Engineered Bamboo flooring (Horizontal / Vertical)
Species:Mao Zhu (Moso) (Phyllostachys Pubescens)
Structure:Top Wear Bamboo + Fir layer Core + Poplar layer
Finish:All should be A Grade flooring and is finished with 8 coats ( 6 coats of primer and 2 coasts of surface ) of Treffert brand semi-gloss finish for the regular bamboo, scratch resistant, UV cured aluminum oxide urethane.
Height Difference:Connected panels are to have NO visible height difference at any connected corner or along the seam (tolerance = 0.10mm)
Mouse Bites:Milling tools must be sharp enough to eliminate the appearance of white lines or micro-chips along the long and short edges of the panels. Bare fingers tips running up and down the joint of connected panels will not feel shards caused by rough cutting
Function:Locking system must connect on both long and short seams without difficulty and maintain a secure connection
