and roofing sheets are lightweight and corrosion-resistant. In areas with heavy rainfall or coastal regions, aluminum is a better choice compared to metal. The main drawback of corrugated aluminum is its high cost. Aluminum is 20–30% more expensive than corrugated metal.
Characteristics of Corrugated Aluminum Sheet
The main feature of corrugated aluminum sheet is the alternating ridge and trough structure formed through the roll forming process. This corrugated structure greatly improves the strength-to-weight ratio of the material, making it particularly suitable for applications requiring high resilience and lightweight properties.
- Lightweight and High Strength: Its special wave shape increases the strength of the sheet while ensuring it remains lightweight, making the overall structure more stable.
- Excellent Weather Resistance: The surface can be treated with fluorocarbon coating or anodizing, with long-lasting color (saturation above 95% even after 5 years), suitable for outdoor use.
- Versatility: With sound insulation, heat insulation, and anti-slip properties, it is suitable for roofing, exterior walls, shopfronts, and other applications.
- Fire Resistance: Corrugated aluminum sheet has fire-resistant properties.
- Easy Processing: Corrugated aluminum sheet is easy to process, suitable for machining, forming, welding, and other subsequent processes.
- Sustainability: Aluminum is recyclable, and some manufacturers also offer low-carbon aluminum products produced with recycled materials and renewable energy.

Factors Affecting Color Selection
When choosing the color of corrugated aluminum sheets, factors such as architectural style, usage environment, durability requirements, and personal preferences need to be considered to create a satisfying visual effect.
Our standard Polyvinylidene Fluoride (PVDF) has excellent chemical composition, which gives it high mechanical strength and outstanding wear resistance. This tough engineering thermoplastic has superior durability and excellent chemical resistance, capable of withstanding halogens and acids that may cause degradation. The surface of PVDF panels can endure high temperatures and strong ultraviolet exposure, while providing longer-lasting resistance to fading and chalking compared to SMP-coated panels.
By using aluminum roofing and wall panels with PVDF coatings, you will obtain painted aluminum sheets that are more durable, vibrant, and aesthetically pleasing than any other coating system.
