Promat DURASTEEL®
Promat DURASTEEL®
Promat DURASTEEL® is a high-performance composite panel made of fiber-reinforced cement bonded to steel sheets. It is non-combustible, impact, and moisture-resistant, designed for use in barriers, doors, and ceilings. It is widely used in various industries, including rail, metro, airport projects, and military developments, due to its fire and blast resistance.
The material is classified as non-combustible with a Class 0 building regulations classification. It has a thermal conductance of 60 W/m2K at 20°C and a coefficient of expansion of 15 x 10-6 m/mK. The boards come in various thicknesses and sizes, with specific mechanical properties such as flexural strength and modulus of elasticity.
Promat offers comprehensive technical support for the design and installation of DURASTEEL® systems. Installation is performed by licensed installers, ensuring compatibility and compliance with fire safety standards. The systems are designed to be installed quickly without the need for additional foundations.
The order emphasizes fire prevention and risk reduction, making property owners responsible for fire safety. Promat provides guidance to comply with these regulations, helping to avoid legal penalties.
Promat DURASTEEL® systems have undergone extensive testing to meet UK and international standards, including BS 476 and approvals from Factory Mutual, Underwriters Laboratories, and others. The systems are certified for high fire resistance and impact resistance.
Promat DURASTEEL® offers up to EI 240 and E 360 fire ratings, impact resistance, water resistance, and minimal smoke emission. It is lightweight, relocatable, and suitable for retro-installation, with a service life of over 40 years.
These walls provide stability and insulation, reducing heat radiation. They are lightweight and allow for increased warehousing space.
Promat DURASTEEL® systems can be used to create smoke control systems, improving occupant safety by providing smoke reservoirs and channelling screens.
Promat DURASTEEL® systems are designed to provide high fire resistance, tested to BS 476: Part 20, with performance exceeding 240 minutes. They can be used as barriers, horizontal wings, and within spandrel panel systems to prevent fire spread.
Promat DURASTEEL® offers protection for valves, ensuring they remain operational during fires. Options include fire-resistant shielding or full enclosures to limit temperature rise.
These walls prevent heat passage during a fire, with a maximum temperature rise of 140°C on the unexposed face. They are suitable for areas with potential human contact or volatile materials.
Designed for explosion and fire protection, these walls are blast-resistant, hydrocarbon fire-resistant, and impact-resistant, maintaining integrity even after prolonged exposure.
Promat DURASTEEL® is used across various sectors including industry, transportation, commerce, and power stations, providing robust fire protection and maintaining operational integrity.
Specifications include channel sizes and configurations for different fire resistance levels, ensuring effective compartmentalization and protection.
Promat DURASTEEL® is self-finished and requires minimal maintenance. Damaged panels should be replaced to maintain fire performance.
For areas where compartment walls meet roofs, protected zones are required to prevent fire spread, with specifications varying based on risk factors.
- Channel Sizes: Vary based on barrier height, ranging from 80mm x 60mm x 3mm for heights up to 6m, to two 200mm x 60mm x 3mm channels back to back for heights up to 15m.
- Fire Resistance: Two main systems are described: E 240 – EI 120 with 240 minutes integrity and 120 minutes insulation, and EI 240 with 240 minutes integrity and insulation.
- Sound Insulation: Estimated sound reduction ranges from 42dB to 56dB depending on the configuration.
- Installation: Channels are fastened with M10 or M12 steel anchors, with specific spacing and jointing requirements to ensure structural integrity and fire resistance.
- Fire Resistance: Various configurations offer fire resistance from 120 to 240 minutes, with integrity and insulation ratings specified for different fire attack scenarios.
- Channel and Board Installation: Channels are supported by steel drop rods, and DURASTEEL® boards are fastened with specific screws and spacing to ensure proper installation.
- Expansion Allowance: Required for channels longer than 4m, with specific guidelines for fire attack from above or below.
- Use of steel angle cleats and bolts for joining channel members.
- Rock wool infill and fillet strips are used for additional insulation and sound reduction.
- Specific guidelines for fixing screws and joint overlaps to ensure structural and fire integrity.
The document outlines the specifications for DURASTEEL® suspended ceiling membranes, focusing on fire resistance and structural integrity. The ceiling systems are designed to withstand fire attacks from above or below, with varying methods providing up to 240 minutes of fire resistance.
1. Channels: Minimum dimensions are specified for channels, with options including 60mm x 150mm x 60mm x 3mm and 80mm x 60mm x 3mm. Channels are either welded or joined with steel angle cleats.
2. Drop Rods: Steel drop rods support the ceiling, with tensile stress limits set to ensure structural integrity during fire exposure.
3. Board Joints: Longitudinal board joints align with primary channels, while transverse joints are backed by steel channels.
The systems provide up to 240 minutes of integrity and insulation against fire. Specific configurations are detailed for fire attacks from above, below, or both.
Rock wool insulation is used extensively, with layers overlapping by at least 150mm to ensure coverage and effectiveness. The insulation density is specified at 140 kg/m3.
1. Fastening: M10 or M12 steel expanding anchors are used for perimeter channels, with M5.5 steel self-drill and tap Tek screws for board fastening.
2. Expansion Allowance: An expansion allowance of at least 6mm per metre is required for primary channels longer than 4m, applicable for fire attacks from both above and below.
The document specifies that the length and width of the ceiling membrane are unrestricted due to the support provided by drop rods. The tensile stress within the rods should not exceed 6N/mm2 for fire ratings up to 240 minutes, with an increase to 10N/mm2 permissible for 120-minute ratings.
The DURASTEEL® ceiling systems are robust solutions for fire protection, offering detailed specifications for installation and performance. The document provides comprehensive guidelines to ensure the systems meet the required fire resistance standards.
The document outlines the specifications for DURASTEEL® systems, including the use of horizontal board joints with internal steel cover strips and specific fastening methods using M5.5 steel self-drill and tap Tek screws. It details the requirements for partition studs based on height, specifying channel sizes and acoustic insulation ratings.
For partitions up to 6m, 80mm x 60mm x 3mm channels are used, while for heights between 6m and 15m, 150mm x 60mm x 3mm channels are required. The document specifies the need for expansion allowances above 4m and details the construction of self-supporting and suspended ceiling options using DURASTEEL® and PROMATECT® panels.
It is recommended that DURASTEEL® sheets require two fixings per corner, with specific fixing patterns and allowances for tolerances. The document also emphasizes the importance of offsetting vertical joints to prevent straight-through paths for hot gases.
The document includes case studies of DURASTEEL® applications, such as the Heathrow Terminal 5 project, where 100,000m2 of DURASTEEL® was used for fire barriers, and the White City Development, where the tallest DURASTEEL® firewall in the UK was installed. These case studies highlight the material's durability, fire resistance, and ease of installation.

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:...
