What is Block Board
Blockboard is a timber-based sheet material that comprises a core, faced on both sides. The core is made from parallel, rectangular-section, bonded softwood strips (around 28mm wide); these are sandwiched between a variety of facing materials which can include veneers of softwood, hardwood, thin MDF or particle board. The assembly is glued under high pressure. The construction can be three-layer - with a single facing on each side of the core, e.g MDF or particleboard, or it can be five-layer for better stability - with two facings on each side. The grain of the facing material is usually arranged so that it is perpendicular to that of the core strips - which for reasons of strength run along the length of the board and are usually made from seasoned, lightweight timbers, such as poplar or spruce. Their moisture content is usually 12% or less.
Advantages of Block Board
Cheap price
Fine woodworking boards are made of stitching wooden boards in the middle of the two veneers. The price of the fine wooden board is cheaper than the splint. Although the vertical anti -curved pressure strength is poor, the transverse bending pressure strength is high. The fine -grained board is mainly used in furniture manufacturing, doors and windows and sleeves, partitions, fake walls, heating masks, curtain box door panels, wall boards, decoration, etc.
Good stability
The fine -grained board can be divided into two types: core boards do not spell and spell. According to the surface processing situation, it is also divided into one sides of sand and two sides of sand. Because of its light quality, good durability and easy processing, and has the characteristics of cutting thin wood surfaces, as well as the characteristics of hardness and size stability, it has become an ideal material in the furniture industry.
Low raw material requirements
The requirements for the production of fine wooden boards and the energy consumed are much lower than the production of plywood. Most of the required materials are core strips, and the core strips can be manufactured by trail wood and processing remaining substances. Therefore, the price is more favorable.
Convenient
Compared with the solid wood panel, the size of the fine woodwork plate is stable and difficult to deform. It effectively overcome the opposite sex of the wood and has a high horizontal strength. Due to the strict compliance with the principle of symmetrical group blanks, the warning and deformation of the board effectively avoids the board. The fine woodwork plate is beautiful, the surface is wide, and it is convenient to use.
The technical requirements of the fine -grained board not only need enough venues to allow the wood to have sufficient time to adapt to natural dryness, but also to control the drying process through a dry kiln. In addition, the advantages and disadvantages of their processing equipment not only require a lot of capital investment, but also the key to ensuring product processing accuracy and quality. Especially after the state for compulsory decoration and decoration of harmful substances to meet the standard, the adhesives used for fine wooden boards must be improved. This cost alone increases by about 10%. In addition, the price of raw materials is continuously improved. Therefore, it can be said that the real green and environmentally friendly details The woodworking board is not possible to make it. The E1 -class large core board that meets national standards is already slightly profitable.
Family decoration can only use E1 -level fine woodwork. If the product is the E2 -level fine woodwork, even if it is a qualified product, its formaldehyde content may exceed 3 times that of the E1 fine woodwork board, so it must not be used for home decoration. Once again, the fine woodwork board that cannot be decorated is purified and closed, especially the backplanes of the decoration, various cabinet inner plates and heating masks, etc. Experts have developed a closed formaldehyde closed dose, formaldehyde closed wax, eliminating and closure and closure The formaldehyde qi mist has the best effect while decoration.
How to Choose a Fine Block Board
The watch panel is smooth and flat, without defects, whether the thickness of the core of the board from the side is uniform, whether there is overlap, and the core phenomenon; depending on the price, do not be cheap when buying Brand products.
Stand the woodworking board on the ground, and knock on the different parts with your hands or other bluntware. The sound is even more uniform, indicating that the quality is acceptable.
Touch the surface of the fine wooden board with your hands. The high -quality fine woodworking board should feel dry, smooth and smooth, and touch the shape of no waves horizontally, indicating that the water content is low and the flatness is good.
If you have conditions, you can see the boards open and observe. See whether the texture of the plate is dense, whether there are obvious gaps and rotten and metamorphic wooden strips. There may be insect eggs in the decaying wooden strip, which will occur in the future.
Check the various signs of the product, such as whether the trademark produced by regular manufacturers, the certificate of the factory, the production address, the after -sales service telephone, the anti -counterfeiting logo, the environmental logo, the formaldehyde release, and the intensity value of the glue.
Properties of Block Board
Free pre-sales consultation
As it has core made of softwood whose density is less than that of hardwood, blockboards are light in weight as compared to plywood. Due to its lightweight nature, they are easy to transport and handle.
Surface finishing
They are available in various finishes such as laminates, wood veneers, melamine, etc. They can also be painted and polished.
Ease of working
They do not split while cutting and can be cut using regular wood work tools. Therefore, many carpenters prefer to work with blockboards!
