Industrial Steel Beam Floating Stairs in Houston, TX

At Houston Floating Stairs , steel beam stair work starts with the same question every time: what loads is this stringer actually carrying? Residential stairs see different loading patterns than commercial ones. A mono-beam system under a 12-tread residential stair has very different beam sizing requirements than the same count in an office lobby. We run the load calculations before any steel is ordered — not after.

We use ASTM A992 structural steel throughout. It's the same grade used in building columns and beams — not the mild A36 steel some fabricators substitute to save cost. A992 has tighter chemistry controls, which means more consistent strength properties across the full length of the beam. For a cantilevered system where the beam carries every load transferred from each tread, that consistency matters.

Fabrication happens in-house, cut and welded to your field measurements. We don't order pre-made stringer assemblies and adapt them on-site. If your floor-to-floor height is 118.5 inches with a 7.75-inch rise per tread, that's what gets built. Catalog dimensions are for catalog stairs.

Powder coating is the right finish for Houston's climate. Raw steel and even epoxy primer struggle with the combination of high humidity and UV intensity Houston delivers most of the year. Powder coat forms a thermoset polymer barrier that resists moisture penetration, UV degradation, and the temperature swings between Houston summers and air-conditioned interiors. We apply it after all welding and grinding is complete — no post-install touch-up spraying on your stair.

Weld quality on a structural stair isn't optional. Every connection point gets a full-penetration weld inspected before the piece leaves our shop. We don't use tack welds or partial fusion on load-bearing connections. If a weld doesn't pass visual inspection and our in-house check, it gets ground out and redone — not painted over.
