Name: China DADIW ISA 21mm Darkbrown Film Faced Plywood Manufacturers Factory - Dadi Wood
Brand: Dadi
SKU: 309956503

DADIW ISA 21mm Dark-Brown Film-Faced Plywood is manufactured using a high-quality composite core and phenolic film, bonded under high temperature and pressure. Its thickened design significantly enhances structural rigidity and load-bearing capacity, ensuring stability against the high lateral pressure exerted during large-volume concrete pouring. The panel surface is flat and smooth, delivering a high-quality "fair-faced" concrete finish upon formwork removal-eliminating the need for plastering.DADIW ISA 21mm Dark-Brown Film-Faced Plywood is suitable for heavy-duty engineering projects such as bridges, dams, and nuclear power plants.

Product Features

Superior Load-Bearing Capacity

The 21mm thickness offers significantly better rigidity than thinner panels. During formwork setup, the spacing between vertical supports can be increased, reducing the amount of scaffolding required. Even under the high lateral pressure of pouring large beams or thick walls, the panels resist bulging and warping, ensuring structural stability.

Greater Construction Stability

The robust 21mm panels provide excellent structural integrity once assembled. They do not vibrate or shift when workers tie rebar or walk on the surface, nor do they easily deform or move during concrete pouring. This results in precise structural dimensions and flat wall surfaces after demolding.

Higher Efficiency

With standard large panel sizes, fewer panels are needed to cover a wall, resulting in fewer joints and faster formwork assembly. They can be sawn, nailed, and drilled, allowing for on-site cutting as needed. They are far more convenient than steel formwork-requiring no cranes and allowing workers to handle installation independently.

Lower Overall Cost

Although the unit price is slightly higher than standard formwork, the product offers 2–3 times the number of reuses, resulting in a lower cost per use. After formwork removal, the concrete surface is smooth and requires no plastering or leveling, resulting in savings on both labor and material costs.

Company Advantages

Located in Langfang, Hebei, Dadi Wood Industry operates a 300,000 m² production base equipped with 12 production lines and 60 hot presses, achieving a daily output of 50,000–60,000 sheets of high-quality film-faced plywood. The company holds dual ISO certifications, possesses 10 utility model patents, and participates in the revision of national standards. Its brands-DADIWISA and DADIVISA-have been utilized in key national projects such as the Bird's Nest (National Stadium), Daxing Airport, and the Hong Kong-Zhuhai-Macao Bridge, and are exported to markets in North America, Southeast Asia, Africa, and Russia.

FAQ

Q: For what types of projects is 21mm formwork primarily used?

A: It is mainly used for high-load formwork applications, such as the construction of heavy-duty walls, floor slabs, and large beams, as well as projects requiring high formwork stability, including bridges, dams, nuclear power plants, and the core tubes of high-rise buildings.

Q: How should DADIWISA 21mm Dark Brown Film-Faced Plywood be stored?

A: It is recommended to store the panels flat in a dry, level area, using supports at the bottom to prevent moisture absorption. Avoid prolonged exposure to dampness, rain, or direct sunlight to ensure the panels maintain their performance characteristics.
