Over the years, we have built a wealth of expertise to become a Centre of Excellence.

The type of roof truss required for a particular product is dependent on the building structure and our team of designers work with technical teams, architects and contractors to ensure the right fit for their project. With over 30 years experience in truss design, we are experts in creating innovative solutions which are both cost effective and utilise space.

Spanning up to 8 metres, Howe Girder trusses are used as a support for other trusses or loose infill.
