Agricultural Timber Purlins are the horizontal structural timbers used in a load bearing situation in the roof construction of many agricultural and farm buildings.

Since July 2014 the EU Construction Products Regulation (CPR) came into effect which requires the timber used in these situations to meet EU standards on structural timber.

All agricultural timber purlins must be strength graded to either C16 or C24 depending on section and load requirement.

The strength grading of timbers is carried out either by visual grading or by machine to British Standard EN 14081 and the timbers are clearly marked with a stamp to show the strength class individual purlins have been graded to.

Graded agricultural timber purlins are CE marked enabling suppliers to issue customers with a Declaration of Performance (DoP) which clearly defines the  criteria used in the grading process.

At Brookridge timber we stock a wide range of high quality pressure treated timber purlins all available ex stock and on short lead times.

The Micronised  high pressure treatment used on our timber purlins to protect them from rot and insect attack has achieved Greenguard Certification. This means that it has met stringent standards for low VOC emissions making it suitable for use in sensitive environments and therefore ideal for a building constructed to house livestock.

At Brookridge Timber as well as timber purlins, we stock the complete range of the other timber components required to construct an agricultural building and customers are able to order exact quantities to complete any project.  Details of these products are available on this website.
