Straight solid wood post, 120 cm high, 70x70 mm section – 4 wood species for balustrades

This straight balustrade post is 120 cm high with a square 70x70 mm section. It is available in four wood species – Douglas fir, fir, pine or beech – to suit different uses and budgets. Sold individually, it lets you build a fully bespoke balustrade or add an intermediate post to an existing kit. A balustrade is also known as a guardrail.

The choice of wood species directly affects where the post can be used: beech is for indoor use only (it is sensitive to moisture); fir and pine are suitable indoors and in sheltered outdoor areas if treated; Douglas fir is the most suitable for exposed outdoor use thanks to its natural class 3 durability. All are supplied unfinished and untreated, ready for your chosen finish.

Installation tips

Choosing a wood species for its intended use: For an indoor staircase or mezzanine, beech gives the neatest finish (fine grain and a pinkish-white colour). Fir and pine are more economical and perfectly suited to indoor use. For a covered terrace or sheltered outdoor staircase, choose Douglas fir – its natural class 3 durability allows it to last for several years without intensive treatment, even with moderate exposure.

Fixing: Space the posts no more than 1.5 m apart. Secure each post with a floor-mounted base plate suited to the surface. Check that it is vertical with a spirit level before final tightening. Pre-drill the joints with a Ø4 mm bit before screwing to prevent the square-section timber from splitting.

Care and protection

Indoors, apply a protective floor varnish or hardwax oil before use. For sheltered outdoor use with Douglas fir, reapply exterior wood stain or oil every 2 to 3 years. Untreated Douglas fir outdoors greys naturally but retains its structural properties for several years. To preserve its original colour, apply an exterior wood-saturating oil annually.

WoodUp tip

Before you buy: this post is supplied unfinished, without pre-drilled holes – the hole positions depend on your specific layout (base plate height and rail positions). Mark the drilling points in pencil after a trial fit, before fixing anything permanently. If intended for outdoor use, Douglas fir must be given a suitable finish (class 3 oil or wood stain) before installation. All four wood species are suitable indoors; choose one that matches the rest of the balustrade for a harmonious look.

Frequently asked questions

Which wood species should I choose for an outdoor terrace balustrade?

Douglas fir is the best choice for exposed outdoor use among the four available wood species. Its natural class 3 durability helps it withstand the weather without remedial treatment. Fir and pine are for indoor use only. Outdoors, use Douglas fir exclusively. For sheltered outdoor use with Douglas fir, renew the finish regularly. Beech should never be used outdoors – it deteriorates quickly in damp conditions.

Is this 70x70 mm post compatible with WoodUp straight spindles?

Yes. The WoodUp range’s straight spindles Straight solid wood spindle, straight balusters Straight 95 cm balustrade baluster and moulded balusters Moulded solid wood baluster are sized to fit between posts with a 70x70 mm section. The bottom rails Solid wood bottom rail and handrails Moulded solid wood handrail also rest against this standard section.

Can this post be cut down if it is too tall?

Yes. All four wood species can easily be cut to size with a mitre saw or circular saw. If you shorten the post, recalculate the positions of the assembly 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 at least 2 posts – one at each end. If one end is anchored to a wall or stair stringer, a single freestanding post is enough. For spans of 3 m or more, add an intermediate post every 1.5 m.

Does this post need treating before installation, even if it is Douglas fir?

Douglas fir is supplied unfinished and untreated. For outdoor use, apply an exterior oil or wood stain to every surface before installation, including cut ends. Naturally durable class 3 Douglas fir resists fungi and insects, but an annual surface treatment significantly extends the life of its appearance and limits greying. Fir, pine and beech require a treatment suited to their intended use (indoors only).

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

The straight post (70x70 mm section, 120 cm high) has sharp edges and a clean, contemporary profile. The turned post is shaped on a lathe, giving it a more classic, traditional profile. Both have the same section and height, but look distinctly different. Choose the straight post for a modern interior and the turned post for a traditional-style staircase.
