MATERIALS IN ROOF

Length of Purlins of the roof=24 m

A. Corrugated Sheet (using 2 corrugations)

1) 22.5/0.6=37.5 40 sheets in one row.

2) Since length of rafter is 5.4m

3) Order 38(2)(2)=160 pcs 32x10

B. Rivets

1) For 10 long

160x22=3520 pcs

2) Convert to kilograms

3520/180=19.56Kg or 20 Kg

C. Washers

1) Double the no. of rivets

3520(2)=7040 pcs

2) Convert to kilograms

7040/126=55.
