The Story
Square black metal staircase spindles measuring 13mm x 1118mm are a straightforward, modern choice for interior balustrade projects. Made from hollow mild steel with a matt black powder coat finish, these spindles are designed to fit directly into 13mm groove handrail and base rail systems.
Specifications
| Property | Detail |
|---|---|
| Material | Mild steel (hollow section) |
| Finish | Matt black powder coat |
| Nominal Size | 13mm x 13mm |
| Length | 1118mm |
| Profile | Square |
What it's used for
- Infill spindles for straight and landing staircase balustrades in new-build and renovation projects
- Replacement spindles where existing square black metalwork has been damaged or removed
- Contemporary staircase redesigns pairing metal spindles with timber handrails and base rails
- Commercial and residential interiors where a clean, uniform metal balustrade is specified
Fitting and handling
These spindles slot into a 13mm routed groove in both the handrail above and the base rail below, so check your rail profile before ordering to confirm compatibility. No acclimatisation period is needed for steel spindles, but store them flat and dry before installation to avoid surface scratching or moisture causing any edge rust at cut ends. If you trim spindles to length on site, apply a small amount of black touch-up paint to any exposed cut edges to maintain the powder coat appearance.
FAQ
What handrail do I need to use with a 13mm square metal spindle?
You need a handrail and base rail machined with a 13mm groove to accept these spindles. Nottage Timber Merchants stocks matching base rail in the staircase section - check the baserail collection for compatible profiles.
How many spindles do I need per step?
UK building regulations require that a 100mm sphere cannot pass through any gap in a balustrade. For most domestic staircases this typically means two spindles per tread, but always measure your specific tread width and spacing to confirm the correct quantity before ordering.
Can these spindles be used outdoors?
These spindles are intended for interior use. The powder coat finish offers reasonable surface protection, but untreated cut ends and prolonged exterior exposure can lead to rust. For outdoor balustrade projects a galvanised or stainless option would be more suitable.
