Iron balusters give your staircase a stronger, more finished look than wood spindles, and ours ship ready to install. As an authorized LJ Smith dealer, WoodStairCo stocks nine hollow metal styles in four powder-coated finishes, all 1/2 in square by 44 in. Because we finish our own stair parts in-house, your balusters can be color-matched to our prefinished stair treads, risers, and handrail. Browse the styles below.
An iron baluster is a decorative vertical metal spindle that fills the space between a stair handrail and the treads or floor, forming the railing's infill. Most are hollow mild steel, 1/2 inch square and 44 inches long, cut to length on site and spaced so no gap exceeds four inches.
Did you know: We're an authorized LJ Smith Dealer with access to thousands of stair parts and can finish nearly all stair parts in one of our standard stain colors or even custom stained!

WoodStairCo stocks nine iron baluster styles in three families- plain, twist and basket, and the contempo profiles. The plain bar suits clean modern railings, while single and double twist and single and double basket designs add traditional detail. Single- and double-knuckle styles break up long runs, and the single rectangle and single oval profiles read more contemporary. Every style is available in four powder-coated finishes- oil-rubbed bronze, oil-rubbed copper, low-sheen black, and matte nickel. Mixing two profiles, such as a plain bar with a basket accent, is a common way to add rhythm. Prefer wood? Compare ourwood balusters.
How to install iron balusters
You install iron balusters by cutting each one to length, sliding the top into thestair handrail, then dropping the base into the tread or floor and securing it. Because our balusters are hollow, you can trim them from the bottom with a metal cutting blade, then set them with epoxy and a baluster shoe. The biggest advantage is renovation- you can replace tired wood spindles with iron without removing your handrail ornewel posts, so the rest of the staircase stays in place. For a full walkthrough, see our guide to installing iron balusters.
How many iron balusters do you need
Most staircases use two iron balusters per tread, and wider treads may take three, while level runs, such as balconies, are figured at about three balusters per foot. The rule that governs it all is the four-inch sphere rule- no gap in the railing may allow a four-inch sphere to pass, keeping small children safe. To find your count, divide each tread's run by four

FAQs
1. What is an iron baluster?
An iron baluster is a decorative vertical metal spindle that fills the gap between your stair handrail and the treads. Most iron balusters are hollow mild steel, sized 1/2 inch square by 44 inches, and cut to length on site.
2. How many iron balusters do I need per stair tread?
Most staircases use two iron balusters per tread, and wider treads may take three. To get an exact count, divide each tread's run by four inches, the maximum code gap, and round up.
3. What is the correct spacing for iron balusters?
The building code requires that no gap in the railing let a four-inch sphere pass, so balusters are spaced closer than four inches apart. On stairs, this usually works out to two balusters per tread.
4. Hollow vs solid iron balusters- what is the difference?
Hollow iron balusters are tubular, so they are lighter, easier to cut to length, and lower in cost, while solid balusters are heavier and pricier. Hollow mild steel is strong enough for residential stair railings, which is why we stock it.
5. Can I replace my wood balusters with iron without removing the handrail?
Yes. Using a baluster shoe system, you can swap wood spindles for iron without taking out the handrail or newel posts, since you cut the iron to length and set it into the existing holes.
6. Do I need baluster shoes, and how are iron balusters secured?
Square 1/2-inch balusters use a baluster shoe to cover where the square bar meets a round hole, and a set screw or epoxy holds everything in place. We listrecommended adhesives for a permanent, rattle-free fit.
7. What size and length are your iron balusters?
All of our iron balusters are 1/2-inch square and 44 inches long, made from hollow mild steel. The 44-inch length is trimmed to fit on-site, so one size suits standard stair and balcony installs.
8. What finishes do your iron balusters come in?
Our iron balusters come in four powder-coated finishes- oil-rubbed bronze, oil-rubbed copper, low-sheen black, and matte nickel. All four are available across the styles we stock so that you can mix profiles in one finish.
From plain bars to baskets, our iron balusters give you a durable, code-friendly railing at a fair price, finished to match the rest of your stairs. Shop the styles above, then add coordinatinghandrail fittings to complete the job.
