5/4x6 Ipe Pre-Grooved Decking

A 5/4x6 Ipe board weighs approximately 2.67 lbs per linear foot. Ipe has a density of about 69 lbs/ft³, making it one of the densest commercially available hardwoods. A 12-foot 5/4x6 Ipe board weighs approximately 32 lbs. Always factor weight into your structural and shipping calculations.

5/4x6 Ipe decking has an expected service life of up to 75+ years when properly installed. This is 3-5× longer than pressure-treated pine and 2-3× longer than cedar. Ipe achieves this exceptional longevity through its 3,680 Janka hardness and Class 1 durability rating, providing built-in resistance to rot, decay, insects, and fungal growth without chemical preservatives.

5/4x6 Ipe 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, Ipe's up to 75+-year service life makes the lifetime cost per year significantly lower.

Yes — 5/4x6 Ipe wood decking outperforms composite in hardness (3,680 vs ~200 Janka), lifespan (up to 75+ years vs 25-30 years), and heat resistance. Unlike composites, Ipe won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Ipe wood decking costs less over its much longer lifetime. Composites do offer lower upfront maintenance, but Ipe's natural beauty and durability make it the superior long-term investment.

Ipe is widely considered one of the best woods for 5/4x6 decking boards. With a 3,680 Janka hardness rating, Class A fire-rated certification, and up to 75+-year lifespan, Ipe (Brazilian Walnut) outperforms nearly every other commercially available wood species. Other excellent options include Cumaru (Brazilian Teak) and Massaranduba (Brazilian Redwood), but Ipe remains the industry benchmark for premium outdoor hardwood applications.

Ipe 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.

Ipe is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Ipe is too hard for direct screwing. (2) Use only 305 or 316 stainless steel fasteners — standard hardware will corrode and stain. (3) This pre-grooved profile uses hidden clip systems like Ipe Clip® for a screw-free surface. (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 5/4x6 Ipe board has actual finished dimensions of 1" × 5.5" (25.4 x 139.7 mm). The "5/4x6" 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 (1" × 5.5") when calculating material quantities and coverage for your project.

We responsibly, legally, and ethically source all our Ipe. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Note: We are not FSC certified. Ipe trees grow naturally in diverse tropical forests and regenerate well under managed harvest. The extremely long lifespan (up to 75+ years) means fewer replacements compared to softwood or composite alternatives, reducing long-term environmental impact.
