Plywood under a timbering
Decorative plywood under a timbering depending on a kind of a facing covering and pitches applied at its manufacturing marks: DF-1 and DF-3 the transparent colourless and painted covering on the basis of a sulphatic paper, DF-2 and DF-4.It`s can opaque covering a paper on which the drawing usually simulating a structure of wood is put.
A plywood covering under a timbering of marks DF-1 and DF-2, made with use  pitches, less water resistance, than plywood of marks DF-3 and DF-4 with use  pitches.
To plywood manufacturing under a timbering apply an interline interval from wood of a birch and, less often, other deciduous breeds. For internal it is supposed to apply an interline interval from wood of coniferous breeds. Decorative plywood under a timbering is applied in quality
sheathered  material in building, by auto- and shipbuilding, in furniture manufacture, other areas of mechanical engineering.
Plywood for a panel board timbering and for a car - in vagono - and
the structure container make of a birch interline interval and an interline interval of coniferous breeds.
