Corrugated Aluminum Sheet

What is corrugated aluminum sheet?

Corrugated aluminum sheet is an aluminum panel formed through a roll-forming process, featuring a wavy or arched surface appearance. Due to its lightweight and corrosion-resistant properties, this panel is widely used in roofing, fencing, and siding applications in the construction industry.

• Suitable Environment: Corrugated aluminum sheet is especially suitable for areas with frequent rainfall or coastal regions, as its corrosion resistance is superior to traditional corrugated metal sheets.
• Price Comparison: Although corrugated aluminum sheets are 20-30% more expensive than corrugated metal sheets, their long-term durability and protective performance can offset the initial cost.

• Ultra-Rib Painted White Corrugated Aluminum Sheet

  

  Ultra-Rib painted white corrugated aluminum sheet features an enhanced ribbed or ridged design to provide extra strength and rigidity. Compared to standard corrugated sheets, the "Ultra-Rib" profile typically has deeper and more pronounced ribs.

• Aluminum Stucco Embossed Mill Finish 4″ Rib

  

  The Aluminum Stucco Embossed Mill Finish with a 4″ rib has rib spacing of 4 inches. Compared to the 8-inch rib profile, it offers a more compact rib pattern. This design improves the stiffness and load-bearing capacity of the panel while maintaining a more streamlined appearance.

  Rib Height: 1″Rib Distance (Pitch): 4″

• Aluminum Stucco Embossed Mill Finish (8″ Rib)

  

  The Aluminum Stucco Embossed Mill Finish (8″ Rib) has ribs spaced 8 inches apart, offering a more pronounced rib pattern compared to shallower profiles. This design enhances the structural strength and stiffness of the panel.

  Rib Height: 1″Rib Distance (Pitch): 8″

• 7.2 Corrugated Aluminum Sheet

  

  The 7.2 Corrugated Aluminum Sheet has a rib spacing of 7.2 inches, creating a deeper rib pattern compared to shallower profiles. This deeper corrugation improves the sheet’s structural strength and stiffness.

  Rib Height: 1.5″Rib Distance (Pitch): 7.2″

• 12" rib (R Panel) Corrugated Aluminum Sheet

  

  The 12-inch Rib (R Panel) Corrugated Aluminum Sheet features a series of wide, shallow ribs (typically spaced 12 inches apart). This panel design is highly suitable for both commercial and residential buildings, offering excellent strength and weather resistance.

  Rib Height: 1 1/4″Rib Distance (Pitch):12″

Corrugated Aluminum Sheet Alloys

3003 Corrugated Aluminum Sheet

Characteristics: 3003 offers good corrosion resistance and workability with moderate strength.

Characteristics: 1100 has lower strength but excellent corrosion resistance and workability.

Applications: Primarily used in applications requiring good corrosion resistance and workability but not high strength for corrugated aluminum sheets.

Popular Corrugated Aluminum Sheets

PVDF-coated corrugated aluminum sheet

PVDF is a tough engineering thermoplastic, and PVDF coatings offer significantly greater durability, allowing colors to remain vibrant and surfaces smooth over time. PVDF-coated corrugated aluminum sheets have excellent mechanical strength and wear resistance, enduring harsh conditions. The PVDF coating also effectively resists high temperatures and long-term UV exposure, preventing fading and chalking of the aluminum sheet.

For construction projects seeking long-term stability and low maintenance, PVDF-coated corrugated aluminum sheets are undoubtedly the best choice.

Corrugated Aluminum Composite Sheets

Corrugated aluminum composite sheets are lightweight, durable, and highly corrosion-resistant, making them ideal for a variety of building and construction applications. These sheets consist of a corrugated aluminum core sandwiched between two layers of aluminum or composite material, offering excellent strength and stiffness while maintaining a lightweight structure. The corrugated design enhances structural integrity, making them perfect for roofing, cladding, and other external or internal uses.

Brushed Aluminum Corrugated

Brushed aluminum corrugated sheets have a sleek, modern aesthetic with a textured metallic finish. The brushed surface adds a refined look to the natural strength and durability of aluminum, making it ideal for decorative cladding, interior design, and architectural elements. These corrugated sheets not only look stylish but also offer excellent rust, corrosion, and weather resistance. They are typically used in environments that demand both aesthetic appeal and functional durability, such as commercial buildings, modern industrial spaces, and high-end residential applications.

What is the disadvantage of using aluminum roofing sheets?

While aluminum roofing sheets offer many advantages, such as durability, lightweight, and corrosion resistance, they also have some potential drawbacks:

• 1. Higher initial cost: Aluminum roofing sheets tend to be more expensive than other roofing materials, such as steel or asphalt shingles.
• 2. Noise: Aluminum roofing may be noisier than other materials, especially during heavy rain or hail.
• 3. Thermal expansion and contraction: Aluminum expands and contracts more with temperature changes compared to other materials.
• 4. Dents and damage: Aluminum is softer than steel and may be more prone to denting or damage during maintenance, hailstorms, falling branches, or heavy foot traffic.
• 5. Galvanic corrosion: When aluminum comes into contact with certain metals (such as copper or steel), galvanic corrosion may occur.
