This was a nex Gen decking installation done at Perth. The colour that was used is Rosewood from Nex Gen Decking.
All the framework is treated pine with the joists spaced out at 400mm instead of your normal 450mm per the manufacturers instruction.
All Nex Gen products have a first 20 year no fade and performance warranty so you do not have to worry about any issues with the product colour or any warping and twisting issues.
