The KAWA R650 Lockseam signals a new era in conventional roof fixing technology. The constant fear of wind uplift and rainwater entering the side laps of roof sheets is now totally eliminated. With the KAWA R650 Lockseam, each side lap is locked and seamed by a revolutionary robotic seamer against high winds and rainstorms.

The KAWA R650 Lockseam signals a new era in conventional roof fixing technology. The constant fear of wind uplift and rainwater entering the side laps of roof sheets is now totally eliminated. With the KAWA R650 Lockseam, each side lap is locked and seamed by a revolutionary robotic seamer against high winds and rainstorms.

Roof Pitch

Owing to its unique deep corrugations, the KAWA R650 Lockseam 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

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.

End Stops

The high ribs and trapezoidal shape of the KAWA R650 Lockseam profile requires usage of end stops on the ridge side to prevent rainwater being driven into the building. The end stops are pre-lined with sealants before being fastened to the sheets by a snapping tool.

  • A non-puncturing boltless roof, thus reducing potential leaks at fasteners.
  • A concealed fixing system, resulting in a roof with clean lines uninterrupted by protruding screws or bolts and ensuring 100% watertightness.
  • The unique lock and seam fastening process by a robotic seamer holds the roof sheets tightly against uplift or suction forces of strong winds.
  • The profile’s strikingly bold and deep corrugations make it an extremely structurally strong roof requiring fewer purlins, an almost flat roof pitch with a small fascia, all of which contribute to substantial savings in building costs.
