Choosing ACP sheet sizes early can reduce unnecessary cutting, unused offcuts and procurement costs. However, the best size is not always the smallest stocked sheet or the largest panel available.
The useful comparison starts with the pieces your fabricator must cut, including any folded returns and processing allowances. These fabrication dimensions can differ significantly from the visible panel size on the elevation.
This guide explains how to compare standard and custom aluminum composite panel dimensions, calculate material yield and coordinate the cutting layout with finish direction, fabrication and installation requirements.

A 1220 × 2440 mm sheet is a common starting point for ACP purchasing. It should not be treated as the only industry standard or as the most economical option for every project.
Available dimensions depend on the manufacturer, product construction, finish and order conditions. For example, the ALPOLIC ordering guidance lists its own width and length options, illustrating why buyers should check the selected product rather than assume one universal size range.
Geely’s ACP product specifications list 1220 × 2440 mm as a standard size, alongside other dimensions. Its published options include widths of 1220, 1250, 1500 and 1570 mm, with listed lengths including 2440, 3050, 3200 and 4200 mm and a maximum stated length of 6000 mm.
These are product-page references, not confirmation that every width, length, thickness, core and finish combination is available. Obtain an order-specific size confirmation before completing the layout.
A requested length and a requested width may have different production implications. A manufacturer may offer several cut lengths within an available width, while another width may require a different production arrangement.
Ask which dimensions are stocked, regularly produced or subject to a special order. Confirm dimensional tolerances, edge condition, minimum quantities and packaging limits.
Review Geely’s aluminum composite panel range first, then request dimensions for the exact product selected.
Dimension | What It Describes | Why It Matters |
|---|---|---|
Purchased sheet size | The raw panel supplied by the manufacturer | Establishes the starting area and handling format. |
Fabrication blank size | The developed piece required before folding or final assembly | Controls nesting and cutting yield. |
Installed face size | The visible panel dimensions in the completed layout | Coordinates appearance, joints and interfaces. |
For a routed-and-folded cassette, the blank must account for returns, corners and the approved fabrication details. Do not assume that the visible face dimensions can be cut directly from the raw sheet without additional material.
The ALUCOBOND processing manual illustrates trimming and tray-panel fabrication considerations. Use the instructions and details applicable to the panel system actually being supplied.
The nominal sheet area is not always fully available for nesting. Allow for edge trimming, squareness correction, saw kerf or router spacing, and any unusable edge zones identified by the fabricator.
Joint width is a separate installation requirement. It is not calculated simply by subtracting saw kerf from the raw sheet width.
Prepare a cutting list with blank dimensions and quantities, then test it against several confirmed sheet options. Include corner pieces, reveals, parapets and opening surrounds rather than optimizing only the largest elevation.
A cutting layout may appear efficient only because it rotates pieces through 90 degrees. This may be unsuitable for directional metallic finishes, brushed surfaces or woodgrain patterns.
For products such as Geely’s wood and marble finish ACP, confirm orientation, pattern continuity and batch requirements before accepting the nesting result.
Check finish orientation before rotating pieces to improve cutting yield.
For an initial fabrication comparison, use:
Blank-area yield (%) = total accepted blank area ÷ total raw sheet area issued × 100
This measures how efficiently the issued sheets produce the required blanks. It does not measure visible facade coverage, because folded returns and other necessary blank material are included.
For illustration, one 1220 × 2440 mm sheet has an area of 2.9768 m². Four 600 × 1200 mm blanks total 2.88 m², giving a blank-area yield of approximately 96.75%.
This arrangement is feasible only if the actual trimming, kerf, tolerances and orientation requirements fit within the remaining dimensions. The 600 × 1200 mm measurements are example blank sizes, not a recommendation for finished facade modules.
Without reusable remnants, the remaining area is approximately 3.25%. If usable offcuts are retained, report them separately from scrap. Do not describe all unallocated material as landfill waste.
Match remnants to smaller scheduled pieces before calling them reusable. Check their dimensions, core, thickness, coating, finish direction and condition.
A matching color alone does not make an offcut suitable for a soffit, reveal or another application. It must satisfy that component’s specification.
Label retained pieces so they remain traceable and usable. An unorganized stack of remnants does not provide a reliable reduction in project waste.
Custom dimensions may reduce sheet count or fabrication work, but they are not automatically cheaper. Compare:
Material price and the number of sheets required.
Custom-order minimums and quantity increments.
Cutting, routing and handling time.
Packaging, freight, unloading and storage.
Lead time, replacement availability and contingency stock.
Usable remnants, scrap and disposal or recycling arrangements.
Ask for standard and custom quotations against the same panel specification and cutting list. There is no universal project-area threshold at which custom sizing becomes the cheaper option.
Sheet dimensions and unsupported spans are different. A large sheet can form a cassette supported in several locations, while a smaller flat panel may have a different fixing arrangement.
Wind resistance and deflection depend on the panel construction, aluminum skin thickness, core, geometry, support spacing, fixings and design loads.
Do not use a universal table that assigns maximum spans solely to 3, 4 or 6 mm total panel thickness. Obtain calculations or applicable test evidence for the proposed system.
Also distinguish visible waviness from load-related deflection. Larger dimensions can make flatness concerns more noticeable, but appearance alone does not diagnose the cause.
Longer components experience greater absolute thermal movement for the same material and temperature change. Joint widths, fixed and sliding points, fastener details and installation tolerances must accommodate the system’s movement requirements.
Fewer joints do not automatically make a facade more resistant to water ingress. Joint design, drainage and installation quality remain important.
Fire suitability must be established for the specified panel and its intended use within the wall assembly. Neither sheet area nor a product label alone confirms compliance with the project’s requirements.
Check saw and CNC capacity, routing tables, transport dimensions, lifting arrangements and access to the installation area. Longer or wider sheets need appropriate support to limit handling damage.
Use a representative mock-up to review appearance, joints and fabrication details. A visual mock-up does not replace structural calculations or required system testing.
Confirm the complete panel specification alongside the required sheet dimensions.
Before ordering, review the available options through Geely’s technical support page and request written confirmation of the sizes, tolerances and order conditions relevant to your selected product.
A: 1220 × 2440 mm is a common purchasing size. Other dimensions are available by product and supplier, so confirm the selected range rather than assuming one global standard.
A: No. Use the fabricator’s developed blank dimensions, including the required returns and processing details. Then allow for trimming and cutting clearances in the nesting plan.
A: Compare the accepted blank area with the raw sheet area issued. Record reusable remnants separately from scrap, and exclude facade joint gaps from the material area required.
A: No. Reduced offcuts must be weighed against price, minimum quantities, fabrication, freight, lead time and replacement availability. Compare quotations using the same cutting list.
A: Total thickness is only one variable. Skin thickness, core, cassette geometry, supports, fixings and loads also affect performance. Confirm the proposed system through appropriate engineering.
Send your panel specification, blank-size schedule, quantities, finish direction and delivery requirements to Geely Panel. Request available standard and custom dimensions, order minimums, tolerances, packaging and lead times before finalizing the purchase.
