iron railing balusters

They are commonly made from galvanized steel, wrought iron, steel, and carbon steel.

Common weather-resistant finishes include powder-coating and galvanization; some listings also note AAMA‑2604‑compliant coatings. Descriptions commonly state these finishes provide corrosion resistance and protection against sun and rain for outdoor use.

Many balusters come pre-drilled to speed installation and support vertical or wall-mounted configurations. Listings often include screws or basic hardware; some kits note that additional tools (drill bits, etc.) are required.

Product details commonly recommend keeping spacing at or below 4 inches, with some listings explicitly stating a maximum spacing of 4 inches.

Common lengths shown in the listings include 44 inches, about 32.25 inches, and a standard decking height around 36.02 inches.

Common shapes and profiles include hollow twisted/spiral shafts, wave or curved spindles, square profiles, and hollow rectangular spindle styles.

Descriptions indicate hollow steel tubing is generally easy to trim for length adjustments. Some kits include installation accessories to assist trimming; in other cases, finishing items such as shoes may be sold separately.
