    Recommended Laying And Jointing Procedures For Best Results

    01. The Laying of sheets should be such that the required end lap of min. 150 mm. and an overhang at eaves of 300 mm is attained with standard purlin spacing.

    02. The sheets must be laid from left to right commencing at the eaves as shown if fig.1. Keeping the downward corrugation always to the left so that the subsequent sheets are placed correctly. The First sheet should be so placed giving specified overhang at eaves.

    03. The sheet 'B' is placed next with the corner 'mitred' on the lower right side as shown in fig. 1.

    04. Ridge sheet 'C' and all other sheets of the same slope have to be fixed in a straight line.

    05. The next line of sheets is started with sheet D(fig. 1) which is 'Mitred' at the left top corner to provide a snug fitting. Mitre sheets with ordinary hand saw. Do not chip. (See fig. 2)

    06. All sheets must have the correct side lap of half a corrugation (fig. 3) ensuring that the eaves line is straight.

    07. Sheet 'E' is placed next with it's top left & lower right corners mitred.

    08. Sheet 'F' is placed next with mitring at the lower right corner.

    09. Sheet 'G' and 'H' are placed with top left corners mitred.

    10. Sheet 'I' is placed without any mitring.

    11. As shown if Fig.3, the distance between bolts must be 279.4mm. keep an endlap of minimum 150 mm (See fig.4) and an overhang at eaves of 300 mm. with standard purlin spacing.

    12. The sheets are bolted with the help of 'J' bolts or 'L' as the case may be with GI & bitumen washers.

    13.Hookbolts must be tightened adequately to ensure that the space between the hole & bolt is covered by the bitumen washer. Overtightening should be avoided.

    14. Intermediate purlings also should have bolts fixed.

    15. Holes for insertion of bolts must only be drilled and never punched.

    16. Mitring of sheets should be done with an ordinary hack saw and never be chipped.

    17. Ensure all sheet are laid with their smooth side upwards.

    18. As per IS 3007 (Code of practice for laying A.C. Sheets) workmen are advised to use aluminium cat ladders, especially while working during the monsoons.

    Note :

    • Use Catladders or safety belts.
    • Walk along the line of the purlin only.
    • Wet the sheet before drilling and mitring.
