Centric’s revolutionary patented structural board can be made from either bamboo, or the perennial grass, Arundo Donax. Both raw materials are eco-friendly, and share identical structural properties when manufactured to Centric’s specifications. Since bamboo and Arundo Donax are non-wood based material, we are contributing to mitigating deforestation of the world’s forests.
Certified Test Result Comparison of Centric’s Infinity Board™ to conventional plywood and OSB.
Centric’s Infinity Board™ is:
Several mechanical and physical tests were conducted by TECO of Eugene, Oregon, to obtain key physical characteristics of Centric’s Infinity Board™ (measured in 5/16” thickness). ASTM D1037 specification, titled “Standard Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel Materials” were used extensively for these tests.
A separate report was provided by TECO which provided test details, results and
photographs showing test coupons and set up.
The Table shown below summarizes the laboratory test results and how they compare to the currently used structural wood-based materials such as plywood and OSB.

** The 34,000 and 185 values for plywood were obtained from Table 4B of “Panel Design
Specification” published by APA The Engineered Wood Association, for a 11/32thick plywood. The
results indicate that Centric 3D-OSP laminated material is capable of meeting the panel bending/strength stiffness requirements set forth by APA.
