Fire-Rated-Shaft-Door
A Fire-Rated Shaft Door is a specially designed door used in building shafts such as for electrical, plumbing, or elevator shafts to prevent the spread of fire, smoke, and toxic gases through these vertical openings. These doors are constructed from materials like galvanized steel, mild steel, or stainless steel, with fire-resistant core infills such as mineral wool or honeycomb. They are engineered to withstand extreme temperatures for set durations commonly rated at 30, 60, 90, or 120 minutes, effectively containing fire within a compartment and protecting escape routes and adjoining areas.
Key features
- Fire rating: Typically rated from 30 minutes up to 120 minutes, based on strict standards such as IS 3614:2021 and tested by IS 17518-1:2022 or equivalent international standards.
- Material: Commonly made from galvanized iron (GI), mild steel (MS), or stainless steel, with thicknesses of door shutter and frame varying by specification (e.g., 1.2 mm door shutter thickness, 1.6 mm frame thickness).
- Infill Core: Filled with fire-resistant materials like mineral wool or honeycomb to enhance thermal insulation and structural integrity under fire conditions.
- Hardware: Often given powder-coated finishes for corrosion resistance and durability, with color options typically conforming to RAL standards.
- Testing Standards: Compliance with standards such as BS 476, IS 3614, or relevant fire safety certification.
- Size: Common maximum sizes for single-leaf doors are approximately 1200mm width by 2100-2400mm height.
- Additional Options: Doors may feature vision panels with fire-rated glass to maintain visibility while ensuring fire resistance.
Such doors are used widely in commercial, industrial, public buildings, and emergency exit routes to ensure safe evacuation and property protection during fire incidents.
Fire Rated Shaft Door is a safety door designed to withstand fire exposure for a pre-defined time, helping to contain fire and smoke and providing safe egress paths during emergencies.
