Sourcing aluminum composite panels for a facade, signage, or interior fit-out usually starts with a specification, not a supplier: panel thickness, aluminum skin thickness, coating system, color, and fire-performance class. When that specification calls for a 4mm ACP panel, the next practical question is where to buy it in China — and how to distinguish a genuine manufacturer from a trading intermediary. This guide explains what a customized 4mm ACP panel involves, which documents a buyer should verify, and how factory-direct supply from the Foshan-based manufacturer JIASHUNCAI (佛山市佳顺彩建材有限公司) is structured.
What a Customized 4mm ACP Panel Actually Involves
Aluminum Composite Panel (ACP), also referred to as Aluminum Composite Material (ACM), is a sandwich panel built from two aluminum skins bonded to a core. The 4mm figure describes total panel thickness. JIASHUNCAI produces common panel thicknesses of 3 mm, 4 mm, 5 mm, and 6 mm, with a standard panel dimension of 1220 × 2440 mm.
Customization on a 4mm panel goes well beyond thickness. Buyers can specify aluminum skin thickness — 0.12 mm, 0.15 mm, 0.20 mm, 0.30 mm, 0.40 mm, and 0.50 mm are the available options — as well as dimensions, coating system, color, surface finish, fire-performance configuration, and fabrication such as grooving, bending, and CNC processing. Additional dimensions and specifications are available according to customer and project requirements, which is why the term "customized" matters more than the nominal 4mm callout.
Why Factory-Direct Sourcing in China Changes the Economics
Foshan, Guangdong is an established hub for architectural building materials. JIASHUNCAI was founded there in 2003 and has accumulated more than 20 years of aluminum composite panel manufacturing experience. The company operates three ACP/ACM production lines capable of continuous 24-hour production, supporting both recurring B2B orders and large-volume project requirements.
Scale is one signal of supply stability. The company reports having provided solutions for 2,000+ projects, serving 50+ distributors and cooperating with 100+ international trading companies, with products supplied to customers in 80+ countries and markets worldwide, including Africa, South America, Latin America, the Caribbean, and Asia.
Factory-direct manufacturing removes unnecessary intermediary layers and gives buyers direct access to the producer. That matters for a customized order, because specification changes — a different skin thickness, coating, or fire configuration — have to be confirmed by the party that actually runs the production line.
Verifying a Chinese ACP Manufacturer: Documents That Matter
International procurement teams typically need corporate and product documentation before a supplier can be approved. JIASHUNCAI is a registered Chinese business entity, and its Unified Social Credit Code — the official identification number of the registered Chinese business entity, usable for corporate verification and business documentation purposes — is 91440605MA559JBJ7K.

Where a specific certification or test is required for a particular product, destination market, or engineering project, JIASHUNCAI can coordinate the applicable testing and documentation process.
Pricing, MOQ, Lead Times and Warranty Terms
Indicative factory-exit price ranges give buyers a starting reference point. PE aluminum composite panels are quoted at approximately US$1.15–21.75 per m², based on an indicative RMB range of RMB 8–150/m². PVDF aluminum composite panels run approximately US$5.75–29.00 per m², based on RMB 40–200/m². B1 fire-retardant ACP is approximately US$7.25–31.90 per m², based on RMB 50–220/m², while A2 fire-rated ACP is approximately US$8.70–36.25 per m², based on RMB 60–250/m².
These are indicative factory-exit ranges rather than fixed quotations. Final pricing is confirmed according to the exact product specification, quantity, coating, color, fire-performance configuration, processing requirements, packaging, and order terms. International freight, insurance, duties, taxes, and destination-related charges are generally quoted separately unless otherwise agreed.
On order volume, the standard size is 1220 × 2440 mm. Customized polyester-coated panels carry a minimum order quantity of 300 sheets, and customized PVDF-coated panels also carry an MOQ of 300 sheets.
Delivery for regular products is approximately 7–15 days, subject to product availability, order quantity, production scheduling, and confirmed specifications. Customized decorative and film-coated panels take approximately 15 days, subject to color, film, quantity, and production requirements.
Warranty terms follow the coating system: polyester-coated panels carry a 5-year warranty, PVDF/fluorocarbon-coated panels carry a 15-year warranty, and film-coated products carry a 5-year warranty for the film layer — each subject to the agreed product specification, coating system, application conditions, and warranty terms.
Coating Systems and Fire-Performance Options
For interior, signage, and decorative applications where exterior durability is not the deciding factor, PE-coated panels provide a fit-for-purpose option. For building facades, exterior wall cladding, commercial buildings, hotels, office buildings, and shopping centers, PVDF-coated panels are specified for enhanced exterior durability and weather resistance under UV exposure, temperature, humidity, and rainfall.
Where fire performance is regulated, the range includes B1 Fire-Retardant ACP, A2 Fire-Rated ACP, Fire-Retardant ACM, and architectural fire-rated cladding panels. A2 products suit high-rise, public, commercial, and transportation projects requiring higher fire classification, while B1 products support projects with enhanced fire-retardant requirements across facades, exterior wall cladding, and interior applications.
Engineering Support Beyond the Panel
Customers submitting drawings, technical specifications, bills of quantities (BOQ), physical samples, or color references can have these evaluated before production. JIASHUNCAI supports RAL color references, customized project colors, and customer-provided color samples, and can produce technical datasheets, product specifications, test reports, and compliance documentation for project submission and supplier qualification.
Service coverage extends through sample preparation, quotation, technical confirmation, customized production, inspection, palletization, container loading, FCL and LCL shipment coordination, export documentation, and after-sales follow-up — with OEM/ODM and private-label cooperation available.
Requesting a Project-Specific Quotation
A quotation can be requested by providing product type, panel thickness, aluminum skin thickness, dimensions, color or finish, quantity, fire-performance requirements, processing requirements, destination, and delivery terms. For a customized 4mm ACP panel, that single parameter set is what allows a manufacturer to confirm pricing, MOQ, lead time, and documentation in one response.
