Promat DURASTEEL® High Performance Systems
WHAT IS Promat DURASTEEL®?Promat DURASTEEL® is a composite panel of fi bre reinforced cement mechanically bonded to punched steel sheets on both outer surfaces. It is classed as ‘non-combustible’ to BS 476: Part 4: 1970 and A1 to Clause 10 of BS EN 13501-1:2002. Promat DURASTEEL® is both highly impact and moisture resistant.
Promat DURASTEEL® has been developed and supported through rigorous testing for use in barriers, door and ceiling applications, with a wide range of specifi cations available.
Promat DURASTEEL® systems combine lightness, strength, impact, blast resistance and durability with exceptional fi re resistance. In addition, Promat DURASTEEL® can also withstand the effects of fi refi ghters’ hoses.
Promat DURASTEEL® systems have been used successfully across the industry for many years, including large rail, metro and airport projects, as well as military developments and commercial, pharmaceutical and petrochemical facilities.
Promat has developed DURASTEEL® to provide an effective blast resistant solution to constructions in a wide range of industrial applications, including power generation and anti-terrorist installations.
HIGH PERFORMANCE SYSTEMSPromat DURASTEEL® walls and partitions can be designed and installed in various layout and framing options to meet a multitude of needs. In today’s construction markets the need for systems which can perform multi-functional roles, whilst capable of allowing for fast track and cost effective installation, are of prime importance.
The Promat DURASTEEL® partition and wall systems can easily fulfi l all of these roles. Promat DURASTEEL® walls have resistance to extreme impact, before, during and after exposure to fi re. This ensures that under use, they suffer no damage from the burden of every day exposure within, for instance, warehouse situations. Under fi re conditions they protect and maintain compartmentation and after a fi re they ensure a building remains secure until remedial work can be undertaken.
Promat DURASTEEL® systems can be installed quickly; on most occasions they have no requirement for additional foundations or other special construction works. Installation is a “dry” trade, thus there is no disruption of other trades working in the same areas, allowing faster project completion.
Promat DURASTEEL® systems can offer both integrity only or integrity and insulation. Walls can be designed for high blast resistance and meet most of the generally recognised fi re curves, including cellulosic and hydrocarbon.
Promat DURASTEEL® systems combine extremely high levels of fi re, impact and water resistance. They are proven to withstand the most demanding environments, temperature extremes, hostile elements and can resist high thermal shock, such as high pressure water hoses.
Promat DURASTEEL® partition and wall systems can be used in applications such as separation of hazardous areas, shielding for valve actuators, protection of escape routes and tunnels, construction of refuge areas, compartmentation within buildings and storage areas for hazardous goods or equipment protection.

DESIGN AND TECHNICAL SERVICESWith over 100 years of combined experience, our dedicated technical and sales
support teams are available to provide information and assistance to help in the
design and installation of Promat DURASTEEL® systems.
SYSTEM INSTALLATIONAfter a site survey, installers will provide fully designed working drawings. Promat will
supply the fi re resisting sheets, doors and penetration seals, which provides a single source
and responsibility.
All elements are tested as a combined system to ensure compatibility, with one source of
warranty. Access panels for maintenance or fi re stopping of penetrations through the barrier
can be included in the system estimate.
Promat DURASTEEL® systems are installed by experienced, licensed installers. Once the work
is complete, the system undergoes a thorough check before the installation is issued with a
Certifi cate of Conformity.
Our licensed installers are all assessed under the FIRAS third party accreditation scheme.
REGULATORY REFORM (FIRE SAFETY) ORDER 2005 (RRFSO)Fire safety law changed in October 2006. The emphasis of the new law is prevention of fi res
and reduction of risk, and makes it the property owner’s responsibility to ensure the safety of
everyone who uses their premises and the immediate vicinity.
The Department for Communities and Local Government (DCLG) have produced a set of
guides to advise the responsible person how to comply to the fi re safety law, help them to
conduct a fi re risk assessment and identify general fi re precautions that will need to be put in
place.
Failure to meet the requirements of these new regulations could lead to prosecution, which
could then result in hefty fi nes or even imprisonment. The Order replaces any previous fi re
legislation. Any fi re certifi cates issued under the Fire Precautions Act 1997 ceased to have effect
from 1st October 2006.
Promat provides a free advice service to help parties within the building industry to make the
right choices in fi re safety. Promat’s technical department monitors any changes and tests
systems in order to offer solutions to help comply with fi re safety legislation.

