What Is Formwork Plywood? Formwork plywood, also known as building shuttering plywood or wooden shuttering, is used extensively in the construction industry. It is a unique type of plywood used to form framework or molds of a building structure. It is particularly used when pouring and setting concrete to allow the concrete to take shape and size.   Read More: Different Types Of Plywood     Formwork Plywood Vs Regular Plywood Material: Formwork plywood is made from the wood of the hardest and most durable trees, such as birch or pine, so they are strong enough to support heavy loads and to withstand natural elements such as wind, rain, and snow. Standard plywood is made from cheaper, softer, and less hard trees, which are not very resistant either way, and are not waterproof.   Durability and waterproof performance: Due to the particularity of the use environment, the template plywood is specially treated in production to improve its durability and waterproofness. For example, a waterproof membrane is attached to it. While the ordinary plywood is not processed in a special way.   Application field: The main application field of formwork plywood is the construction industry. However, ordinary plywood can be used in furniture manufacturing, interior decoration, and packaging.   Price gap: First of all, the plywood used as formwork board has more stringent selection of materials and production process, and needs to have better use performance than ordinary plywood, so its price will be higher than that of ordinary plywood. However, it may be more cost-effective per use in the long run.     Characteristics Of Formwork Plywood High water resistance: The plywood of the formwork is made of special waterproof glue, and the high temperature and high pressure during the plywood production will ensure that it has strong water resistance. And even when it is exposed to moisture for a long time, or used in a humid environment, it can still play a stable role.   High strength and durability: The quality wood materials used in the plywood are produced with precision instruments and using advanced technologies in the manufacturing process. The high-performance formwork plywood can carry heavy loads and withstand wear and tear and is not easily deformed during its repetitive use, which will extend the life of the product.   Reusability: Due to the high quality of the Reusable formwork plywood panel, it can be recycled many times and can still be in operation with good quality from 50 to 100 times in general, with good performance.   High construction efficiency: The size can be quickly adjusted and the formwork plywood is easy to cut and install according to the needs of the project, which improves the construction efficiency. The smooth surface of the formwork plywood also helps to form a smooth and beautiful surface after the concrete is poured.   Environmental protection: The reusability of formwork plywood can reduce the consumption of wood resources compared with single-use formwork materials, which is beneficial to the environment.   Cost-Effectiveness: Although the initial cost for formwork plywood is higher compared to some other formwork materials, it is very durable and can be reused many times with low long-term costs when considered on cost per use basis, making it cost-effective.     Plywood Application   Formwork for concrete pouring:   Because of its high strength and water resistance, formwork plywood can be used as a formwork for concrete pouring. It can be made into different shapes and sizes as per the requirements of the structure, such as pouring walls, columns, beams and floor slabs.   Roof and floor construction:   Owing to the fantastic load-bearing and waterproofing properties of formwork plywood, it is widely used in roof and floor construction, particularly in cases where fast construction is needed and high waterproofing requirements have to be met.   Forming of complex structures:   When it comes to the need of forming complex structures, for example bridges and tunnels, formwork plywood can be the finest solution for carrying out these tricky projects, since it is highly plasticable and of sufficient strength.   Eco-friendly and cost-efficient benefits:   The formwork plywood can be reused, which results in less material waste and a lesser consumption of wood resources and, at the same time, a lower cost for the whole project.     Send Us An Inquiry For Formwork Plywood Products.   Formwork Plywood Size And Thickness The size and thickness of the formwork plywood are important specifications for the application of the formwork plywood in the construction industry, related to the strength, stability and whether it can meet the requirements of specific projects. Common size and thickness have the following specifications:   Size: The most common formwork plywood size is 1220mm x 2440mm (4ft x 8ft); 915mm x 1830mm (3 feet x 6 feet). Other larger or smaller sizes can be customized according to the project requirements.   