PLYWOOD

Plywood is a composite 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° to one another. It is an engineered wood from the family of manufactured boards, which include medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard).

Hardboard is a tough smooth panel made with wood fibers compressed under high pressure and heat. We carry different thicknesses in both Standard grade and Tempered grade.
Hardboard has high density and high strength, which is a quality substitute for wood and is the commonly-used panel in building decoration and for furniture manufacturing. It is applied to many places such as dados, doors, roofs, partitions and furniture etc.Hardboard is made from wood fibre is extracted from chips and pulped wood waste. In the production process the pulp is exploded under pressure. Heat and steam is applies to leave a fine, fluffy brown fibres. These fibres are transformed into mats, which are held together with lignum and other glues.Also referred to as hardboard, a high density fiberboard (HDF) for flooring is a type of engineered wood product. It’s made from wood fiber extracted from chips and pulped wood waste. HDF for flooring is similar but much harder and denser than particle board or medium density fiberboard (MDF) for flooring.Hardboard is only sold in thin ??? inch or ¼ inch thick sheets. Because it is so strong and durable, hardboard can often perform as well, if not better than, other fiber boards that are 3-6 times as thick. This makes it hard to compare the price of hardboard in a fair way.Unlike solid wood, hardboard is very homogeneous with no grain. Tempered hardboard is hardboard that has been coated with a thin film of linseed oil and then baked; this gives it more water resistance, impact resistance, hardness, rigidity and tensile strength.Unlike metal siding, hardboard is resistant to rust. It is also more resistant to temperature fluctuations. It is also more resistant to dents and scratches.

Most types of wood eventually gets damaged in case of a prolonged exposure to water. However a good quality waterproof plywood is built in such a way that it offers a better degree of resistance to water, compared to natural solid wood or commercial MR grade plywood. The reason for this is that a phenolic resin (which is a synthetic plastic resin) is used for glueing all the individual plies together. Use of a such a synthetic plastic resin helps in making the plywood waterproof.
Waterproof plywood is available in all the standard sizes. The most common sizes are 8 feet by 4 feet sheets, and thickness of 18 or 19mm.
For the construction of doors, blockboard and flush doors are the preferred choice of material, instead of plywood. Flush doors have solid rectangular blocks of softwood covered on both the faces by a thin layer of ply of around 2.5 mm thickness. Flush doors are lighter in weight, cheaper and also has lesser tendency to sag and bend compared to plywood. People prefer to opt for a waterproof (BWP grade) flush door, instead of waterproof (BWR) grade plywood for their doors.