SYSTEMS AVAILABLESome common partition systems constructed from Promat DURASTEEL® are shown on the
following pages. When considering the design of walls, it is essential to consider the section
size of the steel framing in conjunction with the wind loading factors, expansion allowance,
together with the height and span of the wall, to ensure that under both ambient and fi re
conditions, the wall will provide the necessary design performance. The basic framing system
comprises of lightweight steel sections, with a nominal 3mm thickness, dependant on the other
design factors etc. All framing is either bolted, screwed or welded into position, dependant on
location, performance parameters and design requirements.
Where a cold smoke seal is required, the boards must be bedded on PROMASEAL® fi re rated
silicone or PROMASEAL® Intumescent mastic. For demountable wall systems, to ensure
sealants do not act as adhesives, a cold smoke seal composed of a 2mm thick strip of Promat
PL Intumescent strip can be applied. For integrity only systems, Promat DURASTEEL® walls
have been tested with the framework on both the exposed and unexposed face to fi re, in
order to show that the frame can be exposed without detriment to the fi re performance of the
system.
The framing for the Promat DURASTEEL® wall systems must be securely fi xed back to a
substrate (concrete, masonry or steel) that has an equal or better fi re performance than
the designed wall. All fi xings must be non-combustible, and must be listed in the approval
documents. Expansion bolts used to fi x framework should be steel, not aluminium or plastic.

LOW RADIATION FIRE WALLLow radiation fi re wall for constructions that require a high degree of stability, integrity
and insulation as measured upon the unexposed surface of the wall is not critical, but
where heat radiation from exposed to unexposed face could be of importance. Promat
DURASTEEL® low heat radiation walls offer a lightweight construction, which is very narrow
across its thickness.
Used in conjunction with the Promat DURASTEEL® pallet racking fi re barrier system,
this wall offers increased warehousing space and allows for racking to be placed practically
against the Promat DURASTEEL® wall itself.
Single layer Promat DURASTEEL® fi re walls can be constructed using framing of either steel
channels, Tee sections or back to back angle sections. The type of framing system and
the dimensions of the steel sections will depend on the performance requirements of the
wall in terms of wind load, fi re performance and impact resistance. In these circumstances,
Promat DURASTEEL® walls provide a bespoke solution.

PROTECTED ZONES, SPANDREL PANELS, SMOKE SCREENSSmoke kills more people in fi res than heat, fl ames or structural collapse. It is therefore
recognised that occupant safety in a fi re can be greatly improved by providing an
effi cient smoke extraction system. Part of an engineered smoke control system may
involve the provision of smoke reservoirs, the use of smoke channelling screens and
smoke curtains.
Testing standards for smoke control equipment smoke curtains and screens shall meet
the requirements of BS 7346: Part 3: 1990, which requires the screen to withstand a
fi re temperature of 600°C +/-20°C for a minimum of 30 minutes.
The Promat DURASTEEL® system has been tested to the criteria of BS 476:
Part 20, which has much higher exposure temperature requirements and it provided a
performance in excess of 240 minutes. Promat DURASTEEL® barriers can also be
used in position as horizontal “wings” (protected zones) at the head and to the sides of fi re
walls, forming an added “band” of protection at the junction with other substrates (as detailed
in the FPA Design Guide Supplement 2004). This makes it exceptionally diffi cult for fi re to
breach a roof and thus leap over the top of, or around, the fi re resistant wall system.
Promat DURASTEEL® can also be used within spandrel panel systems, positioned at the end
of fl oor slabs in order to prevent fi re bridging gaps between fl oor slabs and curtain
wall systems.
VALVE PROTECTION ENCLOSURESThe ability to isolate storage areas or to direct highly combustible fuels away from
a heat source through a series of protected valves is paramount in the event of fi re.
When subjected to high temperatures, the plastic parts of a valve can easily be rendered
inoperative, resulting in the valve’s inability to divert or arrest fl ow.
Promat DURASTEEL® can offer different methods of protection for valves, dependent on
the requirement.
In certain circumstances, it may be suffi cient to protect the valve with a fi re resistant
shielding. In other cases, a more substantial form of protection may be required. In these
circumstances, the valve can be fully enclosed within a Promat DURASTEEL® valve actuator
box. These boxes have been designed to ensure the valve temperature cannot rise by
more than 30°C in 15 minutes, or 30°C in 30 minutes, depending on the type of Promat
DURASTEEL® system installed.

