Merbau Decking - A Class Building Materials

Do you want to revamp your outdoor space? You can try upgrading your backyard with our high-quality Merbau decking. These boards are well-known for their rich brown colour, durability, and natural resistance to termites and rot.

A Class Building Materials is a reliable supplier of hardwood planks in Melbourne. You can use these wooden beams to build:

  • Garden edging

  • Screening

  • Decks

  • Pergolas

  • Flooring

  • Support posts

  • External stairs

  • Fencing and more

Mebau, or Kwila, is a low-maintenance, hard-wearing and long-lasting timber with high tannin content. Due to its strength, the material is used in households, construction, and marine applications. Well-built outdoor Merbau decks can add value to the property and command higher prices. They enhance your backyard, making it more welcoming.

Benefits of Merbau Decking

Merbau timber is one of the top choices for floorboards throughout Melbourne, Victoria. It can withstand wear and tear due to foot traffic as well as support weight. Here are some other reasons why homeowners prefer them:

  1. Highly Durable:

    The material is known for its sturdiness. It has a Class 3 durability rating and can resist cracking, splitting, and shrinkage in extreme climates. Moreover, the natural oils in timber prevent moisture buildup, termite buildup, and fungal rotting.

  2. Long-lasting Performance:

    The life expectancy of Kwila beams ranges between 7 to 15 years above-ground and 5 to 15 years in-ground. Thus, the wood can last a decade before showing decay or rot. They need less frequent replacements and lower maintenance. You can use them for your patio furniture, cabinets, or flooring.

  3. Easy-to-work Material:

    Although strong, Merbau decking timber is easy to work with. The material responds well to hand tools, cuts clean, and glues well. Hence, you can use it for a variety of indoor and garden projects.

  4. Beautiful Look:

    Apart from its strength, many people choose this product for its stunning looks. The deep Merbau decking colours look great on classic furniture and other outdoor structures. Its warm, reddish-brown tone with lighter sapwood creates a striking contrast.

  5. Bushfire Resistant:

    Kwila is classified as a bushfire-resisting timber in Australia. It is a dense hardwood, making it more difficult to ignite fire and spread through the forest. Merbau's natural fire resistance capacity can buy valuable time and offer a layer of protection compared to less resistant materials.

  6. Versatile Product:

    The material is adaptable and can be used indoors and outdoors. Apart from residential decks and flooring, one can find them in construction, shipbuilding, and engineering projects.

  7. Needs Less Maintenance:

    Unlike other hardwood variants, it requires comparatively little maintenance. You can clean it with soapy water and a stiff-bristled brush. In addition, giving a coat of high-quality oil, every 12 months is enough to maintain its beauty.
