Systems Overview
GULLY DRAINAGE
ACO Building Drainage gullies represent the
cumulation of many years practical experience and
design know-how in stainless steel fabrication
technologies.
Our state of the art European plants produce
products of consistent outstanding quality but
with economic benefits that can only be realised
through the most advanced manufacturing
methods. All the systems featured here are
manufactured in austenitic stainless steel grades
304 or 316 and are fully pickle passivated in order
to ensure corrosion free product. Their design
includes for smooth bowl shaped structures to
minimise possible siltation, and all include an
integral foul air trap.
The four systems present the designer and installer
with literally hundreds of ‘off the shelf’ product
combinations to meet nearly every conceivable
need or application. However should our range not
meet your requirements we have a considerable
capacity for bespoke design and manufacture:
tundishes, extra inlets, extended bodies or spigots
and non-standard outlet sizes can all be
accommodated, but please allow extra lead time.
The gully systems fall into four main categories:
Micro Floor Gullies; EG150 Eurogully; Fixed Height
Eurogully and Telescopic Eurogully systems.

System Overview
FOUL AIR TRAPS
The foul air trap prevents foul air passing back through the gully from stagnant or dirty water within the
connecting pipework.
The water level is maintained in the gullies by means of weirs formed by the trap unit fitted in the gully body.
These are fully removable to allow rodding of the connecting pipework and easy cleaning of the gully body.
MG Micro Floor Gully System
The foul air trap is an integral part of the grating
and allows full rodding access to the drainage
pipework and eradicates the need for additional
rodding eyes.

ACO VINYL SEAL®
Sealing vinyl sheet flooring
to drainage channels and
gullies
Vinyl sheet is a common flooring finish in many of
the areas where stainless steel drainage channels
and gullies are required. Previously the standard
method of jointing the two was by a mechanical
clamping system.
Cut the ACO Building Drainage Vinyl Seal® rigid
PVC co-extrusion to the required lengths to fit
exactly round all edges of the assembled channel –
do not forget to allow for the mitred ends. Cut and
notch the extrusion to form internal and external
mitres as required.
Although functional, this mechanical clamping
mechanism can be cumbersome to fit and increase
the potential areas for bacterial growth.
In order to overcome the frequently encountered
problems of achieving watertight and bacteria free
seals, ACO have developed the ACO Building
Drainage Vinyl Seal a unique solution that will
enable quick, easy and economical installation. ACO
Building Drainage Vinyl Seal® provides a completely
watertight and bacteria free seal. It can be also easily
removed and re-sealed when the vinyl is replaced or
refurbished without the need to disturb the channel
or supporting detail in any way.
Press the rigid extrusion into the recess at the edge
of the channel ensuring it is pushed fully home.
Peel back the fabric tape protecting the channel
edge in preparation for fitting the flexible PVC seal.
This method of sealing requires no additional tools
or skills than those required for the professional
fitting of vinyl sheet flooring, making the
installation quick, easy and economical.
The seal is significantly more cost effective than the
traditional mechanical type and is designed to fit
ACO Building Drainage stainless steel drainage
channels.
42
Press the flexible PVC seal into position between
the stainless steel channel and rigid PVC extrusion
making sure that the concave section of the seal
faces TOWARDS the channel edge and that the
groove in the flexible seal engages with the notch
on the rigid extrusion (it may help to lubricate the
flexible seal when inserting using a soapy solution).
For an even finish roll the flexible seal in to position
using a small decorators roller.
Installation
ACO VINYL SEAL®
Ensure the assembled ridged and flexible Vinyl
Seal® sits square and horizontal in the channel
Grout any voids at connecting rigid PVC joins at
mitred corners, straight joints or fixings to ensure
a continuous supported floor finish.
Prior to laying the vinyl sheet flooring, peel the
protective film from the rigid extrusion (a knife
may be required to cut the film adjacent to the
flexible seal) and ensure all surfaces are clean
and dry.
detail Install the channel into the ground ensuring
that the flooring screed is flush to the top edge of
the rigid PVC extrusion. Protect the channel and
seal assembly from splashes of concrete/screed.
When preparing the vinyl sheet material and floor
surface, apply a compatible adhesive also to the
top surface of the rigid PVC extrusion for example,
Altrofix 19 two-part water resistant eurethane
adhesive taking care not to apply adhesive to the
flexible seal. This is to ensure the vinyl sheet floor
is reliably anchored over its full area.
Cut/lay the sheet flooring against the flexible seal
edge and prepare the welded joint between the
flexible seal and vinyl sheet flooring as normal by
scoring the sheet/seal joint to approximately half
the depth of the sheet flooring thickness.
Depending upon the installation, additional
suitable fixings may be required to secure the rigid
extrusion to the floor substrate. If this should be
required, separately drill and countersink the rigid
extrusion making sure that all fixings are finished
flush with the top of the extrusion.
Either in-colour or black welding filler rod may be
used to weld the joint. Remove surplus weld
material from the joint using a spatula when the
welded joint has cooled.

