Timber Decking Board

MGM Timber stocks timber decking boards, an affordable and sustainable choice for your landscaping project.

Timber decking offers a natural aesthetic that instantly improves any outdoor space. It's rot-resistant and durable, designed to provide long-lasting performance with minimal maintenance.

Timber can be painted or stained to suit your personal style. All our timber decking boards and components are sawn, dried, and machined on-site here in the UK. This allows us to maintain complete control over the manufacturing process and ensure rigorous quality control.

With a wide variety of lengths and section sizes available to buy, you can often construct your decking project without the need for cutting, making installation even simpler.

OUR TIMBER DECKING SIZES

We stock industry-standard 28x144mm timber decking boards. These are made from certified redwood—specifically slow-growing red pine, which is known for being the best in the market for durability.

All our boards are grooved, meaning you will always have a valid source of grip in your deck. We also have anti-slip additional grip options, if you need that extra bit of support. These are especially good for commercial properties with high foot traffic.

We are fully sustainable in our sourcing, and our products carry either FSC or PEFC certification, ensuring responsible forestry practices.

Where possible, we supply requested lengths, and if unavailable, we provide the nearest alternative to match your total meterage.

FAQS ABOUT TIMBER DECKING

WHAT TIMBER DO I USE FOR A DECKING FRAME?

The best timber is carcassing treated as this can be in ground contact. However, most people fit the frame to posts in the ground so the frame can be off the ground. If the frame is off the ground, C16 timbers can be used.

WHAT SIZE TIMBER FOR A DECKING FRAME?

Size depends on what height you have to work with. Our standard decking is 144mm so the 45x145 C16 works well, or the 47x150mm carcassing as a board of decking will cover this. But can use 3x2, 4x2, 5x2 or 6x2 depending on the specific project.

HOW LONG DOES TIMBER DECKING LAST?

The average lifespan of timber decking in the UK is 10 – 15 years, but it can last longer than this if it is frequently maintained. Proper installation, with ventilation underneath the decking and the correct spacing between boards is essential as it helps prevent moisture build up and rot. Annual cleaning, treatment and staining will help your decking last for a long period of time.
