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® 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. 

The beams are produced to controlled tolerances. Generally, beams are manufactured to exact length (up to 12.5 metres or longer by arrangement). Boxspan can be easily cut on site if necessary using simple tools such as a drop saw or circular saw with a friction blade. The wide range of brackets and accessories available with Boxspan makes it an easy substitute for timber in most applications.
