Powdercoated aluminium square posts — a beachside-friendly affordable option for modern wire balustrade systems. Made from 6061 T6 aluminium with a Dulux Protexture powdercoat, these posts suit residential decks, alfresco areas, and staircases in standard and coastal environments*. Standard specification for compliance with NCC guidelines.

Beachside Environments (and other corrosive areas):

  • Combine it with slimline Stainless Wire Balustrading for a popular look

Non-Coastal Areas

  • Combine it with Black Wire Balustrading for a hidden finish to the balustrade.

Matte black is the standard colour. Custom powdercoat colours are available — request a quote with your preferred finish. All posts are designed for flat handrail.

Are these posts suitable for coastal locations?

Yes (Mostly) — powdercoated 6061 T6 aluminium that has been powdercoated by a Dulux Accredited powdercoater using the Dulux Protexture range is suitable for most residential beachside and exposed outdoor environments*. It's the recommended choice where powdercoated stainless is not an option, including homes near the ocean or in other corrosive locations.

*See the Dulux Protexture website for its performance and project suitability in different environmental conditions. The coating is covered under the Dulux Alumi Shield Warranty for Protexture. See the Warranty for where the coating is and isn't covered including residential vs commercial applications and distances required from corrosive sources.

Are stair posts available in aluminium?

Yes*. Angled stair posts (end and intermediate) are listed on this page and available on request. Request a quote with your run angle and length to confirm pricing and lead time.

Limited to certain stair angles:

As a unique feature of the top plate design of the aluminium posts they are limited for use with 33-38°. The top plate can be modified on request for 27-33°. Degrees outside this require the client to manufacture their own top plate - however the posts can be drilled and cut to suit these different angles with in-house manufacturing.

These posts are not suitable for ramps, stringers or side-mounting as the base plate is pre-welded and cannot be modified.

Manufacturing of the stair posts is slightly different from the stainless posts.

What we require for stairs:

  • Going and Rise of the stairs
  • Number of stairs
  • Any differences between the stairs

The design team will draw a diagram based on your provided information for your approval before commencing production.

What's the difference between aluminium and stainless posts?

There are a lot of considerations when choosing posts including specifications for compliance, customisabillity, cost and compatability.

You can view more of the differences between our wire balustrading post ranges in our guide here.

If you want a broader overview of the differences in balustrading posts, including the differences between aluminium and stainless, go here.

What wire balustrade fittings (kits) do they suit?

Hydraulic Swaged Kits.

The Aluminium Posts can come with Pre-Installed M6 RHT or LHT RivNuts in either Black or Stainless (these are installed after powdercoating), or without thread but with a 9mm hole.

Design your floor plan layout first to determine what configuration of posts and kits you need.

Stainless Kits to use with RivNuts (coastal):

Kit #60 (not suitable for stairs) - Requires connection to a LHT post on one end and a RHT post on the other (LHT/RHT)

Kit #60s (suitable for Stairs) - LHT/RHT

Kit #70 (not suitable for Stairs) - RHT/RHT

Kit #7 (suitable for Stairs) - RHT/RHT

Kit #97 (suitable for Stairs) - RHT/RHT

Stainless Kits to use without RivNuts (coastal):

Kit #100 (limited suitability for stairs)

Kit #101 (limited suitability for stairs)

Kit #102 (limited suitability for stairs)

 

Black Kits to use with RivNuts (non-coastal):

Kit #BP60 (not suitable for stairs) - Requires connection to a LHT post on one end and a RHT post on the other (LHT/RHT)

Kit #BP60s (suitable for Stairs) - LHT/RHT

Kit #BP7 (suitable for Stairs) - RHT/RHT

 

Black Kits to use without RivNuts (non-coastal):

Kit #BP100 (limited suitability for stairs)

 

You can view more of the differences in our guide here.

What handrail type do these posts suit?

All posts in this range suit flat timber with a base width of 65mm or aluminium handrail.

We aren't recommending alternative metal handrails due to the risk of dissimilar metal corrosion.

For round handrail options, see our Round Wire Balustrade Posts.
