  • Designed to be especially cost effective and functional in application.
  • Aesthetically attractive profile with reinforcing web on the corrugations spaced by wide pans, making it uniquely distinct from other roofing.
  • Steel sheets are strengthened because of corrugations. With the additional reinforcing web, the strength of the KAWA R805 profile is further enhanced.

Roof Pitch

The minimum recommended roof pitch for the KAWA R805 profile is 3˚. For sheet lengths greater than 31 metres, the pitch should be increased by 1˚ for every 5 metres of additional length.

End Laps

Should end laps be inevitable, have a minimum of 250 mm end lap for a 5 ˚ roof pitch and below, and a minimum 200 mm end lap for a roof pitch exceeding 5˚. Ensure watertightness by applying a good sealant to the end lap.

Stop Ending & Lipping

Stop ending sheets prevent water from entering the building through the flashingor capping. It is done by a turn-up tool, turning up the tray between crests atthe ridge end of the sheet (Fig.1). Lipping is a process whereby a turn-downtool is used to turn down the tray between crests at the eave end of the sheet(Fig.2). Lipping prevents water from being driven into the building by wind orcapillary action. Both of these operations can be carried out before or after theinstallation of the sheets. In the case of the latter, ensure that sufficient clearanceis available for the movement of the turn-up/turn-down tool. It is recommendedto lip pans of all sheets that have a slope less than 5 ̊.
