Metal stair spindles are a great alternative to timber and glass stair parts.

Metal Stair Spindles have been really popular in 2022, this article takes a look at why. A staircase occupies the most prominent position in a house and perceived by many as the main focal point of a home. With this in mind, selecting the right stair spindles - and other balustrade components - are of great importance.

If you are searching for something affordable which looks great, is safe for all the family and requires very little in terms of maintenance, metal spindles are an excellent option. Gone are the days where you would see metal spindles purely in an industrial setting; they are gaining much popularity in stair renovation projects also. Why are they so popular?

1 - Metal Stair Spindles Look Great in a Variety of Unique Designs

If you want the focal point in your home packed full of character and quirkiness, metal stairway spindles are a perfect take on a rustic and traditional feature that will fit nicely in both a contemporary and traditional setting. They can take on a simple design such as square or rounded, or a more ornately curving design such as Elements Black Iron. They can be mixed with glass or even timber to create that real wow factor. Whether you want soft and elegant or square and hard-edged, metal should always be your material of choice for spindles stairs.

2 - They Are Tough and Will Last for Years

They are built to last. Unlike timber stair parts, they are not vulnerable to changes in the environment and will not bend nor warp like other staircase spindle. Metal is tough, durable, and will last for years which makes it a great long-term investment and cost-effective option if you are in the stair renovation market.

3 - Easy To Install and Versatile

In particular, the Black Iron Balustrade system has been designed to give a modern look to your staircase without the need of fussy connecting brackets. The iron spindles slot into the pre-grooved handrail and base rail and are then secured using a bed of silicon that sits between the solid oak fillet strips supplied. This system can be used with any newel post in any timber - new or existing - allowing you to mix oak rails with white painted posts for example.

Leaving your existing newel posts in place makes the job quick and easy, refreshing your staircase in a matter of hours. With a reduced installation time means reduced costs, sounds good right?

If you are planning to use an existing handrail and base rail, please take a quick look at the below video for some helpful tips and guidance:

4 - Low Maintenance

Metal will always win over other materials when it comes to maintenance and upkeep. If painted correctly, your spindles will not rust or fade.

When it comes to buying and installing metal spindles or any other stair balustrade component, it is important to consider building regulations. You should always ensure any structural additions to your property meets all the current regulation for safety and to avoid having to make costly changes later on in your project. For further guidance and more in-depth regulatory help, please see Approved Document K (available from or get in contact with a local building inspector. You can find below some common regulation points (for domestic staircases only):

  • Staircases should have a maximum rise of 220mm, minimum going of 220mm, and a maximum pitch of 42°. These measurements are for domestic staircases only. If the staircase in question comes under the category utility or general access, these will be different.
  • Staircase steps should all be level.
  • If your staircase is less than one metre wide, you will need at least one handrail. Any flights over one metre will need a handrail installed on both sides.
  • Handrails on stairs and landings should have a minimum height of 900mm
  • Stair Spindles of any kind should be no further than 100mm apart
  • You are required to have a minimum of 2,000mm of clear headroom above the pitch line.
