Douglas Fir Roof Timber by the m³ - Solid Wood Custom Sawing, Quote on Request

This product allows you to purchase solid douglas fir roof timber by the cubic metre, sourced directly from the forests of the Massif Central. Unlike rafters and posts sold per piece in standard sections, this offering is intended for projects requiring large volumes or specific sections not available in the catalogue. The price is set per m³ and the sawing is carried out to your dimensions.

Massif Central douglas fir is a structural timber recognised for its high mechanical qualities: bending resistance, moderate density (500-550 kg/m³) and natural class 3 durability. Sourced from sustainably managed forests, it is one of the most widely used species for traditional and contemporary roof framing in France.

Key points

✓ Massif Central Douglas Fir: benchmark French structural timber species, density 500-550 kg/m³
✓ Natural Class 3: durability without mandatory treatment for off-ground roof framing
✓ Custom sawing: sections and lengths defined to your own specification
✓ Sold by the m³: suited to large-volume projects, long spans and specific sections
✓ Quote only: price, lead time and availability confirmed according to volume and dimensions

For which project?

This m³ offering is suited to projects requiring large quantities: individual house roof frame, barn, agricultural shed, extension, large-span pergola. It is also suitable for sections not available in the catalogue (principal rafters, purlins, wall plates, rafters> 60mm). For small volumes in standard sections (60x40mm, 60x80mm), douglas fir rafters sold per piece are better suited and available immediately.

How to order?

Purchasing roof timber by the m³ is not available directly online. Prepare your cutting list (sections, lengths and quantities for each piece) and contact WoodUp by form or chat. A quote will be sent to you with the price per m³, the sawing lead time and delivery terms according to your volume and location. State your desired lead time and any site access constraints from your very first contact.

Installation advice

On receipt of the delivery, check the cutting list (sections and lengths) before unloading and immediately note any discrepancy on the delivery note. Rough-sawn douglas fir may show natural colour variations between pieces from different batches: this is a normal characteristic of wood and has no bearing on its mechanical properties.

Store pieces flat, stacked with air gaps on bearers spaced no more than 80 cm apart, sheltered from direct rain but without an impermeable sheet so that air can circulate. Freshly sawn timber continues to dry on site: allow for possible moisture uptake during installation in summer if the pieces have been stored in dry conditions. Prepare your complete cutting list before contacting WoodUp: a precise cutting list avoids surplus and reduces transport costs.

Maintenance and protection

Solid class 3 douglas fir requires no mandatory treatment for a traditional roof frame with no ground contact. For visible exterior exposure (pergola, carport), a wood saturator or oil applied at the end of the build extends the preservation of the natural colour. Without treatment, douglas fir gradually turns grey over 12 to 24 months depending on exposure, without any loss of its mechanical properties.

For pieces in direct contact with the ground or standing water (buried posts, thresholds), natural class 3 is insufficient: class 4 autoclave or vacuum-impregnated treatment is essential. Please mention this requirement when requesting a quote.

WoodUp advice

What to know before buying: douglas fir is sold by the m³ — calculate the required volume accurately before ordering. The cross-section of the pieces directly determines bending resistance: for a 3m span, a minimum section of 63x150mm is generally recommended for rafters; consult the DTU 31.1 load tables for your configuration. Class 3 douglas fir can be used outdoors under cover without special treatment, but a preventive treatment extends the service life of joints exposed to moisture. Stainless steel fixings are mandatory for all exterior assemblies.

Frequently asked questions

What is the minimum order quantity for douglas fir roof timber by the m³?

There is no fixed minimum volume. Orders from 1 to 2 m³ can generally be processed: contact WoodUp specifying sections and lengths for confirmation. For small volumes in standard sections, per-piece rafters (60x40mm or 60x80mm) are available immediately with no sawing lead time.

Is the douglas fir sold by the m³ the same wood as the rafters sold per piece?

Yes, the same Massif Central douglas fir species. The difference lies in the packaging: per-piece rafters are available in fixed sections (60x40 and 60x80mm) and standard lengths (200 and 240cm). Ordering by the m³ allows you to specify custom sections and lengths to your own specification, for projects that the standard catalogue does not cover.

What is the lead time for a custom-sawn timber frame order?

The lead time depends on the volume, the sections requested and the sawmill schedule. Allow generally 2 to 4 weeks for a standard custom sawing order. State your desired lead time from the outset when requesting a quote so that WoodUp can confirm feasibility before any commitment.

Is delivery included in the price per m³ of douglas fir roof timber?

No. Delivery is calculated separately based on weight, volume and delivery distance, by flatbed lorry or crane lorry depending on the site configuration. Please provide your address and any access constraints (width, height, gradient) when requesting a quote to obtain a full delivery cost.

Can I order autoclave-treated douglas fir for buried posts?

Untreated douglas fir is class 3: suitable for roof framing with no ground contact. For pieces in direct contact with the ground or standing water (buried posts, bottom plates), class 4 autoclave or vacuum-impregnated treatment is required. Please state this explicitly when requesting a quote.
