Metsec Lattice roof Beam solutions can be designed to incorporate cantilever or 'oversail' eaves details.
The cantilever can be pre-engineered from either lightweight cold-rolled steel section or from hot-rolled joist section depending on loadings and cantilever length.
This detail can be used for small span cantilevers of up to 1m. Stiffener
angles can be welded to the sides of the top chord of the steel beam, if required, to provide an economic
cantilever solution.
This detail can be used for medium span cantilevers of up to 2m. The
cantilever arm is bolted to the end post which is supplied welded into the end of
the lattice steel truss. Since the cantilever roof element does not require an insulation layer
the line of the supporting cantilever eaves structure is correspondingly raised
to support the top sheet.
This detail can be used for large span cantilevers of over 2m. The cantilever
arm extends into the building to provide an adequate backing span and is bolted
on to the top chord of the lattice steel truss.
