A 29-ton shipment of panels is being transported to the Philippines for use in the exterior wall finishing of a local shopping mall.

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.

For procurement teams, façade contractors, and engineering companies evaluating ACP for coastal or exterior construction, the core takeaway is that coating system selection, specification detail, and supporting documentation are inseparable from product performance. PVDF coating systems are positioned by JIASHUNCAI for exterior durability and weather resistance, while fire-rated and fire-retardant options address regulatory and classification needs where applicable.

In modern architecture and urban construction, exterior materials must do more than look good. They need to withstand strong sunlight, heavy rain, wind pressure, and long-term exposure to pollution. As cities grow and buildings become more complex

Aluminum Ball Core Panel is composed of upper and lower domed hemispheres that are closely fitted together to form complete spheres. These spheres are arranged in a plum blossom pattern to constitute the spherical core layer. Together with surface aluminum sheets, bottom aluminum sheets and high flame-retardant polymer films, they are uniformly rolled and composited into integrated aluminum composite panels under set temperature, pressure, tension and traction speed, following the patented technology of JIASHUNCAI.
