Nurajack Calculation Sheet - Step 2

Input

Area

• Min distance from deck surface to bottom of joist mm
• Width of deck (dimension with fall) mm
• Fall Ratio (Slope Angle) 1:100 (0.6°) 1:80  (0.7°) 1:60  (1.0°) 1:50  (1.3°) 1:40  (1.5°) 1:30  (2.0°) 1:20  (3.0°) 1:10  (6.0°)
• Calculated number of Joists Across (from Step 1)
• Calculated number of Nurajacks (from Step 1)

Result
