What Is Plywood and What Is It Used For?

Plywood is one of the most versatile building materials available today. Whether you’re renovating your home, working on a DIY project, or tackling a larger construction job, it offers an ideal mix of strength, stability, and affordability.
In this guide, we’ll explain what plywood is, how it’s made, and the many ways you can use it around your home, garden, or on site.

What Is Plywood?

Plywood is an engineered wood sheet made from thin layers of natural timber, called veneers. These layers are glued together with each grain running at a 90-degree angle to the previous one.
This cross-graining method gives several advantages:

  • Excellent strength and load-bearing ability

  • Reduced risk of warping or twisting

  • Enhanced stability compared with solid wood

It’s this construction that makes plywood dependable for both structural and decorative use.

How Plywood Is Made

The manufacturing process involves:

  1. Peeling logs into thin veneers

  2. Drying the veneers to remove moisture

  3. Layering and gluing them with resin adhesive

  4. Pressing under heat and pressure to create a solid sheet

  5. Sanding the surface smooth for painting or finishing

Different adhesives and numbers of layers create different grades of plywood — some ideal for indoor projects, others designed to handle moisture and outdoor use.

Types of Plywood

Plywood isn’t one-size-fits-all. Clarke Fencing supplies several high-quality options for different applications.

Hardwood Plywood (Class 2)

Made from durable hardwood veneers such as birch, hardwood plywood is ideal for:

  • Furniture making

  • Flooring

  • Shelving

  • Joinery

It has a smooth finish, strong structure, and accepts paint or stain extremely well.

Structural Plywood

Also known as standard plywood, this grade is built for strength and load-bearing performance.
Ideal for:

  • Roof decking

  • Flooring

  • Wall sheathing

Our 18mm Structural Class 2 Plywood (PINEX) is a popular choice for general construction.

Mesh-Faced Rhino Board

A specialist anti-slip plywood sheet featuring a resin-coated mesh face.
Best for:

  • Vans and trailer floors

  • Platforms and ramps

  • Industrial environments

It provides excellent grip and durability under heavy use.

OSB (Sterling Board)

While not technically plywood, OSB3 is widely used in similar applications.
It’s ideal for:

  • Sheathing

  • Subfloors

  • Roofing

Its strength-to-weight ratio makes it a favourite in construction. We sell both 11mm OSB3 and 18mm OSB3

Common Plywood Uses

Its versatility makes it suitable for almost every indoor project.

Why Choose Plywood?

It offers several advantages:

  • Strong and stable due to its cross-grained construction

  • More cost-effective than solid wood

  • Lightweight and easy to work with

  • Suitable for structural, decorative, and DIY tasks

  • Efficient use of timber resources, making it more environmentally friendly

With proper sealing and installation, it can last for decades.
