1x6 Red Balau Tongue & Groove Decking — Frequently Asked Questions

A 1x6 Red Balau board weighs approximately 2.01 lbs per linear foot. Red Balau has a density of about 59 lbs/ft³, making it one of the densest commercially available hardwoods. A 12-foot 1x6 Red Balau board weighs approximately 20 lbs. Always factor weight into your structural and shipping calculations.

1x6 Red Balau decking has an expected service life of up to 40+ years when properly installed. This is 3-5× longer than pressure-treated pine and 2-3× longer than cedar. Red Balau achieves this exceptional longevity through its 1,580 Janka hardness and Class 1 durability rating, providing built-in resistance to rot, decay, insects, and fungal growth without chemical preservatives.

1x6 Red Balau decking pricing varies by profile, grade, and board length. Select and Better grade boards typically range from $4-$12 per linear foot before shipping. While the upfront cost is higher than pressure-treated lumber, Red Balau's up to 40+-year service life makes the lifetime cost per year significantly lower. Use the configurator above for exact pricing, or request a custom quote for large orders.

Yes — 1x6 Red Balau wood decking outperforms composite in hardness (1,580 vs ~200 Janka), lifespan (up to 40+ years vs 25-30 years), and heat resistance. Unlike composites, Red Balau won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Red Balau wood decking costs less over its much longer lifetime. Composites do offer lower upfront maintenance, but Red Balau's natural beauty and durability make it the superior long-term investment.

Red Balau is widely considered one of the best woods for 1x6 decking boards. With a 1,580 Janka hardness rating, Class A fire-rated certification, and up to 40+-year lifespan, Red Balau (Bangkirai) outperforms nearly every other commercially available wood species. Other excellent options include Cumaru (Brazilian Teak) and Massaranduba (Brazilian Redwood), but Red Balau remains the industry benchmark for premium outdoor hardwood applications.

Red Balau requires minimal maintenance. Without treatment, it naturally weathers to an elegant silver-gray patina over 6-12 months. To maintain the original warm brown color, apply a UV-inhibiting penetrating oil (like Ipe Oil or Penofin) once or twice annually. Cleaning involves periodic washing with a mild soap solution. No sanding, staining, or sealing is required for structural durability.

Red Balau is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Red Balau is too hard for direct screwing. (2) Use only 305 or 316 stainless steel fasteners — standard hardware will corrode and stain. (3) Face-screw with stainless steel trim-head screws. (4) Allow boards to acclimate on-site for 5-7 days before installation. A compound miter saw with a carbide-tipped blade is recommended.

A nominal 1x6 Red Balau board has actual finished dimensions of 0.75" × 5.5" (19.0 x 139.7 mm). The "1x6" is the nominal (rough-cut) size — after kiln drying and precision surfacing, all hardwood lumber finishes slightly smaller. This is standard across the lumber industry, similar to how a nominal 2×4 softwood measures 1.5" × 3.5". Always use the actual dimensions (0.75" × 5.5") when calculating material quantities and coverage for your project.

We responsibly, legally, and ethically source all our Red Balau. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Note: We are not FSC certified. Red Balau trees grow naturally in diverse tropical forests and regenerate well under managed harvest. The extremely long lifespan (up to 40+ years) means fewer replacements compared to softwood or composite alternatives, reducing long-term environmental impact.

Why Choose 1x6 Red Balau Wood for Your Deck?

Red Balau decking delivers a naturally slip-resistant, splinter-free surface that stays cool underfoot even in direct sunlight. Unlike composite or pressure-treated alternatives, it never fades to a dull gray unless you want the natural silver patina look.

Red Balau carries a Class A - Low flame spread, making it suitable for wildfire-prone regions where code-compliant materials are required.

The 1x6 tongue & groove (T&G) profile features interlocking edges that create a seamless, flush surface with no visible gaps. Ideal for porch ceilings, soffit installations, and covered porch floors.

1x6 Red Balau Decking — Frequently Asked Questions

1x6 Red Balau decking has an expected service life of 40+ years when properly installed and maintained. This is 3-5x longer than pressure-treated pine and 2-3x longer than cedar. Red Balau achieves this exceptional longevity through its natural density (Janka hardness: 1,580 lbf) and Class 1 durability rating, which provide built-in resistance to rot, decay, insects, and fungal growth — all without chemical preservatives.

1x6 tongue & groove Red Balau boards interlock via a milled tongue on one edge and a corresponding groove on the other. Secure each board by blind-nailing through the tongue at a 45° angle using stainless steel ring-shank nails or by face-screwing with countersunk stainless steel screws. Always pre-drill holes in Red Balau to prevent splitting. T&G Red Balau should only be used in covered or semi-protected areas.

1x6 Red Balau decking pricing varies by profile, grade, and board length. 1x6 Tongue & Groove boards in Select and Better grade typically range from $4-$12 per linear foot before shipping.
