Floor beams

Lattice Beams:lattice beam mezzanine floor system

Metsec lattice joists offer a simple solution for the construction of both conventional and mezzanine floors due to their excellent strength to weight ratio. This means that a typical lattice steel joist can weigh up to 50% less than their hot rolled counterparts whilst spanning much further than timber joist alternatives.

Of great importance to the designer is the fact that the internal space can be optimised by passing services through the web of the lattice joists rather than having to suspend them underneath causing a significant loss of headroom.

Similarly, the ability to insert flush fitting timber sections into the top and bottom chords of the steel beam offers a simple medium for the fastening of floor decking and/or plasterboard ceilings.

In addition to the direct reduction of the environmental footprint of a construction project by virtue of their lighter weight, lattice beams can also help to reduce the environmental footprint of the project by using off-site fabrication to speed up the construction process of the floor as the lighter steel beam sections can generally be transported and handled more efficiently on site.

Lattice Beams : lattice beam floor joist

Metsec parallel floor beams at 600mm centres with the floor decking nailed to the top chord and two layers of plasterboard to the bottom chord.Lighter than hot rolled steel beams with the ability to span much further than timber joists.
