Client: Travis Perkins plc
Architect: Bate and Taylor Architects
Principal contractor: Barnwood Construction

Key drivers in selecting a pre-finished steel cladding for the steel-framed Wickes store at Cirencester was guaranteed system performance and sustainability. The client, Travis Perkins, specified Tata Steel branded products to meet the design and performance criteria.
Travis Perkins has worked with Tata Steel as its partner of choice in an ongoing store construction programme. Again at, Cirencester, it was Tata Steel they turned to to help them meet the need for a bespoke and high-quality building envelope with guaranteed performance.
To support Wickes’ brand identity, a pre-finished steel in a non-standard colour was supplied and experts at Tata Steel supported the project with solutions and advice on structural and thermal performance, bespoke fixings and maximisation of BREEAM credits.
Travis Perkins invested £3.5M in the development of the Travis Perkins Trade Park at Cirencester, Gloucestershire. The company invested a further £1M in its new Wickes Trade and DIY Store at the park. To protect the investment in this 20,000 square foot store, a comprehensive guarantee covering the long-term performance of the store’s building envelope was required.
In addition to structural and fire performance, a certain level of thermal performance was required. Whole life cost considerations demanded a building envelope with little or no inspection and maintenance requirement.
A sustainable building envelope was high on the list of requirements. Evidence of responsible sourcing was required, alongwith environmental product declarations (EPDs) for all pre-finished steel cladding components. Maximisation of BREEAM credits was an important consideration.
Travis Perkins’ branding requirements demanded a pre-finished steel solution which could be supplied in a specified RAL colour. Local planning regulations also reinforced the need for a flexible building envelope system with scope for incorporation of a design feature using timber.
The building is clad with Trisomet® and Trimapanel® insulated panels with super durable Colorcoat HPS200 Ultra® pre-finished steel used predominantly on the weather side. Tata Steel provided a tailored Platinum® Plus system guarantee covering performance of the complete building envelope. The versatility of Trisomet® allowed the building to be part-clad in timber to meet local planning requirements.
The client specified Colorcoat HPS200 Ultra® and Colorcoat Prisma® pre-finished steel for the weather side of the building.. This pre-finished steel was used in the manufacture of Tata Steel’s Trisomet® insulated roof and wall panel system and Trimapanel® insulated wall-cladding system. The Cirencester store incorporates 140m2 of Trimapanel® 90mm insulated wall-cladding with Colorcoat Prisma® pre-finished steel on the weather side in a colour developed specifically for the client.
“Tata Steel provides a better guarantee on its branded products compared with other panel systems on the market. We are confident that if anything were to go wrong with the building envelope, Tata Steel would put it right.” Travis Perkins
Close working with the client and architects meant we were able to develop a bespoke Platinum® Plus system guarantee covering performance of the complete building envelope. The guarantee specification considers the interactions of envelope components and how they impact building design and performance. The high-quality Colorcoat HPS200 Ultra® and Colorcoat Prisma® pre-finished steel products are themselves backed by our Confidex® Guarantee which offers cover for up to 40 years.
Colorcoat HPS200 Ultra® combines outstanding performance with exceptional durability. Subjected to natural and accelerated testing, it delivers proven high levels of corrosion resistance along with colour and gloss retention. The Wickes store at Cirencester uses more than 3,000m2 of Colorcoat HPS200 Ultra® pre-finished steel on the walls. This was supplied in three toning colours to satisfy branding and aesthetic considerations – ‘White’, ‘Svelte Grey’ and ‘Honesty’. A further 4,200m2of Colorcoat HPS200 Ultra®, in ‘Goosewing Grey’, was used with Trisomet® 120mm insulated roof panel system in a bespoke roofing solution.
The roofing system was supplied in very long lengths to span 19 metres. This minimised end laps to provide air tightness and helped ensure the building’s required thermal performance. In addition, the bespoke lengths minimised the number of roofing components for a fast and efficient build.
