Finnish timber
Finnish timber is a softwood from **northern Finnish pine and spruce graded C24 and C30 to EN 14081**, kiln-dried and PEFC/FSC certified. Available in 5×10, 7.5×15, and 10×10 cm sections at 3 to 6 m lengths — the structural standard for Riyadh villa roof trusses, priced SAR 24–50 per piece.
What is Finnish timber?
Finnish timber is a softwood milled from Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) grown in northern Finnish forests, graded C24 or C30 under European standard EN 14081. It ships into Saudi Arabia in large sections up to 10×10 cm and lengths to 6 m for major structural framing work.
Finnish forests are managed on 60–80 year rotation cycles, allowing timber to grow slowly and develop high density between 460 and 520 kg/m³ — above Swedish equivalents. The C30 grade carries 30 N/mm² bending strength, the highest among northern softwoods available in Saudi Arabia.
Finnish timber ships with PEFC and FSC chain-of-custody certificates and the European CE mark. Each piece carries the C24 or C30 grade stamp and mill identification, with full certificate of origin from the Finnish mill via Helsinki or Rauma ports.
Why is Finnish timber chosen for major structural work?
Finnish timber ships at C30 grade — 30 N/mm² bending strength and 460–520 kg/m³ density — with large sections to 10×10 cm and lengths to 6 m available. This makes it the optimal choice for trusses spanning 4–5 m and exposed-roof framing in premium villas, where Swedish C24 reaches its span limit.
Finland is the second largest engineered-timber exporter in northern Europe after Sweden, producing over 12 million m³ annually per Luke (the Finnish Natural Resources Institute). This sustains continuous supply of large sections required by Vision 2030 mega-project structural specifications.
In premium Olaya and Al Malqa villas, Finnish timber is selected for exposed gable ceilings because the golden wood tone and small knots present a clean appearance acceptable for visible decor without overlay or cladding required to hide imperfections.
What are the specifications of Finnish structural timber?
Finnish timber ships at C24 or C30 to EN 14081, bending strength 24–30 N/mm², density 460–520 kg/m³, moisture 12–18%. Sections 5×10, 7.5×15, and 10×10 cm at 3, 4, 5, and 6 m lengths, with PEFC, FSC, CE marks and SBC 301 conformity, priced SAR 24–50 per piece.

What are the construction applications of Finnish timber?
Finnish timber serves five core applications: large structural trusses, exposed roof framing, structural load-bearing walls, large pergola posts, and structural lintels. The C30 grade makes it the strongest northern softwood available in Saudi Arabia, suited to engineered structural specifications.
- 01
Large structural trusses
Truss top chords spanning 4–5 m in premium villa halls and rest houses, in 7.5×15 cm at C30 grade to carry high roof loads and live weather loads.
- 02
Exposed roof framing
Visible gable-roof rafters in 10×10 cm section for villas with rustic-style decor, oil-finished to highlight the natural golden grain of the timber.
- 03
Structural load-bearing walls
Load-bearing wall studs in multi-storey residential buildings, in 5×10 cm at 40 cm centres, sized to engineer's structural calculation for vertical load.
- 04
Large pergola and patio posts
Vertical posts for pergolas at 4–5 m height in large gardens and resorts, in 10×10 cm with galvanised metal post anchors at the base for stability.
- 05
Structural lintels for wide openings
Top lintels for openings 3–4 m wide in commercial buildings, in 7.5×15 cm at C30 grade to distribute vertical loads above the unsupported span.
What is the difference between Finnish and Swedish timber?
Finnish ships at C24/C30 grade, 460–520 kg/m³ density, sections to 10×10 cm and lengths to 6 m. Swedish ships at C24 only, 450–500 kg/m³, sections to 5×10 cm and lengths to 3.9 m. Finnish carries 20% more load capacity; Swedish is 10–15% cheaper for standard work.
Finnish is the choice for large structural trusses and exposed ceilings; Swedish is the choice for standard framing and non-visible work. Total project cost difference runs 5–8% on a typical villa — justified by Finnish's higher structural performance for large halls and engineered span requirements.

When do I choose Finnish timber over Swedish or Canadian?
Choose Finnish for trusses spanning 4–5 m, exposed roof framing, large 10×10 cm sections, or 5–6 m lengths. Swedish suits standard framing; Canadian suits trusses beyond 5 m or rustic decor with natural amber-brown timber colour. Finnish is the only EN 14081 C30 option in Saudi Arabia.
