Spantec Steel Beams

Boxspan is a roll formed beam manufactured from two “C” shaped sections of high tensile, zinc coated steel, mechanically locked together with a patented process.

The result – a 40-60% lighter beam with the strength of steel and the versatility of timber. This unique system provides the benefits of a full protective zinc coating on the inside and outside of the beam. 

Boxspan beams allow our customers to substitute timber in many structural applications such as sub-floors, decks and roof frames without the concern of termites.

Unique strength

Unlike other steel Rectangular Hollow Sections (RHS) Boxspan® has the unique qualities of having a double thickness flange and a single thickness web that effectively puts the strength where it needs to be.

The beam is strong with high torsional stability and is easy to use as it has similar dimensions to timber. In most applications Boxspan beams require less depth than timber to reach the same span.
