In timber construction, a purlin or rafter is the term used for the wooden beam in a roof structure that runs along the length of the roof trusses. The purlins span from one truss to another and support the roof. They are also known as beams or rafters. Girders are often sawn out of pine and can have dimensions of 8×15, 8×20, 10×20, or 10×25 cm.

Oak purlins air-dried

Purlins are typically sawn out of pinewood, but it is also possible to saw them out of oak logs. It is important that the oak rafters are dried before application. Green oak purlins can warp due to the high moisture content in the wood. Therefore, it is recommended to use oak wood that have been air-dried. Air-drying oak rafters reduces the moisture content in the wood over time, resulting in wood with minimal potential for warping. An additional advantage is that the oak wood develops a beautiful appearance through natural seasoning.

The air-dried oak purlins and rafters are suitable for indoor applications.

French oak rafters

Our stock of oak rafters originates from France, where the oak forests have been responsibly managed for centuries. Each year, a controlled number of trees are harvested due to the careful stewardship. French oak wood is renowned for its high quality, thanks to the favorable continental climate and soil conditions that provide ideal natural growth conditions for the oak trees.

Seasoned oak rafters

Our oak rafters are being air dried at our yard, exposed to rain, wind, and sunshine, resulting in a beautiful seasoned surface. Over the course of several years, the rafters develop an appealing patina, adding to their character.

Oak stair steps with an aged look

In addition to their use as structural timber, the wood can also be used for oak steps. A robust oak staircase with treads measuring 20 or 25 cm wide, for example, adds character. An oak staircase is highly durable and resistant to wear and tear, suitable for both rustic and modern interiors. Thanks to the weathered look from the greying process, the staircase has an old, weathered appearance. A substantial rafter can also serve well as an oak stair stringer.
