–  5,000-plus pound rating higher than most durable hardwood floors; extremely resistant to dents, scratches, nailing –

SAN DIEGO – September 13, 2010 Cali Bamboo, , a premier manufacturer of green building materials for residential and commercial projects made primarily from bamboo, received a 5,000-plus pound Janka hardness rating for its Fossilized® HD Bamboo Flooring line.
The findings are significantly higher than what is normally seen by every other traditional floor product, making the bamboo offerings one of the most resistant products to dents.
Tests performed by third party laboratories typically find Janka hardness ratings for most strand woven bamboo floors test closer to 3,000 pounds. Recent Janka hardness testing performed by an Oregon based accredited laboratory, Professional Service Industries, Inc, (PSI) revealed a Cali Bamboo Fossilized® HD bamboo floor rating that exceeds 5,000 pounds.  Public Janka hardness findings on some the most expensive and exotic tropical hardwood only comes up at 4,500 pounds.
The Janka test analyzes the hardness of wood by measuring the force required to embed an 11.28 millimeter (0.444 inch) steel ball into wood to half of the ball’s diameter. PSI used two samples each of Cali Bamboo® Natural and Java Fossilized® HD Wide Plank Bamboo Flooring in accordance with ASTM International’s standards, the recognized authority for such studies.“The tests came up so high that I asked PSI to recalibrate the machines and repeat the test for a second time to ensure this was in fact accurate,” said Jeff Goldberg, CEO of Cali Bamboo. “They were, and we’re extremely proud of the results!” Learn More.Cali Bamboo’s Fossilized® HD Wide Plank Bamboo Flooring lines are forged in an incredibly unique process of compressing and intertwining the fibers. In doing so, a dense, “fossilized” bamboo block is formed that is then milled using precision laser guided machines before the final scratch-resistant curing phase. This flooring can be used in radiant heat systems, commercial applications, high  traffic areas, or anywhere a beautiful, indestructible floor is desired.
