Timber Floor and Rafter Trusses by Pryda

Product/Service Name

Pryda Floor and Rafter Trusses: Pryda Longreach trusses are manufactured using timber webs and chords for maximum stiffness - While the Pryda Span trusses are prefabricated using high strength steel diagonal webs for lightweight and economy benefits.

Design Benefits

• Assured performance: Pryda floor and rafter truss systems have been used with outstanding results for over 10 years by designers and builders.
• Design versatility: The long span capacity up to 8 metres or more offers functional design freedom and can eliminate the need for interior support walls and beams.
• Depths to suit: Wide range of standard depths available from 200 to 450mm - or can be manufactured specifically for a particular project.
• Limited space: Designs can accommodate large spans in restricted height applications.
• Cost effective: Timber grade in chords is selected to suit the design requirements of each individual project to provide the most cost effective system.
• Larger spans at low cost: With all-timber trusses the span capacity increases significantly as the truss depth increases at little extra cost.
• Commercial applications: Pryda floor trusses not only accommodate domestic loads but may also be designed for commercial applications including offices, schools, hospitals and function areas.
• Designed to order: Stiffness required, depth, timber grades and sizes can be varied to suit any individual job requirements. Computer designed for optimal performance efficiency and lowest material cost.
• Wide range of end supports: Standard end support types suit any structural connection required including steel beams, waling plates and other framing connections.
• Extra stiffness in floors: Stiffer than other floor systems with established dynamic limits to ensure rigidity and to overcome springiness and bounce.
• Accommodates large ducts: Large rectangular ducts to 500mm wide can fit within the standard design and special duct routing within rows of trusses can be incorporated.
• Dimensionally stable: Fully kiln-dried timber ensures stability, free from movement due to shrinkage.

Construction Benefits

• Easy to install: Truss end support connections are prefabricated to fit. No cutting or notching will minimize the possibility of mistakes.
• Ease of access: Flexible ducting, electrical wiring and electronic data cabling can be easily run between the truss webs.
• No cutting holes: Simplifies the work of following trades. Plumbing, ventilation ducts and conduits can be simply attached to the webs or chords without any cutting or drilling holes.
• Faster installation: Quicker installation times provide the opportunity to reduce construction costs.
• Stable platform during construction: The wide chord flanges are more stable for tradesmen moving around the elevated areas on a job. 
• Lightweight: Trusses are much lighter than solid timber sections. Much easier to handle and lift on site.
• Floor set-down feature: A section of Longreach floor trusses can be manufactured with a reduced depth to accommodate tiled wet areas.
• Consistent depth: Longreach floor trusses can be manufactured to the same depth for the entire project to eliminate uneven ceiling levels at little extra cost, regardless of the variations in spans.
• Robust construction: More robust than other prefabricated systems, and more able to resist the effects of mishandling.
