An attractive and economic range of steel roof profiles to meet the aesthetic requirements of the designer.
Trisobuild® systems comprise of a pre-finished steel trapezoidal liner profile, a spacer system, an insulation layer and a Colorcoat® pre-finished steel external weathering profile. The wide range of profiles offer total design flexibility.
Trisobuild systems have excellent sustainability credentials, for example they are all certified to BES 6001, the BRE responsible sourcing standard. The system can also boast low levels of air permeability and good thermal performance over the life of the building, which is due to the quality of components used and proven performance. This reduces energy costs, carbon emission rates and facilitates compliance with Building Regulations.

The Colorcoat® pre-finished steel products that our roof profiles are manufactured from have been tested in accordance with BS EN 14782 to provide the specifier with the peace of mind of specification declarations and that the components meet the legal requirements set out in the Construction Products Regulations (CPR) and are affixed with a CE mark.
Easily handled on site without specialist mechanical equipment, due to its lightweight components. This is important on sites with limited access.
Loss Prevention Certification Board (LPCB) approval to LPS 1181 part 1 for fire performance, helps to lower insurance premiums.
Fire resistance performance of up to 60 minutes insulation and 4 hours integrity are achievable, with standard installation methods.
Full traceability of all component materials and certified ‘very good’ to BRE’s responsible sourcing standard BES 6001.
Certification to BES 6001 provides independent evidence of our corporate responsibility, and helps increase credits under the Responsible Sourcing of Materials section of BREEAM.
An Environmental Product Declaration (EPD) is available for all the Trisobuild® system solutions.
Manufactured in factory conditions operating to quality management standard BS EN ISO 9001:2015, environmental management standard BS EN ISO 14001: 2015 and occupational health and safety management scheme BS EN ISO 18001:2007.

General reference All measurements throughout this brochure are referenced in mm unless stated otherwise. Technical illustrations are not to scale.
Load/span figures The load/span information in the table below is based on a total load of 1.20kN/m2 and a deflection limit of L/200 and should be used as a guide only. Our full load span tables are available for download below. If you have any further questions please do not hesitate to contact our Technical Team.
Curving Although the self curve minimum values shown have been chosen with aesthetics in mind some stress marking may be present in the profile trough. Self curved panel ends laps will ‘bird mouth’ slightly, therefore long sheet lengths are recommended to reduce the number of end laps. The factory curved data relates to a single convex curve. Information regarding double or wave curves please contact the technical department.
Our Platinum® Plus system guarantee offers coverage for up to 30 years. Simply fill in your project details using our easy-to-use online specification tool or contact us directly.
We understand that complex buildings need tailored solutions, so our online specification tool has been designed by our technical team to help you create the right specification to suit the needs of your project, making sure all roofing and cladding components listed and are compatible and perform as a system. It also stores all the specifications you create for ease of access in ‘my projects’.
Creating a Platinum® Plus specification give you free access to our technical team that will support you from design to completion – including those all-important final checks during installation.
Platinum® Plus incorporates only the highest quality components that are designed to do what they say but also provide you with unrivalled choice and flexibility in the specification of your building envelope. The many benefits and reassurance it provides is what sets it apart from all other guarantees, making it the number one choice for complete peace of mind to truly lower the cost of ownership throughout the life of the building.
The Platinum Plus system guarantee needs to be registered by the specifier prior to the tender package being distributed. To find out more click here, alternatively please contact our technical team so that we can help you to guarantee the longevity of your building on +44 (0) 1244 892199.
Thermal performance
Trisobuild® systems comply with the Building Regulations (Approved Document Part L2 – England Wales & Technical Handbook 6 – Scotland). All quoted system U-values and construction ‘psi’ and f values have been computer modelled in accordance with EN ISO 10211 as stated in MCRMA Technical Note 14 by trained and experienced technical engineers.
Fire performance
All Trisobuild systems when used as a roof achieve a Grade AA rating in accordance with BS 476-3, which tests for external surface spread of flame and fire penetration (AA is the best result achievable) or are “deemed to satisfy without the need for testing” in accordance with Commission Decision 200/553/EC.
The Colorcoat® pre-finished steel products used within the Trisobuild system meet the requirements the Building Regulations Approved Document B for internal and external surfaces.
Trisobuild systems can also offer a Grade EXT-B and EXT-A approval by the LPCB together with fire resistance of up to 60 minutes insulation and 4 hours integrity.
Trisobuild® systems can offer a wide variety of sound reduction and sound absorption solutions, using variations in liner and insulation specification.
Many assemblies have been tested through independent acoustic laboratories. We have further test data and the ability to offer predicted performance ratings using software developed by the Department of Applied Acoustics, University of Salford and the Metal Cladding and Roofing Manufacturers Association (MCRMA).
Please contact us and provide details of your requirements to the technical department and our engineers will work with you to develop a solution to achieve the performance levels necessary.
