Trimapanel® flat

Insulated, secret-fix, smooth faced wall panel that provides a high-end architectural appearance

Trimapanel® flat is an insulated, secret-fix, smooth faced wall cladding that is quick and easy to install for fast build times. Available in 70mm, 90mm and 120mm insulation thicknesses and bespoke lengths up to 12m to minimise waste and provide U-values down to 0.17W/m2K.

Trimapanel® flat is available in Colorcoat HPS200 Ultra® pre-finished steel in a range of sizes, shapes and colours, and the extensive fabrication options, offers a design flexibility that enables architects to create unique and modern design solutions. The panel can be laid vertically or horizontally. The unique secret-fix joint design allows primary fixings to be hidden from view, which combined with the panel’s flat surface provides outstanding smooth external aesthetics.

Platinum® Plus provides a complete building envelope solution guaranteed for up to 30 years. Designed in collaboration with our innovative supply chain of leading component manufacturers, our comprehensive portfolios of high quality products are fully integrated to provide the widest range of roofing and cladding systems.

The Platinum® Plus system guarantee includes, amongst others, the following components:

  • Trimapanel® flat external smooth surfaced wall panel.
  • Colorcoat HPS200 Ultra® pre-finished steel.
  • Stainless steel fixings.
  • Roof lights.
  • Sealants.
  • Fillers.
  • Fall arrest Systems.
  • Flashings & Gutters.
  • The guarantee is offered directly to building owners, giving a direct link back to Tata Steel as the one point of contact.

For full details of our approved components please contact our technical team on +44 (0) 1244 892199.

To ensure that the building envelope will perform as required by the client, we work with specifiers to tailor a specification that considers the interactions of the components and how they impact the building design and performance. We will then provide a detailed Platinum® Plus specification for use within the project tender package, together with a list of recommended installation contractors.

To guarantee the quality of components used on your building, our team of technical construction experts will visit the site to check for compliance to specification, reducing the risk of any issues arising in the future. Once the project is completed the installer will be required to apply for the guarantee using the supplied forms included in the specification document. Tata Steel will then issue the Platinum® Plus guarantee directly to the building owner.

How to raise a specification?

The Platinum® Plus system guarantee needs to be registered with the specifier prior to the tender package being distributed. Please contact our technical team so that we can help you to guarantee the longevity of your building on +44 (0) 1244 892199.

The Trimapanel® flat system complies with the minimum requirements of the Conservation of Fuel and Power sections of the Building Regulations, Approved Document Part L2, England and Wales and Technical Handbook – Scotland. The panel construction offers highly consistent insulation performance, and the site-formed junctions provide a practical and effective method of ensuring good thermal performance.

Fire safety

The Trimapanel® flat system has been tested to LPS1181-1 and is LPCB approved to both Grades EXT-B and EXT-A. Fire resistance performance of 15 mins insulation and 4 hours integrity is also achievable with enhance fixing and methods, contact the technical department for details. The internal surface of the panel complies with Class ‘O’ in accordance with the Building Regulations when tested to BS 476 Parts 6 & 7 and also achieves a Class B s2 rating in accordance with EN 13501-1.

Following rigorous structural and fire performance testing with FM Global, Trimapanel® flat panels have achieved FM Approvals certification to the following stringent standards:

4480: Class 1 Insulated wall and ceiling panels
4481: Class 1 Exterior wall systems (unlimited height)

Specifying and installing FM Approved products will provides assurance that the products have been objectively tested and confirm to the highest international standards. FM Approved roof and wall panel’s means you can be confident that your building envelope will withstand a broad range of fire and environmental risks, and be safe throughout its lifecycle.

The acoustic performance of the Trimapanel® flat system has been predicted using software developed by the Department of Applied Acoustics, University of Salford, under a research contract funded by the Metal Cladding and Roofing Manufacturers Association (MCRMA). The results below are based on a 70mm core.
