Perforated Aluminum Sheets

What is a Perforated Aluminum Sheet and panel?

A perforated aluminum sheet and panel refers to an aluminum sheet with regular or irregular holes processed on its surface using technologies such as CNC punching machines and laser cutting. In essence, it is a form of metal engraving art that achieves functions like light transmission, ventilation, and sound absorption through the holes.

Core Characteristics

• Lightweight and High Strength: A 3mm thick sheet weighs only 8kg/㎡, with a tensile strength of 100-280N/mm².
• Weather-Resistant and Fireproof: Fluorocarbon coating provides corrosion resistance, and it has Class A fire resistance.
• Strong Plasticity: Can be processed into flat, curved, folded, and other shapes.
• Light and Air Permeable: Holes maintain spatial permeability.
• Acoustic Optimization: Can reduce noise by 15-25dB when combined with sound-absorbing cotton.
• Light and Shadow Art: Holes filter light to form dynamic light and shadow effects.

How to Perforate?

Common perforation methods: CNC punching, stamping process, laser perforation.

Worthwill's perforation methods use CNC and combined punching machines for mass production and repeated patterns. Water jet or laser is ideal for creating custom perforations and patterns, with a variety of hole sizes and unique shapes available.

What is Perforation Rate?

Perforation rate is the percentage of the total area of perforated holes relative to the total area of the perforated region. It is a core factor affecting the overall visual perception of perforated aluminum sheet building facades and reducing building energy consumption.

The maximum perforation rate is approximately 60% (which requires the sheet size to be within 1500*3000; if exceeding this range, secondary positioning is needed). The higher the perforation rate, the greater the impact on the flatness of the aluminum sheet.

• Formula: (Total area of holes ÷ Total area of aluminum sheet) × 100%.
• Function: Determines the light transmission, ventilation rate, and acoustic performance of the aluminum sheet.
• Extreme Value: The current technical upper limit is about 60% (exceeding this value requires secondary positioning processing).

What is Hole Diameter?

Hole diameter refers to the diameter of the perforation, which is one of the factors affecting perforated aluminum sheets. Controlling the hole diameter, hole spacing, and arrangement can change the visual effect.

The most common is a hole diameter of 6mm with a pitch of 15mm.

• Range: Regular range is 0.5mm-30mm (minimum can reach 0.5mm).
• Impact: Together with hole spacing, it controls visual clarity (smaller diameters are delicate, larger diameters are rugged).

Based on the Shape of Perforated Aluminum Sheets

Flat Perforated Aluminum Sheets and Panels

The holes of flat perforated sheets are on a single plane, with a flat surface, allowing free arrangement of holes, suitable for patterned designs, and helping to enhance the integrity of the building. It is the most common type of perforated aluminum sheet.

• Flat surface, free arrangement of holes, suitable for patterned designs
• Visually transparent, does not block side vision, conducive to building integrity

Folded Perforated Sheets and Panels

Through unique folding designs, they show significant advantages in architectural design and application.

• Folding increases structural thickness, greatly enhancing strength
• Reduces vertical division, seam connections, and keels, saving costs
• Available in two types: concave-convex and zigzag, with adjustable depth and angle

Wavy Perforated Aluminum Sheets and Panels

Wavy perforated sheets are formed by arc bending on the basis of folded sheets, creating a unique wavy shape. This design not only retains the structural advantages of folded sheets but also brings softer and more artistic visual effects.

• Arc bending on the basis of folded sheets, forming a wavy softened surface contour
• Creates a hazy and ambiguous semi-transparent atmosphere with rich and soft light and shadow changes
• Softened surface contour makes it easy to integrate and adapt to the surrounding environment
• Bending treatment increases structural thickness, with high strength, reducing the number of vertical keels

Price of Perforated Aluminum Sheets

The price of perforated aluminum sheets is mainly determined by their alloy composition, sheet thickness, and hole patterns, and aluminum ingot price.

Generally speaking, the higher the content of precious metals in the alloy, the higher the price; the thicker the sheet, the higher the price; the more complex the holes, the higher the price.
