140×19 Merbau Decking

140×19 Merbau decking has become one of the most trusted choices in Australia thanks to its durability, natural beauty, and ability to create a premium outdoor look. With its wider 140mm board profile, it delivers a sleek, modern finish while reducing the number of joins across the deck.

Merbau is a dense, strong hardwood known for its excellent resistance to decay, termites, and harsh weather. Its rich reddish-brown colour enhances the aesthetics of any outdoor space and can be maintained with oiling or allowed to gracefully weather into a silver-grey tone.

Because Merbau is naturally high in tannins, proper preparation such as washing and sealing helps prevent staining during installation. The board size also requires correct spacing, ventilation, and pre-drilling due to its density. When installed with quality fasteners and maintained regularly, 140×19 Merbau decking can last for decades.

Whether you’re building a new deck, upgrading an existing area, or designing a luxurious outdoor entertainment space, 140×19 Merbau decking offers strength, style, and long-term value.
