The Ultimate Guide To Formwork Plywood

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.

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.

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.
