Swedish timber 3.9 metres
Swedish timber at 3.9 m is **northern Scots pine graded C24 to EN 14081**, kiln-dried with PEFC and CE certification. Specified for large halls, long-span trusses, and wide corridors in 4×6, 5×7.5, and 5×10 cm sections at SAR 28–48 per piece — daily Riyadh stock from the Swedish standard production line.
What is Swedish timber at 3.9 m length?
Swedish timber at 3.9 m is northern Scots pine cut to a 3.90 m standard length, graded C24 to EN 14081 with PEFC and CE certification. This is the longest length in the Swedish standard production line, specified for large halls, long-span trusses, and roof spans exceeding 3 metres between supports without splice joints.
The 3.9 m length removes structural splice joints in trusses spanning 3–3.7 m — the optimal length for ceiling joists in large rooms across premium villas and wide rest houses. Splices in structural trusses force expensive metal connectors, which 3.9 m makes unnecessary at engineer-specified loads.
Each piece carries the C24 grade stamp and batch number, shipping with mill certificate of origin from Sweden. Kiln-drying to 12–18% moisture ensures dimensional stability after installation — critical in long members where uneven shrinkage causes visible bow across the unsupported span.
Why is the 3.9 m length specified for trusses and large halls?
The 3.9 m length covers truss spans up to 3.7 m between supports without structural splices. Splice-free trusses preserve full C24 structural performance and remove the cost of metal connector plates and additional bracing required at every splice connection in shorter-length alternatives.
Large halls in premium villas (main living, dining, majlis) require ceiling spans of 3–4 m, and the 3.9 m length covers them with one continuous member. This preserves the clean appearance of exposed gable ceilings and accelerates installation versus splice-and-brace alternatives.
Wide corridors in boutique hotels and premium rest houses need ceiling joists 3.5–3.8 m long — the 3.9 m length suits these with 10–30 cm allowance for fixing into both bearing walls. This is the standard length for 3.5 m wide corridors in premium residential and hospitality buildings.
What are the specifications of Swedish timber at 3.9 m?
Swedish timber at 3.9 m ships at C24 grade to EN 14081, bending strength 24 N/mm², density 450–500 kg/m³, moisture 12–18%. Sections 4×6, 5×7.5, and 5×10 cm at SAR 28–48 per piece, with PEFC, CE certifications and SBC 301 structural conformity for residential and commercial use.

What are the applications of Swedish timber at 3.9 m?
The 3.9 m length serves five core applications: large-hall trusses, wide-corridor joists, long pergola posts, tall scaffolding uprights, and wide-opening lintels. This is the standard length for structural work with large spans in premium residential, hospitality, and resort projects.
- 01
Large-hall trusses
Top chords for trusses spanning 3–3.7 m in premium villa main halls and majlis rooms, in 7.5×15 cm section to carry exposed gable roof loads.
- 02
Wide-corridor ceiling joists
Ceiling joists for 3–3.5 m wide corridors in boutique hotels, resorts, and private hospitals — 5×10 cm at 40 cm centres for distributed load.
- 03
Long pergola and patio posts
Vertical posts for timber pergolas at 3.7 m height in large villa gardens and rest houses, in 10×10 cm section with galvanised metal post bases.
- 04
Tall scaffolding uprights
Timber scaffolding uprights for finishing trades at 3.5–3.8 m heights, in 5×10 cm section with diagonal bracing every 1.2 m for 250 kg working load.
- 05
Wide-opening lintels
Top lintels for panoramic doors and large windows above 3 m wide, in 7.5×15 cm section to distribute vertical loads across the unsupported opening width.
What is the difference between Swedish 3.9 m and Canadian timber at the same length?
Swedish 3.9 m is 450–500 kg/m³ at C24 to EN 14081, daily-stocked at SAR 28–48 per piece. Canadian (Douglas fir) at 3.9 m is 480–550 kg/m³ at NLGA No.1, on-order at SAR 45–75. Canadian carries 20% more load; Swedish is 30% cheaper for standard structural use.
Swedish 3.9 m is the working choice for trusses and halls in Saudi villas because it ships from stock and meets C24. Canadian is specified on order for trusses spanning ≥ 4 m and exposed ceilings requiring the natural amber-brown timber colour favoured in rustic-style decor.
| Attribute | Swedish 3.9 m | Canadian 3.9 m |