Strength and durability
As softwoods are soft and have low strength, blockboards have moderate strength. They are fairly strong as compared to particle board and MDF, but have less strength as compared to plywood, which has cross-laminated structure. Even though they have low density, they can withstand moderate loads. Blockboards are less durable as compared to plywood.
Fitting
Blockboards have very good screw holding capacity, unlike particle board and MDF. They can hold nails very well and thus are used for making custom made furniture. Also they are used as core in flush doors, where screw holding capacity is essential.
Sound and thermal insulation
They are poor conductor of sound, heat and electricity. Thus they offer good sound and thermal insulation properties. Blockboards are used in partitions where soundproofing is required such as recording studios, radio stations, etc.
Resistance to water
Blockboards have fair resistance to water, they can be made waterproof by using BWP grade (Boiling Water Proof) resin for bonding the strips.
Resistance to warping and cracking
Blockboards have good dimensional stability when exposed to humidity, and thus they have moderate resistance to warping and cracking.
Resistance to sagging and bending
As they have stiffer structure, blockboards are less prone to sagging or bending. For furniture or any element whose length is more than 6 to 7 feet, blockboards are mostly preferred!
Block Boards Standard Sizes Available in the Market Are Given Below
As per I.S Code: 1659, the thickness of blockboards can be of 12mm, 15mm, 19mm, 25mm, 30mm, 35mm, 40mm, 45mm or 50 mm.

Block Board VS Plywood
Plywood is a sheet material manufactured from thin layers or ‘plies’ of wood glued together with an adhesive. It has different types, based on the wood used to build it, such as hardwood, softwood, alternate core and poplar ply.
Blockboard consists of a core made of wooden strips or blocks, placed edge to edge between two layers of plywood, which are then glued together under high pressure. Generally, softwood is used in blockboards.
Different types of plywood are suited for different uses. Commercial ply, also referred to as MR grade plywood is used for most interior design work like TV units, cabinets, wardrobes, sofas, chairs etc. For areas susceptible to moisture, such as the bathroom and the kitchen, Marine ply, or BWP/BWR ply is used.
Blockboards are usually preferred when lengthy pieces or wooden boards are required while making furniture. This is because blockboard is stiffer and less prone to bending, unlike plywood. Blockboard is generally used for building long book shelves, tables and benches, single and double beds, settees, and lengthy wall panels. It is light in weight, and is used extensively for building interior and exterior doors.
Plywood is less susceptible to damage by water, and is resistant to cracking. It is uniform throughout its length and breadth, and can be easily lacquered, painted, veneered and laminated. However, long pieces of plywood tend to bend at the centre. Plywood will also splinter badly when cut.
Blockboard is more prone to water damage as it is known to retain moisture. It is stiffer than plywood and less prone to bending. It is dimensionally stable, and can withstand cracking. Unlike plywood it does not split on cutting, and is easy to work with. It is available in various finishes such as plastic laminates, wood veneers, etc. It can also be painted and polished. It is lighter than plywood as its core is made of softwood.
Both plywood and blockboard are durable and can be cleaned easily. It is ideal not to expose either of them much to water unless using Marine Grade Plywood.
Commercial ply is available in thicknesses of 6mm, 12mm and 19mm. The range is Rs. 30 - Rs 60, for the different thicknesses. If you opt for high quality ply, the avg. price can go up to Rs. 80 for 19mm. For Marine ply, the avg. range is from Rs. 40 to Rs. 80 as per thickness, and can get more expensive if you opt for a high-quality ply.
Blockboards are available in thicknesses of 12mm, 15mm, 19mm, 25mm, 30mm, 35mm, 40mm, 45mm and 50mm. The price differs based on the size and thickness of the sheet, as well the type of wood used for the core. Blockboards range from Rs. 90 to Rs. 170 per sq. ft.
Processing of Blockboard
Followings are the steps of blockboard processing:
Slicing
The logs of timber are sliced at first for making the raw of blocks. Strips may be 25 mm.
Rotary Cutting
For outer layer, logs are cut at rotary cutting. Thus veneer for coating is obtained.
Gluing
To attach the slices glue or adhesives are used eg. Urea formaldehyde, Phenol formaldehyde which is called plastic resin. Exterior grade block board requires phenol formaldehyde. Gluing is done under high pressure.
Drying
The blocks are dried to reduce the moisture as well as water content left inside blocks. For drying the blocks are kept before the sun. The moisture content is reduced to 10-12%. After proper drying, they are ready for making a sandwich.
Attaching
Blocks are attached together used softwood or hardwood as required for interior or exterior grade required.
Finishing
Final finishing giving lamination, a coating is done.
