What You Need To Know About PAR Timber for Shelving

It usually starts with a simple idea. A bare wall that needs storage. A nook that could work harder. A shelf that should look good and actually hold its weight. That’s where timber choices start to matter more than most people expect.

PAR timber, short for Planed All Round, is often the quiet hero behind shelves that feel solid, look clean, and don’t fight you during installation. Smooth on every side and cut to consistent dimensions, it takes much of the guesswork out of building shelves that sit straight, finish neatly, and stand up to everyday use. It’s why PAR timber is a go-to option for everything from open kitchen shelving to garage storage and home office builds.

Let’s unpack what makes PAR timber ideal for shelving, how to choose the right boards for your space, and how to avoid common mistakes that can shorten a shelf’s lifespan. With BUCO’s range of quality PAR timber and building materials, creating strong, good-looking shelves becomes a straightforward project rather than a frustrating one.

What Is PAR Timber?

PAR timber is wood that has been planed on all four sides, resulting in a smooth, uniform finish. Unlike rough-sawn timber, which may have uneven surfaces and require significant sanding, PAR timber is ready to work with straight from the store. This makes it ideal for projects like shelving, where a clean, even surface is crucial for both appearance and stability. By using PAR timber, builders and DIY enthusiasts can save time on preparation while achieving professional-looking results.

Why Use PAR Timber for Shelving?

PAR timber offers several advantages that make it perfect for shelving projects:

Smooth, Ready-to-Finish Surface: No heavy sanding is needed before painting, staining, or sealing.

Consistent Sizing: Boards have uniform dimensions, ensuring accurate fits and clean lines.

Aesthetic Appeal: The smooth surface and precise edges create professional-looking shelves, ideal for open shelving designs.

Load-Bearing Capability: When the correct thickness and width are selected, PAR timber can support heavy items reliably.

Minimal Prep Work: Reduced finishing work allows projects to progress faster without compromising quality.

BUCO’s building materials range provides timber that meets these requirements, making it simple to start your shelving project with confidence.

h2>Choosing the Right Timber for Shelving Selecting the right timber ensures your shelves are both functional and attractive. Consider these factors:

Dimensions: Thickness, width, and length affect load capacity and fit.

Wood Species: Pine is popular for indoor shelves, while hardwoods offer added strength.

Indoor vs Outdoor Use: Outdoor shelving requires timber that can handle moisture and changing weather.

Weight Capacity: Ensure boards are strong enough for books, décor, or kitchenware. PAR timber is ideal for achieving a balance between strength and visual appeal, allowing for sturdy, elegant shelving designs.

How to Select the Right PAR Timber Board

To get the most from your PAR timber, pay attention to:

Board Dimensions: Understand length, width, and thickness to match your design plan.

Grades and Quality: Look for straight boards with minimal knots and even surfaces.

Moisture Content: Ensure timber is dry to prevent warping or sagging after installation.

Board Thickness: Heavier loads require thicker, wider boards for long-term stability. For high-quality, ready-to-use options, consider BUCO’s exterior pine PAR timber that’s ideal for shelving and other structural uses.
