Gripdeck Balau Hardwood Decking 21mm
21mm x 145mm Grooved Balau (Bangkirai) Hardwood Decking
Grooved Balau Hardwood Decking is a versatile, durable and visually striking choice for elevating your outdoor space. Manufactured from the renowned hardwood species Bangkirai (Balau), these boards are designed to create a timeless and elegant deck that will perform for many years.
The grooved profile adds a classic hardwood decking look while improving underfoot grip, making it suitable for a wide range of applications such as terraces, balconies, garden decks, commercial walkways and steps.
Bangkirai hardwood is known for its exceptional robustness and durability. Boards are supplied in a rich light brown tone that will gracefully weather to a natural silver grey when exposed to the elements, adding character and depth to your outdoor area over time.
Elevate your outdoor living space with the natural beauty and long-term performance of Grooved Balau Hardwood Decking – a premium hardwood solution that combines aesthetics, strength and longevity.
Natural colour variation: Hardwood decking offers a unique and organic appearance, with boards varying in shade and grain from piece to piece. Within the same deck you may see a mix of deeper browns, warm reds, golden tones and softer greys. This variation is a natural feature of hardwood and helps ensure every deck is truly individual.

Delivery cost is calculated at checkout based on your postcode, product dimensions and order weight.
We will contact you to organise a suitable delivery day for your order. Someone will need to be there to accept and unload the delivery. Please note that drivers will not unload the delivery. Unloading is the responsibility of the customer. You will need suitable manpower or a forklift and must be able to unload your delivery within 20 minutes of the lorry arriving.
- Most vehicles are 18 tonne trucks (similar to a refuse truck). Please ensure access roads are suitable and free from low branches, low bridges or planned roadworks.
- If the delivery address can only accept smaller vehicles, you must inform GripDeck in advance via email. Smaller vehicles are subject to availability and may incur a surcharge.
- For named houses, please provide clear directions or landmarks in the order comments.
- Standard delivery window is 9am–5pm, Monday–Friday. Please ensure someone is available to accept the goods.
- All deliveries are kerbside only. As hardwood decking is too long to pallet truck off the lorry, you will need equipment or labour to offload by hand.

- Drivers are allocated 20 minutes per delivery. If unloading exceeds this, a redelivery charge may apply.