Thickness: The minimum thickness of building formwork plywood is 6mm. Common thicknesses also include 9mm, 12mm, 15mm, 18mm, 21mm, etc. The above thicknesses can be selected according to the specific needs of the project. Generally, the requirements of the thickness of the formwork board are higher for materials with heavy loads or repeated use times.     Formwork Plywood Weight The weight of formwork plywood depends on the size of the material, the thickness and the density of the plywood material. Normally, the density of the plywood is between 550 -750 kilograms per cubic meter. The weight can be taken as the product of the density of the plywood and its volume. Common dimensions of the plywood panels are 1220 mm x 2440 mm.   The following data gives the approximate weight of the plywood: For 6 mm thick plywood, the approximate weight is 8.8 -11.3 kilogram per square meter. For 12 mm thick plywood, the approximate weight is 17.6 -22.6 kilogram per square meter. For 18 mm thick plywood, the approximate weight is 26.4 -33.9 kilogram per square meter.   (Please note that the weights stated here are approximations based on using a standard size piece of plywood of 1220mm x 2440mm, and the actual weight of a given piece of plywood can vary depending on the type of material used - such as pine, birch etc. Wood is a material that absorbs water, so humidity can also influence the weight of plywood.)     Formwork Plywood Grade First Grade (Grade A): This is the highest quality grade of plywood, with an immaculately flat and smooth surface which is free of defects such as cracks, scars and filled-in holes. It is typically used in applications for which a premium aesthetic finish is required.   Second Grade (Grade B): Grade B plywood is of slightly lower quality than Grade A and may have minor flaws such as small scabs or hairline cracks. Despite these minor flaws, Grade B plywood still has good structural properties and is suitable for most construction and engineering projects.   Third grade (Grade C): Grade C plywood has obvious defects, such as cracks, scars, holes, etc., but these defects will not affect its structural performance. This grade of plywood is typically used in structural applications or temporary structures where high cosmetic quality is not required.   Fourth Grade (Grade D): Grade D plywood is the lowest quality and has more defects, which may include larger cracks and scars. This grade of plywood is primarily used for temporary works or other non-structural applications where appearance and some structural properties are not major considerations.       Why Choose AJ Building We are a famous supplier and manufacturer of Formwork Plywood in China, we will give you the advantages of our company in Formwork Plywood: Use of high-quality raw materials: The wood used to produce formwork plywood has been carefully selected by our quality inspection department to ensure that they have good durability and strength and can be used for a long time without deformation.   Diverse grades and sizes: We can provide you with different grades of plywood products on the market, and in addition to standard sizes, we can also provide customized services in size, thickness, coating, etc. according to your needs.   Competitive prices: We cooperate with more than 160 countries and regions around the world, so we save production costs through mass production while ensuring product quality.

  Plywood Size Introduction         Plywood is perhaps among the most widely used building materials. It is applied in construction, assembly work, furniture, cabinets, and even decorative projects. That is why it is important to know the dimensions of plywood so as to select the very right kind for each project, which in turn helps reduce waste and thus assure a good fit and structural integrity. Standard plywood sizes are not uniform around the world. America, India, the United Kingdom, and the Philippines all have their own traditionally favored sizes, which quite often influences their availability-a range for compatibility in the local markets.             What Is The Standard Size Of A Sheet Of Plywood         Plywood is available in several different standard sizes and special thicknesses, depending on its applications in construction, furniture, and other fields. While some sizes are standard across industries, size is also determined by regional and purpose-specific factors.   Common Industry Sizes: The most widely used sizes include the standard 4 ft x 8 ft (1.22 m x 2.44 m), due to being apt for various construction jobs because of compatibility with common framing systems. Another very common size is 5 ft x 5 ft (1.52 m x 1.52 m). This is especially prevalent in Europe, being widely used for specific applications to furnishing and cabinetry.   