Multiplex beech plywood is used for many different applications requiring extreme strength and hardness. It is used for a wide range of industrial & engineering uses, and in the manufacture of hard-wearing beech multiplex worktops, workbenches, and school furniture. It is often used as flooring and the manufacture of decorative furniture & shopfitting. Often it is used where lower-cost, commercial plywood products such as birch are not suitable - whether for its superior technical performance or aesthetic purposes.

The panel is often incorporated into highly decorative furniture, particularly with the plywood edges left exposed - or even accentuated - to reveal the uniform colour & grain of solid core beech throughout the panel with no open defects.

This wood is also available in the form of: beech 'Triply' 3-layer panel, beech fineline, and decorative beech veneered panels & doors

Multiplex Beech Plywood Types

Winwood Products is a beech plywood supplier offering the following configurations/options:

Beech Throughout Plywood

Multiplex Beech Plywood: Beech throughout plywood
  • 6mm 18mm, 26mm, 41mm 2550x1250mm closed core construction from stock, most thicknesses with 2.5mm thick unjointed faces (Class II+/III)
  • Pre-oiled 'Beech Multiplex' worktops produced to order - standard sizes:
    2000x750mm, 1500x750mm, 1830x762mm, 1525x762mm others by arrangement
  • To special order up to maximum 2550x1830mm
  • Can be supplied raw or precoated with lacquer, oil or special finishes

This high-quality beech throughout panel can be supplied using a combination of different veneer thicknesses.

The normal construction is generally based around 1.7mm/2.5mm core veneers with 1.7mm faces (2.5mm @ 25mm + thicker)

Panels can also be manufactured to order using veneers of 0.8mm throughout ('Piano Plywood') or 1.7mm ('Fineply') as standard - with other veneer thicknesses and/or combinations produced by agreement.

Beech throughout plywood has high mechanical properties and can be relied upon to perform in a regular and predictable manner under stressful conditions due to being made from veneers of beech throughout.

Plywood of this type is used in the manufacture of toys, vehicles, workbenches & tables, decorative furniture, and many other applications where a plywood product offering high-performance & dimensional stability in a consistant manner is required.

Beech Faced Plywood

Multiplex Beech Plywood: Beech faced plywood - beech/fir combi plywood
  • Produced to order, typically sizes 2440x1220mm, 2500x1220m & 3050x1220mm dependent upon core type
  • Standard thickness 4mm up to 50mm and above
  • Standard core options of lightweight poplar plywood, and birch plywood
  • Up to maximum 2550x1850mm, 3050x1525mm or 3600x1250mm dependent upon construction (other sizes by arrangement)
  • Can be supplied raw or coated with various coatings such as clear lacquer or oil

Beech can be mixed with other species used wholly or partly as the core, most typically using a poplar plywood, birch plywood or silver fir plywood core. Including these particular woods in the makeup of the panel core offers a product that is lighter in weight, or with birch plywood core but remains beech faced.

Plywood constructed in this manner can be supplied as 'beech twinply' - where only the face veneers are of beech, or  'beech combi plywood' in the case of poplar plywood and silver fir plywood - where every other veneer is beech.

It is possible to mix higher value woods such as ash, maple, oak, etc. into the core, for example to achieve a high quality contrasting edge effect that profiles cleanly & precisely. Other woods - specially dyed veneers for example - can be incorporated into the core to achieve a particular desired edge appearance.

Unidirectional Beech Plywood (Drawerside Plywood)

Multiplex Beech Plywood: Unidirectional beech drawerside plywood
  • Special order item in pallet quantities
  • Standard thickness 12mm up to 50mm
  • Standard panel size 2550x1250mm (other by arrangement)
  • Can be supplied raw or coated with various coatings such as clear lacquer or oil

Unidirectional beech plywood is often used where the appearance of the panel edges is of paramount importance - especially to minimize the appearance of end-grain visible along the side of the panel. This product is thefore often used as beech drawerside plywood - for making drawer sides - and for beech plywood skirtings or similar applications.

In the normal construction of this product, the core veneer directly under the face is bonded at right angles to all the other layers. This has been found to offer increased stability across the face and therefore to reduce the incidence of splitting on the face veneer.

This more unusual layup increases the bending strength & stiffness in the direction of the grain, at a small reduction across the grain.This makes the panel perform in a manner more akin to beech lumber, except with a more reliable performance due to its engineered construction. Sometimes this type of panel is called beech LVL (beech laminated veneer lumber).

Because every alternate layer is now in the same direction the number of torn fibres caused by cutting or profiling end grain is reduced, giving an overall cleaner edge finish.

Face Quality

All rotary peeled beech plywood is sanded to 80 grit as standard. (A secondary sanding at finer grit can be arranged to special order by arrangement.)

    • One split max 3mm wide at the edge up to 1/10 of the panel length allowed if repaired with filler
  • Class II:
    • As Class II+ plus...
    • Face may be jointed for width, provided veneers are very similar colour
    • One split up to 5mm wide (4mm if unfilled) up to maximum 1/5 of the panel length if repaired with filler
