Structural Properties

D-Blaze® FRT wood has been tested by independent laboratories following industry standards ASTM D 5516 & ASTM D 5664 to develop strength reduction factors for various use conditions, including roof temperatures of up to 150° F for lumber and 170° F for plywood. Consult Table 1 (D-Blaze® Lumber Strength Design Adjustment Factors) and Table 2, 3 and 4 (D-Blaze® Plywood Span Rating Adjustments) for specific adjustment factors.
