H20 Timber Beam Factory - Dongstar® - China MDO/HDO Plywood Manufacturer
Dongstar MDO Plywood and HDO Plywood are engineered overlay panels designed for appliQcations where surface durability, moisture resistance, dimensional stability, and repeated reuse matter.
MDO (Medium Density Overlay) and HDO (High Density Overlay) plywood combine a strong plywood core with a resin-impregnated overlay surface. Compared with standard film faced plywood, the overlay provides a more uniform and durable working surface for concrete formwork, industrial applications, transportation, and other demanding projects.
Dongstar supplies MDO and HDO Plywood for contractors, formwork companies, wholesalers, importers, distributors, and large-volume project buyers worldwide.
MDO/HDO Plywood Key Benefits
Durable Resin Overlay
The resin-impregnated surface provides better resistance to moisture, abrasion, concrete adhesion, and jobsite wear than conventional plywood surfaces.
Smooth Concrete Finish
The uniform overlay helps produce a smoother concrete surface and can reduce the need for extensive finishing work.
Excellent Moisture Resistance
MDO and HDO Plywood are designed for demanding environments where conventional plywood may experience premature surface deterioration.
High Reusability
With proper handling, cleaning, storage, and edge protection, overlay plywood can be reused through multiple formwork cycles.
Stable Plywood Core
A carefully selected plywood core provides the strength and dimensional stability required for professional construction applications.
Easy Processing
Panels can be cut, drilled, nailed, and installed using standard woodworking and construction equipment.
MDO Plywood
MDO Plywood uses a medium-density resin overlay bonded to a structural plywood core.
It provides a useful balance between surface performance, durability, and cost, making it suitable for contractors and distributors looking for reliable overlay plywood without the higher cost of HDO.
Typical MDO Plywood Applications
- Concrete formwork
- Wall formwork
- Slab formwork
- Column formwork
- Construction panels
- Industrial applications
- Transportation applications
- Exterior construction
HDO Plywood
HDO Plywood features a high-density resin overlay designed for more demanding applications.
Its dense, durable surface provides excellent resistance to moisture, abrasion, concrete adhesion, and repeated handling.
For contractors operating large formwork fleets, the higher initial cost of HDO Plywood can be justified when long service life and high reuse rates are important.
Typical HDO Plywood Applications
- Heavy-duty concrete formwork
- Bridge construction
- Tunnel projects
- High-rise construction
- Infrastructure projects
- Industrial formwork
- Repeated-use formwork systems
- Transportation and industrial applications
MDO / HDO Plywood for Concrete Formwork
For concrete contractors, the most important factors are not simply plywood thickness or price.
A suitable formwork panel needs to provide:
- Adequate structural strength
- Reliable moisture resistance
- A durable working surface
- Good concrete release
- Dimensional stability
- Consistent thickness
- Repeatable performance
Dongstar MDO and HDO Plywood are manufactured with these requirements in mind.
For projects involving a high number of concrete pours, buyers should evaluate total cost per reuse cycle, rather than comparing only the initial sheet price.

FAQ
1. What is MDO Plywood?
MDO Plywood is plywood covered with a resin-impregnated medium-density overlay. It provides a smooth, durable, and moisture-resistant surface for construction and other demanding applications.
2. What is HDO Plywood?
HDO Plywood is plywood manufactured with a high-density resin overlay. It offers a harder and more durable surface than MDO and is commonly selected for heavy-duty and repeated-use applications.
3. What is the difference between MDO and HDO Plywood?
The primary difference is the density and performance of the overlay. MDO provides a balance between durability and cost, while HDO provides a denser, harder surface for more demanding and repeated-use applications.
4. Is MDO Plywood waterproof?
MDO plywood provides high moisture resistance, particularly when manufactured with a suitable waterproof adhesive and properly sealed edges. It should not, however, be treated as permanently waterproof under every environmental condition.
5. Is HDO Plywood suitable for concrete formwork?
Yes. HDO Plywood is widely used where a durable, smooth, moisture-resistant surface and repeated formwork use are required.
6. Can MDO and HDO Plywood be reused?
Yes. Reuse depends on panel construction, concrete pressure, handling, cleaning, storage, edge protection, and jobsite conditions.
7. Can Dongstar manufacture customized MDO / HDO Plywood?
Yes. Customized dimensions, core construction, overlay specifications, colors, edge treatment, packaging, and branding can be discussed for bulk orders.
