Roof trusses

Fink truss

A fink truss is the standard pitched roof truss, with internal webs arranged in a W; it is the most widely used truss type for houses.

Also known as fink truss, W truss, standard truss, common truss, W-type truss

The W web pattern gives a very good ratio of strength to timber, which is why the fink truss is the default for duo-pitched roofs on homes. It is typically used for spans of roughly 5 to 10 metres; a double fink (double W) adds more webs for longer spans.

It goes by several names: W truss in Scandinavia, fink in the UK and North America, and simply standard or common truss in many product ranges.

Web (truss web)Webs are the internal members of a truss that connect the top and bottom chords and divide the truss into triangles. Fan trussA fan truss has webs that fan out from points on the bottom chord to the top chord, giving the top chord extra support.
