| Spiral Staircase | Small spaces, lofts, villas | Steel-wood composite steps (CE certified), 0.5m diameter ▲ Advanced: 0.6m diameter | Maximizes vertical space, modern aesthetic, DIY installation (no professional tools) | Narrow treads (25cm) may challenge elderly users, max load 120kg (vs 150kg in straight designs) |
| Straight Staircase | Large homes, commercial buildings | Solid wood steps (20mm thickness, ASTM D543 compliant), 1.2m tread width | Wide treads for easy movement, durable wood (ASTM D543 compliant) | Requires 40% more floor space than spiral designs, less modern aesthetic |
| L-Shaped Staircase | Mid-sized homes, split-level renovations | Steel frame with wooden treads (ISO 3801 verified), 90° turn | Balances space efficiency and aesthetics, modular design (easy customization) | Complex installation (professional required), narrower treads (30cm) than straight |
| Winder Staircase | Tight corners, compact floor plans | Angled treads (15° increments), carbon steel frame (EN 1993-1-1 compliant) | Allows turns without landings, space-efficient for irregular layouts | Uneven tread lengths (safety concerns for children), higher maintenance costs |
| Floating Staircase | Modern homes, luxury spaces | Glass/steel composite steps (304 stainless steel core), cantilevered design | Sleek, open design enhances light flow, ▲ Advanced: 316 stainless for coastal areas | High cost (2x spiral), limited load capacity (100kg), requires structural support |
| Prefabricated Staircase | DIY projects, temporary structures | Pre-assembled steel-wood modules (ISO 9001 certified), 2-hour installation | Fast setup (no carpentry skills), cost-effective (50% cheaper than custom) | Limited customization, lightweight (not suitable for heavy traffic) |