When do I choose Swedish timber 3.9 m over shorter lengths?
Choose 3.9 m when truss span is between 3 and 3.7 m, pergola height ≥ 3.5 m, or opening width ≥ 3 m. Shorter lengths force structural splice joints in these conditions, and splices require metal connector reinforcement that adds 15–20% to total framing cost.
For spans 3.7–4.5 m, substitute Swedish C24 with Finnish C30 timber, which carries 30 N/mm² bending strength. For spans beyond 4.5 m, specify Canadian Douglas fir or engineered glulam to cover structural distances without intermediate columns disturbing the open-plan layout.
How is Swedish timber 3.9 m stored and installed?
Stack on stickers every 80 cm, 20 cm off the ground in a shaded, level area. Transport requires flatbeds at least 4.5 m long to prevent in-transit bending. Fix with 100–150 mm nails. Lift with at least two operatives to prevent member bow during installation under self-weight.
Long 3.9 m sections bow under gravity if stacked on only two supports — at least three supports (end-mid-end) are required to keep members straight. Vertical storage is prohibited because permanent bow develops within days, voiding the C24 structural grade.
In truss installation, fix to top and bottom plates with two nails at each intersection and add diagonal bracing every 1.2 m to resist lateral twist under load. Working at height requires stable scaffolding and operative safety lines for compliant installation procedures.
Is Swedish timber 3.9 m approved for load-bearing structural work?
Yes. Swedish timber at 3.9 m is approved under SBC 301 for load-bearing structural use, carrying the C24 grade stamp under EN 14081, the European CE mark, and PEFC certification. Truss and large-hall applications require structural calculations from a licensed engineer attached to batch documents at municipal review.
Each shipment ships with mill certificate of origin, stress and bending test reports, density and moisture reports, shipping invoice, and container manifest. These documents satisfy engineer review under SBC 301 projects, with stamped consultant copies provided for government and mega-project work on request.

- AlUla and Al Baha resorts — large pergolas and outdoor canopies across leisure-area courtyards.
What are common questions about Swedish timber 3.9 m?
**40 pieces** — about a fifth of a trailer load — is the effective minimum for delivery. Smaller orders ship from our Olaya yard or piggyback on an active project shipment near the contractor's site, dispatched within 24–48 hours of order confirmation.
Yes — actual length is 3.90 m at **±5 mm tolerance** after kiln-drying. This precision allows direct cutting of 3.7 m truss top chords with a 20 cm allowance for fixing into both bearing walls without on-site re-measurement.
Maximum span is **3.7 m between supports** in 7.5×15 cm section at C24 grade. For longer spans, choose Finnish C30 or Canadian timber. Span calculation depends on roof self-weight and engineer-specified live loads in the project schedule.
Suitable for exposed gable ceilings after **finishing with a clear sealer** that highlights the natural pine grain. For rustic decor in golden-brown wood tones, Canadian timber is preferred for its naturally darker hue without staining required.
Transport uses **flatbed trucks at least 4.5 m long** to prevent overhang violations. Smaller orders under 40 pieces ship on medium trucks with additional support brackets, with delivery within 24–48 hours of order confirmation across Riyadh.
Yes — accepts cutting to **±2 mm tolerance** through our cutting department. The service is available for all sections, with cut pieces delivered numbered and bundled per cut list to reduce on-site labour and accelerate truss installation.
Swedish standard production runs at 3, 3.3, and 3.9 m only. The 4 m length is available in **Finnish and Russian timber** at different specs (Finnish C24/C30, Russian C18/C24 to GOST 8486). For exact 4 m, we supply Finnish at SAR 30–50 per piece.