CARE AND MAINTENANCE
Although robust, all grades of stainless steel will
stain and discolour due to surface deposits and,
as such, can never be accepted as completely
maintenance free. In order to achieve maximum
corrosion resistance, the surface of the stainless
steel must be kept clean. Provided the grade of
stainless steel and the surface finish are correctly
selected, and cleaning schedules carried out on a
regular basis, excellent performance and long
service life are assured.
Maintenance Programme
Factors Affecting
Maintenance
With care taken during fabrication and installation,
cleaning before handing over to the client should
present no special problems, although more
attention may be required if the installation period
has been prolonged.
Surface contamination and the formation of
deposits must be prevented in order to maintain a
durable and hygienic surface.
Where surface contamination is suspected,
immediate attention to cleaning after site fixing will
encourage a trouble free product.
These deposits may be minute particles of iron or
rust from other sources used on the building of
new premises and not removed until after the
stainless steel drainage products have been
installed. Wire brushes and wire wool must not be
used to remove marks and cement spillages as this
will only serve to introduce iron impurities to the
material surface. Care must also be taken when
storing, erecting or cutting carbon steel near to
stainless steel.
Food and beverage handling, pharmaceutical and
chemical industry applications require extremely
high levels of cleanliness applicable to each
industry.
Industrial and even naturally occurring atmospheric
conditions can produce deposits which can be
equally corrosive, e.g. salt deposits from marine
conditions.
The working environment can offer more
aggressive conditions, for example the high
humidity found in swimming pools increases the
speed of discolouration and therefore requires
maintenance on a more frequent basis.
Modern processes use many cleaners, sterilisers
and bleaches for hygienic purposes. All these
proprietary solutions, when used in accordance
with makers instructions are safe, but if used
incorrectly (e.g.warm or concentrated) can cause
discolouration and corrosion on the surface of any
quality of stainless steel.
44
Strong acid solutions are sometimes used to clean
masonry and tiling of buildings but they should
never be permitted to come into contact with
metals, including stainless steel. If this should
happen the acid solution must be removed
immediately by copious applications of water.
Advice is often sought concerning the frequency
of cleaning stainless steel and the answer is quite
simple: clean the metal when it is dirty in order to
restore its original appearance. This may vary from
once to four times a year for external applications
or it may be once a day for an item in hygienic or
aggressive situations.
Frequency and cost of cleaning is lower with
stainless steel than with many other materials, and
will often outweigh the initial higher cost of this
superior product.

CARE AND MAINTENANCE
Cleaning Methods
Conclusion
Stainless steel is easy to clean. Washing with soap
or a mild detergent and warm water followed by a
clear water rinse is usually quite adequate for many
industrial applications. An enhanced aesthetic
appearance will be achieved if the cleaned surface
is finally wiped dry.
If all the suggestions and actions in the table below
have been attempted, stainless steel has the facility
to be mechanically cleaned by specialists on site.
Please contact ACO Building Drainage for further
assistance.
Precautions
Acids should only be used for on-site cleaning
when all other methods have been proved
unsatisfactory. Rubber gloves should be used and
care taken to see that acid cleaners are not spilt
over adjacent areas.
Special precautions are necessary with oxalic acid.
Solvents should not be used in closed places
without adequate ventilation. Smoking must be
avoided when using solvent. Manufacturer’s
directions should be followed.

