The face is what your customer sees; the core affects what happens in your workshop. Compare poplar, combi, hardwood and birch-based constructions by panel weight, cut-edge quality, surface support and fixing needs. At our CUZI PLY factory, we manufacture the agreed veneer construction so your order is defined by the result you need—not a species name alone.
Work directly with CUZI PLY, your plywood manufacturer in Linyi, China, with 10 production lines. We help match the complete construction to your component and repeat-order needs.
Use these answers to compare quotations on the same construction basis and prepare a complete RFQ.
The core is the inner construction between the face and back. It may use wood veneers, wood strips or a specified composite substrate.
Specify its species, layer sequence, grain direction, joining, repairs and moisture separately from the visible face.Birch-faced plywood can use poplar, combi, hardwood or birch inner veneers; all-birch uses birch veneers throughout the defined lay-up.
The quotation identifies the complete construction and the approved production sample.Combi describes a mixed-species veneer construction selected to balance weight, machining and cost.
List the actual species, layer order, symmetry and permitted substitutions for a comparable quotation.Poplar commonly supports lighter panels, while hardwood/eucalyptus commonly supports denser edges and fastening applications.
Confirm density or panel weight, machining result and fastening requirement for the exact construction.It uses multiple wood veneers bonded with adjacent grain directions arranged for panel balance.
The specification also covers veneer quality, gaps, repairs, bond, moisture and finished thickness.It uses a strip or block wood centre with crossbands and outer veneers.
Specify strip species, width, joint pattern, moisture, crossbands and machining requirements as one construction.Red core is a commercial colour description used for some darker inner veneers.
Use the actual species or composition, density or panel weight and layer sequence in the purchase specification.Record application, face and back, core species, layer sequence, dimensions, weight, defect limits, moisture and machining.
Approve a representative sample and document any later material or process change before production.Visible species, appearance, grain and finishing requirement
Specify the inner core on its own line.Species, grade and balancing requirement
Confirm the back independently from the face.Inner layer below face/back supporting balance and surface
Its role and species are construction-specific.Internal species, thickness, joining, repair and moisture controls
Names such as combi require the complete sequence.Adhesive system and bond requirement for the intended service
Name the test method and product construction in the order.Face direction, lay-up and product axis recorded separately
Use the product-specific strength direction for structural calculations.Target, tolerance, sanding or calibration and measurement points
Record both ply count and measured finished thickness.
Compare the inner layers, exposed-edge finish and face support for your component. Specify the species and veneer sequence with the required sheet weight, machining and fixing arrangement.
Compare the inner material before selecting a decorative face. For MDF- or particleboard-core panels, discuss the finished construction with our factory; the quotation identifies the selected substrate, veneers, processing and documents. Our plywood is manufactured from selected veneers; specify a composite substrate separately from its finished face and machining.
| Core type | What is inside | What to compare |
|---|---|---|
| Veneer core plywood | Wood veneers form the inner layers, with grain directions arranged in the specified lay-up. | Choose around exposed edges, panel weight, machining and fixing. State species, layer thicknesses, gap limits and the finished panel condition. |
| Combi and combination core plywood | CUZI PLY combi plywood uses a stated mix of veneer species. Combination core can also mean a veneer centre with MDF or HDF layers beneath the decorative faces. | Write the actual layer schedule. Specify whether you want mixed wood veneers or a veneer-and-fibreboard construction; the names alone are not interchangeable. |
| MDF core plywood | Decorative veneers are bonded to a medium-density fibreboard substrate rather than a stack of inner wood veneers. | Compare surface smoothness and thickness control with finished weight, edges, fastener positions and moisture exposure. Specify the substrate grade, veneer faces and balancing back. |
| Particleboard core plywood | Decorative faces cover a bonded wood-particle substrate, also called PBC. | For furniture and interior fittings, compare the required face finish, edge banding, hardware, support and moisture conditions. Name the substrate grade and emission requirement separately. |
| Lumber core plywood and blockboard | Wood strips form the centre, with crossbands and outer veneers around them. | For doors, shelves and longer furniture parts, specify strip direction, joints and fixing locations with crossbands, thickness and finish. Do not substitute a veneer-core schedule. |
Use the same finished dimensions, face and intended component when comparing offers. Veneer layers, a fibreboard centre and a veneer centre with fibreboard crossbands create different cut edges and surface-support conditions. Check finished weight, face telegraphing, thickness tolerance, the actual fastener or joint, and the intended moisture exposure. Select the construction that fits the part rather than assuming the smoothest face also gives the best exposed edge or fixing result.
