Rheinzink, Burnaby, B.C., Canada, offers Rheinzink-massiv roof-drainage systems with a wide range of shapes and individual application options. They include rainwater pipes, half-round and box gutters, numerous special shapes in standard dimensions and the associated accessories. Whether bright-rolled or “pre-weathered,” all prefabricated parts are made of the same high-quality material. The formation of a natural patina ensures that the roof drainage systems will fulfill their function for many years without any need for maintenance. Also available are Rheinzink-Rauten, interlocking, pre-weathered tiles. The tiles have a square or pointed (parallelogram) shape and are provided with simple cleats on all four sides. When roofing or cladding, the tiles are laid so that the diagonals lie in the direction of the fall.
