CEMEX offer precast concrete stairs
and landings to suit most
combinations of floor layouts
Our units include standard
stair flights and bespoke
incorporating curves and
bull-nosed if required.
SpeedInstallation is rapid providing instant
access between floor levels*.
Stairs and Landings will provide a
ONE-hour a fire resistance.
DurabilityPrecast concrete is unaffected by
climatic conditions and is suitable for
external and internal use.
FinishesBalustrade fixings can be provided in
the form of pockets, however we would
generally recommend that fixing for the
balustrade be drilled on site.
Stairs and Landings are manufactured in
moulds which produce Type A finishes
as described in clause 18.104.22.168 of
BS8110 part 1 1997.
We do recommend
that finishes are applied to the units after
The dimensional requirements for all
staircases are set out in the Building
Regulations Approved Document K.
The requirements for the three categories
of stair considered in the Building
Regulations Approved Document K and
that for disabled people in Approved
Document M are as follows:
 The maximum pitch for a private stair is 42°. For dwellings, for external tapered steps and stairs that are part of the
building the going of each step should be a minimum of 280mm.
 For school buildings, the preferred going is 280mm and rise is 150mm
*Instant access is possiblefollowing installation of suitable edge protection.
**The normal relationship between the dimensions of the rise and going is: twice the rise plus the going (2R+G) equals
between 550mm and 700mm.
For existing buildings the dimensional requirements in the table should be followed, unless due to dimensional
constraints it is not possible. Any alternative proposal should be agreed with the relevant building control body and
included in an access strategy (refer to Approved Document M)
