Whitewood Timber
6×3 whitewood, 150 by 75 mm, is the general purpose beam: trimmers around openings, purlins in a cut roof, ridge boards, and lintels over short internal spans. Strength-graded to C24 and kiln-dried below 22% moisture content, it is supplied with the certification needed for sign-off on regulated work. Lengths run from 4.2 m to 5.4 m. Stocked in our warehouse for delivery across Ireland.
Why Whitewood?
This is the first section in the range with enough substance to be a beam rather than a joist. The 75 mm thickness is what does it: a thick section resists twisting under load in a way a 44 mm board cannot, which is exactly what you need where rafters or joists hang off it. A 5.4 m length weighs around 29 kg, so plan a two-person lift or a prop.
Installation guidance
Give a beam full bearing at both ends, at least 100 mm onto masonry with a spreader or padstone under it where the load is real. Hang joists and rafters off it with proprietary hangers rather than skew nails, and get the hanger seated tight against the beam face before fixing. Do not notch a beam of this section anywhere along its length; if a service has to cross, run it under and box it in.
Finishing & maintenance
Purlins and trimmers in a roof stay dry once the covering is on, and untreated timber is right for that. Anything in an open structure, a carport or a porch, or bearing into an exposed wall, should be the treated equivalent from our C24 treated timber range. Keep a beam flat and fully supported in storage and never stand it on end against a wall. For longer spans, compare the 7×3 and 9×3 in our C24 timber range. To compare sawn and treated sizes side by side, see our construction timber page.
