Your Roof Is Failing Because Of This! The Shocking Truth About Tuff Rib Dimensions!

36 panel coverage, 3/4 rib height panel length: 1250 x 2. 4 = 3000 screws 3000 250 = 12 bags example: Your order is for a roof of 4162 square feet with rows of screws spaced 2' on center. 4162 100 = 41. 62 square. 41. 62 x 70 = 2913 screws 2913 250 = 11. 66 or 12 bags

Much more affordable than standing seam roofs, which are the type of metal roof with concealed fasteners and a more premium look, the material can provide better longevity than. Shear load and stiffness chart shear load test results for tuff rib panels at support spacing of 4 0. Pu = maximum applied load in the cantilever beam test (lb) = 0. 4pu in the cantilever beam test (lb) n = net shear deflection of diaphragm (in) at 0. 4pu load g = shear stiffness of the diaphragm as determined from test.
