What is perforated aluminum panel? Perforated aluminum panel refers to the process of using specialized CNC equipment to punch various hole shapes on aluminum sheets. After punching various holes, the edges are pressed using a bending machine, and the surface is treated with fluorocarbon or powder coating to enhance aesthetics and prevent natural oxidation of the aluminum sheet, resulting in various colors that make the aluminum panel vibrant and decorative when installed in buildings.

Perforated aluminum panel: refers to the creation of various patterns on materials such as steel plates, leather, fabric, and wood to meet various needs.

What is the perforation rate of perforated aluminum panel?

Perforated aluminum panel is one of the aluminum panel products, and the punching mainly occurs during the sheet metal processing. After marking the punching angles, CNC engraving can be used for the punching operation. The punching ratio is one of the three main elements of perforated aluminum panels, and customers usually need to know the punching rate to customize perforated aluminum panels. So, how to understand the punching speed of perforated aluminum panels?

Before performing the perforation operation on aluminum panels, it is important to understand the concept of punching speed, as it will affect the quality of the perforation. Typically, the punching rate is calculated based on the hole size set by the customer. Punching ratio = punched area / surface area of the finished aluminum panel. In simple terms, it refers to the distance between each hole, which is the density of the panel face. A high punching rate can make the overall appearance of the aluminum panel more beautiful and attractive.

How to install perforated aluminum panel?

1. Mark the lines for the perforated aluminum panel according to the axis and elevation lines of the main structure, and accurately snap back the installation positioning lines for the supporting framework based on design requirements, providing a basis for the installation of the framework.

2. Install the connectors by fixing them to the embedded parts welded to the main structure. If there are no built-in iron parts in the main structure, holes can be drilled in the main structure to fix expansion bolts and connecting iron.

3. Install the framework, accurately fix the rust-treated steel framework to the connectors using welding or bolts according to the marked line positions. During the installation process, always confirm the elevation and centerline positions. For large area and high external wall perforated aluminum panel frameworks, vertical rods should be measured and aligned using measuring instruments to ensure they are level with the framework.

4. Install the aluminum panels, using rivets or bolts to securely attach the aluminum alloy panels to the steel framework in sections. To correct installation errors, leave a gap of 10 to 15mm between the panels.

5. Joint treatment of the panels, the gaps between aluminum panels can be tightened with rubber bands or waterproofed with elastic materials such as silicone sealant.

6. Treatment of expansion joints for perforated aluminum panels, the expansion joints of the perforated aluminum panels should meet design requirements. The treatment of expansion joints generally involves pressing a flexible neoprene molding strip onto the joint anchor to serve the purpose of connection and sealing.
