4mm WBP Chinese Plywood 2440x1220mm - 8'x4' Panel - General Description :
Economy-Grade Imported Hardwood Ply

The plywood surface veneers are of Okoume type hardwood that is cream to pale-brown, or Mahogany type hardwoods that are pink to red-hardwood; the plywood core veneers may be a species of poplar.
The board is normally manufactured with an odd number of plies, each ply being oriented at 90degrees to the adjacent one, to create a balanced construction. The plywood face and reverse veneers run in the direction of the length of the sheet : long-grain plywood.


Thickness tolerances of plywood - differences are allowed from the nominal thickness of the board after sanding.
In the case of 3.6mm plywood, this is from 3.2mm to 3.8mm.

Length and width dimensions of the plywood are stated within ±1mm tolerance.

Adhesives used in the plywood manufacture are Phenol (WBP type) for the core veneers, and Melamine Formaldehyde (Type 1 Exterior) for the face veneers.
This 4mm Plywood board has an external glueline WBP (Water & Boil-Proof); WBP bonded plywood generally has a high resistance to humid and wet environments, although the forces of expansion in a saturated timber veneer may cause the veneer to actually split, while the glueline itself is sound - This does not indicate that the Plywood has been manufacturer incorrectly - timber is a natural material subject to swelling when it absorbs moisture. Be aware that Poplar does not posses a high resistance to fungal decay in humid conditions. For long service in these conditions, design consi­dera­tions and the appropriate weather-proof finish of the plywood are of the highest importance. The timber (especially end-grain) would need to be coated and maintained to a BS-CP external specification for any external use.

Plywood face grading is stated as B/BB
- a B plywood face is described as a neatly cut veneer, substantially defect free and sanded smooth;
- a BB plywood face allows minor defects, so long as they are filled and sanded.
These plywood face-grade descriptions are summarised from BS6566 - (which although not a current standard, has been adopted as a description by several Plywood Mills.)
Long-grain hardwood veneered plywood - many boards have a decorative veneer but would have to be selected if required for this use;


- Current stock has a nice medium red/brown tight grain on the face side, with a paler cream/brown reverse side;
- .. Plies with 2 Poplar / Light Coloured Plies, and a centre Ply of a Darker Hardwood;
- Measured Thickness ...mm- ../../2016 -


Weight per 8x4 x 1/8" plywood board is approximately 7Kg;

Moisture content of the plywood is approximately 10%;

Plywood Strength Data - non declared, not CE marked for structural use.

Applications - Furniture, Shopfitting, Exhibition Stands and general construction work.
These plywood boards have not been CE grade tested for structural uses such as floor decking, roof decking or wall sheathing - (although they are of comparable quality to ones that are CE marked.) We would be able to supply a CE marked plywood, but this would be at a higher price.
