GRP Fire Retardant Profiles
Engineered Composites supplies GRP fire retardant structural profiles manufactured using halogen-free resin systems formulated to suppress flame spread and reduce smoke generation. Certified to EN 13501-1:2018 classification B, S1, D0 and independently tested by SGS Labs, they comply with BS EN 13706 E17/E23 grade and deliver the same structural performance as standard GRP profiles with verified fire classification.
Fire retardant GRP profiles offer the same corrosion resistance, electrical non-conductivity, and lightweight handling as standard grades, making them the correct specification for enclosed environments where fire safety regulations are stringent and where conventional steel would corrode or create a conductivity risk. Available in beams, channels, angles, box sections, tubes, and rods in grey or yellow from stock.
EN 13501-1:2018 Certified GRP Fire Retardant Structural Profiles
GRP fire retardant profiles are manufactured using isophthalic vinyl ester or phenolic resin systems specifically formulated to inhibit flame propagation and reduce smoke generation in the event of fire. Standard profiles are certified to EN 13501-1:2018 classification B, S1, D0, independently tested by SGS Labs, and comply with BS EN 13706 E17/E23 grade. This provides the documented fire performance evidence required by specifiers working to Network Rail standards, building regulations, and data centre fire safety codes.
The profiles are available in all standard pultruded shapes including I-beams, channels, equal angles, square hollow sections, tubes, and rods. Where alternative fire classifications are required, other grades are available on request. Confirm the exact classification needed at enquiry stage.

Certified Fire Performance for Enclosed Environments
EN 13501-1:2018 Class B, S1, D0 classification with independent SGS Labs test documentation provides the compliance evidence required for rail, tunnel, data centre, and public building specifications.
Non-Conductive in Safety-Critical Applications
GRP fire retardant profiles are electrically non-conductive throughout, making them the correct choice for electrical switchrooms, substations, underground rail infrastructure, and data centre structural framing where steel creates a conductivity hazard.
Same Structural Performance, Higher Fire Assurance
Fire retardant grades comply with BS EN 13706 E17/E23 and deliver the same mechanical properties as standard GRP profiles. Specifiers do not have to trade structural performance for fire compliance.
Fire Retardant GRP Profiles for Rail, Tunnels, Data Centres, and Public Buildings
Rail and Underground Environments
Fire retardant GRP profiles are used in station platform structures, tunnel walkways, and underground rail infrastructure. ECL holds RISQS accreditation and can confirm the specific fire classification required for Network Rail projects.
Data Centres
FR grades are used in data centre raised access structures, cable management framing, and equipment support where fire performance requirements are defined by the facility design code. Non-conductive construction supports electromagnetic compatibility requirements.
Public Buildings and Infrastructure
Enclosed public environments including transport hubs, sports facilities, and bridges are subject to fire performance requirements. FR GRP profiles provide structural performance with EN 13501-1:2018 Class B compliance.
Electrical and Oil and Gas Facilities
Switchrooms, substations, petrochemical, and offshore environments combine fire risk with chemical aggression. FR GRP profiles resist both.

Typical Applications for GRP Fire Retardant Profiles
Transport & Rail Infrastructure
Fire retardant GRP profiles for platform structures, depot walkways, and trackside framing where non-conductivity and fire classification are both required.
Chemical & Process Plants
Structural framing, support members, and access platforms in corrosive environments where fire retardancy and chemical resistance must be satisfied simultaneously.
Water Treatment & Pumping Stations
Corrosion-free structural profiles for platform framing, handrail systems, and equipment support brackets in chemically active and constantly wet environments.
Marine & Offshore Installations
Fire retardant and saltwater resistant structural profiles for offshore platform framing, vessel access structures, and coastal facility installations.
Nuclear & Defence Facilities
Non-magnetic, non-conductive, and fire retardant structural profiles for sensitive installations where standard steel or aluminium profiles are not suitable.
Industrial Buildings & Mezzanines
Lightweight fire retardant framing for mezzanine structures, internal walkways, and access platforms where building regulations require a specified fire classification.
Data Centres & Electrical Installations
Non-conductive and fire retardant profiles for cable support framing, raised floor structures, and equipment enclosures in electrically sensitive environments.
Construction & Public Infrastructure
Fire retardant GRP structural sections for public buildings, transport hubs, and infrastructure projects where fire performance standards and corrosion resistance are specified.
