Wincro Channels provide positive anchorages for fixing components and allow generous tolerances for setting-out.

Channel applications include:

  • Channels with ‘T’ head bolts, which provide fixing locations for Wincro masonry support systems and the Wincro range of windposts.
  • Retention of the standard range of either brickwork or cladding ties or special purpose-made components (see manufacturer's Ties and Restraints product catalogue).
  • Use as a framing medium to retain flat or curved cladding, or for carrying services supports.

Wincro Channels have a rectangular cross-section with nail holes for securing to shuttering. They are filled with expanded polystyrene to prevent the ingress of concrete during casting.

Fixing to channels is by 'T' head bolts. Tapped plate washers can be used as an alternative to 'T' bolts where non-standard bolt lengths or diameters are required.

Wall ties can also be used with WC23 (23/19), WC28 (28/15) and WC38 (38/17) cast in channels.
