Overview
Trusses are an extremely effective form of structures, whether decorative with exposed or hidden plates and appearance with basic connections. Appearance grade systems can be designed and fabricated from sawn timber as well as Glulam, and in non appearance applied, LVL or sawn timber can be adopted.
Design considerations can have a cost implication, therefore our years of experience can provide the most efficient and cost effective form.
