Cova Security Gates installed on
London Building of theYear 2016!
Announced recently in many UK architect
publications was ‘The City of London Building of
the Year 2016‘ which consists of two buildings
located at ‘New Ludgate’ in the heart of St Paul’s
London, and adjacent to England’s most famous
court, the Old Bailey.
Cova Security Gates who have this year
achieved certification of ISO 9001: 2015
Quality Management Standard were delighted
to receive this latest announcement as the
building was commissioned with the installation
of their popular CSG 10601 bi-fold speed gate
at the rear of the building, for which it offers
security for its delivery goods area – which is in
operation 24 hours a day, 365 days a year.
Designed in the UK, this first generation bi-fold
automated speed gate is the perfect solution
where height and span of opening are critical
factors. The client specifically required the gates
to blend in with the aesthetics of the building.
Standing at 4.75m high and over 10.5m wide
– that’s a lot of gate and one of their largest
Speed Gates built to date!
The CSG10601 Bi-Folding Speed Gate consists
of two posts, onto each post a bi-folding leaf is
attached by hinges. The posts are connected
by an overhead operator box which is cleated
to and supported by an adjacent external
structure, generally integral to a building.
The bi-folding leaf utilises an overhead guide
track within the underside of the operator box
assembly, there is no requirement for ground
guides or track.
The post hung section of the bi-folding
leaf is driven by 3-phase/50Hz drive motor,
output speed 33rpm driving through 18:95
ratio spur drive gear, locking in both the open
and closed positions, leaf movement can be
accommodated to open either inwards or
outwards. Gate leaf sections are fully welded
assemblies, constructed of RHS steel section,
vertical infill bars at 100mm spacing as standard
although additional / alternative materials can
be accommodated to suit.
Typically a gate will consist of a pair of bi
folding leaves, capable of spans up to 15000mm
W x 5000m H clear aperture, single bi-folding
leaf gates can be produced if required. Gate
leaves can be operated by a single drive unit
simultaneously, or individual drives for larger
spans or where individual leaf control is
required. Drives are located within the operator
box and are controlled by a Programmable
Logic Controller (PLC) located within the
associated control cabinet. All gate systems
come complete with a safety photocell system
between the gate posts.
What makes these London buildings
of the year unique is that they have over
35,210 square meters of retail, restaurant and
commercial office space over 9 floors and a
roof terrace with stunning views over London,
with building designs that make them stand
out from most others in the area.
You can view the actual gate in a time lapse
video in their factory being built and tested
prior to being installed. Cova factory test
EVERY gate from their UK manufacturing site
in Crawley, near Gatwick prior to being sent
out for installation. 
