When specifying aluminum composite panels (ACP) for a façade, signage system, or interior fit-out, one of the most common questions architects, contractors, and procurement teams ask is whether a 3mm or 4mm panel is the better choice. The answer depends less on a fixed rule and more on project requirements, aluminum skin thickness, finish, and the application environment. JIASHUNCAI, the international brand of Foshan Jiashuncai Building Materials Co., Ltd., manufactures both thicknesses as part of its standard ACP/ACM product range, giving buyers a clear basis for comparison before placing an order.

Aluminum composite facade systems have become a practical choice for today’s buildings because

Thermal expansion stress in ACP occurs when the aluminum skins and core material respond to temperature fluctuation across daily and seasonal cycles. Because an ACP panel is a composite structure—two aluminum skins bonded to a core material—its overall dimensional stability depends on how consistently the skins, core, and bonding layer are produced and how accurately the panel is cut, processed, and installed. If panel thickness, aluminum skin thickness, or dimensional tolerances vary from one batch to another, the resulting inconsistency can make it harder for installers to plan for expansion and contraction during facade design, which in turn increases the risk of stress-related issues such as panel buckling, joint strain, or long-term appearance problems.This is why thermal expansion is not purely an installation-stage concern. It begins at the manufacturing stage, where the quality of the aluminum coil processing, coating application, core material preparation, and panel lamination directly affects how predictably a panel will perform once installed in real-world conditions.

Increasing Demand Drives Production Expansion With the rapid growth of global demand for Aluminum Composite Panels (ACP), JIASHUNCAI is proud to announce the expansion of its manufacturing capacity. Recently, a new production line has been successfully delivered to our factory and is currently under installation. This upgrade reflects the strong increase in orders from international markets and our commitment to providing fast delivery and stable supply.

Introduction to Aluminum Composite Panel Installation Aluminum Composite Panels (ACP) are widely used in modern architecture for building facades, curtain walls, signage systems, and interior decoration. Because ACP panels are lightweight, durable, and easy to fabricate, they have become one of the most popular cladding materials in commercial construction projects. However, improper installation or construction mistakes can lead to problems such as panel deformation, poor sealing, surface contamination, and weak bonding. Understanding these issues is essential for contractors, architects, and construction companies working with ACP panels. This article explains the most common aluminum composite panel construction problems and how to prevent them.
