Plywood

     

     Plywood is a sheet material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which includes medium density fiberbard (MDF) and particle board (chipboard).

     All plywoods bind resin and wood fibre sheets (cells are long, strong and thin) to form a composite material. This alternation of the grain is called cross-graining and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it is very hard to bend it perpendicular to the grain direction of the surface ply.

     Grade:

     Plywood is devided into grades A/A, AB/B, C/C, B/B and others.

     Characterictics of basic types.

 

A

Face and back veneers practically free from all defects.

A/B

Face veneers practically free from all defects. Reverse veneers with only a few small knots or discolorations.

A/BB

Face as A but reverse side permitting jointed veneers, large knots, plugs, etc.

B

Both side veneers with only a few small knots or discolorations.

B/BB

Face veneers with only a few small knots or discolorations. Reverse side permitting jointed veneers, large knots, plugs, etc.

BB

Both sides permitting jointed veneers, large knots, plugs, etc.

     Interior plywood. The basic dimensions 1525*1525 we can offer.

     Interior Birch Plywood is a high-quality construction material with an excellent durability and resistance to moisture.

     The interior plywood is easy to work with, it goes perfectly well with finish materials. It is water resistant, however it is not recommended to use it for exterior finish. This material is ideal for interior use.

     Exterior plywood / basic dimensions we can offer -1220*2440

     Exterior glued plywood is suitable for outdoor use, but because moisture affects the strength of wood, optimal performance is achieved in end uses where the wood's moisture content remains relatively low. On the other hand, subzero conditions don't affect plywood's dimensional or strength properties, which makes some special applications possible.

     Film faced Birch Plywood features a surface paper film impregnated with a phenolic resin and applied under heat and pressure

     Film faced plywood is available with a smooth glass like finish on both faces or with a mesh pattern imprinted on the face to improve anti slip properties.

     Standard sizes:

          2440 x 1220mm
          2500 x 1250mm

     Standard thicknesses:

          6mm, 9mm, 12mm, 15mm, 18mm, 21mm, 24mm

     Advantages:

  1. Film faced plywood is lightweight,
  2.  It's resistant to corrosion attack and water,
  3.  It's easily combined with other materials and
  4. It is easy to clean and cut.
  5. Treating the film faced plywood’s edges with waterproof paint makes it highly water-and wear-resistant.
  6.  Coating the film faced plywood with high-quality import films ensures hardness and damage resistance.
  7. The surface of the film faced plywood is hygienic and resistant to strong detergents, which is important for farming constructions and storage of food products.
  8. It can be used in conditions of high temperature drop, influence of moisture, detergent cleaning
  9.  Provides protection against termites.

 

Field Of Application

  1. It’s widely used in construction
  2. vehicle industry for making transport equipment containers, loading platforms,
  3. truck and trailer floors and wagons.
  4. This material is also used for making furniture such as chairs, tables, sofas, beds etc.
  5. Film faced plywood can also be used to build sliding doors, advertising boards, playground equipment, floors for sports arenas, smooth concrete casts, scaffolding, hoardings and fencings.
