What is a DuoSpan 99 - 90 Degree Bracket made from? A DuoSpan 99 - 90 degree bracket kit consists of the support bracket set to 90 degrees and the DuoSpan screws, which are designed to correctly and securely fit your brackets. The bracket is made from robust aluminium for durability and strength, whilst the DuoSpan scores are constructed from strong stainless steel. They have also been coated with a cathodic barrier to minimise any erosion when coming into contact with different metals. What's the difference between DuoSpan 51 and DuoSpan 99? Each one constructs a comprehensive subframe decking system. The two differing numbers refer to the best locations each frame will perform and the relevant weights they can hold. DuoSpan 99 is suitable for use 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.

DuoSpan is an aluminium joist system designed to provide a solid and long-lasting foundation for your decking or cladding. Its components make up the innovative and durable framework for your Millboard product. This makes installing decking or cladding an easy solution. It also has the flexibility to work around different shapes, sizes, heights, and challenges. Can I use any fittings with a DuoSpan 99 - 90 Degree Bracket? The DuoSpan range of fixtures has been purposely designed to work in conjunction with the rest of the DuoSpan range and Plas-Por subframes from Millboard. This means the DuoSpan hex-head screws will perfectly fit the pre-drilled holes to provide a secure and easy installation.
