The KAWA KZ Standing Seam Series is a concealed roof fixing system. It can be uniquely rollformed by a proprietary process to precisely taper to exact angles and dimensions in a single pass. Each sidelap is locked and seamed by a robotic seamer against strong winds and heavy rains. The wide tray design disperses water efficiently from the roof surface, even at a minimum roof pitch of 1 degree. Widths of 300 mm, 400 mm, 500 mm and 600 mm are available.

  • A non-puncturing boltless roof system.
  • Unique lock and seam fastening ensures a 100% watertight roof.
  • Light in weight but yet strong.
  • Quick and efficient installation.
  • Allows the construction of engineered built-up system for maximum heat and sound insulation.
  • Excellent corrosion resistance  - made only with premium coated steel from BlueScope. Also available in aluminium, copper and stainless steel substrate.
  • Engineered to precisely taper in a single pass. Speeds up work and eliminates frequently encountered errors in the normally used antiquated multiple pass process.

Roof Pitch

The KAWA KZ Standing Seam Series profile can be installed on a roof pitch as low as 1˚, making it virtually flat. However, it is recommended that a roof pitch of 2˚ be considered during designing to avoid silt accumulation due to reduced water velocity and possible ponding as a result of uneven purlins.

End Laps

Where end laps are 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 water tightness by applying a good sealant to the end lap.

Stop Ending & Lipping

Stop ending sheets prevent water from entering the building through the flashing or capping. It is done by a turn-up tool, turning up the tray between crests at the ridge end of the sheet (Fig.1). Lipping is a process whereby a turn-down tool is used to turn down the tray between crests at the eave end of the sheet (Fig.2).
