Plywood is one of the most versatile construction materials available and has wide industrial usage. Plywood is an engineered wood that is made by gluing together separate sheets or plies of wood into one strong material. It is strong, durable and economical and does not warp or break easily. Plywood for industrial usage comes with varying degrees of strength and properties depending on the timber from which it is made. Based on these properties, the type of plywood are chosen according to where it would be used.

The different uses of plywood as a construction material:

Plywood for industrial usage has a large domain.

  • For making partitions and walls
  • To make moulds for wet concrete
  • To make larger furniture like cabinets, cupboards and office tables
  • For making floors
  • For packaging and making packing boxes
  • For making doors and shutters
  • As roof and wall bracing
  • In ship constructions
  • For making different interior game stadiums
  • For making furniture
  • For making  musical instruments

The different types of plywood for industrial usage and where they are used:

There are mainly four types of plywood groupings.

  1. Structural plywood

Structural plywood is used in making permanent structures where high strength and durability is needed. It is usually made of hardwood. Structural plywood should be such that they can withstand all extremities of climatic conditions and hold under a lot of stress. Since this plywood is more about strength than appearance, it often has a lot of knots and holes as its role does not require much aesthetics. Some of the notable uses of structural plywood are in:

  • Beams
  • Flooring and sub floor
  • Wall bracing
  • Roof bracing
  • Shipping crates
  • Some interior structures
  • Hoardings
  • Outdoor furniture
  • Exterior plywood

Another important type of plywood for industrial usage is the exterior or external plywood. As the name suggests, it is mainly for outdoor use, hence it needs to be completely water resistant. For this purpose, these types of plywood are bound together by water resistant glue. These are often given a layer of paint as a further protective layer. Unlike structural plywood, these are used where a decorative or aesthetic finish is important. It is not used to bear heavy load or stress. The most suitable applications of this plywood are:

  • Wall cladding
  • Outdoor flooring
  • Exterior door surfaces
  • Stables
  • Roof linings
  • Interior plywood

Interior or internal plywood is the third important type of plywood for industrial usage. This type of plywood is best suited for all kinds of interior usage. They have a good appearance and finish. However, this plywood is not very resistant to moisture or heat hence should not be exposed to extreme weather conditions for long time. Aesthetics is somewhat more important than durability for this type. The suitable applications for interior plywood are:

  • Interior cladding
  • Indoor furniture
  • Ceiling
  • Wall paneling
  • Decorative structures
  • Flooring, but not for floors that come in direct contact with water such as bathroom floors. In that case exterior or marine plywood should be used.
  • Marine plywood

The last important type of plywood for industrial usage is the marine plywood, which is used in building ships and boats. To make it completely resistant to water damage, this type of plywood is specially treated using preservatives, paints and varnishes. It is also resistant to fungal attacks, rotting on exposure to moisture and does not delaminate. Other than ship building, it is also used in any area needing extreme waterproofing. It has high stress grade. The major uses of marine plywood are in making:

  • Docks
  • Boats
  • Ships
  • Outdoor benches
  • Planter boxes
