If the depth of the load bearing beams under the deck become a problem this can be reduced by using a truss. The stiffness is supplied by the handrails and this allows significant reductions in the thickness of the deck.
Trusses also have an attractive appearance and can add to the appeal of a bridge. The site above on the Cumbria Coastal Footpath was extremely remote and the reduced weight of the trusses helped get the structure to the site. Many clients find the opportunity to use strong colours adds positively to the effect of their schemes The light and airy feeling of the truss plus the reduced depth of the deck makes them an attractive proposition
We can supply all types of truss (there are many variations). Our most usual forms are Vierendeel, Pratt, Warren and Modified Pratt
