Solid Structural Timber: C14, C24, Impregnated and KVH

Solid timber is the essential base material for any sound and durable building structure. At Dartank.com , we supply a carefully selected range of solid timbers that meet the most demanding strength-grading standards.

This category brings together our certified solutions for framing, joisting and roof structures:

  • Graded sawn timber (C14 – C24): Ideal for traditional roof structures and structural work.
  • Impregnated Timber: Treated to withstand moisture and biological attack (Use Class 2 or 3), perfect for exposed environments.
  • KVH Timber (Konstruktionsvollholz): High-quality finger-jointed solid timber, kiln-dried to guarantee exceptional dimensional stability and a planed finish.

All our timber comes from sustainably managed forests and is selected for its low moisture content and straightness. Order your standard or bespoke sections on Dartank.com, with logistics suited to extra-long materials.

Frequently asked questions

Everything you need to know before ordering. Another question? Contact us.

C24 timber is classic sawn timber that has been strength-graded. KVH is solid timber too, but it is kiln-dried (to around 15% moisture content) and often finger-jointed along its length, which makes it far more stable, far straighter and much less prone to splitting than traditional sawn timber.
Treated timber should be used for any structure exposed to moisture or to insect attack. For a conventional roof structure, class 2 treatment is sufficient. For components in occasional contact with water, choose class 3 pressure-treated timber.
