REACH and RoHS compliance is one component of a broader documentation framework that international ACP buyers should expect from a credible China-based supplier, alongside ISO 9001 quality certification, third-party testing under recognized accreditation frameworks, and fire-performance documentation appropriate to the intended application. Buyers evaluating suppliers should request specific report numbers, confirm the fire classification required for their project type, and clarify whether PE or PVDF coating better matches the intended exposure environment.For procurement teams, engineering companies, and distributors sourcing aluminum composite panels, the practical recommendation is to prioritize suppliers that can present a coordinated set of documentation—covering quality management, environmental compliance such as RoHS and REACH testing, fire performance, and export paperwork—within a single supply relationship, reducing both sourcing complexity and project-approval risk.
Hello. Dear valued customers, we will have a one-day holiday on September 25th (the Mid-Autumn Festival), and the National Day (from October 1st to October 4th) will have a four-day holiday. Could you please adjust these delivery times to make the arrangements.Orders will be accepted normally during the holiday period. thank you.
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.
