Japanese Cedar (Sugi) 5/4 Inch Decking
Japanese Cedar (Sugi) 5/4-inch boards bring extra thickness where it counts — the added stiffness handles spans, seating loads, and outdoor exposure that thinner boards can't.
Best for
- Sauna benches and backrests (naturally low resin, stays comfortable against skin)
- Outdoor and garden benches built to last BC's wet seasons
- Shelving, seat tops, and countertop-style surfaces
- Exterior trim and fascia with real visual presence
Sugi's tight, fine grain and natural oils give it exceptional durability — resistant to rot, insects, and moisture without any treatment needed. Available in 5" and 6" widths, 8, 10 & 12 feet.
