Description

Minimalist Modern White Steel Helical Spiral Staircase

Elevate high-end architectural interiors with our minimalist modern white steel helical spiral staircase. Engineered with heavy-gauge structural carbon steel in an open-center helical geometry, this staircase features a seamless curved outer steel apron balustrade, an integrated inner steel handrail wall, and precision-fabricated steel treads, delivering a pure, fluid, and sculptural architectural statement.

INCLUDED Features:

  • Seamless Solid Steel Outer Apron Balustrade: Smoothly curved full-height steel outer plate acting as both structural load-bearing stringer and integrated safety guardrail.
  • Integrated Inner Steel Handrail Wall: Smoothly contoured inner steel guardrail wall following the natural spiral arc for safe, balanced ascending.
  • Precision Fabricated Steel Treads: Heavy-gauge steel tread supports engineered with durable white finish coating for high load-bearing capacity and structural rigidity.
  • Concealed Heavy-Duty Steel Base Hardware: Anchor plates and high-tensile mounting hardware engineered for seamless floor-to-ceiling structural integration.

Signature Features:

  • Full Structural Steel Integrity: Built from high-strength carbon steel with double-curved under-stringers for superior torsional stiffness, zero-vibration stability, and long-term durability.
  • Center-Post-Free Helical Engineering: Open-center helical geometry eliminating the traditional central support column, maximizing light penetration and spatial openness.
  • Premium Matte White Anti-Corrosion Coating: Multi-stage rust-inhibiting treatment finished with a durable matte white powder coating resistant to scratches, yellowing, and wear.
  • Precision Factory Welding & Seamless Finishing: Hand-finished welds and continuous smooth joints providing an uninterrupted, ribbon-like metallic aesthetic.
  • Pre-Engineered Precision Assembly: Manufactured in factory molds with strict tolerances to ensure quick, reliable site erection.
  • Fully Customizable Metal Specifications: Overall height, diameter, rotation direction, steel plate thickness, and custom finish shades tailored to exact architectural drawings.

Close-up detail: Smooth seamless matte white steel apron sweeping gracefully along the precision-fabricated steel tread profile.

EugeneFrom Spain
I really prefer this kind of classic, traditional style for doors and windows; I updated all 13 doors and 16 windows in my villa to a classic black-and-white theme. The result is truly stunning.

I ordered the stair railings and large iron gate from Like Metal. Well, it saved me a lot of money on renovations. But the quality is the same as locally made ones; Chinese manufacturing is truly impressive!