INSULATED FIRE WALLFire walls are used in constructions where high insulation as well as stability is required during a
fi re. Promat DURASTEEL® insulated fi re walls are designed to prevent the passage of heat from
a fully developed fi re on the exposed face. The maximum permitted temperature rise allowable
on the surface of the unexposed face is 140°C as a mean temperature over all the surface, or a
maximum temperature rise of 180°C at any one point over all the surface.
Insulated wall constructions should be used in areas where the following may occur:
● Escaping personnel or fi re fi ghters may have bodily contact with the wall surface.
● If used as a wall lining to any escape route, for instance as an access tunnel within a factory.
● If there are any volatile chemicals or materials stored within the vicinity of the fi re wall and
which may ignite at low temperatures.
● There is a need to improve compartmentation beyond simple integrity.
There are a number of methods of constructing insulated wall systems. Each option has its
own benefi ts. The type of system, thickness and density of the rock wool and cover strips, if
required, are all dependent on the fi re and physical performance required from the system.
FIREBLAST® WALLDesigned specifi cally to protect personnel and equipment from the effects of explosion,
fi re, impact, and the effects of smoke and fumes in hazardous environments, such as offshore
platforms, petrochemical installations, chemical plants, military establishments, civil defence
works and hazardous process plants.
Additional features of FIREBLAST® fi re and blast resistant walls:
● Blast resistant, tested from 0.3 to 2 bar over pressure.
● Resistant to hydrocarbon fi res, tested to H120.
● Impact resistant to 4000J after 180 minute fi re test. In accordance with DIN 4102 Parts 2
and 3 requirements
● High energy absorption.
● Hose stream resistant to a 5 bar high pressure hose (ASTM E119).
Unlike many fi re and blast resistant materials, Promat DURASTEEL® is non-combustible and will
withstand an explosion followed by a prolonged fi re and still be unaffected by hose stream fi re
fi ghting. Its integrity remains unimpaired, ensuring continued protection against fi re, impact and
moisture as well as preventing the escape of smoke and toxic gases. Promat DURASTEEL®
systems are tested up to H120 fi re rating, and the systems can be designed to suit specifi c
project performance requirements.
All FIREBLAST® walls are individually tailored to suit specifi c project performance requirements,
please consult the Promat Technical Services Department for specifi cation and construction details.

240 MINUTE DURASTEEL® PROTECTED ZONE (E 240 - EI 15)
If a fi re breaks out near the area where a compartment wall meets a roof, there is a risk
that it will spread over the roof to the adjoining compartment. To reduce the risk, Approved
Document B requires protection to be installed to a protected zone of the roof 1500mm either
side of the compartment wall. However, for more onerous circumstances, the FPA Design
Guide suggests a minimum of 2500mm, or up to 5000mm dependent upon the orientation of
the ridge and the presence of a sprinkler system.
A DURASTEEL® protected zone detail is required for instances where a DURASTEEL®
fi re barrier (acting as a compartment wall) abuts a roof system. Please contact Promat UK
Technical Services department for further information.

(and at right angles to the MF5 ceiling sections), but with staggered joints in both directions
between layers.
100mm wide PROMATECT® -250 cover strips (8) are fastened behind the transverse joints
between the MF5 sections of the PROMATECT® -250 boards, using 32mm drywall screws at
nominal 250mm centres, with the screws at 25mm from edge of the board, and 50mm from
ends of the cover strips.
Since drop-rods support the ceiling, the length and width of ceiling membrane
is unrestricted.

