The truss

A traditional form of roof construction is that of using trusses. The beams placed in this way allow you to cover a greater light (distance) to the roof without using intermediate support points.

Even long truss structures are installed today, in these cases lamellar wood is used.

The parts that make up a truss have specific names, each one covering a specific function.

Chain, stretched section, sometimes can be made with metal pulls
Monaco, vertical element on which the roof ridge rests
Lightning, stiffen the truss structure
Strut, inclined beam on which purlins are fixed.
Arcarecci, joists joining the trusses
Panel or Beads, creates the base of support for the cover package above.
