  • 5. Promat DURASTEEL® High Performance Systems DESIGN AND TECHNICAL SERVICES With 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 INSTALLATION After a site survey, installers will provide fully designed working drawings. Promat will supply the fire 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 fire 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 Certificate 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 fires 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 fire safety law, help them to conduct a fire risk assessment and identify general fire 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 fines or even imprisonment. The Order replaces any previous fire legislation. Any fire certificates 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 fire safety. Promat’s technical department monitors any changes and tests systems in order to offer solutions to help comply with fire safety legislation. 5Durasteel Brochure.indd 5 28/10/08 15:33:00

When considering the design of walls, it is essential to consider the section • Easily relocatable size of the steel framing in conjunction with the wind loading factors, expansion allowance, • Hose-stream resistant together with the height and span of the wall, to ensure that under both ambient and fire • Mechanical or seismic conditions, the wall will provide the necessary design performance. The basic framing system vibration resistant 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 • Suitable for retro-installation location, performance parameters and design requirements. • Low sound transmission Where a cold smoke seal is required, the boards must be bedded on PROMASEAL® fire rated • Good acoustic insulation performance 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 fire, in order to show that the frame can be exposed without detriment to the fire performance of the system. The framing for the Promat DURASTEEL® wall systems must be securely fixed back to a substrate (concrete, masonry or steel) that has an equal or better fire performance than the designed wall. All fixings must be non-combustible, and must be listed in the approval documents. Expansion bolts used to fix framework should be steel, not aluminium or plastic. 8Durasteel Brochure.indd 8 28/10/08 15:33:07
  • 9. Promat DURASTEEL® High Performance Systems LOW RADIATION FIRE WALL Low radiation fire 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 fire 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® fire 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, fire performance and impact resistance. In these circumstances, Promat DURASTEEL® walls provide a bespoke solution.

  • 10. Promat DURASTEEL® High Performance Systems PROTECTED ZONES, SPANDREL PANELS, SMOKE SCREENS Smoke kills more people in fires than heat, flames or structural collapse. It is therefore recognised that occupant safety in a fire can be greatly improved by providing an efficient 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 fire 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 fire 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 difficult for fire to breach a roof and thus leap over the top of, or around, the fire resistant wall system. Promat DURASTEEL® can also be used within spandrel panel systems, positioned at the end of floor slabs in order to prevent fire bridging gaps between floor slabs and curtain wall systems. VALVE PROTECTION ENCLOSURES The 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 fire. 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 flow. Promat DURASTEEL® can offer different methods of protection for valves, dependent on the requirement. In certain circumstances, it may be sufficient to protect the valve with a fire 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. 10Durasteel Brochure.indd 10 28/10/08 15:33:13

  • 12. Promat DURASTEEL® High Performance Systems INSULATED FIRE WALL Fire walls are used in constructions where high insulation as well as stability is required during a fire. Promat DURASTEEL® insulated fire walls are designed to prevent the passage of heat from a fully developed fire 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 fire fighters 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 fire 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 benefits. The type of system, thickness and density of the rock wool and cover strips, if required, are all dependent on the fire and physical performance required from the system. FIREBLAST® WALL Designed specifically to protect personnel and equipment from the effects of explosion, fire, 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® fire and blast resistant walls: ● Blast resistant, tested from 0.3 to 2 bar over pressure. ● Resistant to hydrocarbon fires, tested to H120. ● Impact resistant to 4000J after 180 minute fire 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 fire and blast resistant materials, Promat DURASTEEL® is non-combustible and will withstand an explosion followed by a prolonged fire and still be unaffected by hose stream fire fighting. Its integrity remains unimpaired, ensuring continued protection against fire, impact and moisture as well as preventing the escape of smoke and toxic gases. Promat DURASTEEL® systems are tested up to H120 fire rating, and the systems can be designed to suit specific project performance requirements. All FIREBLAST® walls are individually tailored to suit specific project performance requirements, please consult the Promat Technical Services Department for specification and construction details. 12Durasteel Brochure.indd 12 28/10/08 15:33:18
  • 13. Promat DURASTEEL® High Performance Systems SYSTEM APPLICATIONS Promat DURASTEEL® FOR INDUSTRY Manufacturing & Warehouse Complex The need for effective protection of personnel, plant, stores and property in industry is vital. Promat DURASTEEL® is proven to contain fire within compartments of a production area or storage facility, thus allowing evacuation of personnel, minimising disruption of processes and preventing the destruction of valuable stocks. As an indication of the effectiveness of Promat DURASTEEL® these photographs show a production facility before and after a fire. The Promat DURASTEEL® wall separating two sections of the factory performed exactly as designed. Indeed, the bottling plant on the unaffected side of the barrier was operational again within 2 days of the fire, therefore minimising the effects of the incident as much as possible. Promat DURASTEEL® FOR TRANSPORTATION INFRASTRUCTURE Underground Rail System Promat DURASTEEL® is lightweight, robust and ideally suited to the external environment of all trackside, station and rolling stock fire protection requirements. It is also widely used in road and rail tunnels. Knights of Old DURASTEEL® barrier 13Durasteel Brochure.indd 13 28/10/08 15:33:18

  • 17. Promat DURASTEEL® High Performance Systems 240 MINUTE DURASTEEL® PROTECTED ZONE (E 240 - EI 15) If a fire 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® fire barrier (acting as a compartment wall) abuts a roof system.

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 efficiently for the client BAA.
