Truss Types
Open Web Joist - Truss Type: OWJ
Open Web Joist (OWJ) is a fabricated joist (truss).
They are manufactured from RHS steel that is welded together to form a structurally strong member.
All of Spanlift’s open web joists are manufactured to specific sizes which means that you can easily extend your building at any given time.
Spanlift’s trusses are uniquely manufactured and hot dip galvanised, which creates the ultimate structural frame.
Open web joist is a lightweight steel truss - consisting of parallel chords and a triangulated web system, proportioned to span between bearing parts. They provide stronger structural integrity by transferring the load to structural columns.
Designed specifically giving consideration to span, joist spacing, slope, live loads, dead loads, collated loads and wind uplift, etc.
Truss Types
Universal Beam Rafter - Truss Type: UB
Universal beam rafters are typically manufactured from the same type of material as the column.
Often people refer to UB (universal beam) as ‘H’ iron or ‘I’ beam.
At Spanlift, our UB rafters are hot dip galvanised ensuring servicability and protection.
Some common applications for UB rafters are:
> Architectural design
> Low clearance heights
> Odd shaped buildings
