Lauan (also known as Meranti or Philippine Mahogany)
Shorea spp. • Exotic/Tropical
Grain Pattern
Uniform straight grain with a medium to coarse texture; features long, linear vessels and a consistent, somewhat stringy appearance typical of rotary-cut or flat-sawn veneer surfaces.
Color Description
Light to medium reddish-brown or tan heartwood with subtle golden undertones. Sapwood is typically lighter gray-yellow. It has a low to moderate luster and tends to darken slightly to a duller brown over time with light exposure.
Hardness Rating
800 lbf (Soft)
Durability Rating
Slightly Durable to Non-durable; poor resistance to decay and highly susceptible to insect attack, specifically powderpost beetles as evidenced by small exit holes in the sample.
Common Uses
Plywood cores, underlayment, hollow-core doors, inexpensive furniture, crates, and interior millwork; often used as a utilitarian 'mahogany' substitute.
Geographic Origin
Southeast Asia (primarily Philippines, Malaysia, and Indonesia)
Market Value & Sustainability
Estimated Market Value
$3.00 - $5.00 per board foot for solid lumber; significantly less for utility-grade plywood sheets.
Wood Age Estimate
Estimated 20–40 years old based on the presence of oxidation, surface wear, and established insect exit holes suggesting it has been part of a structure or utility board for some time.
Sustainability Status
Many Shorea species are listed as 'Critically Endangered' on the IUCN Red List due to over-harvesting; FSC certification is available but not standard for all Lauan products.
Workability
Generally easy to work with both hand and machine tools, though its stringy nature can cause fuzzy surfaces during sanding. Glues and finishes well.
Notable Features
Presence of active or historical insect bore holes (pinholes). Very lightweight for its appearance and often lacks the distinct spicy scent associated with true mahogany.
Finish Recommendations
Requires a grain filler for a smooth high-gloss finish; otherwise, standard polyurethane or lacquer works well. It absorbs stains easily but can appear blotchy without a sealer.
Identification Confidence
Medium-High; the open-pore structure, color, and specific pattern of insect damage are classic indicators of Lauan/Meranti plywood often found in older construction.
