Softwood plywood is a type of plywood made from softwood tree species such as pine, fir, spruce, or cedar. It is commonly used in construction, furniture making, and structural applications due to its strength, affordability, and ease of use.
Key Characteristics of Softwood Plywood
Made from Softwood Species
- Typically constructed using pine, fir, spruce, cedar, or redwood.
- Some varieties use a mix of softwood veneers for added strength.
Strong and Durable
- While classified as “softwood,” softwood plywood is structurally strong and commonly used in building projects.
Comes in Multiple Grades
- A-grade: Smooth surface, minimal knots, suitable for visible applications.
- B-grade: Some small knots, suitable for furniture and general use.
- C & D-grade: More defects, used for construction and structural support.
Common Sheet Sizes
- Standard size: 4×8 feet (1.22m x 2.44m).
- Available in thicknesses ranging from 1/8 inch to 1 inch.
Common Uses of Softwood Plywood
Construction & Framing
- Used for subfloors, wall sheathing, and roofing in residential and commercial buildings.
Furniture & Cabinetry
- Used in tabletops, shelving, cabinets, and interior furniture where durability is required.
Outdoor & Marine Applications
- Pressure-treated softwood plywood is used for outdoor projects such as decks, fences, and sheds.
- Marine-grade softwood plywood is ideal for boats and docks.
Packaging & Crating
- Commonly used for making wooden crates, pallets, and shipping containers due to its lightweight and affordability.
Advantages of Softwood Plywood
✅ Strong and Lightweight – Offers a good balance of durability and weight.

Disadvantages of Softwood Plywood
❌ Less Aesthetic – Compared to hardwood plywood, softwood plywood has more knots and surface defects.
❌ Prone to Moisture Damage – Unless treated or sealed, it can warp or rot when exposed to moisture.
❌ Lower Density – Not as dense or impact-resistant as hardwood plywood.
How is Softwood Plywood Different from Hardwood Plywood?
| Feature | Softwood Plywood | Hardwood Plywood |
|---|---|---|
| Wood Type | Pine, fir, spruce, cedar | Oak, maple, birch, mahogany |
| Strength | Strong but lighter | Stronger and more impact-resistant |
| Uses | Construction, subfloors, furniture | High-end furniture, cabinetry, flooring |
| Surface | May have knots and imperfections | Smooth, fine grain with fewer defects |
| Moisture Resistance | Requires sealing or treatment | Naturally more resistant to moisture |
How to Protect Softwood Plywood?
To make softwood plywood last longer, follow these steps:
- Seal the Surface – Apply varnish, polyurethane, or a wood sealer to prevent moisture damage.
- Use Pressure-Treated Plywood – Ideal for outdoor projects.
- Paint or Stain – Adds protection against UV rays, moisture, and wear.
- Store Properly – Keep in a dry place, away from direct ground contact to avoid warping.
Conclusion
Softwood plywood is a strong, versatile, and budget-friendly material used in construction, furniture, and outdoor projects. Although it needs sealing or treatment to resist moisture, its lightweight design and durability make it a popular choice.
