5. Why Gray Wood-Grain Finish?
The gray color combined with realistic wood texture offers distinct advantages for modern patio design.

Aesthetic Benefits
Aspect    Advantage
Modern Appearance    Gray complements contemporary architecture; cooler tone than brown wood
Hides Dirt    Gray naturally conceals dust, pollen, and foot traffic marks
UV-Stable    Gray pigments maintain color longer than darker browns
Versatile    Pairs with any outdoor furniture color (white, black, natural wood, bright accents)
Texture Technology
Vietnamese factories use advanced surface treatments to achieve realistic wood grain:

Technique    Description
3D Wood Grain Embossing    High-resolution pressing creates tactile grain texture matching visual pattern 
Brushed Finish    Wire-brushing removes soft material to create open-grain feel 
Co-extrusion    Capped layer provides additional UV protection and color consistency 
6. Cost Advantages of Vietnam Sourcing
Sourcing WPC flooring from Vietnam offers significant economic benefits compared to other origins.

Pricing Comparison Factors
Factor    Vietnam Advantage
Labor Costs    Lower than China, Taiwan, Korea
Raw Material Access    Abundant local wood fiber from rubberwood and acacia plantations
Trade Agreements    EVFTA (EU-Vietnam Free Trade Agreement) reduces or eliminates tariffs for European buyers 
Shipping Costs    Direct container shipping to Europe (Hai Phong to Rotterdam: ~30-35 days) and North America (to Los Angeles: ~20-25 days)
MOQ Flexibility    Lower minimums available (1x20ft container vs. full truckloads from larger producers) 
Typical Pricing Indicators (Industry Estimates)
Product Type    Estimated FOB Price (Hai Phong/Cat Lai)
Hollow WPC Decking (140x25mm)    $8-14 USD / sqm
Solid WPC Decking (145x21mm)    $12-20 USD / sqm
