Wood Tread Options for Your Floating Staircase in Palm Beach, FL

At Palm Beach Floating Stairs , every floating stair we build uses a laser-cut steel structure — fabricated in our shop, delivered with a factory-applied marine-grade finish, and installed without any on-site welding or grinding. This page is about the wood tread choice that goes on top of that structure, and why it matters for Palm Beach's coastal climate: the salt air, the UV intensity through floor-to-ceiling windows, and the year-round humidity that determines which species hold up and which don't.

Palm Beach homes run their HVAC year-round. The indoor humidity in a well-maintained estate usually stays between 50–60% relative humidity. That's actually a stable environment for hardwood — more stable than a climate with harsh winters. The threat here isn't seasonal fluctuation; it's the UV load. South-facing foyers with large windows or transom lights bleach unprotected wood fast. We spec UV-inhibiting finish systems and recommend species with natural UV resistance for stair runs that catch direct sun.

White oak is our most popular interior tread species in Palm Beach. It takes stain evenly, holds its color longer than walnut under UV exposure, and grain patterns are consistent enough across a full stair run that you don't get an awkward mix of tight and open grain between treads. Walnut is beautiful and we use it, but it moves more with humidity and fades faster under direct sun — we're candid about that tradeoff. For semi-exterior stairs, loggia stairs, or treads near pool areas, Ipe is the only hardwood that makes sense. It has a Janka hardness of 3,680 and resists mold, moisture, and insects without any finish required.

The way treads mount to the steel substructure matters as much as species selection. We use hidden clip systems that allow each tread to move slightly across the grain with seasonal humidity changes. Rigidly screwing wood to steel causes cracking within a couple of years as the wood tries to expand and can't. Our clip system gives each tread a 1/16-inch float tolerance — invisible to the eye, but enough to prevent stress fractures at the fastener points.

Hardwood Species and Finish Options for Palm Beach Homes

Finish selection depends on UV exposure, foot traffic, and the look you're after. We offer penetrating oil finishes for a traditional estate feel, hard-wax oils for high-traffic estates, and two-component polyurethane for the most durable surface available. We bring tread samples to the property with different finish options applied — approval happens in your light, not our shop.
