All frame and truss optimized FRAMA machines can produce lattice trusses as standard.
The lattice truss is a cost-effective way of spanning larger areas and the truss depth can be varied to achieve different spans. Howick’s truss system offers a floor truss with greater spans and lighter weight than timber alternatives, and can be produced on a just in time basis. The FRAMA 4200 dedicated truss system allows for greater spans with thinner material than the equivalent joist made using a standard framing profile.

* The amount of steel used to construct a lattice floor joist only marginally increases as the joist depth becomes greater. Generally, only the extra height of the joist (x2) is the actual extra steel used and the number of fastenings actually reduces as less diagonal webs are used. This means very large gains in strength can be made, with no increase in weight or cost.
