ALUMINUM
DOME
ROOF

8. Aluminum alloy is one of the world’s most commonly used metals.
Lightness - Strength - Excellent Corrosion Resistance
The ATECO aluminum dome roof is a system of:-
• triangular lightweight extruded profiles
• connected through node points
• transmitting all the roof loads laterally to the
integral tension ring
• then through sliding or fixed supports to the
tank shell and the tank foundation.
The framework is covered with a
1.2 mm thick aluminum sheeting
ALUMINUM DOME ROOF

9. All bolted structure and no welding is required at
site for its assembly and erection
Complies with the requirements of API 650 App.G.
The standard ATECO aluminum dome roof is fitted with
Sliding Supports and an Integral Tension Ring. This
reduces the forces being transmitted to the tank shell
and generally means that there is no significant
modification required to the tank.
Totally supported on the tank shell without any need for internal supports .
Aluminum dome roof do not require painting – EVER
Maintenance free for the entire lifetime of the tank.

10. Ateco offer the following features
in our standard design:
• Integral Tension Ring
• Sliding Supports
• Free Vent
Any equipment that you have on a conventional steel dome or cone roof tank
can be fitted on the ATECO aluminium dome roof and without any
significant modification to the equipment or the roof.
The ATECO dome roof ratio
(dome height : tank diameter) is about1:6.
ATECO aluminum dome roof can be designed to
support a suspended aluminum internal floating roof.

13. ATECO can supply all the necessary
assembly and erection equipment
Assembly inside or outside the tank - lifted using
either a system of pulley blocks or a crane
If using the “jacking method” to erect the
tank, the Dome Roof is fitted on the top course
and jacked up with the shell Dome assembly on top of a floating roof
Erection of the ATECO Aluminum Dome Roof

14. • ATECO aluminium dome roof is a self-supporting
structure
• ATECO aluminium dome roof lightweight
construction means that when fitting on an existing
external floating roof tank it is not normally
necessary to reinforce the tank shell
• ATECO aluminium dome roof is fitted with an
Integral Tension Ring to avoid any additional
stiffening requirement of the tank shell
• ATECO aluminium dome roof does not require
painting, EVER - in this respect it can be
considered as maintenance free for the entire
lifetime of the tank
Main advantages of the ATECO Aluminum Dome Roof

15. • Bolted construction makes site assembly
quick and easy
• completely prefabricated panels
incorporating factory applied surface
protection
ATECO supply an aluminum and galvanızed steel formed flat panel roof for bolted tanks in
accordance with AWWA and API 12B
• Pivot hinged connection to the tank
shell
• light weight
• does not require internal supports
• desıgned for a combıned Dead Load
and Snow Load of 85kgs per sq. meter.
Dome and Flat Roofs for Bolted Panel Tanks
For smaller diameter tanks
they are generally more
competitive than a steel
welded tank

The Astrodome in Houston is
200 meters diameter.
Geodesic – means the shortest line between two points
on a curved surface.
Mr Buckminister Fuller from USA developed the
principal of the geodesic dome in the 1940’s
primarily for social housing .
The aluminum dome roof used on tanks is not strictly
geodesic - the main profile beams are connected
at node points on the surface of a sphere.

ROOF

18. ATECO offer as standard a simple double
polyethylene foam seal on all internal floating roofs
• ease of assembly and installation - all component
parts pass through a standard tank shell manhole
• no welding at site - complete installation can
normally be carried out in a matter of weeks
• can accommodate both primary mechanical shoe
seal and a secondary seal
Internal Floating Roofs are installed in Fixed Roof Tanks to control the
vapour emissions from volatile hydrocarbon liquids.
The pontoon type has the most cost effect features:-

19. ATECO offer pontoon and full contact types, that meet and in most cases
exceed the requirements of API 650 Appendix H.
Although there is a fundamental difference in the design of each type of roof, many of their
features and accessories are the same.
Selection is primarily based upon the preference of the owner.

20. The Ateco Robust Pontoon Aluminum
Internal Floating Roof has 254 mm (10
ins) dia. X 2.5 mm thick extruded
aluminum alloy pontoons - 0.5 mm
thick aluminum sheet. Designed to
withstand loads up to 500 lbs/sq.ft.
The Ateco Ultimate Pontoon
Aluminum Internal Floating Roof has
200 mm (8ins) dia. X 2 mm thick
extruded aluminium alloy pontoons
- 0.5 mm thick aluminium sheet.
Designed to withstand loads up to
500 lbs/sq. ft
The pontoons are an integral
component of the basic structure
The pontoons are suspended
from the basic structure

21. The Ateco Ultra 2000 Internal Floating Roof is an
upgrade to the very successful ATECO Ultimate
Internal Floating Roof can accommodate
storage tanks with a high frequency of filling
and discharge of product.
Designed to withstand loads up to 1000 lbs/sq. ft.
Installation all ATECO pontoon type
of internal floating roofs is quick and
efficient as it is sent to site
completely prefabricated, no
welding is required to complete
the assembly and all component
parts fit through a standard tank
24 ins shell manway.

