Members are joined with steel nail plate fasteners engineered to provide a structural frame to support the roof fabric, ceilings and/or floors together with other features, such as dormer windows and attic roofs. Combined with other ancillary mechanisms, they are used to construct trussed rafter roofs on a wide range of building types.
In today's competitive market, trussed rafters stand alone as a sophisticated and highly engineered timber product, with complex design and superior creation reinforced by high production standards.
Compared with other methods of roof construction, trussed rafters represent the most cost-effective and flexible design option available.

RiR trusses now account for about 30% of all trusses and this figure is likely to increase as land prices continue to rise. Increasing comfortable space within the roof is a cost-effective means of providing more rooms on building plots where space is at a premium. RiR trusses are of specific interest to small to medium-sized builders for whom attic conversions deliver a profitable source of revenue.
Trussed rafters can accommodate nearly any shape. They enable architects to give their inspiration full reign, providing visually stunning effects when used to produce vaulted and multi-level ceilings.
Added to this is their speed of creation which delivers real on-site labour cost savings, particularly when ground-level erection methods can be used. In the non-domestic market, trussed rafters also provide a cost-effective roofing solution for commercial, agricultural and industrial buildings.