For C30 grade, Finnish remains the only available option among structural timbers in the Saudi market. Canadian is graded NLGA No.1 (approximately equivalent to C24), so engineer-specified C30 work has no substitute outside Finnish supply for the relevant load applications.
How is Finnish timber stored and installed?
Stack Finnish timber on stickers every 70 cm, 15–20 cm off the ground in a shaded area. Acclimatise 3–5 days as for Swedish. Fix with 100–150 mm nails on large sections, or bolted metal connectors for trusses requiring engineered structural connection at the joint.
Large 10×10 cm sections at 6 m require flatbed transport at least 7 m long with homogeneous loads grouped together. Site lifting requires a forklift to prevent back injury given the high single-piece weight — manual handling is not advisable above 5×10 cm sections.
On exposed trusses, select pieces with the lowest knot count and finish with a clear natural oil or satin varnish that highlights the wood grain. Use galvanised black-oxide nails to prevent visible nail heads from showing on the finished decorative ceiling surface.
Is Finnish timber approved under the Saudi Building Code?
Finnish timber is approved under SBC 301 structural requirements for load-bearing work, carrying the C24 or C30 grade stamp under EN 14081, the European CE mark, and PEFC/FSC chain-of-custody certificates. Accepted on green-building submissions (Mostadam, LEED) and major government projects without additional qualification.
Each shipment arrives with mill certificate of origin, stress, density, and moisture test reports, shipping invoice from Helsinki or Rauma port, and container manifest. Documentation suffices for engineer review on all Saudi villa and commercial-building projects under municipal authority review.
Which Saudi projects use Finnish timber?
Finnish timber is used on Vision 2030 projects including NEOM, Red Sea, Qiddiya, and Diriyah, in premium villas across Al Olaya, Al Malqa, and Al Yasmin, in boutique hotels in Old Diriyah, and in AlUla and Al Baha resorts for structural and exposed roof trusses.
- Vision 2030 mega-projects: NEOM, Red Sea, Qiddiya, Diriyah — large administrative-building trusses and exposed-roof framing.
- Premium villas in Al Olaya, Al Malqa, Al Yasmin — large-hall trusses and exposed gable ceilings.
- Boutique hotels in Old Diriyah — structural lintels and load-bearing frames in heritage-style buildings.
- AlUla and Al Baha resorts — large pergolas and 4–5 m height patio posts across leisure courtyards.
What are common questions about Finnish timber?
**50 pieces** for small sections and 20 pieces for large 10×10 cm sections is the effective delivery minimum. Smaller orders pick up from our Olaya yard. Delivery within 2–4 working days from weekly stock to most Riyadh districts.
**C30 carries 30 N/mm² bending strength** with about 1400 kg/m³ effective density; C24 carries 24 N/mm². C30 is used for trusses ≥ 4 m span, C24 for standard framing. Per-piece price runs 10–15% higher for C30 versus C24 grade in equivalent sections.
Not fully equivalent. Glulam carries **GL24h–GL32h grades** at 24–32 N/mm², made from glued laminations and more dimensionally stable for very large spans (≥ 7 m). Finnish C30 is solid-piece, cheaper for spans up to 5 m where glulam is over-specified.
Yes — Finnish timber arrives with **PEFC/FI-1002 and FSC C002387 chain-of-custody certificates** for sustainable forest management. Certificates are required for green-building submissions (Saudi Mostadam, LEED) and ship with every batch without additional charge.
Yes, especially because of its **low knot ratio (≤ 15% in C30)**. Finnish is selected for exposed gable ceilings in villa main halls and majlis rooms, finished with natural oil or satin varnish to highlight the natural golden grain of the wood.
Standard 5×10 and 7.5×15 cm sections ship from weekly stock within **2–4 days**. Large 10×10 cm sections at 6 m may require special order with a 50-piece minimum and 3–4 weeks lead time from Helsinki port to Riyadh delivery.
No — Finnish is **20–30% cheaper than Canadian** at equivalent C24 grade. Finnish runs SAR 24–50 per piece; Canadian runs SAR 30–75. Finnish is the better economical choice for projects without structural span requirements beyond 5 m or the Canadian timber's natural amber-brown colour.
