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.
Reducing facade fading from strong UV exposure is one of the most common technical concerns raised by architects, contractors, and façade suppliers evaluating aluminum composite panel (ACP) materials for exterior projects. Prolonged sun exposure, combined with temperature swings, humidity, rainfall, and in some cases coastal or industrial conditions, places continuous stress on the coating layer of an aluminum composite panel. When the coating system is not designed for long-term exterior performance, color fading, gloss loss, and surface degradation can occur over time, affecting both the appearance and the perceived quality of a building façade. Foshan Jiashuncai Building Materials Co., Ltd., operating internationally under the brand JIASHUNCAI, addresses this exact challenge through its PVDF Aluminum Composite Panel product line, supported by more than 20 years of manufacturing experience since the company's establishment in 2003 in Foshan, Guangdong, China.
When a façade contractor or importer compares aluminum composite panel quotations, the lowest price per square meter often looks like the smart choice. Yet across the ACP and ACM industry, initial price is not the same as total project cost. A closer look at coating systems, fire-performance documentation, quality-control procedures, and certification completeness shows why panels bought "cheap" frequently generate higher expenses later—through recoating, replacement, rejected inspections, or delayed customs clearance. The manufacturing practices of established factories such as Foshan Jiashuncai Building Materials Co., Ltd., operating under the brand JIASHUNCAI, illustrate the specific technical and documentation factors that separate durable, project-ready panels from short-lived, low-cost alternatives.
