Stair towers — fabricated steel stairways for industrial plant access
Stair towers are the fabricated steel stair-and-landing assemblies that connect operating levels, pipe rack tiers, and equipment platforms in process plants. They must meet the project’s structural design, tread/riser layout, handrail requirements, and escape-route width defined by the EPC specification — not a catalogue off-the-shelf kit. Sun Corporation fabricates stair tower steel at our Jeedimetla workshop: stringers, landings, handrails, and connection plates to IS 800:2007 with full weld and material records.
Fabrication and erection
- Shop-fabricated stair flights and landings with piece marks
- Bolted connections to platform and rack steel on site
- Grating or chequered plate treads when in structural scope
- Galvanised or painted finish per project corrosion class
- Erection tolerance checks to IS 800 Annex G
EPC documentation
Stair towers are frequently on the PMC witness list for weld quality and dimensional check before grating installation. We include stair tower components in the master ITP with hold points as specified. Prequalification documentation: manufacturer credentials.
Typically supplied with industrial platforms and pipe rack packages in the same contract.
