What are the dimensions of the DuoSpan Aluminium Beam? The DuoSpan Aluminium Beam measures 63mm (W) x 136mm (D) x 3.6m (L) and fits perfectly with the DuoSpan 51 or DuoSpan 99 subframe foundations. It has been designed by industry experts and is fully compatible with the DuoSpan range. Made from tough aluminium, it provides strength and durability for your decking structure. What's the difference between DuoSpan 51 and DuoSpan 99? Each constructs a comprehensive subframe decking system. The two differing numbers refer to the best locations each frame will perform and the relevant weights it can hold. DuoSpan 99 is suited for use in areas over soft substrates, where the Plas-Pro can be driven into the ground or concreted over. DuoSpan 51 is better suited for roof terraces and ground-level terraces. To understand which DuoSpan option is suitable for your exterior structure, please speak to the team.
