Both Faces Are Specified
Front and back coating chemistry, color, gloss and finish are listed separately instead of assuming that the rear treatment matches the visible surface.
Two Functional Faces · Project-Specified Coating
Double Side Coated ACP Panel
Specify both faces, not just the front. DERACP double sided aluminum composite panel options are developed for projects where the reverse face is also visible, printable, decorative, frequently handled or exposed to the service environment.
From two-side coated ACP sheets for signs and partitions to double face ACP with different colors or coating roles on each side, the useful specification is the complete panel build: face coating + back coating + aluminum skins + core + total thickness + size.

Do not confuse two-sided coating with a back service coat.
If the rear face matters visually or functionally, write its coating, color and finish into the RFQ.
Buyer Definition
What Makes a Double Sided Aluminum Composite Panel Different?
Many ACP sheets have one primary decorative face and a reverse side intended mainly for bonding, handling or concealed installation. A true two-face requirement starts when the second surface also has a job to do. That job may be appearance, printing, cleaning, corrosion protection, short-term weather exposure or simply a different color for the reverse side of a sign or partition.
Two Faces Can Have Different Jobs
A sign can use white on one side and a contrasting color on the other. A partition may need decorative faces on both sides. An exposed architectural element may require weather-focused treatment on both surfaces.
Cost Follows the Real Requirement
Using a premium coating on a concealed reverse face may add unnecessary cost. The economical solution is to match each side to its actual visibility, exposure and cleaning condition.
Panel Build-Up
Specify the Two Faces as Part of One Complete ACP Construction
A coating request should never be separated from the panel underneath it. Total thickness alone does not tell a buyer how much aluminum is used, what core is supplied or whether the second face is a decorative coating or only a basic service treatment.
Procurement note: write the front and back aluminum skins separately. For appearance-sensitive jobs, also record front color, back color, gloss or texture, protective-film side and approved sample reference.
Protective FilmTemporary surface protection during handling, cutting and installation.
Face 1 CoatingPEPVDFDecorative Selected for the primary visible or exposed side.
Front Aluminum SkinThickness selected by application, rigidity, fabrication and project requirement.
Bonding Layer + CoreLDPE or project-specified fire-rated formulation, subject to the exact required documentation.
Back Aluminum SkinSpecified separately where both faces have visual or functional importance.
Face 2 CoatingCan be a finish-grade second surface when the reverse is visible, printed, cleaned or exposed.
Coating Pair Selection
Choose the Front / Back Coating Combination by How Each Side Is Used
“Double face ACP” is not one universal grade. The most useful inquiry defines what each side must do. The matrix below is a purchasing guide; final coating availability, color matching and quantity should be confirmed for the requested construction.
| Face 1 / Face 2 Direction | Best-Fit Buying Scenario | Why Buyers Choose It | What to Confirm |
|---|---|---|---|
| PE / PE | Indoor double-sided signs, partitions, retail displays, exhibition systems. | Two clean decorative faces with cost control for mainly interior or low-demand exposure. | Color on each side, gloss, print/lamination method, protective film and fabrication route. |
| PE / Contrasting PE | Wayfinding, suspended signs, channel systems, double-face displays. | Different colors can simplify downstream finishing when both sides remain visible. | Color pair, batch approval, orientation, minimum quantity and film identification. |
| PVDF / PE | One face receives meaningful exterior exposure while the reverse is protected or semi-visible. | Performance is concentrated on the exposed side rather than paying for the same exterior coating everywhere. | Which side faces weather, joint design, cleaning environment and reverse-side visibility. |
| PVDF / PVDF | Special architectural elements where both faces may receive outdoor exposure. | Allows both sides to be considered as exterior surfaces when the installation genuinely requires it. | Project feasibility, color/gloss tolerance, coating specification, aluminum skin, core and applicable tests. |
| Decorative / Decorative | Interior screens, premium displays, furniture-facing elements, architectural features. | Two finished surfaces can reduce secondary lamination or separate back finishing. | Finish family, grain/brush direction, edge detail, scratch sensitivity and sample approval. |
Technical Reference
Double Side Coated ACP Sheet Specification Guide
DERACP publishes a broad range of ACP constructions. The figures below are practical discussion points from current DERACP product information, not a single mandatory grade. Final tolerances, coating build-up, test reports and minimum quantity should be confirmed on the controlled quotation or TDS for the exact product.
| Specification Item | DERACP Discussion Range / Direction | Buyer Decision |
|---|---|---|
| Total panel thickness | Common public references span approximately 2.5–6 mm depending on product family. | Match stiffness, weight, routing/folding, support spacing and end use. |
| Aluminum skin | Published DERACP references span about 0.08–0.50 mm across different ACP categories. | State front and back skins separately; do not compare quotes only by total panel thickness. |
| Common sheet format | 1220 × 2440 mm is a widely referenced standard format. | Optimize finished size, nesting yield, pallet size and container handling before choosing custom dimensions. |
| Coating family | PE, PVDF, FEVE, NANO and selected decorative surface directions are published by DERACP. | For double-side coating, define Face 1 and Face 2 independently. |
| Core | LDPE and fire-rated core directions can be discussed by project. | For regulated uses, require the exact classification and test report that applies to the supplied construction. |
| Color / finish | Solid, metallic, matte, high gloss, brushed, mirror, wood and other project directions. | Approve an identifiable physical reference when color or texture consistency matters. |
| Protective film | Standard or project-coordinated film / branding can be discussed. | Identify which face receives film, adhesion level, logo direction and removal timing. |
| Packing | Export packing, pallet marking and edge protection can be coordinated by order. | Specify sheet count, mixed colors, pallet limits, unloading method and destination. |
Where It Adds Value
Applications That Benefit From a Finished Surface on Both Sides
Double-side coating is most useful when the second face creates a measurable fabrication, appearance or maintenance benefit. If the rear is permanently concealed, a conventional one-face decorative build may be the more rational specification.
S
Double-Sided Signage
Suspended signs, pylons, wayfinding and retail graphics where viewers can see both sides. A two-side coated ACP sheet can reduce secondary back finishing and keep edge details cleaner.
P
Partitions & Screens
Office partitions, decorative dividers and ceiling blades often expose both faces. Coordinated front and back colors make the component ready for installation after cutting, routing and folding.
R
Retail & Exhibition Systems
Display panels, kiosks, counters and temporary exhibition structures may need two presentation surfaces, rapid fabrication and repeatable branded colors.
A
Architectural Details
Canopies, fins, screens and open-backed decorative elements can expose both sides to view. Coating selection should follow the actual UV, rain, pollution and cleaning exposure on each face.
I
Interior Fabrication
Furniture-facing panels, cabinet details, wall features and column wraps can use coordinated or contrasting surfaces without adding a separate laminate to the rear.
O
OEM / Distributor Programs
Stock programs can be developed around standard sizes, repeat colors, private-label film and clearly identified face combinations for downstream fabricators.

