Type 670 BLÜCHER® Channel without outlet box for concrete, tiled or epoxy floors.
Measurements are in Millimetres
BLÜCHER® Channel are thin-walled drain channels, TIG-welded and acid-pickled. Channels for concrete or concrete tiled floors have a wall thickness of 2 mm. Channels with a length in excess of 2000 mm are fitted with cross bars which stabilize the channel and safeguard it against being deformed during casting. Furthermore, cross bars prevent the gratings from dislocating along the length of the channel. In slot channels, the longitudinal fall is 0.6%, in other channels 1%. The cross fall corresponds to 130° for slot channels and 150°-170° for other types of channels.
