Grain Pattern
Artificial embossed wood-grain texture designed to mimic flat-sawn timber with deep synthetic ticking and grooves.
Color & Appearance
Uniform tan or cedar-tone pigment with intentionally dark streaking; color is consistent throughout the material and highly UV-resistant to prevent graying.
Hardness (Janka)
N/A (Typically 1,000-2,000 lbf in equivalent Janka testing, classified as Hard)
Durability & Decay Resistance
Very Durable; engineered to be completely resistant to rot, fungal decay, and wood-boring insects. Highly weather-resistant.
Value & Sustainability
- Estimated Market Value
- $3.00 - $6.00 per linear foot (depending on brand and profile thickness).
- Wood Age Estimate
- Sample appears to be modern production (0-5 years old) showing no significant weathering or oxidation.
- Sustainability Status
- Highly sustainable; typically made from recycled wood fibers/sawdust and recycled plastics (polyethylene or PVC). FSC does not apply.
Common Uses
Outdoor decking, wall cladding, fencing, and exterior railing systems.
Geographic Origin
Manufactured globally; common brands include Trex, Azek, or Fiberon.
Workability
Easily worked with standard woodworking tools; however, it is denser than natural wood and can melt if blades are dull. Does not require sanding or staining.
Finish Recommendations
No finish recommended or required. Painting or staining often voids manufacturer warranties and does not adhere well.
Notable Features
Scent of plastic when cut; high thermal expansion/contraction; waterproof; heavy weight; maintenance-free.