Standard Thickness Options: Plywood is sold in various deviated thicknesses, commonly expressed in inches or millimeters. Common plywood standard thickness mm include:   1/4 inch (6 mm): This thickness is suitable for small projects or projects that require only simple folding-such as lining or sliding drawers. 1/2 inch (12 mm): Often used to make furniture or cabinets. This is a typical thickness for a typical half-inch plywood subfloor, but not suitable for all subflooring application examples. 3/4-inch (18 mm): This is the most common plywood thickness, suitable for almost all plywood construction. This is also a suitable floor or ceiling thickness.             Regional Differences In Plywood Sheet Size         Plywood dimensions vary by region, as different countries have their own standards and preferences. Understanding these regional dimensions is critical, especially for projects that involve sourcing materials internationally or adhering to local building codes.       Indian Common Plywood Sizes According to "Indian Standard, IS:10701:2012" (Structural Plywood - Specification) and "IS:303:1989" (General Plywood Specification) , the common sizes are: ·  2.4 x 1.2 m (8 x 4 ft) ·  2.4 x 0.9 m (8 x 3 ft) ·  2.1 x 1.2 m (7 x 4 ft) ·  2.1 x 0.900 m (7 x 3 ft) ·  1.8 x 1.2 m (6 x 4 ft) ·  1.8 x 0.9 m (6 x 3 ft) Common thickness: 3mm, 4mm, 6mm, 9mm, 12mm, 15mm, 18mm, 25mm   UK Plywood Dimensions According to the british standards BS EN 315, common sizes of plywood are as follows: ·  2.44 x 1.22 m ( 8 x 4 ft )  ·  2.74 x 122 m ( 9 x 4 ft )  ·  3.05 x 1.22 m ( 10 x 4 ft )  ·  2.40 x 1.22 m ( 7.8 x 4 ft ) ·  2.50 x 1.22 m ( 8.2 x 4 ft ) Common thickness: 3mm, 6mm, 9mm, 12mm, 15mm, 18mm, 21mm, 24mm, 25mm   Plywood Sizes In The Philippines According to the standards of the Philippine Board of Standards (BPS) , the common sizes of plywood are as follows: ·  8x4 ft (2440mm x 1220mm) ·  7x4 ft (2135mm x 1220mm) ·  6x4 ft (1830mm x 1220mm) ·  6x3 ft (1830mm x 915mm) Common thickness: 3mm, 4mm, 6mm, 9mm, 12mm, 15mm, 18mm, 25mm     Dimensional Tolerance       The dimensional tolerance of plywood indicates the permissible ranges of deviations during the manufacture of plywood. Tolerance arises in the course of manufacturing since the wood being used is a natural material that can undergo changes in response to environmental vitiants like humidity and temperatureore. An outline of some more commonly spoken about aspects of the plywood dimensional tolerance includes:   Length And Width Tolerance: For standard size plywood (such as 8x4 feet), the tolerance for length and width is generally between ±3 mm and ±5 mm. This means that plywood with a nominal size of 2440 mm X 1220 mm may actually be between 2435 mm and 2445 mm, with a width between 1215 mm and 1225 mm.   Thickness Tolerance: Usually, the range of this tolerance is small, around ±0.5mm to ±1mm. Between 17.5mm and 19mm, for instance, is under consideration when dealing with a nominal plywood measurement of 18mm.   Flatness And Straightness: Flatness and straightness tolerances are assigned to plywood to permit it while still shed light upon the status, therein to make certain that the sheet stays flat and the edges remain straight. These tolerances have, in general, been expressed as deviation per meter in measurements.   National Standards: The National Standards vary beyond borders and applicable jurisdictions. For example: ISO 10983: Plywood standard developed under the authority of the International Organization for Standardization (ISO). BS EN 315: British Standard (BS) dimensional tolerances for plywood. ASTM D1037: American Society for Testing and Materials (ASTM) standard for testing plywood, including dimensional tolerances. PNS: Philippine National Standards (PNS) articulate the dimensional tolerances of plywood.   Manufacturer's Standards: The idea of manufacturer own standards is simple: some manufacturers have their own internal standards; some may exceed national or international standards in an attempt to ensure greater quality.         Tolerances exist to capture the deviations that occur during the manufacturing process; however short, the product must remain effective and usable in the actual clearance. When it comes to buying plywood, understanding the tolerances involved can aid you in planning and executing your projects better.           