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.
