Bamboo flooring Brief introduction

The bamboo flooring planks are machined with tongue and groove edges to provide interlocking assembly. The ends are also end-matched with tongue and groove. Each piece is machine sanded on top, with rough glue-ready surface on bottom. The edge above the tongue on the long edge is angled and ready to accept standard flooring nails. 　Each pre-finished bamboo flooring is coated with a clear, UV cured acrylic polyurethane. State of the art machinery is used to apply and cure the durable coating. 　Three layer, all bamboo, tongue and groove plank 24 or 36 inches long by 3 5/8 inches wide by 5/8 inch thick, factory pre-finished with 3 coats of 100% solids UV cured Acrylic Urethane. ABRASION RESISTANCE 　Bamboo flooring tested according to ASTM C501 (H-22 Calibrated wheels loaded with 1000 gram weight at 70 RPM for 1000 cycles) weight loss = .349 grams =..012 ounces. The test we have done for abrasion resistance showed that Bam Plank tm finish is one of the toughest to be found in the wood flooring industry. FLAMMABILITY 　Bamboo flooring tested according to ASTM E648 Critical RadiantPanel Test. Passes with a CLASS I rating per NFPA "Life Safety Code". (Can be used in all classes of buildings.) SMOKE DENSITY 　Bamboo flooring tested according to ASTM E622 pass = 450 or less , passes with 269flaming mode and 329 non-flaming mode. CHEMICAL AND STAIN RESISTANCE 　Bamboo flooring tested with the following chemical reagents finish was unaffected:Acetic Acid (5%) Acetone Ammonium Hydroxide (10%) Toluene 　Detergent Solution Ethyl Alcohol (50%) Hydrochloric Acid(10%) Turpentine Heavy Duty (.025%) Hydrogen Peroxide (3%) Soap Solution (1%) SodiumHydroxide (1%) INDENTATION RESISTANCE 　Bamboo flooring according to ASTM 1037 (Janka Ball Hardness) showed anaverage hardness of 1640. (27% harder than northern red oak and 14% harder than hard maple) DIMENSIONAL STABILITY 　Bamboo flooring according to standard method for wood flooring showed adimensional change coefficient of .00144 . (50% more stable than red oak) SLIP RESISTANCE 　Bamboo flooring according to ASTM D2047 = results 0.71 coefficient of　Friction. Static efficient of 590 exceeds the OSHA recommendation for level surfaces in the workplace. COMPRESSIVE STRENGTH 　Bamboo flooring according to ASTM D3501-86 A = results A) Parallel to Grain= 7,549 PSI B) Perpendicular to Grain =2,566 PSI C) Flat wise = 16,925PSI at 50% Strain. (Load to compress to 1/2 thickness) BENDING STRENGTH 　Bamboo flooring tested according to ASTM D3043-87 result = 13,608 PSIBENDING ELASTICITY MODULUS943,443 PSI SHEAR STRENGTH 　Bamboo flooring tested according to BRITISH STANDARD # 373 result = Parallel to Grain 1365 PSI TENSILE STRENGTH 　Bamboo flooring tested according to ASTM D3500-90 A result = Parallel to Grain15,290 PSI 　These test results can also find some other bamboo flooring company, but their product not the same material, so the result maybe not quite same. If you are interested, we can offer some pieces of bamboo flooring samples for your test.
