Overview

Built for Vertical Shaft Enclosures

Engineered to EN 1634-1 / EN 12101-1 · Manufactured in Jaipur

Heavy-duty hollow metal fire doors engineered for lift shaft enclosures, stairwell entrances and utility risers, where sustained structural integrity and consistent closing performance are critical. The honeycomb core provides a rigid, lightweight infill that maintains door flatness over the service life of the building while delivering fire ratings up to 120 minutes. Single leaf configuration as standard, finished in 6 standard powder-coated colours with custom RAL options for large-volume orders.

Lift shafts & stairwell enclosures

Under Approved Document B and BS 9999, lift shaft and stairwell enclosures in most buildings require fire-resisting doorsets rated EI 60, rising to EI 120 for firefighting shafts and taller buildings. BÖLDT hollow metal shaft doors are tested to EN 1634-1 and classified to EN 13501-2 to satisfy both thresholds from a single product range. Confirm the required period against the current Approved Document B and BS 9999 for the specific building.