Plywood Sizes And Prices         Plywood size is directly proportional to price: Size of plywood positively correlates with price. For instance, a standard 4 by 8 ft sheet of plywood may cost $15-$30, whereas an oversized sheet, either 4 by 7 ft or even smaller sized 6 by 4 ft, may generally range from $20 to $40. Thickness of wood also influences pricing,18 mm-thick sheets are way costlier than their 12 mm-thick cousins and are typically pegged from ten to twenty percent extra. The demand, quality of materials, cost of production, as well as other factors also influence price, although size remains variously cited as one of the more prominent determining factors.           How Plywood is Made         In plywood manufacture, high-quality wood is selected for the core material, followed by sawing into thin wood slices or veneers. Nursing by rotary-cutting or slicing produces veneer of varying thicknesses. Following, these veneers dry off to reduce moisture content, and adhesives bond these veneers together layer by layer. The grain direction of each layer of veneer is alternated with subsequent layers: usually perpendicular to the adjacent layers of veneer during lamination to enhance strength and stability. Afterwards, glued plywood is cured and pressed directly or with the help of hot or cold methods. Ultimately, these plywood panels are trimmed to standard size and gone under various surface treatments like sanding or painting to enhance their look and durability. The entire process requires precise control of temperature, humidity and pressure so as to guarantee the quality and service performance of the plywood.           Types Of Plywood Core   There are many types of core materials for plywood. Here are some common types of plywood core materials:   Lumber core: A solid wood core (of solid wood strips or blocks) is generally softwood (like pine) or hardwood-such as eucalyptus. These plywoods, with their solid wood cores, tend to have good structural strength and are used for the bearing of loads. Veneer core: Thin sheets (veneers) of wood are stacked and glued at right angles to the adjacent layers to improve strength and stability. Lightweight and good at resisting bending. MDF core: The core material of MDF core plywood is made from pressed wood fibers with a resin adhesive that has a smooth surface and has good processing properties. Particle board core: The core is made from pressed wood chips with resin binder, which gives the core improved stability and reduced likelihood of warping, better than other materials.             How Heavy Is A Sheet Of Plywood   Here are some approximate weights for a standard 4x8 foot sheet:   1/4 inch (6mm): Around 22-24 pounds (10-11 kg) 1/2 inch (12mm): About 40-45 pounds (18-20 kg) 3/4 inch (19mm): Approximately 60-65 pounds (27-29 kg)   Keep in mind: Wood Species: Different species of wood have different densities. For example, birch plywood is generally denser than pine plywood. Moisture Content: Plywood can absorb moisture, which increases its weight. Construction: The way the plywood is constructed (the number of plies, the type of glue, etc.) can affect its weight.             Summarize         Recognizing the attributes of plywood that relate to size, thickness, core material, and geographical variables will serve as a guideline for selecting the right plywood for any specific project. In determining the best plywood for your particular project, it would be prudent to consider its intended usage; whether for structural or decorative purposes, budget constraints, environmental factors, and desired aesthetics. The better informed you are regarding nominal versus actual thickness, plywood tolerances, and core material types, the more likely that your plywood will be durable, cost-effective, and aesthetically pleasing. Proper planning and selection will ultimately increase the success of your project and save time and resources.       FAQ   Why is 3/4-inch plywood actually less than 3/4-inch thick? This is because the thickness of plywood is usually marked as a nominal thickness, and the actual thickness is slightly thinner. During the manufacturing process, the surface of the plywood is sanded, which slightly reduces the final thickness. The actual thickness of 3/4-inch plywood is usually about 18 mm.   How to choose the right plywood for your project? When choosing plywood, you need to consider the purpose of the project, budget, environmental factors, and aesthetic needs. If it is a structural project, it is recommended to choose a thicker plywood, such as 3/4-inch or 18-mm thickness, and choose a core material with good load-bearing capacity; if it is a decorative project, you may need to choose an MDF core plywood with a smooth surface.   How to avoid the problem of inappropriate plywood size? Before purchasing plywood, make sure to measure the required dimensions accurately and consider the tolerances of the plywood. Especially in projects that require precise dimensions, it is best to confirm the actual thickness before purchase and test and adjust in advance during construction.
