Straight solid wood post h 120cm section 70x70mm - 4 species for balustrade

This straight post for balustrades and handrails measures 120 cm in height with a square section of 70x70 mm. It is available in four species — douglas, fir, pine or beech — to suit each application and budget. Sold per unit, it allows a fully bespoke balustrade to be assembled or an intermediate post to be added to an existing kit.

The choice of species directly determines the intended use: beech is reserved for indoor use (sensitive to moisture), fir and pine are suitable for indoor and sheltered outdoor use with treatment, douglas is the most suitable species for exposed outdoor use thanks to its natural class 3 resistance. All are supplied raw and untreated, ready to receive the finish of your choice.

Installation advice

Choosing the species according to use: For an interior staircase or a mezzanine, beech gives the cleanest finishes (fine grain, pinkish white). Fir and pine are more economical and perfectly suited for indoor use. For a covered terrace or a sheltered outdoor staircase, choose douglas — its natural resistance (class 3) allows it to hold up for several years without intensive treatment, even in moderately exposed conditions.

Fixing: Space the posts no more than 1.5 m apart. Fix each post with a floor plate suited to the substrate. Check the vertical alignment with a spirit level before final tightening. Pre-drill the joints at Ø4 mm before the final screwing to avoid splitting the wood in square section.

Maintenance and protection

For indoor use, apply a varnish or oil-wax before putting into service. For sheltered outdoor use with douglas, renew the exterior stain or oil every 2 to 3 years. Douglas used outdoors without treatment will naturally turn grey but retains its mechanical properties for several years. To maintain the original colour, apply an exterior wood saturating oil annually.

WoodUp tip

What to know before buying: this post is supplied raw without pre-drilling — the hole positions depend on your specific configuration (mounting plate height, rail position). Mark the drill points in pencil after a dry fit before any final fixing. If douglas is intended for outdoor use, it must receive a suitable finish (class 3 oil or stain) before installation. For indoor use, all species are suitable; choose the species to match the rest of the balustrade for a harmonious result.

Frequently asked questions

Which species should be chosen for an outdoor terrace balustrade?

Douglas is the best choice for exposed outdoor use among the 4 available species. Its natural class 3 resistance allows it to withstand the elements without curative treatment. Fir and pine are reserved for indoor use. Outdoors, use douglas only. For sheltered outdoor use with douglas, regular renewal is required. Beech must be entirely excluded for outdoor use — it deteriorates rapidly in damp conditions.

Is this 70x70mm post compatible with WoodUp straight spindles?

Yes. The straight spindles Straight solid wood spindle, straight slats Straight balustrade slat 95cm and moulded slats Moulded solid wood slat from the WoodUp range are dimensioned to fit between posts of 70x70mm section. The bottom rails Solid wood bottom rail and handrails Moulded solid wood handrail also bear against this standard section.

Can this post be cut down if the height is too great?

Yes. All four species can be easily cut with a mitre saw or a circular saw. If you reduce the height of the post, recalculate the position of the assembly drill holes accordingly. Sand the cut edge before applying the finish.

How many posts are needed for a 2-metre balustrade?

For a 2 m span, you need a minimum of 2 posts — one at each end. If one end is anchored to a wall or a stringer, a single free-standing post is sufficient. For spans of 3 m and above, add an intermediate post every 1.5 m.

Should this post be treated before installation, even if it is douglas?

Douglas is supplied raw and untreated. For outdoor use, apply an exterior oil or stain to all faces before installation, including cut edges. Class 3 douglas is naturally resistant to fungi and insects, but an annual surface treatment significantly extends its aesthetic lifespan and limits greying. For fir, pine and beech, a treatment appropriate to the intended use (indoor use only) is essential.

What is the difference between a straight post and a turned post for a balustrade?

The straight post (70x70 mm section, H 120cm) has sharp edges and a clean contemporary profile. The turned post is shaped on a lathe, with a more classic and traditional profile. Both have the same section and height, but the aesthetic differs considerably. Choose the straight post for a modern interior, the turned post for a classic-style staircase.
