A Colorcoat® pre-finished steel product from Tata Steel is one that has undergone many years of development and optimisation
Each of the individual elements which make up the pre-finished steel product is specially selected to give optimum performance and to work together so that the final product is much greater than the sum of its parts.
Each product is made up of:
In order to adhere an organic paint coat to the metallic surface of the substrate, a thin layer of pre-treatment is used to modify the chemical nature of the surface and provide a ‘key’ for the paint. All elements within a pre-finished steel product are equally important including the pre-treatment.
The best primer and topcoat available are ineffective unless their adhesion to the substrate is ensured for the product’s lifetime by a suitable pre-treatment. All Colorcoat® products have a controlled and consistent pre-treatment.
Most coatings for external applications consist of at least two coats, a primer and topcoat. The function of the primer is to give corrosion protection and optimal adhesion to the substrate. Through 50 years experience in the development and manufacture of Colorcoat® products, Tata Steel has developed the most advanced primers tailored to give maximum protection to the substrate.
Metallic coated steel substrate
The basis of any pre-finished steel product is the steel itself. Steel is generally produced to national or international standards and it is important to ensure that the mechanical properties are those required. For roof and wall cladding products, this is generally considered by the system manufacturer in producing load/span tables.
In terms of the durability of the product, however, it is the coating of the steel substrate which has an effect on lifespan. The type and quality of the metallic coating is often a detail that is overlooked when considering a durable pre-finished steel product. However, significant performance differences do occur.
Tata Steel supplies pre-finished steel products with metallic coatings of hot-dip galvanised (HDG, nominally 99% zinc) and Galvalloy® metallic coating. The metallic coating for Colorcoat HPS200 Ultra® and Colorcoat Prisma® is Galvalloy®.
HDG is the standard substrate for the majority of pre-finished steel products and also provides the basis of the majority of un-painted steel used in the construction industry, for example, light steel framing. The zinc coating on HDG preferentially corrodes rather than the steel, so the onset of rust at exposed edges and surfaces is delayed, in some cases indefinitely.
Galvalloy® is a metallic coating which consists of 95% zinc and 5% aluminium, and manufactured by Tata Steel under unique process parameters to have optimum corrosion resistance. Galvalloy® is used on the branded pre-finished steel products in the Colorcoat® range to provide the ultimate corrosion resistance, particularly at the cut edges often encountered on roof and wall cladding systems.
The key elements of the organic (paint) coating are polymers and pigments. The polymers, also referred to as resins or binder, are organic-based carriers that chemically surround pigment particles and provide the basis of the continuous organic coating. Pigments are insoluble materials which are dispersed within the polymer to provide colour, opacity and other visual effects as well as corrosion protection.
In the topcoat, pigments are most frequently used for aesthetic reasons. A number of polymer resins can be used to make the topcoat. The polymer chemistry, pigment type and other elements of a paint formulation can have a significant effect on properties.
The Colorcoat® brand is recognised as the exclusive Tata Steel mark of quality and metal envelope expertise. Colorcoat® products are supported by a comprehensive range of services, technical advice and guidance.

Colorcoat® Centre for the Building Envelope
Working with one of the largest architectural schools in the UK, Tata Steel has established the Tata Steel Colorcoat® Centre for the Building Envelope at Oxford Brookes University to support research and innovation in the use of pre-finished steel in the building envelope.
The centre will help Tata Steel provide increased assistance for our customers in developing new cladding systems and conduct research to promote the use of pre-finished steel roof and wall cladding systems in the buildings of the future. A key area of focus is how the building envelope can contribute to the aims of sustainable development, with work focusing on minimising operational energy as well as life cycle analysis and the development of modern methods of construction. One example of this work is the extensive programme of physical testing which has been carried out on the air-tightness of cladding joints. The Colorcoat® Centre provides an excellent example of how Tata Steel is working to provide better value for the market.
Development of testing facilities to assess air-tightness
The Tata Steel Colorcoat® Centre for the Building Envelope, based in Oxford, has developed one of the world’s most advanced testing facilities for assessing the air-tightness of building details. Using this it is possible to simulate real life detailing issues and determine the effect on whole building air-tightness. This will be Invaluable in helping architects and contractors comply with the changes to Part L (2006) Building regulations. In developing these testing facilities with Oxford Brookes Architectural School, Tata Steel believes the results will be used to provide more airtight building details, reducing energy-in-use for the client and future-proofing commercial developments from uncertain fuel prices. Results of this study can be found in the Colorcoat® Technical Paper "Creating an air-tight building envelope".