Columbia Forest Products’ core guide uses combination-core terminology for veneer inner plies with MDF or HDF crossbands. Specify your CUZI PLY layer schedule explicitly when comparing suppliers’ core names.
| Core family | Construction identity | Weight | Machining / edge | Surface / flatness | Fastening | Suitable products | Order controls | Confirm in the quotation |
|---|---|---|---|---|---|---|---|---|
| All-poplar veneer core | Pale poplar veneers in a disclosed symmetric sequence | Relatively light; quote declared density or finished-panel weight | General conversion, furniture, lining and packing | Confirm outer crossbands, calibration and face support | Approve the actual component and fastener | Poplar / Commercial / Packing | Species, ply sequence, gaps, overlaps, moisture and substitutions | Confirm weight and performance by thickness and construction |
| Hardwood / eucalyptus veneer core | Named hardwood/eucalyptus species or disclosed combination | Generally denser; actual value follows the selected construction | Robust edges and industrial machining; approve the tool result | Control repairs, uniformity and sanding | Approve the component, fastener and edge distance | Hardwood / Structural / Furniture | Species, source, density, lay-up and required testing | Add the required structural grade or test separately |
| Combi / mixed veneer core | Two or more named veneer species in a recorded sequence | Selected recipe balances weight and handling | Balances yield, edge quality and cost | Symmetry and outer crossbands support a consistent face | Approve the exact recipe and joint | Commercial / Furniture Grade / Film Faced | Species, ratio or ply count, sequence, symmetry and substitutions | Write the exact formula in the quotation |
| Birch-core / birch-dominant | Birch inner veneers or a defined birch-dominant sequence | Typically denser than many poplar constructions | Exposed edges, CNC and precision components | High-ply construction supports a uniform edge with consistent veneer control | Confirm construction, joint geometry and test requirement | Birch / Furniture Grade / Laser Cutting | Identify birch-faced, birch-core, birch-dominant or all-birch | State the birch content and complete layer sequence |
| CUZI PLY factory-produced all-birch plywood | All-birch plywood manufactured and controlled by CUZI PLY in our factory. | Declare construction, density or finished-panel weight | High-ply exposed edges and precision components | Confirm lot, grade, repairs and China processing | Approve the named product and joint requirement | Baltic Birch | Supplier, species, lot, transaction, China process and inspection | Confirm customs origin and admissibility for the named shipment |
| Lumber core / blockboard | Wood strips or blocks with crossbands, face and back | Depends on strip species, geometry and moisture | Furniture and project-selected components | Control crossbands, face/back and strip joints | Confirm strip direction, fastener and operation | Project-selected / available on request | Strip species and width, joints, moisture, crossband, face/back and thickness | Specify as a strip-core panel construction |
Record face-grain direction relative to panel length and width, together with the cutting layout and any product strength-axis instruction.
Use product-specific test values when the panel forms part of a structural design.List every inner veneer by species or approved material family and record the grain direction of each layer.
Combine ply count with species, layer sequence and grain direction.Where the product design requires a balanced lay-up, record the centre ply, corresponding layers and symmetric relationship; confirm any deliberate asymmetric construction before production.
Confirm balance against the exact ordered layer sequence.Record veneer-thickness ranges, joining, gaps, overlaps, repairs and moisture before lay-up.
These measurable fields make high-ply and thin-veneer descriptions comparable.Length and width can be made to order. Keep the construction, thickness, processing, intended use and relevant certificate or report scope with the specification.
Custom dimensions alone do not require a separate certificate for every millimetre; other product changes follow the applicable scope.Put face direction, cross banding, ply count, veneer thickness and joining requirements in one schedule. Match the face remaining after finishing and the inner quality to the visible edges, routed features and fixing zones your part actually uses.
Crossbands beneath the face and back help support the surface and set the grain arrangement. Identify their material, direction and thickness in the layer schedule, especially beneath thin decorative faces or overlays.
Odd- and even-ply constructions can use different centre layers and paired veneers. Record the grain direction and thickness on both sides of the centre. More plies alone do not establish strength, flatness or machining quality.
Distinguish the veneer thickness before pressing from the face remaining after sanding or calibration. Specify any minimum remaining face needed for your finish, with total finished thickness and the measurement method.
For visible cuts, fixing zones and routed features, agree permitted gap dimensions, frequency and location, including overlaps and repairs. Define the inspection method and representative locations; a clean outside edge does not describe every inner layer.
If your specification calls for void free plywood, state the inspected features, permitted limits and sampling plan with our factory. Keep critical visible or fixing zones explicit, and compare the agreed checks with the supplied construction rather than relying on the label alone.
Specify each veneer’s species, thickness and grain direction before pressing. Align the face direction with your cutting layout, and keep the corresponding layers balanced for the selected construction.

| Pine | Name the pine face, back and inner construction; a pine face does not identify every layer. | Construction, general-purpose panels and industrial components. | Knots, face repairs, bond and any structural product requirements. |
| Eucalyptus | State eucalyptus veneers or their position in a combi construction, rather than using only a hardwood or red-core label. | Furniture, industrial panels and machined edges. | Species description, layer schedule, weight, machining and the required product grade. |
| Okoume | Specify an okoume face separately from an all-okoume or mixed inner construction. | Selected visible faces, furniture and specified marine constructions. | Face quality, core identity, finish, bond and any named marine standard. |
Specify sound knots, loose knots and open knot holes separately on each visible side. Agree size, number, position and permitted repair under the named grade or written appearance schedule, with the paint, clear finish or overlay you will apply.
