ACP Sheet Thickness Matters – 4mm ACP sheet VS 6mm ACP sheet

The ACP sheet thickness and the versatility of Aluminium Composite Panels (ACP) have consistently amazed the architectural world, thanks to their range of enhanced benefits. ACP sheets, available in various thicknesses, are renowned for their ease of handling and fabrication, making them the preferred choice of architects seeking to create timeless designs. In addition, ACP panels are known for their durability and lightweight nature, which greatly simplifies the working process. The composite structure of ACP sheets ensures exceptional flatness, further enhancing their appeal in architectural applications.

What is the thickness of ACP sheet?

ACP sheets are available in 3mm, 4mm and 6mm panel thickness. While the 3mm thickness is excellent for Signage applications and interior applications, the 4mm and 6mm panel thicknesses are what we are going to focus on today.

What is the difference between 4mm and 6mm ACP sheets?

The differentiation points between the 4mm and 6mm ACP sheets from Aludecor are centred around the thickness of their respective cores, with no variation in the thickness of the Aluminium skins. While the 4mm ACP sheets, widely available across ACP sheet manufacturers, excel mainly in exterior applications than interior, offering design flexibility and weatherproof performance. On the other hand, the 6mm ACP sheets provide superior exterior durability and structural stability that can be used extensively in bungalows, shopping malls and low-rise apartments. The choice hinges on specific project needs, with the former being a perfect weather shield for facades and the latter emphasizing bold resilience for any type of project.

The 4mm ACP panel has always been considered a benchmark when it comes to extrusion design, joint dimensions and testing. CNC cutting tools, in fact, are also programmed to cut through 4mm ACP panels very easily. Now for the 6mm ACP sheets, the weight of each ACP sheet is increased by ~30-40%, and thus it requires additional safety measures to be followed in the time of installation.

The advantage of 6mm ACP sheets resides within its extra thickness which offers added stiffness to the panels.

The ASTM C393 testing procedure confirms that the 6mm Aluminium composite Panels have added stiffness. Besides, the difference between 4mm and 6mm ACP sheets’ panel deflection for wind loads is within 10%. Whether it is a 4mm ACP panel or a 6mm ACP panel, it is always framed with stiffeners and continuos extrusions at the back. Thus, both 4mm and 6mm ACP sheets are capable of handling almost the same amount of wind load.

Aludecor’s ACE Series of 6mm ACP panels are also known to be weatherproof. Swelling resistance, UV resistance, borer and termite resistance and anti-staining qualities make our ACE Series of ACPs simply irresistible.

The ACP sheet thickness plays a pivotal role in application suitability. The 4mm ACP panels exhibit versatility across various uses, making them a pragmatic choice. Conversely, the 6mm ACP sheets shine brightest in low rise bungalows or urban housings aspiring for elevated aesthetics. Whether for interior or exterior applications, both the 4mm and 6mm ACP sheets excel, seamlessly enhancing spaces such as hotels, airports, malls, and diverse commercial environments.
