  • A stronger roof that contributes by reinforcing the entire steel structure.
  • Less purlins used due to its high structural integrity, consequently lowering the total building cost.
  • With it's deep corrugations, only a low roof pitch is needed as the possibility of water overflowing into the side laps becomes non-existent.
  • Fascia cost is drastically reduced since only a small fascia is required for a flatter roof.
  • A profile bold in design, making it uniquely more expressive.

Valley Fastening of KAWA R600 as a Wall Cladding

Roof Pitch

The KAWA R600 profile can be installed on a roof pitch as low as 1º, making it virtually flat. However, it is recommended that a roof pitch of 2 º 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 º roof pitch and below, and a minimum 200 mm end lap for a roof pitch exceeding 5 º. Ensure watertightness by applying a good sealant to the end lap.

Stop Ending & Lipping

The high ribs and trapezoidal shape of the KAWA R600 profile requires usage of end stops on the ridge side to prevent rainwater being driven into the building. The end stops are prelined with sealants before being fastened to the sheets by a snapping tool.

Crimped Curved Roof

The KAWA R600 Crimped Curved profile adds beauty and functionality to the building envelope with advantages as follows:-

  • Fewer structural supports required for fascias and roofs.
  • Aesthetically attractive exterior finish with simple installation.
  • Reduced number of flashings and cappings.

Ensure that the sheets are lifted onto the roof the right way up with the male and female ribs in the desired direction, otherwise sheets will have to be orientated during installation.

Where a few sheets are required to cover the whole length of the roof due to handling or transport considerations, installation shall start from the bottom to the top before moving on to the next run of roof. At the end laps, a minimum of 250 mm end lap is required for a 5 ˚ roof pitch and below, and a minimum of 200 mm end lap is required for a roof pitch exceeding 5 ˚ . To ensure watertightness, apply a good sealant to the end lap.

For the KAWA R600 Crimped Curved profile, valley fixing of the sheet is recommended only on the fascia purlin. For the rest of the purlins, screws should be fixed on the crests of the ribs which are supported by roof connectors.
