Industrial and commercial stair assemblies require rigorous structural design to handle heavy dynamic loads while complying with regional safety standards.
Technical Specifications & Fabrication Standards
- Structural Detailing & Configurations:
- Industrial Stairwells: Multi-tier, self-supporting structural steel frameworks spanning multiple floor levels, featuring grating or chequered plate treads and integrated landing platforms.
- Spiral Tank & Utility Stairs: Radiused outer stringers with radial step layouts designed for circular storage tanks, compact plant access, and space-constrained vertical runs.
- Fire Escapes & External Access: High-capacity exterior egress structures built with weather-resistant drainage treads, toe guards, and anti-slip walking surfaces.
- Material & Structural Integrity:
- Primary Steel (MS): Fabricated using MS, IS 2022 / ASTM A36 structural steel channels, ISMC sections, hollow structural sections (HSS), and heavy stringer plates.
- Treads & Landings: Available in serrated steel grating for maximum slip resistance and light transmission, or heavy-gauge chequered plates for solid flooring needs.
- Handrails & Safety Guards: Top rails, mid-rails, and kick plates fabricated from structural pipes or tubes, fully welded to withstand lateral safety loads.
- Coating Systems & Environmental Protection:
- Shop Primer: Red Oxide or Zinc Phosphate primer for indoor, non-corrosive installations or prior to field finishing.
- Epoxy & Polyurethane (PU): High-build epoxy primers and UV-resistant PU topcoats for chemical plants and manufacturing bays.
- Hot-Dip Galvanizing (HDG): Thermal zinc immersion (per ISO 1461 / ASTM A123) option for total corrosion immunity on exterior fire escapes and coastal installations.
