Design & Installation Process
From Concept to Completion: Our Spiral Staircase Process
Space Assessment & Design Development
We visit your site to assess the available space, measure constraints, and discuss your requirements. Our team determines optimal diameter, rise calculations, and configuration (central column or self-supporting) based on your space and usage needs. Initial design concepts are developed with 3D visualisation for complex projects.
Engineering & Approval Coordination
Detailed engineering calculations ensure structural adequacy and building regulation compliance. We prepare technical drawings, foundation requirements, and coordinate any necessary building approvals. For multi-level installations, we ensure proper emergency egress compliance.
Precision Curved Fabrication
Your spiral staircase is precision-manufactured in our Cape Town workshop using specialised curved steel fabrication techniques. Each component is carefully crafted to ensure smooth radius curves and perfect helical geometry. Quality control throughout fabrication ensures every weld and connection meets our exacting standards.
Foundation Preparation & Installation
Installation begins with foundation preparation and anchor point establishment. For central column designs, the primary support is installed and perfectly aligned. Our installation teams use laser alignment to ensure precise positioning and smooth operation throughout the spiral.
Component Assembly & Final Commissioning
The staircase components are assembled in sequence, with continuous handrails fitted to follow the spiral geometry. Final adjustments ensure smooth operation and perfect alignment. We complete with comprehensive testing and provide detailed maintenance guidance for long-term performance.

Frequently Asked Questions
The minimum practical diameter is 1.2m for residential use, though 1.5m provides more comfortable access. Commercial applications typically require larger diameters.
Spiral staircases work well for secondary access but may not be suitable as primary routes in commercial buildings due to building regulation requirements.
Yes, with appropriate materials and finishes. Galvanised or stainless steel and glassnstruction provides excellent weather resistance for external applications.
Tread calculation depends on floor-to-floor height and desired rise per step, typically 180-220mm. We provide detailed calculations during design phase.
Yes, continuous handrails are standard, and we can incorporate additional features to improve accessibility where building regulations require.