Promat DURASTEEL® High Performance Systems
Heathrow Terminal 5The quality of Promat DURASTEEL® and our specialist installers were tested to the full during the construction of Heathrow Terminal 5. Promat supplied 100,000m2 of DURASTEEL® to the £4.2m billion project, its largest specifi cation to date.
Designed by the Richard Rogers Partnership, T5 is being hailed as a new landmark for London. It can accommodate 30 million passengers a year. But there’s far more to it than just a building. As well as the vast new terminal – which could fi t 50 football pitches – and its two satellites, the project includes 47 aircraft stands, a control tower, a 4,000 space multi-storey car park, a hotel, rail links, a spur road from the M25, even a diversion of two rivers.
Promat’s input includes the largest ever specifi cation of a DURASTEEL® fi re barrier. It is being used in the main terminal building, the satellites and in the railway station – in some areas forming barriers 14m high.
Promat supplied the 100,000m2 of DURASTEEL® in 9.5mm sheet for insulated fi re barriers. It features prominently below apron level, lining the tunnel-like service corridors, the cavernous baggage handling areas, lift pits, workshops and plant rooms. The continuous barriers of silver Promat DURASTEEL®, punctuated by apertures for doors and services, provides a purposeful presence throughout all these areas.
Promat DURASTEEL® easily met the specifi cation for EI 120 fi re resistance. But that’s not the only reason it was chosen. The system was installed well before the dry envelope stage, so it had to be exceptionally tough and durable.
MACE Solutions – the fi xed price service provider within Mace Infrastructure Sector – are the package contractor responsible for the design and construction of the compartment walls below the main terminal.
And the architects working in partnership with MACE Solutions, Bryden Wood Associates, cite Promat’s technical expertise in helping to develop the specifi cation, including wind loadings for the tall barriers and developing systems such as barriers with a plasterboard facing for offi ce areas.
The Promat DURASTEEL® barriers’ high impact resistance was another key factor. “The barriers must withstand the impact of trolleys and baggage systems,” says project architect Dan Cunliffe. “Promat DURASTEEL® was the best product for the project, based on its versatility across a wide range of performance and other functional criteria.”
The Promat DURASTEEL® walls were constructed from pre-cut kits fabricated in R&S Fire & Security Limited’s factory in Essex, and delivered in meticulously labeled, pre-assembled kit form. They are installed section by section using scissor lifts.
John Allsop, the senior site agent for R&S, says “Promat DURASTEEL® is as easy to install as plasterboard, but of course it’s far more durable and robust.”
“We have a close association with both Promat and MACE Solutions,” says R&S Group’s managing director Keith Barclay. “This proactive relationship has ensured that delivery of the contract has run smoothly and effi ciently for the client BAA. It’s on time, within budget and in accordance with the T5 project principles.”
CASE STUDIES
“ Before the roof went on,
rain water was running
down the DURASTEEL®
walls for months on end
without any detrimental
effect on the integrity
of the product.”
says John Allsop,
site agent for Essex-based R&S
Fire & Security Ltd, the specialist
sub-contractor responsible for
its installation.
“ The system selection
process identifi ed Promat
DURASTEEL® as the most
appropriate partitioning
material based on the fi re
rating, its durability and
ability to withstand the
environmental conditions
that exist during the early
phases of construction”

White City Development, West LondonThe tallest ever DURASTEEL® fi rewall in the UK is providing protection for power plants within the refurbished Grade ll-listed west DIMCO building, a central component of the regeneration.
Westfi eld London is a retail, leisure and lifestyle development by the world’s largest retail property group, Australian-owned Westfi eld. The development is a 46-acre site between Shepherd’s Bush and White City tube stations, until recently an industrial wasteland. The £1.6 billion development contains the largest shopping centre in Europe along with leisure facilities, 14-screen cinema, a spa and gymnasium, bars, restaurants, new transport links and affordable housing. Westfi eld London aims to become the capital’s premier retail, leisure and lifestyle destination.
On Westfi eld London, Promat DURASTEEL® came through with fl ying colours. The Grade II-listed DIMCO building was built more than 100 years ago, originally to house Europe’s fi rst electricity generating facility. Its refurbishment has been an ambitious and complex task involving extensive temporary works for the complete roof and roof structure replacement. A Promat DURASTEEL® barrier provides 120 minutes fi re compartmentation protection for the electricity sub-station within the west DIMCO structure, which supplies power to the new development.
At 25m high, the barrier installed is the tallest to date, and one of the most complex in terms of detailing and installation. Promat’s expertise was key.
London based Towns-Wadey is Westfi eld’s building contractor for the DIMCO project. Design Manager James Wraight said: “The DURASTEEL® wall has a bespoke design which is completely independent from the listed DIMCO building fabric, new roof and roof structure, offering 2 hour fi re compartmentation and fi re protection to the supporting steel structure. To keep the wall independent, we worked closely with Promat, specialist contractor Sharpfi bre and the Architect to achieve working movement details whilst maintaining a practical and safe installation process. We were able to use the system to hide the complex supporting steel structure, eliminating further fi re protection providing value engineering options for our client”.
“DURASTEEL® was the right product for the job and Promat offered good design advice,” says Sharpfi bre.
