Precast V-Drains
V Drains are cast to suit site requirements.
We have a standard V-Drain of 1200mm wide x 1000mm long.
Any other V-Drain will be quoted on request and the length will be determined by the size required and the calculated weight.
Equal Leg U Channels
Channels can be cast to be used as open channels or cast with Angle Iron inserts to accommodate grids.
Depending on the application we manufacture a Medium Duty U-Channel or a Heavy & Extra Heavy Duty Channel to accommodate traffic areas.
Channels can be covered with solid slabs or grids.
We offer polymer grids directly from our factory, or alternatively, Rectagrid or Mentis Grid can be used.
These grids are not supplied with the channel but Twinstar will supply the dimensions for easy ordering from your supplier.
Extra Heavy Duty Channels
Extra Heavy Duty Channels designed for high volume traffic areas or heavy-duty vehicles.
Grid Inlets
Junction Slabs
Stormwater Manhole Slabs
