Quality
Stainless steel reinforcements
supplied by Penistone Reinforcements is from the
Itialian Mill Cogne Acciai Specialai SRL. which
holds certificates by UK CARES for concrete reinforcement
products affirming our continued commitment to
quality. Penistone Reinforcements
Ltd are approved by CARES for the supply of Cut and
Bent reinforcing bar.
Stock
Penistone
Reinforcements Ltd not ony hold a full stock of
stainless reinforcing bar, in grades 1.4301 and
1.4436 but also offer a comprehensive cut and bend
service. This enables rebar to be supplied at mill
prices and be delivered direct to your site.
Service is assured
with access to over 2000 tonnes of stock in the
UK as well as the production facilities of the
Rolling Mill in Italy.
Why stainless steel?
Stainless steel is
by its very nature resistant to corrosion attack
this level of resistance is dependent on the environment
and the constituents within the steel.
A particular problem
with large structures is de-icing salt caused corrosion
on the carbon steel reinforcing bars, as they corrode
the products of corrosion are approximately 12
times the volume of the material lost. This results
in extreme pressures within the structure which
create cracking and spalling of the concrete, further
exasperating the problem.
Stainless steel benefits
• Resistant
to road salts and general corrosion particularly
for road structures.
• Low temperature
ductility, material of choice in Liquid Natural
Gas storage structures.
• Maintains strength
at elevated temperatures which can be beneficial
in many industrial applications.
• High ductility, especially
suitable where seismic design must be considered.
• Low Magnetic Permeability
especially useful in miliary, Micro wave towers,
Power Stations and Hospitals, where magnetic
interference will be a problem.
Grades
Material is stocked
in all the standard grades of stainless steel used
for Civil Engineering contracts. Grades identified
by * are supplied by special mill order.
Strength
Reinforcing bar is
supplied in the standard 500 N/mm2 strength, the
two other grades 200 and 650 are supplied on request.
Bar is stocked with dual certification to accommodate
all these specifiations in the popular sizes.
Highways and structures
Recent moves towards
life cycle costing have encouraged engineers to
provide a structure which may be slightly more
expensive at the outset, but over the design life
a structures final cost will be significantly reduced.
The typical marginal
cost for using stainless steel reinforcing bars
on a bridge designed in accordance with the recommendations
of the highways agency document BA 84/02 is only
3%. This presents exceptional "Value Engineering"
when compared to the cost of a road closure, the
disruption of the public because of bridge repair
or an injury due to falling masonary.