25. ATECO offer the following design of full contact internal floating roof: -
ATECO OpenDeck - Pan Type
The ATECO OpenDeck Internal Floating Roof features include:-
 manufactured in either aluminum or stainless steel
 product vapors or liquid cannot leak ınto or be trapped in buoyancy chambers
 completely prefabricated panels are bolted together at site
A very efficient and cost effective IFR compatible with most stored products.

26. allows roof height adjustments to be
completed from the outside the tank
no leg structure under the roof - cleaning
inspection and repairs to the tank bottom are
simplified
more efficient in the control of vapour
emissions as the roof does not have the
penetrations in the deck sheets to
accommodate the roof legs.
ATECO internal floating roofs can be suspended from
cone roof tanks or aluminum dome roofs:-

27. Primary
and Secondary
Seals
for
External
Floating Roof
Tanks

28. . The ATECO Weighted Pantograph Primary
Seal comprises 1.6 mm galvanised or
stainless steel shoe plates which are held
against the tank shell by a system of levers
and heavy weights.
A vapour barrier is then fastened between
the top of the shoe plates and the top of
pontoon on the floating roof
The pushing force is gravity and since
this is always present this type of seal has
proved to me robust and very reliable.

29. However, installation, maintenance and repair is relatively difficult and for
this reason ATECO has introduced the ATECO Pusher Plate Primary Seal
which is commonly referred to as a “top mounted seal” meaning that this
seal can be initially installed and subsequently accessed for maintenance
and repair from the top of the floating roof.
The Ateco Pusher Plate Primary Seal comprises 1.6 mm
galvanised or stainless steel shoe plates which are
held against the tank shell by hardened staınless steel
spring steel plates.
Installation, maintenance and repair is
relatively straight forward since all parts of the
seal can be access from the top of the floating
roof and even with the tank in service.

30. The Ateco Double Compression Plate Seal is a very efficient
and most cost effective seal system since it comprises a primary and
secondary seal in the same unit.
Features include 1.6 mm thick independent and overlapping
galvanized or 1.2 mm stainless spring steel compression plates. A
continuous vapour barrier membrane can be included.
The ATECO Foam Log Primary Seal comprises a 2 mm thick
PVC Nitrile envelope surrounding ccompressible polyurethane foam.
The main primary seal in the non mechanical category is the Foam Log Seal
The more “pressure points” that are applied to the shoes plates the
more efficient the seal – the ATECO Weighted Pantograph Seal and the
ATECO Pusher Plate Seal have six (6 No) pressure points per plate.

31. ATECO supply a foam dam that bolts on the pontoon rim angle and has the
same hole spacing as the primary and secondary seals, With either 1.6 mm
Galvanized or 1.2 mm Stainless Steel Plates the ATECO Foam Dam meets the intent
of API 650 and NFPA 10 however, to fully comply with NFPA 10 we also offer 3.5
mm thick plates for bolting or welding to the tank roof.
Mechanical seals can be fitted with a wax scraper and where highly volatile products are stored a drip
curtain can be attached and this has the effect of enhancing the sealing efficiency in areas where seal tip
to shell contact is less than perfect due to protruding welds or severe corrosion of shell plates.
ATECO have a range of seal tips
manufactured from composite material
compatible with most stored products
The ATECO Compression Plate Secondary Seal with 1.6 mm independent
and overlapping galvanized or 1.2 mm stainless steal spring steel plates is the
most popular secondary seal and can be used with all the ATECO primary
seals. A continuous vapour barrier membrane can be supplied

32. A mechanical seal has lower frictıon resistance and
Ateco has developed a lighter weight mechanical
pusher plate type of primary seal specıfıcally for
use with an aluminum internal floating roof.
The Pusher Plate Prımary Seal ıncorporates three
hardened staınless steel plates provıdıng sıx
pressure poınts on each 1.6 mm thıck shoe plate.
Thıs ıs a top mounted seal whıch means ıt can be
ınıtıally ınstalled and subsequently maıntaıned
from the top of the ınternal floatıng roof.
The Ateco Pusher Plate Prımary Seal ıs compatıble wıth most stored products and wıll maıntaın a very tıght
seal over a rım gap varyıng from 100 mm to 300 mm with six pressure points on each shoe plate.
We also ıncorporarte ‘faıl save’ features to prevent damage to the seal and tank ın the event that the
workıng tolerances of the rım gap are exceeded.
