Perforated Aluminum Sheet – playing an very important role in architectural design

Various types of perforated aluminum sheets stacked together

PAS-1: Perforated aluminum sheet

Perforated aluminum sheet, because of its light weight and good ductility, is often used as a ceiling and wall panel material. It is worth noting that the chemical stability of aluminum makes its life more guaranteed.

The hole type of perforated aluminum sheet can be produced according to customer requirements, and holes of different shapes and sizes can be arranged to produce perforated sheets with artistic atmosphere. In addition to hole type, hole diameter and layout, there can also be unique colors. And as a decorative material, it can be anodized to improve the color and strength, or through some surface treatment to achieve the effect you want, such as powder spraying, wire drawing or mirror treatment.

Features:

Compared with traditional building and renovation materials, perforated aluminum sheet has the following advantages:

Light weight. 3 mm thick aluminum plate weighs 8 kg/m², the perforated sheet with 40% open area can even reach 4.9 kg/m².
Good durability and corrosion resistance. With PVDF fluorocarbon coating, can resist acid rain, air pollution, and ultraviolet erosion, available for more than 15 years without fading.
Good craftsmanship. Using first processing and then the spray paint process, aluminum sheet can be processed into plane, arc and corrugated, and other complex geometric shapes, to meet the complex modeling requirements of the building.
Easy to Install and construct. Aluminum sheets are formed in the factory, no cutting is required at the construction site, and they can be fixed on the skeleton.
Recyclable and environmentally friendly. Aluminum plates can be 100% recycled, with high recycling residual value.

Surface Treatment

PAS-2: Anodized aluminum sheet

Anodizing is an electrochemical process that forms a high-hardness transparent oxide film on aluminum surfaces. Combined with electrolytic or organic coloring techniques, it delivers UV-resistant colors while preserving 100% aluminum recyclability. The oxide layer maintains superior corrosion resistance and natural metallic luster, making it ideal for aluminum ceilings, curtain wall panels, and elevator cabins.

PAS-3: Fluorocarbon aluminum panel

The fluorocarbon aluminum panel is coated with a fluorocarbon finish comprising primer, color coat, and clear topcoat, formulated with polyvinylidene fluoride resin (KYNAR500). This coating offers exceptional corrosion/weather resistance, withstanding acid rain, salt spray, pollutants, and UV radiation without fading/chalking, ensuring decades-long performance.

Two different colored heat transfer wood grain aluminum plates stacked together

PAS-4: Heat transfer wood grain aluminum plate

Heat transfer wood grain aluminum plates are produced by applying a fluorocarbon spray coating to aluminum plates or profiles, and then vacuum thermal transfer technology precisely imprints wood grain patterns onto the surface. Utilizing internationally advanced decorative materials, these plates feature luxurious and high-end patterns with realistic colors. They are wear-resistant, durable, free from formaldehyde and harmful gas emissions, and pose no health risks, making them an ideal choice for high-end architectural decoration.

PAS-5: Painted aluminum composite panel

The painted aluminum composite panel is coated with UV paint using either spraying or rolling techniques. UV paint is evenly applied to the surface of the panel and then quickly cured into a film by a UV curing machine. The paint film is rich and smooth, with a delicate gloss, showcasing excellent properties such as environmental friendliness, colorfastness, scratch resistance, acid and alkali resistance, and corrosion resistance, thereby enhancing the refined texture and vibrant luster of living spaces.

Installation Method

PAS-6: Ceiling Installation – Hook-on

The folded edges of aluminum composite panels typically measure 30 mm in height. The rectangular panel features interlocking edges – one inward-hooked and one outward-lapped – hence the name "hook-on panels." For specialized applications, both edges can be configured as inward-hooked or outward-lapped. This system is ideal for high-mobility ceiling applications such as airports, corridors, lobbies, and entryways.

PAS-7: Wall Installation – Offset Angle Bracket

The aluminum composite panel primarily consists of the panel, reinforcement ribs, and angle brackets. Typically, the edges of the panel are folded, and the hangers are connected to the panel with blind rivets. The panel is connected to the framework through the hangers, and bolts are welded to the back of the panel, connecting the reinforcement ribs and the panel to form a robust assembly. The reinforcement ribs enhance the rigidity of the aluminum composite panel, ensuring its resistance to wind pressure and maintaining flatness during prolonged use.
