Description
Our Bullnose Common Rafters are machined from premium-grade timber and shaped to a true, consistent radius, so the curve runs clean and even across the verandah.
Sizes
Timber length: 1.5m, 1.8m, 2.1m, 2.4m, 2.7m, 3.0m
Standard radius: 300mm and 400mm
Special radius: 350mm, 450mm, 500mm, 550mm
Timber size: 90 × 42mm, 120 × 42mm, 140 × 42mm
Key features
- Australian-made in our Bayswater workshop, machined to a consistent shape and finish
- Cut to the radius and length your roof requires
- Suited to heritage restoration and period-style residential work
Custom radii and lengths are available — send us the measurements of your existing roof and we will match them.
How to measure the radius of your existing rafter
The radius is measured on the top edge of the rafter. On a complete bullnose rafter the curve is a quarter circle, so the height of the curve equals the radius (H = R).
- Lay the rafter on its side on a flat floor.
- Run a straight edge along the top edge of the straight section, out past the curve.
- Measure straight down from that line to the end of the curve on the top edge. That measurement is your radius.
- Measure the timber section (depth × thickness) on the straight part of the rafter.
If the end of your rafter is broken, rotted or cut short, the height will read less than the true radius, and older hand-cut rafters often don't follow a perfect arc. Trace the curved end onto paper or cardboard and send us a photo with a tape measure in shot, or send us a short sample. We hold templates for dozens of rafter profiles and will match it.
Before you order — how will these rafters be used?
Timber rafters form part of a roof structure. We shape rafters to the radius, length and section you specify. The section size, grade, spacing and span for your roof must be determined by your builder or engineer, and must comply with the National Construction Code and the relevant Australian Standards for your project and site.
Our timber is preservative-treated for exterior use above ground and is not supplied stress-graded. We manufacture to the specification you give us. Use your own engineer, or we can introduce you to one who will work with you directly.
Prime all faces, including cut ends, before installation.
