Working with Bamboo Plywood LAM-NAT
Is Bamboo Plywood easy to machine?
Cuts, routs and CNC-machines like dense hardwood — use carbide or PCD tooling and climb-cut/scoring to avoid glue-line chipping; silica and cured resin accelerate edge wear.
Can Bamboo Plywood be welded?
Not weldable; joined by PVA/PU/epoxy adhesives, dowels, dominos or mechanical fasteners with pre-drilled pilot holes.
Can Bamboo Plywood be formed, bent or molded?
Flat panels are not post-formable; curved parts are made by cold-bending thin plies or hot-pressing bamboo veneers over a mould during lay-up.
What surface finishes work on Bamboo Plywood?
Sands to a fine surface; finish with oil, hardwax, water-based PU or UV lacquer — seal all edges and end grain to limit moisture uptake and swelling.
Bamboo Plywood chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
