Stackable Stairs offer an ideal solution for modern architectural projects that demand structural integrity and clean aesthetics. Therefore, our engineered systems are perfectly suited for luxury residential homes, commercial studios, and lofts. Built with double-laminated steel plates, each system reliably supports thick hardwood or stone treads. Consequently, it delivers a striking floating visual profile.

Configurations for Stackable Stairs

Every architectural layout features distinct spatial requirements. Consequently, we fabricate custom stackable stairs in two primary layouts:

  • Straight Flight: In particular, the straight design creates a clean linear accent for living rooms, entryways, and finished basements. Exposed steel plates pair elegantly with timber treads to warm up modern spaces.
  • U-Shape & L-Shape: Incorporating intermediate landings, these configurations provide safe foot traffic. In addition, they anchor double-height foyers, boutique hotels, and luxury commercial lobbies.

Modular Stackable Stairs Engineering

Furthermore, our precision laser-cut stringers provide remarkable adaptability for custom projects. Fabricators can integrate these modular units into versatile stair towers or mezzanine access systems. In addition, connection points are pre-drilled for rapid bolted assembly. As a result, this design cuts on-site welding time and reduces project labor costs.

Custom Materials & High-Grade Finishes

Exceptional durability begins with industrial-grade raw materials. Therefore, we construct every stackable stairs stringer using Q235 and Q355 structural carbon steel plates. Next, we apply multi-stage powder coating to resist scratches, wear, and indoor moisture.
Moreover, clients can choose 100mm to 120mm solid hardwoods like white oak, American walnut, and teak. In addition, you can pair these steps with 12mm tempered safety glass balustrades for open sightlines.

  • FAQ
What are stack stairs and stacked stairs?

Stack stairs (also called stacked stairs or stacked staircase ) use stacked steel plate stringers (10mm+10mm) supporting box treads – a laminated construction that offers exceptional strength and a unique aesthetic.

We offer straight and U-shaped stack stairs. Straight is most common; U-shaped suits grand spaces with landings.

The stacked steel plate construction provides exceptional durability and load-bearing capacity – ideal for basement stairs that see heavy use.
