Double Stripe Waterproof Outdoor Bamboo Flooring

Solid Carbonized Anti-slip Fast Drainage Deck

Density 1.15-1.25 g/cm³ Janka ≥3,000 lbf COF ≥0.75 wet

01 Product Overview

Double stripe waterproof outdoor bamboo flooring is engineered for exterior environments requiring rapid water drainage and slip resistance. The manufacturing process utilizes strand woven bamboo technology with carbonization at 180-200°C. The surface features two parallel precision-milled channels running along the board length, each measuring 8mm width and 4mm depth. These dual channels create a fast drainage system that evacuates water from the walking surface. Material density ranges from 1.15 g/cm³ to 1.25 g/cm³. The carbonized structure reduces equilibrium moisture content to 8-12%, providing resistance to decay organisms and dimensional movement. The double stripe geometry increases surface friction in wet conditions while maintaining a comfortable underfoot texture. This decking is specifically developed for pool surrounds, exterior walkways, and commercial terraces where rapid water runoff is required.

Core Properties

Double Stripe Drainage

Two parallel channels measuring 8mm width and 4mm depth create rapid water evacuation. Prevents standing water accumulation and reduces slip hazards.

Solid Carbonized Construction

Strand woven bamboo with phenolic resin. Carbonization at 180-200°C removes organic compounds, reducing moisture content to 8-12%.

Anti-Slip Surface

Double stripe geometry increases friction coefficient in wet conditions. Wet COF exceeding 0.75 per ASTM D2394.

High Density Durability

Material density of 1.15-1.25 g/cm³ and Janka hardness exceeding 3,000 lbf resist indentation and surface wear.

Q

Frequently Asked Questions

01 How does the double stripe system improve drainage compared to single groove patterns? +

The double stripe system features two parallel channels measuring 8mm width and 4mm depth, creating twice the water evacuation capacity of single groove designs. The dual channels ensure rapid water channeling off the walking surface even during heavy rainfall. The 4mm depth provides sufficient volume capacity for continuous water flow without overflow. The stripe orientation along the board length directs water toward the deck edge, preventing puddling and reducing slip hazards.

02 What is the expected slip resistance performance of the double stripe surface? +

Testing under ASTM D2394 shows wet coefficient of friction values exceeding 0.75, exceeding the recommended minimum of 0.6 for pedestrian surfaces in wet conditions. The double stripe geometry provides multiple contact points for footwear, increasing surface traction. The stripe edges create mechanical grip without aggressive texture that could cause discomfort underfoot. The slip resistance is inherent to the surface profile and does not rely on applied coatings.

03 What maintenance procedures are recommended for the double stripe decking? +

Regular maintenance includes quarterly cleaning with a soft-bristle brush and neutral pH detergent to remove debris from the stripe channels. The 8mm wide channels allow for effective cleaning using standard deck brushes. Pressure washing at 5-7 MPa with 300mm standoff distance is recommended for deep cleaning. Application of water-based outdoor oil every 12-24 months preserves surface appearance and water repellency.

04 Is this decking suitable for high-traffic commercial applications? +

Yes, the decking meets performance requirements for commercial applications with moderate to heavy foot traffic. The strand woven construction at 1.15-1.25 g/cm³ density provides resistance to indentation and surface wear. The carbonized material achieves Janka hardness exceeding 3,000 lbf. The double stripe profile is appropriate for outdoor restaurant terraces, pool decks, and public walkways. Installation on joists at 400mm maximum centers ensures load-bearing capacity.
