SOLUTION   A. Corrugated G.I. Sheets   Determine the number of roof sheet. Refer to Table 6-2, Using 2 ½ corrugations; Divide: 18.00 m = 30 pcs. .60   The length of the rafter is 6.00 meters or a combination of 3.60 and 2.70 meters. (12’ and 9’) roof sheet (see Table 6-5) multiply each sheet length by the result of step -1.   30 pcs. 32” x 12 ft. and 30 pcs. 32” x 9 ft. G.I. roof sheets.   Take note that this is only one side of the roof. For two sides, double the quantity. 2 x 30 = 60 pcs x 32 x 12 ft

B. Umbrella Nails   Determine the number of umbrella nails for the 12 ft. and 9 ft. roof sheets. Refer to Table 6-2; Multiply : 60 pcs. of 1 ft. x 26 = 1,560 pieces 60 pcs. of 9 ft. x 22 = 1,320 pieces Total……...2,880 pieces   Convert to kilograms. Refer to Table 6-3; Divide: 2,880 = 24 kilograms of umbrella nail  120

A. Corrugated G.I. Sheet   1.Determine the number of roof sheet. Refer to Table 6-2;  Divide : 12.90 m. = 21.5 say 22 pcs.   .60      2.Determine the length of the rafter = 4.80 m. or 16ft. Refer to Table 6-5. For 16 ft. it requires a combination of 10 ft.  and 7 ft. or 9 ft. and 8 ft. Thus, Order:  22 pcs. of 32” x 10 ft. and 22 pcs. of 32” x 7 ft. roofing sheets   3.Again, take note that this is only for one side of the roof. To include the other side, double the quantity.  2 x 22 = 44 pcs. of 32” x 9’ and 2 x 22 = 44 pcs of 32” x 8’ roof sheets.   B. Roof Nails and Lead Washers   4.Solve for the quantity of roof nails. Refer to Table 6-2;  For 3.00 m. (10 ft.) sheet: 44 x 22 = 968 pcs. For 2.10 m.  (7 ft.)  sheet: 44 x 18 = 792 pcs.       Total roof nails…………………   1,760 pcs   2.Convert 1,760 pcs. into kilograms. Refer to Table 6-3;  Divide: 1,760 = 14.7 say 15 kilos G.I. roof nails  120   1760 = 23.5 say 24 kilos lead washers.   75

SOLUTION   A. Roofing Sheets   Determine the number of roofing sheet in one row along the 18.00 m. length of the gutter. Refer to Table 6-2 for 2 - ½ side lap corrugation. Divide: 18.00 m. = 30 pcs.       .60       Determine the length of the rafter. For a 6.00 meters long, choose a combination of 12 ft. and ft. roof sheet. See Table 6-5,   30 pcs. of 32” x 12 ft. and 30 pcs. of 32” x   9 ft. corrugated G.I. sheet   Take note that the above quantity is only for one side of the roof. To include the other side double the quantity. 2 x 30 = 60 pcs. 12 ft. and 2 x 30 = 60 pcs.   9 ft. roofing sheets Considering that the roof is a hipped type, wastage on cutting can not be avoided, hence add 5% allowance if the angle of the hip is 45° and 10° if not 45°. The percentage allowance shall be multiplied to the total number of sheets. Get a longer sheet to avoid excessive waste in cutting. Thus,   60 + 60 = 120 pcs. x 5% = 6 pcs. of 12 ft.   Order :   66 pcs. 32” x 12 ft. and 60 pcs. 32” x 9 ft. corrugated G.I. sheets    

B. G.I. Rivets   Determine the number of rivets. Refer to Table 6-2; Multiply: For 12 ft. sheet: 60 x 26 = 1,560 pcs. For   9 ft. sheet: 60 x 22 = 1,320 pcs. Total number of rivets……2,880 pcs.   Convert to kilograms: Refer to Table 6-3; Divide: 2,880 = 16 kilograms        180 C. G.I. and Lead Washers       Double the number of rivets = 2880 x 2 = 5,760 pcs. Refer to Table 6-3, Divide: 5760 = 45.7 say 46 kilograms 126   Lead washer is the same number as the rivets. Refer to Table 6-3 Divide: 2,880 pcs. = 38.4 say 39 kilograms    75   D. Plain G.I. Anchor Strap   Refer to Table 6-4. The Size of G.I. strap on a 2” x 4” purlins is 1"  x  10" .   Number of strap is equal to the number of rivets = 2,880. Solve for the number of plain sheet. Refer to Table 6-4. Divide:

Gutter, Flashing, Ridge, Hipped and Valley Roll TINSMITHING WORK

THE PRIMARY CONSIDERATION IN TINSMITHING WORK IS ECONOMY WHICH SIMPLY MEAN: “TO UTILIZE EVERY INCH OF THE TIN SHEET”. Estimating Procedures :  1.Determine the total length of the gutter in meter. 2.Divide this length by 2.35 meter to find the number of gutter required. (2.35 m. is the effective length of one gutter.) 3.Find the total width of one gutter. ( see the detailed plan.) 4.Divide .90 meter (36 inches width of one plain G.I. sheets by the result of step-3 to find out how many gutter could be made out from one plain G.I. sheet. The fractional value or extra cut will be reserved for other smaller parts. 5.Divide the result of step-2 by the result of step-4. the result is the required number of G.I. sheets.

SOLUTION   Find the total length of the gutter.   Length = 2 (18.00 ) + 2 ( 10.00 )                          = 36.00 + 20.00                   L     = 56.00 meters.   Divide the length by 2.35 meters the effective length of one gutter.   56.00   =   23.82 say 24 pcs.  2.35   The total width of the gutter is 52.5 centimeters (see cross section of gutter). Subtract 52.5 from 90 centimeters the standard width of one plain G.I sheet.

This 37.5 centimeters excess cut from one plain G.I. sheet could be set aside momentarily to be considered in making other roof accessories such as flashing, downspout, anchor strap for riveting etc. Thus, only one gutter at 2.40 m (8 ft.) long could be made out from one plain G.I sheet.   Therefore, order :   24 pcs. 90 cm. x 240 cm.(36” x 8 ft.) Plain G.I. sheet.
