Composite Wood / Wood Plastic Composite (WPC) — Non-botanical (Polyethylene / Wood Fiber Blend)
High; the recurring uniform texture, lack of pore structure, and 'frosted' surface finish are definitive markers of a composite decking product. confidence

Composite Wood / Wood Plastic Composite (WPC)

Non-botanical (Polyethylene / Wood Fiber Blend) · Engineered

Type
Engineered
Origin
Manufactured globally; components typically sourced from domestic wood waste and recycled plastics.
Hardness
Varies by density; typically 1,200 - 1,800 lbf (Hard classification equivalent).
Durability
Very Durable; engineered for extreme rot, insect, and moisture resistance; does not decay like natural wood.

Grain Pattern

Uniform linear texture with simulated embossed grain; lacks organic growth rings or cellular tracheid structures.

Color & Appearance

Beige to tan with a weathered grey/frosted surface patina; consistent color through the material with high UV resistance and low luster.

Hardness (Janka)

Varies by density; typically 1,200 - 1,800 lbf (Hard classification equivalent).

Durability & Decay Resistance

Very Durable; engineered for extreme rot, insect, and moisture resistance; does not decay like natural wood.

Value & Sustainability

Estimated Market Value
$3.00 - $6.00 per linear foot (standard decking profile).
Wood Age Estimate
Contemporary manufacture (less than 5-10 years), showing minimal environmental oxidation or wear.
Sustainability Status
Highly sustainable; often made from up to 95% recycled content (sawdust and plastic bags); FSC not applicable.

Common Uses

Outdoor decking, fencing, railing systems, and exterior trim board.

Geographic Origin

Manufactured globally; components typically sourced from domestic wood waste and recycled plastics.

Workability

Cuts and drills similarly to softwood but can melt if blades are dull; requires no sanding or staining; holds screws well but has high thermal expansion.

Finish Recommendations

None required; staining or painting is generally not recommended as the material is designed to be maintenance-free.

Notable Features

Slight plastic scent when cut; splinter-free; waterproof; lacks natural wood grain variance; often heavier than natural timber.
