12mm Okoume Plywood

OKOUME FACES, CHOSEN CORES AND PREPARED COMPONENTS

Choose the panel around the part you want to make

Choose 12mm Okoume Plywood for a visible wood face on joinery, coated inserts and machined components. Send a project photo, desired finish or known part sizes; our factory team helps connect the appearance, construction and supplied preparation to your next workshop operation.

The technical configuration offers 1220 × 2440mm, 1250 × 2500mm and 1525 × 3050mm sheets, with both sides calibrated and fine sanded at 150#–180#. Its 12mm ±0.35mm thickness range is 11.65–12.35mm; carry the selected supply limits into the part drawing.

Use our Okoume plywood range to compare thicknesses. The 9mm page develops lighter components, while the 18mm page develops a thicker option. Select the core, joint and hardware around the thickness ordered.

START WITH THE RESULT YOUR WORKSHOP NEEDS

Connect the component detail to the factory quotation

Begin with the visible finish, receiving part or overall length you want to achieve. We can help complete the material and sample brief, then put the controlling dimensions and operations into the drawing.

Compare quotations at the same supplied stage. Include plywood, specified processing, samples, documents and packing so each offer covers the material and work your workshop will receive.

JOINERY INSERTS, LONG PARTS AND ROUTED PANELS

Plan the construction around its finished use

CORE-SPECIFIC TRANSPORT AND MATERIAL-PLANNING WEIGHTS

Use the weight basis that matches the selected construction

A 2440 × 1220 × 12mm sheet has an area of 2.9768m² and a volume of 0.0357216m³. The all-Okoume transport configuration uses 520kg/m³, giving approximately 18.6kg per sheet with 9 plies.

The density ranges are 500–540kg/m³ for all-Okoume, 480–520kg/m³ for poplar core and 600–650kg/m³ for eucalyptus core. Keep each selected core and supplied condition with its handling and loading figures.

Keep the rounded material budget separate

The comparison below uses a 20kg per-sheet planning reference for 12mm. Dividing by 2.9768m² gives approximately 6.719kg/m². This rounded material budget is separate from the named 18.6kg all-Okoume transport configuration.

Use the selected construction's density, moisture, layup and actual dimensions in the order. The rounded thickness comparisons help organise the initial material schedule; the quotation identifies the configuration being supplied.

Plan the completed component and packed shipment

Add the joint, edging, resin, glass cloth, paint and fittings to the bare-panel weight. Where handling mass controls acceptance, weigh a completed sample. Record pallets, packing and support boards separately when preparing gross shipment data.

LONG COMPONENTS AND TAPERED CONNECTIONS

Include scarf overlap in the usable panel length

A scarf joint overlaps the mating tapered ends along the panel length. Here the ratio means horizontal bevel run : panel thickness. At a 12mm section, an 8:1 run is 96mm and a 12:1 run is 144mm. The sloping bond-line length is a separate geometric measurement.

WORKING LENGTH, OVERLAP AND FINAL TRIMMING

Turn the joined length into an input-material schedule

Starting with a 2440mm sheet, 10mm trim at each end leaves 2420mm working length. With one 96mm overlap, two untrimmed lengths give 4784mm; two trimmed lengths give 4744mm. Both input pieces carry their own end-trim allowance.

Set the input total for a six-metre component

Joined length = total working lengths − total overlaps. For a 6000mm target with two 96mm overlaps, the working lengths total 6192mm. Three equal pieces are 2064mm each: 3 × 2064 − 2 × 96 = 6000mm.

Adding final trim of 10mm at each end of the complete assembly gives a pre-trim target of 6020mm and an input total of 6212mm. Locate the joints around supports, openings and visible grain, changing the individual input lengths where the design requires.

Convert input lengths into sheet quantities

Combine the length schedule with finished width, grain direction, width trim and saw kerfs. Narrow strips can share a sheet; full-width parts use the available sheet width. Include face selection, edge cleanup, trial pieces and the agreed process allowance.

Choose full sheets, cut input pieces or accepted joined components for the quotation. The cutting layout and component count connect the geometric length to the quantity purchased.

FINISHED PANEL THICKNESS AND FINISHED CHANNEL OPENING

Include coatings on both sides of the mating detail

The first calculation uses a 12mm panel with 0.40mm on each face, giving 12.80mm finished thickness. A 13.50mm bare channel with 0.15mm on each inside wall finishes at 13.20mm. Total geometric clearance is 0.40mm.

BOTH FACES, OUTSIDE EDGES AND CUT-OUT WALLS

Calculate the surface area for the completed parts

For a rectangle of length L, width W and thickness t, both faces and all four outside edges total 2LW + 2t(L + W). Use one unit throughout, then apply the selected finish system's coverage and process allowance to that area.