Agree patch and filler types, fit, colour, grain direction, dimensions and allowed locations. Check whether the repaired surface remains flush and suits the intended coating or laminate; a repair acceptable under paint may be visible under a clear finish.
Use the order’s face, back and inner-species schedule with material and shipment identification. Colour, a trade name or a photograph is not enough to identify all internal veneers. If a botanical species or origin document is required, include it with the quotation request.
Set permitted width, length, frequency and location, together with the sampling method used for lot acceptance.
Written acceptance limitConnect selected-core and void-control wording to measurable limits.Define overlap limits, local thickness changes, surface telegraphing and the locations included in sampling.
Surface-support controlInspect both the visible face and representative inner lay-up locations.Define a void, its permitted limit, inspection method, sample locations, lot size and acceptance decision.
Order-specific inspectionUse representative locations and the agreed sampling plan for production-lot acceptance.Record approved repair types, dimensions, quantity, location and any prohibited zones for the intended use.
Approved repair ruleSet repair limits for the intended use and visible-edge requirement.Record each layer's target thickness or range, identify critical layers and retain the applicable inspection record.
Lay-up schedule fieldRecord veneer thickness and layer sequence together with total ply count.For many dry export constructions, use 8–12% as the indicative moisture range, then confirm the product target, meter method, test locations and measurement time in the order.
Veneer + finished-panel controlThe final range follows the named product, destination and agreed measurement method.Record every layer's species, grain direction, centre ply and corresponding symmetric relationship.
Approved constructionAttach the complete lay-up schedule to combi and high-ply orders.Set finished thickness, tolerance, measurement points, sanding or calibration method and flatness acceptance.

Send the finished part, dimensions, weight target and cutting or drilling operations. Compare the complete lay-up, finished thickness and moisture alongside species. We can discuss lighter and denser constructions, then check the proposed panel with your tools and hardware before you choose a production quantity.
Discuss the face species or finish separately from the inner construction. The core must also suit surface preparation, lamination, machining and fastening. We confirm the offered combinations, balancing construction and minimum quantities in the quotation; a matching face does not mean two panels have identical weight or processing performance.
State the visible-edge locations, veneer sequence, permitted gaps and repairs, machining quality and finish. Use the actual cut or routed feature as the comparison reference. We include the agreed construction and inspection requirements in the order so edge quality is considered before production, not only when the sheets reach your workshop.
Name face and back separately, then list inner species, veneer sequence, symmetry, gap and repair limits, 8–12% moisture where appropriate, finished thickness, density or panel weight, machining and sample acceptance.
It is a mixed-veneer construction. A comparable quotation names the species, ratio, layer order, crossbands, symmetry and permitted substitutions used for the offered panel.
Choose from the required panel weight, edge and machining result, fastening operation and product use. Poplar often supports lighter panels and hardwood/eucalyptus denser panels; confirm the declared values for the offered construction.
Check the complete lay-up. Birch-faced plywood may use poplar, combi, hardwood, birch-dominant or all-birch inner construction; all-birch orders identify birch veneers throughout the specified sequence.
It is a separate project construction for uses that benefit from strip/block wood, crossbands and outer veneers. Specify strip species and width, joints, moisture, crossbands, face/back, thickness and machining.
Use the colour description together with the actual species or composition, layer sequence, density or panel weight, moisture and inspection requirements.
Define selected material, permitted gap and open-joint limits, repair limits, inspection method, sample locations, lot size and acceptance decision. This turns the description into a measurable purchase requirement.
Compare ply count with veneer species and thickness, sequence, symmetry, joining, repairs, moisture, bond and finished calibration. The complete construction determines the processing result.
State a declared-density or finished-panel-weight requirement for the exact size, thickness and moisture condition. Calculate panel weight from width × length × finished thickness × declared density, then verify the approved production sample.
Keep the agreed face, core species, complete layer schedule, machining reference, inspection requirements and lot identification with the order. CUZI PLY confirms any proposed change to material, veneer thickness, sequence, repairs or processing with you before repeat production.
Veneer core uses inner wood veneers; MDF core uses a fibreboard substrate beneath the decorative faces. Compare weight, surface support, finished thickness, exposed edges, fastening and moisture conditions for the same component. Tell CUZI PLY the finish and machining you need so the quoted panel identifies its substrate and complete construction.
Not always. Our combi veneer construction identifies a mix of wood species. Combination core may describe a veneer centre with MDF or HDF layers below the face and back. State the material, thickness and direction of every layer, and compare that schedule with your surface and hardware requirements.
Identify visible sides and the intended finish, then agree knot types, sizes, quantities and positions with the permitted patches or fillers. Check fit, colour, grain and the finished coating on that appearance reference. Keep these limits separate from the inner-core gap and bond requirements.
Regular sizes: 1220×2440, 1250×2500, 1525×3050 mm. On-request sizes: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Send the visible finish, core, machining, dimensions, quantity and destination. We confirm the construction, relevant product documents and order arrangements with your quotation.
