BG-Gatic CastSlot

CastSlot is first choice where constant, slow turning traffic is a major consideration. Originally designed for supermarket car parks, delivery and distribution areas, CastSlot has become a trusted staple in surface water drainage specifications for projects where load ratings can reach F900.

The subtle profile of CastSlot sits neatly within concrete, asphalt, and block surface finishes. CastSlot features an electro painted ductile iron throat section, which is securely fixed to the galvanised steel channel body to provide an exceptionally robust yet discreet drainage system.

CastSlot is available with a 30mm opening and a Treadsafe option, which reduces the slot opening from 30mm wide to 2 x 10mm wide slots.

Load Classification: A15 to F900

Available channel widths:

High capacity surface water drainage
100mm, 150mm, 225mm, 300mm, 350mm, 400mm, 500mm, 600mm