Stainless Steel
FAMILIES
Stainless steel is the name given to a wide range of
steels which have the characteristics of greatly
enhanced corrosion resistance over conventional
mild and low alloy steels.
The enhanced corrosion resistance of stainless steel
essentially comes from the addition of at least 11%
chromium, however most stainless steels
commonly used contain around 18% chromium.
Other significant alloying elements include nickel
and for superior corrosion resistant properties,
molybdenum.
For ACO Building Drainage applications, the
principal properties of stainless steel may be
summarised as follows:
Durable and corrosion resistant in highly
aggressive environments.
Hygienic, easily cleaned surfaces.
Aesthetically attractive surface finish.
Good forming and fabrication characteristics.
Excellent strength and resistance to
oxidisation at high temperatures.
All of which make stainless steel an obvious first
choice material for demanding applications.
Stainless Steel Families
Stainless steel is used across a wide spectrum of
engineering applications and this has led to the
development of the vast range of different types of
stainless steels that are now available. There are
four main grades of stainless steel:
Austenitic Stainless Steels
This group of stainless steels is the most widely
used and encompasses the generic 304 and 316
grades of material. These materials are used in the
ACO Building Drainage manufacturing process and
are ideal for applications including food
processing, dairy, brewing, pharmaceutical,
chemical and petrochemical industries.
304 grade stainless steels contain around 18%
chromium and 10% nickel and provides excellent
corrosion resistance. For applications where
superior corrosion resistance properties are
required under extreme conditions particularly
where chlorides are involved, 316 grade stainless
steels are used and contain around 17%
chromium, 12% nickel and 2.2% molybdenum.
Unlike all other grades of stainless steels, austenitic
grades are non-magnetic and as a consequence
magnetic particles are not attracted to the system
surfaces which otherwise would encourage both
contamination and corrosion.
Ferritic Stainless Steels
Ferritic stainless steels have inferior corrosion
resistance properties compared to austenitic 304
and 316 grades and are used in less demanding
applications such as domestic appliance and motor
car trim.This grade of stainless steel is slightly more
brittle when compared to austenitic grades.
Ferritic steels contain between 11.5% and 16.5%
chromium and less than 0.5% nickel. This group of
steels are magnetic and will attract particulates
which can cause contamination problems. Ferritic
steels are not suitable for drainage products.
46
Stainless Steel
FAMILIES AND CORROSION RESISTANCE
Martensitic Stainless Steels
Martensitic steels are magnetic and have the
highest strength of the groups of stainless steels,
however they also have the poorest corrosion
resistance. They can be hardened by heat
treatment and generally find their main application
in cutlery manufacture.
Martensitic steels contain around 12.5% chromium
and contain a relatively high carbon content of
0.3% (austenitic and ferritic steels contain around
0.02% and 0.04% carbon respectively).
Martensitic steels’ poor corrosion resistance make
them unsuitable for drainage applications.
Duplex Stainless Steels
Duplex stainless steels have an effective
austenitic/ferritic structure and are characterised by
good corrosion resistance, high strength and in
particular, good resistance to stress corrosion
cracking.
Duplex steels contain around 22% chromium,
5.5% nickel, 3% molybdenum and 0.02% carbon.
This group of steels are magnetic and will attract
particulates which can cause contamination
problems and therefore are unsuitable for
drainage applications.
Stainless Steel Corrosion
Resistance
The single most important property of stainless
steels and the reason for their existence and
widespread use, is their natural corrosion
resistance. In spite of their name, stainless steels
can both ‘stain’ and corrode if used incorrectly.
The reason for the good corrosion properties is due
to the formation of a very thin, invisible oxide film
that forms on the surface of the material in
oxidising environments such as the atmosphere
and water.
This film is a chromium-rich oxide which protects
the steel from attack in aggressive environments.
As chromium is added to a steel, a rapid reduction
in the corrosion rate is observed because of this
protective film. In order to obtain a compact and
continuous passive film, a chromium content of at
least 11% is required. Passivity increases fairly
rapidly with increasing chromium content up to
about 17% chromium.
The most important alloying element is therefore
chromium, but a number of other elements
including nickel, molybdenum and nitrogen also
contribute to the corrosion resistance properties of
stainless steels. Other alloying elements may also
be added to enhance the corrosion resistance in
particular environments.
Stainless steels must oxidise in order to form the
passive, chromium-rich oxide film. Stainless steels
have a very strong tendency to passivate and only
a small amount of oxidising agents are needed for
passivation - air and water are sufficient to
passivate stainless steels and indeed, this oxide film
is spontaneously regenerated when exposed to
oxygen. An important factor to note is that the
passive film is self-healing, so when the material is
cut or machined or, should chemical or mechanical
damage occur, the passive film will ‘heal’ or repassivate in oxidising environments - unlike a
painted finish on mild steel.
Selection of the correct grade of material for each
application is an important factor in the design
process. It is important to note that even 316
grades of stainless steel are not immune to all kinds
of chemical attack; use with reducing solutions,
such as hydrochloric and oxalic acids particularly
when in concentrated and/or hot form, requires
careful consideration. See material resistance chart
on pages 8 and 9.