For 2.440 × 1.220 × 0.012m, both faces total 5.9536m²; the four edges add 0.08784m², giving 6.04144m². Cutting separate pieces introduces more edges, so take off the finish from the actual component geometry.

The 150 × 250mm rectangle is one through-opening: subtract its area from each face and add its four cut walls. The calculation uses straight sides and square corners. Add actual radii, rebates and other machined surfaces from the drawing. For 50 components, the full rectangles total 33.44m²; the same parts with the specified openings total 30.17m².

Convert surface area into the coating purchase

Use the selected manufacturer's coverage, preparation and layer schedule. Separate face sealing, cut-edge treatment, joint adhesive, fairing and glass wet-out where their materials or rates differ. Mix resin and hardener on that system's stated basis.

A trial on the veneer and cut core establishes the production allowance for absorption, resin-to-glass ratio, equipment loss and reserve. Keep this material allowance with the geometric surface take-off when ordering the finish.

SELECTED VENEER, CUT CORE AND COMPLETE FINISH

Develop the machined detail with the visible surface

Read machining and workshop guidance

Review the wood face under the finish

Choose colour, grain, visible joints and repair range under the intended clear or opaque coating. Compare finished samples in workshop and installation lighting, including any joint crossing the show face.

Include the cut core in the selection

Review the scarf, routed opening or fixing region for core condition, breakout and repairs. Retain an uncoated section with the finished sample, keeping the core and face identities connected.

Dry-fit the mating parts

Use the chosen datum, workholding and joint section. Check the meeting bevels, aligned face and fixture support. For long parts, include the local joint and overall alignment or handling requirement in the trial.

Prepare for the selected coating

Choose tools and preparation for the supplied face and core. Record the delivered surface and further removal within the decorative veneer's allowance, following the resin or coating system's cleaning and preparation instructions.

Keep cured-epoxy surface preparation, contamination removal and recoating stages in the finishing plan, separately from preparing bare plywood for bonding.

Include reinforcement and later openings

Where the design specifies glass reinforcement, record cloth type, weight, orientation, overlaps and terminations with the resin system. Include overlap and edge-return build in the fit sample; the design defines reinforcement and strength requirements.

Schedule treatment of edges exposed by later holes and cuts. Mark bonding zones and removable interfaces before coating, and check hard-to-access surfaces at the agreed cure stage. For exposed service, select a compatible paint or varnish system with its sunlight protection and maintenance requirements.

FACTORY PREPARATION AND YOUR WORKSHOP HANDOVER

Keep the selected configuration with each production stage

Connect the sample to its construction

Identify the face, reverse, actual core, layup and bond in the quotation. Keep the coated sample and its demanding machined edge with that configuration.

Carry drawing changes through the order

Record the current revision and any change to joint ratio, finished thickness, grain or coating. Update the cut list and sample reference together.

Choose the supplied preparation

Define the surface and processing stage your team will receive, including incoming checks where it completes jointing or coating. See our production and quality information for the wider factory process.

THE SELECTED PANEL AND ITS PROJECT DOCUMENTS

Connect marine requirements to the quoted construction

For marine work, send the component duty, standard and edition with the core, bond and finish requirements. We can connect the proposed panel with the applicable product report, certification, material declaration or other requested record.

For hulls, decks, structural bulkheads and other load-bearing parts, include the responsible designer's material and joint specification. Its loading, span, bend and structural requirements guide selection and evaluation of the assembled component.

Start with 12mm marine plywood when a marine specification controls the purchase, or Okoume marine plywood when that construction is required. Keep each document request with the actual core, thickness, bond and supplied configuration.

A JOINT, INSERT OR FINISHED EDGE TO COMPARE

Choose a sample that answers the next workshop decision

Start with the use, a part reference or the finish you want. We can help complete the face, core and supplied preparation before developing the drawing and sample.

Include the most demanding exposed edge and desired wood appearance in the coating trial. Keep the accepted construction, process and dimensional record with the sample so the factory and workshop can follow the same reference.

Send drawings and finish references to sales@plywoodsupplier.cn or use the product enquiry form. Add quantity, destination and timing when known; we can complete the sample and order brief with you.

ACCEPTED PARTS AND PROTECTED DELIVERY

Carry the sample through inspection and the purchase order

Link incoming sheets, machined details and finished assemblies to the selected sample and drawing. Agree measuring locations, methods and limits for the supplied stage, with application-specific evaluation where the project requires it.

Quote the complete supplied scope

List the core, face, reverse, actual dimensions and quantities by line. Separate whole sheets, prepared joint pieces and completed components, identifying the included machining, coating, trimming, documents and labels.

Protect the accepted condition in transit

Choose flat support and face or edge protection for the delivered stage. Protect machined tapers and show edges, carry sample and production identifiers into the packing list, and use actual pack dimensions and gross mass for shipment planning.
