Stertil Stokvis RapidRoll
doors, type RR600 Ultra, are
relied upon by British
Gypsum to support the
company’s mining operations
in East Leake and Barrow
Upon Soar in Leicestershire.

The doors have been
installed over the past four
years to provide access
between different sections
within the mines. Operated
manually by a simple pull
cord on each side, the doors
ensure fast-acting access for
personnel and vehicles.

RapidRoll units are
designed for high-traffic
areas where fast operating
speeds and frequency of use
are key requirements. Other
benefits claimed include a
reduction in energy costs,
draughts and noise. The
RapidRoll 600 Ultra offers
opening and closing speeds
to 3.2 and 0.8m/s respectively
and is available in a range of
standard sizes up to 6 by 6m.

Modular design enables the
door to be custom-configured.

Air pressure within the
mines fluctuates and can be
significantly high. The Class
3 wind resistance classification
of the RR600 ensures no
reduction in performance.
