Stainless Cable
Macalloy cable systems offer a logical
extension of the Macalloy 460 and 520 bar
systems available.
These specially designed systems
incorporate swaged studs and cable
adapters, which allow standard swaged
cables to be connected to our range of
forks.
Stainless steel cable is manufactured
from high tensile, high quality austenitic
stainless steel grade 1.4401 (S316) to give
good corrosion resistance.
Macalloy offer three different types of
stainless steel cables in a range of sizes:
1 x 19 Strand is the most common cable
used. A rigid strand, with a high minimum
break load and low stretch characteristics.
The wires have a smooth bright finish. All
Macalloy cable tendon fittings are designed
to match the breaking load of the 1 x 19
strand cable.
7 x 19 Strand is the most flexible of the
cable types available. It has the lowest
break load of the three cable types but it is
often used in low load applications where
the flexibility is required.
Compact Strand is the most rigid of
cables with very low stretch characteristics
and high tensile strength. This cable has
a high resistance to wilful damage and
vandalism and in sizes 6mm and above
offers a breaking load approx. 25% higher
than the 1x19 wire strand. It has a smooth
and attractive flattened outer layer and
offers improved corrosion resistance.
Stretch in Stainless Cable
Wire cable undergoes two types of stretch
under load – an initial stretch and then a
conventional elastic stretch.
Initial Stretch
The stretch is dependent upon cable
construction and is caused by the
individual wires bedding down into a
loaded position. This is permanent stretch
and can be between 0.10% and 0.75%
of the cable length, depending on the
magnitude and frequency of loading.
This should always be considered when
designing tendons.
Elastic Stretch
Once a cable has bedded down the elastic
stretch will then be proportional to the load
applied. The elastic stretch of a cable can
be calculated by the use of the following
formula: -
d = Load (kN) x Length (mm)
E (k/Nmm2) x Cross Sectional Area (mm2)
Where E =1 x 19 Strand 107 kN/mm2
Compact Strand 133 kN/mm2 7 x 19 Strand 85 kN/mm2
Please note that the above E values have
been established empirically. No cable
will behave completely elastically and the
apparent E value will consequently change
over different stress ranges. Accurate
stiffness values can only be calculated
using a reduced cross sectional area.
Please contact our technical department
for further details if necessary.
Pre Stressed Cable
For applications where stretch is credited
to the construction it can be eliminated
by pre stressing the cable. In general pre
stressed cables are only necessary on
large diameters. The tensioning devices
available with small diameter stainless
cables are usually sufficient to remove any
stretch. If pre stressed cable is required
consult Macalloy Technical Department.
Standard Components
There are a range of different standard
components available, each to suit different
architectural preferences and different
budgets. Irrespective of the system chosen,
all components are made from austenitic or
duplex stainless steels. Swaged fittings are
factory swaged to the cable.
All components for our cable systems are
designed to match the minimum break
load of the 1x19 strand cable. If fittings are
required to match the minimum break load
of compact strand, please seek advice from
Macalloy Technical Department with regard
to component sizes.

Macalloy Cable Systems
The standard cable systems that Macalloy
offer are:
Macalloy SC460 Architectural Cable
System – a system that offers the S460
bar forks in a cable system. Adjustment is
at both ends.
Macalloy SC460 Architectural Cable
System with Swaged Tensioner – this
system provides a fixed S460 fork at one
end and adjustment through the tensioner
at the other end. If preferred, the swaged
fork can be offered at both ends, with an
in-line tensioner in the middle of the cable.
Macalloy GL Architectural Cable System
– the GL refers to the original name of
the cable system, Guy Linking. Similar to
the Macalloy SC460 cable system, this
provides adjustment at both ends. The
forks are machined from round bar.
Macalloy GL Standard Cable System
with Swaged Tensioner – this system
provides a more basic swaged fork at one
end and adjustment through the tensioner
at the other end. If preferred, the swaged
fork can be offered at both ends, with an
in-line tensioner in the middle of the cable.
Connection Plates
All forks may be connected to either
carbon steel or stainless steel connection
plates with an equivalent strength to BS
EN 10025 grade S355 or duplex stainless
steel to BS EN 10088.
Where carbon steel plates are used,
isolation sleeves and washers may be
required to prevent bi-metallic corrosion.
Finish
All components are finished to a minimum
Grit 220. (N3) polished finish. Other
finishes are available on request. Please
contact a member of the sales team.

Stainless steel cable will begin to distort at around 50% of its breaking load. For this reason it is recommended to apply a factor of safety of 2 and not to load the cables to more than 50% of their breaking loads. *1 x 37 or 1 x 61 may also be offered.
