Boxspan Roof Frames

Roof frames, rafters, roof beams & lintels

Boxspan roof frames and rafters are suitable for use with both steel and timber framed homes. Boxspan is extremely efficient in roof framing. Long spans and light weight make architectural  such as cathedral ceilings, exposed trusses and roomy lofts more feasible than ever. Boxspan is also used in commercial roof applications such as schools.

Why Boxspan for roofs?

  • Handling Boxspan rafters is easier as they are lighter than timber rafters.
  • As blocking is not required, even for long spans it leaves a tidy finish for exposed rafters.
  • Long-spanning Boxspan reduces the need for structural beams giving you a straight ceiling with fewer bulkheads.
  • Boxspan roof frames are supplied as a complete, designed system to strict deflection criteria.
  • Boxspan can reach a similar span for less depth than timber.
