Guardrails & Steel Balustrades
Engineered guardrails and balustrades for stairs, decks and ledges.
Engineering Excellence in Guardrails & Steel Balustrades
Thobal designs, fabricates, and installs steel guardrails and balustrades for staircases, balconies, mezzanines, rooftops, and edge-of-slab locations. Our systems are engineered to resist the specified infill and concentrated loads with minimal deflection, and finished in galvanised, powder-coated, or stainless steel to match the architectural intent. Glass and mesh infill combinations are available for modern, light-filled spaces.
Why Clients Choose Thobal
- Engineered to SBC and international loading standards
- Steel, stainless steel, glass, and mesh infill options
- Minimal deflection under concentrated and infill loads
- Corrosion protection for coastal and industrial environments
- Fully documented structural calculations and testing
- Curved, angled, and feature balustrade fabrication
Scope of Work & Deliverables
Dedicated engineering supervision and full-scope execution across every stage of guardrails & steel balustrades.
Balustrades are engineered to SBC 301, EN 1991-1-1, and IBC loading requirements, with structural calculations for consultant approval and certified fabrication in galvanised, powder-coated RAL, or stainless steel with glass or mesh infills.
Base plates and core-drilled fixings are engineered for each substrate, with marine-grade stainless or duplex-coated systems for coastal environments — verified by load testing and deflection checks for staircases, balconies, mezzanines, and rooftops.
Execution follows an engineered sequence — structural design approval, certified fabrication, surface finishing, and installation with engineered base plates, core-drilled fixings, or face fixings verified for each substrate. Quality is assured through weld inspection, deflection checks, and load testing, with marine-grade systems specified for coastal exposure. Safety governs working at height and edge protection during installation, and deliverables include structural calculations, load test records, and as-built drawings.