Procurement Control
What DERACP Should Confirm Before You Approve a Two-Side Coated Panel
✓
Face 1 and Face 2 are written separately.
Coating type, color, gloss/texture and visual direction should not be hidden behind a generic “double-sided” description.
✓
Both aluminum skins are stated.
A heavier or more balanced skin construction may be important for specific routing, flatness or handling requirements.
✓
The core matches the real project condition.
For fire-sensitive work, request documents linked to the exact panel build and applicable standard rather than relying on a generic core label.
✓
Sample approval covers both faces.
Record color reference, gloss, brush/grain orientation and sample identity before a visually critical production run.
✓
Packing protects two finished surfaces.
Confirm protective film, stacking direction, interleaving if needed, edge protection, pallet marks and unloading method.
Why DERACP
Project-Based ACP Manufacturing for Buyers Who Need More Than a Generic Sheet
DERACP publishes more than 20 years of ACP manufacturing experience and six production lines. For a double side coated ACP panel, the practical advantage is the ability to discuss the complete order specification—two surface treatments, aluminum skins, core, dimensions, protective film, packing and documentation—before production.
Specification Before Price Comparison
Quotes can be aligned around the same front/back coating pair, skin thicknesses and core so purchasing teams are not comparing unlike constructions.
Custom Surface & Size Discussion
Project-based color, finish, coating, panel dimensions, protective film and export packing can be reviewed together instead of as disconnected add-ons.
Approval-Oriented Communication
For sensitive projects, buyers can request samples, controlled technical information and relevant test documents that correspond to the exact panel being considered.

FAQ
Double Side Coated ACP Panel Questions
What is a double side coated ACP panel?
It is an aluminum composite panel specified with a functional or decorative finish on both faces rather than treating the reverse only as a basic service side. For procurement, the safest wording is to list the coating, color and finish of Face 1 and Face 2 separately.
Is double sided aluminum composite panel the same as standard ACP with a back service coat?
Not necessarily. Standard ACP may use a full decorative coating on the visible face and a much simpler protective treatment on the back. If the reverse will be visible, printed, cleaned or exposed, ask for a finish-grade back specification rather than assuming the service coat is equivalent.
Can the two faces of a two-side coated ACP sheet have different colors?
Different colors or finish directions can be discussed for project orders. Confirm feasibility, minimum quantity, color approval, protective-film identification and production schedule before placing the order.
Should both faces use PVDF coating for exterior projects?
Only when both faces genuinely need exterior-grade exposure performance. If the back is concealed or protected, a full PVDF system on both faces can add cost without solving a project need. Define which side sees sun, rain, pollution and cleaning before specifying the coating pair.
What should I send DERACP for a double face ACP quotation?
Send the application, exposure, total thickness, front and back aluminum skins, core, Face 1 coating/color/finish, Face 2 coating/color/finish, width, length, quantity, fabrication method, destination and any required test, labeling or packing documents.
Can DERACP support custom sizes and private-label packing?
DERACP publishes project-based customization covering dimensions, aluminum skins, core, coating, finish, protective film and packing. Final options are confirmed against the exact requested construction, color program, order quantity and shipment plan.
Need a Double Face ACP Built Around Your Actual Application?
Send DERACP the front-face requirement, back-face requirement, panel thickness, aluminum skins, core, size, quantity and destination. The quotation can then describe a two-sided ACP construction that is easier for your technical and purchasing teams to compare.
