Annex 4 Installation of steel roof of trapezoidal plates in the sizes 10 – 31
4.1
Overview
• Mount rails A1, B2, C3, D4, E5 on the unit for support of trapezoidal roof plates (mount also rails Y and Z on units of
the size 30 and on units that are larger than size 30 longitudinally at the centre- line of the units).
• Place foam bands – P – on the horizontal rails A1, B2, C3 and D4 for support of roof plates.
• Calculate overhang of the roof at both ends of the unit and mount roof overhang profile – G1 on the first trapezoidal
roof plate – F1 before the roof plate is mounted.
• Place and mount roof plates F1, F2, F3 and so on.
• Remember foam bands on the side laps between roof plates to prevent rainwater from passing through.
• Place roof overhang profile – G5 at the other end of the unit before the last roof plate is mounted.
• Mount sides and corners on the roof.
• Apply sealing where plates are joined to ensure water resistance - even in stormy weather.
4.1.1
Mount rails. Units of size 10, 11, 12, and 14
Squeeze sealant in sufficient quantity between the underside of the rails A1, B2, C3, D4, E5 and the horizontal top side
of the unit before the rails are mounted. This means that the rails are standing on sealant to achieve the tightest
