There are two basic types of truss: The pitched truss, or common truss, is characterized by its triangular shape. It is most often used for roof construction. Some common trusses are named according to their “web configuration”. The chord size and web configuration are determined by span, load and spacing.
What are open web floor joists?
Open-web floor trusses provide superior cantilever distances. Far greater than EWP and conventional framing. Cantilevers can include built-in details such as dropped top chords for balcony decking.

What are open joists?
Open web wood hybrid joists are made of an I-section and an open web truss section, located in the centre of the span, with wooden diagonals for superior sturdiness. This open-web truss section offers much greater flexibility for accommodating air ducts, electrical wiring and plumbing.
