BB Truss & Timber roof trusses are backed by over 40 years of engineering research and development by Multinail Australia. Our manufacturing capacity allows us to build and delivery trusses up to 20m in length and 3.8m in height – saving our customers time and money on installation while using a high-quality product. In addition, any custom, one-off roof shapes and designs are easily visualised with our accurate 3D modelling software.
