Vietnam plywood types used in concrete making and associated construction projects
Formwork application necessitates formwork plywood panels with three or more layers of film-faced or uncoated film. The bending strength and durability of wood sheets in concrete applications are affected by the features and characteristics of the sheets. These properties not only impact the sheet's price, but also how many times it may be used in concrete forming. The lower the cost per use is, the more times a sheet can be reused before losing some of its qualities and performance.
Raw materials of formwork plywood
A variety of materials are utilised by plywood makers around the world in addition to the more traditional species of acacia, eucalyptus, birch, or poplar (or even pine).
A lot depends on what kind of wood you choose and how much you pay attention to what kind of coating you use on the plywood surface: the film you put on top of it. Wood's innate ability to absorb moisture creates the sponge look. As a result, the panels move, which alters the material's weight and mechanical properties, reducing its lifespan.
The uniformity of the concrete's quality and the project's cost efficiency will be determined by choosing the proper type of coating while taking the application into consideration.
The best plywood film materials include a variety of options such
- Coating with urea-melamine resin
- Covered in a plastic film
- Film covering
- Fiber-reinforced synthetic resin covering
Plywood alternatives include complete plastic, plastic coated with increased bending stiffness, and aluminum.
The kind of plywood sheets you need depends on what you'll be using them for.
For commercial, residential, and high-rise construction projects, the type of plywood panels to be ordered is generally determined by the slab and wall formwork being utilised. Plywood used in slab and wall formwork can wear out more quickly due to the extensive use of floor surfaces or the frequent re-use cycles required for wall formwork. As a result, if you want to reduce your cost per usage, you should invest in higher-quality panels that will last longer. The more times the plywood is repurposed, the greater the impact on the structural needs of the resultant concrete surface.
The construction process has a significant impact on the choice of plywood sheets while working on large-scale infrastructure projects like tunnels and bridges. Plywood must be sturdy enough to be reused many times when continuous flow is necessary and many concrete pours are anticipated (often more than 50).
Because of all of the pouring processes and considerable intervals between them, bridge construction necessitates extra strong reinforcement. It's critical to account for plywood shrinkage and avoid using plywood in a way that compromises the concrete's quality or extends the project's time.

Loose application and construction works supporting
Some parts of the construction endeavour, such as the use of plywood by the workers, are easy to miss. In the real world, plywood is frequently used for less complex tasks like setting up a construction site - temporary structures that aid with the building's construction, site gates, dust barriers that protect or separate different parts of the project - as well as many other supporting roles.
It's not always easy to build walls and structures since variable shapes, infill regions, and box outs complicate things. Using the same expensive plywood sheets for loose application as for concrete pouring is not cost-effective. Plywood sheets without a finish or with only the most basic qualities are ideal for this application.
If you plan ahead of time, you'll be able to get a better deal on plywood when the time comes.
Surface finish of the finished concrete that you're going for
Because of this, plywood used in architecturally demanding building projects would have to have certain properties, such as resistance to scratches and vibrations, big panel size, and a smooth or patterned surface. The plywood sheets must have specified qualities if a paint or plaster is to be applied to smooth concrete.
Plywood made for fair-faced concrete surfaces might be a good option if the concrete face is to be left untouched.
Organizing plywood sheets into different types
Plywood sheets are available in a wide range of sizes, grades, and classifications. The most cost-effective way to buy plywood is to combine several types of it.
Classification based on the number of times something has been used (guide value):
- a maximum of two iterations
- 2-10 iterations are required.
- 10 - 50 iterations
- 50-100 recurrences are required.
- Over a hundred iterations
Categorization by classes:
Top - optimum features or special case use, up to 100 use cycles, higher price range. Take the following examples: Pro Form and Top Form.
In order to organize your order in the most cost-effective manner, you must consider logistics and purchasing alternatives while selecting the proper plywood. You may be sure in the success of your construction project if you engage with a supplier who sees plywood as an integral component of the overall picture and offers a comprehensive solution for purchasing or renting plywood material and formwork, logistics, and engineering expertise.