FINISHING PROCESSES
Stainless Steel Finishing
Processes
A stainless steel finish should appear clean, smooth
and faultless. This is obvious when the steel is used
for such purposes demanding stringent hygiene or
decorative trim applications, but a fine surface
finish is also crucial in respect to its corrosion
resistant properties.
The corrosion resistance properties of stainless steel
are achieved by the spontaneous formation of a
very thin chromium-rich oxide layer over the
surface of the material. Unfortunately, surface
defects and imperfections introduced during the
manufacturing process may drastically disturb the
self healing process of the passive layer and
subsequently reduce the corrosion resistance of the
material. In the manufacturing process it is the
welding that creates the greatest challenge to
corrosion resistance. All ACO Building Drainage
products are subjected to specialised treatment to
ensure the material retains the maximum resistance
to corrosion.
Pickle Passivation Plant
Untreated Stainless Steel
The blue oxide film has substantially reduced corrosion
resistance.
After welding stainless steel, a bluish high
temperature oxide film can be seen which has
substantially inferior corrosion protection properties
compared to the original passive layer. Immediately
beneath this blue oxide film is a thin layer of
chromium depleted metal which makes the metal
surface susceptible to corrosion. Post weld
treatment is, therefore, very important to restore
the corrosion protection properties and is
effectively achieved by removing the blue high
temperature oxide film and chromium depleted
layer to restore the surface of the material. This
‘cleaning’ is essentially a controlled corrosion
process using chemicals, this will restore not only
its original corrosion resistance performance but
also the high quality aesthetics.
The chemical processing methods used in the
ACO Building Drainage process are summarised as
follows:

FINISHING PROCESSES
Pickle Passivation
Electropolishing
The standard ACO Building Drainage manufacturing
process uses the pickle passivation chemical finishing
process to restore the products to their full optimum
corrosion resistant state without damaging the
surface finish. This is considered the best method for
cleaning welded joints.
Electropolishing is ideal for producing a uniform,
highly reflective lustre with an extremely smooth
finish even on the most complex product contours.
This is a well proven method of polishing and is
achieved by an electro-chemical process which is
essentially the reverse of electroplating.
Pickle passivation is a two-phase process.
Electropolishing.
Pickle Passivation Process.
Electropolishing further enhances surface smoothness and
provides a brighter surface appearance.
Pickle Passivation restores corrosion resistance properties fully.
Pickling removes both the bluish high temperature
oxide film and the chromium depleted layer and is
achieved by placing the components in a pickling
bath containing a mixture of nitric acid and
hydrofluoric acid.
The second phase is passivation and in many ways
is similar to the pickling process. For this process
the components are placed in a bath containing
nitric acid only. This treatment strengthens the
passive layer and also removes any iron impurities
that may have become embedded in the surface
of the stainless steel during the manufacturing
process.
This treatment is important where mechanical
cleaning of the components has taken place with
the use of wire brushes, grinding wheels and files
where iron particles from other materials may
contaminate the stainless steel surface.
The components are immersed in a bath of
electrolyte containing phosphoric acid where the
components become the anode of a direct current
electrical circuit. The process is characterised by the
selective attack on the surface of the components
whereby upstanding roughnesses are preferentially
dissolved and will yield a progressively smoother,
brighter surface.
For pharmaceutical and food processing
industries, bacterial resistance is
considerably improved by the
electropolishing process.
Certain gratings within the ACO Building Drainage
range are electropolished as standard. All stainless
steel products can be electropolished if required to
special order.
