Multi Shades Carbonized Large Channel Strand Woven Bamboo Flooring

Outdoor Use · Wear Resistant · Easy To Clean

Product Overview

Multi shades carbonized large channel bamboo flooring is engineered for outdoor applications requiring both visual variation and functional performance. The manufacturing process combines strand woven bamboo technology with a multi-tone carbonization technique, producing boards with natural color gradations ranging from light amber to deep walnut across individual planks. The large channel surface profile features precision-milled grooves measuring 8mm width and 3mm depth, spaced at 40mm intervals across the board width. These channels facilitate water drainage and debris evacuation from the walking surface. Material density ranges from 1.15 g/cm³ to 1.25 g/cm³. The carbonization process at 180-200°C removes organic compounds and reduces equilibrium moisture content to 8-12%. The multi-shade effect is achieved through controlled thermal exposure during the carbonization stage, creating natural color variation without artificial staining or pigment addition.

Core Properties

Multi-Shade Visual Profile

Controlled thermal exposure during carbonization creates natural color gradations from light amber to deep walnut across individual planks. The multi-tone effect provides visual depth without artificial pigments or surface staining.

Large Channel Drainage

Grooves measuring 8mm width and 3mm depth at 40mm spacing facilitate water drainage and debris evacuation. The channel geometry prevents standing water accumulation on the walking surface.

Carbonized Durability

Thermal modification at 180-200°C removes hemicellulose and starches, reducing equilibrium moisture content to 8-12%. This process provides resistance to decay organisms and dimensional movement.

Easy Cleaning Surface

The large channel profile with smooth channel walls allows for efficient cleaning. Debris does not lodge in narrow grooves. Standard deck cleaning with brush or pressure washing removes surface deposits.

Frequently Asked Questions

01 How does the multi-shade color variation occur in the bamboo flooring? +

The multi-shade effect is achieved through controlled thermal exposure during the carbonization stage at 180-200°C. Different sections of the bamboo fiber receive slightly different heat exposure, creating natural color gradations from light amber to deep walnut. This variation is inherent to the material and does not use artificial stains or pigments. Each board exhibits individual color characteristics while maintaining the overall visual coherence of the floor assembly. The color variation is sealed within the board thickness and does not wear off with use.

02 What are the advantages of the large channel profile over smaller groove patterns? +

The large channel profile with 8mm width and 3mm depth provides three functional benefits compared to smaller groove patterns. First, the wider channels allow for more efficient water drainage, reducing standing water on the deck surface. Second, the channel geometry prevents debris trapping, as leaves and dirt do not lodge in narrow gaps. Third, the large channels are easier to clean using standard deck brushes or pressure washing equipment. The channel spacing at 40mm intervals balances drainage performance with walking surface comfort.

03 What maintenance is required for the multi-shade carbonized bamboo flooring? +

Regular maintenance includes quarterly cleaning with a soft-bristle brush and neutral pH detergent to remove surface debris from the channel profile. Annual 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 color depth and water repellency. The multi-shade color profile does not require color-matching treatments, as the natural variation conceals minor surface scuffs. Fastener inspection should be performed annually to maintain structural integrity.

04 Is the multi-shade carbonized bamboo flooring suitable for high-traffic commercial applications? +

The flooring meets the 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, comparable to the hardest tropical hardwoods. The large channel profile is appropriate for outdoor restaurant terraces and public deck areas. Installation on joists at 400mm maximum centers ensures load-bearing capacity for commercial occupancy loads.
