Minimum roof slope for corrugated GI sheet roofing (IS standards):
Steel StructuresRoof Trusses SteelMEDIUM
Choose the correct answer
A
1:12 (5°)
B
1:3 (18°)
C
1:6 (9°)
D
1:20 (3°)
Correct Answer
C. 1:6 (9°)
Why is this the answer?
GI corrugated sheet: minimum slope 1:6 (≈9°). Asbestos cement sheet: 1:5 (≈11°). Lower slopes risk water ponding and leakage at laps. End laps should increase with decreasing slope.
