    Solar Reflectivity

    Bridger Steel Color Solar Reflective Values

    Understanding how a construction material like metal roofing or siding will interact with the sun can help a building prepare for weather conditions, minimize heating or cooling costs, and reduce heat island effects in urban areas.  There are (3) main figures to understand when choosing a color: TSR, E, and SRI values.

    Total Solar Reflectance (TSR)

    TSR or Total Solar Reflectance is a figure expressed as a percentage between 0 and 100% that rates a products ability to reflect solar energy back into the atmosphere.  This includes visible, infrared and ultra-violet wavelengths. ASTM C-1549 or ASTM E-903.

    Infrared Emittance (E)

    Infrared Emittance (also referred to as Thermal Emittance) is rated between 0 and 1 and rates the ability of a product to cool itself by releasing thermal radiation back into the atmosphere. Painted finishes often maintain a lower emittance value than bare metal products.

    Solar Reflective Index (SRI)

    The Solar Reflective Index (SRI) combines the TSR and E value of a product (TSR x E). The SRI is scaled from 0 (standard black) to 100 (standard white). This index is often used by paint manufacturers as the primary measurement of a product's reflectivity.

    The following are the latest figures related to standard Bridger Steel colors & finishes:

    A606 Truten® Details

    Bridger Steel uses a proprietary variation of traditional weathering steel called A606 Truten®.  Designed specifically for light gauge engineered panel systems, A606 Truten® is a naturally weathering product and can be used in roofing and facade applications.

    Weathering steel, often referred to by the trademark Corten steel, is a group of steel alloys originally created to eliminate the need for painting structures like bridges or heavy steel structures exposed to the outside environment. As technology improved, use in residential and commercial projects drove interest in the light gauge market. 

    The original Corten received the standard designation A606 for thin sheet. All alloys are in common production and use.

    The surface oxidation of weathering steel varies greatly based on environmental influences, but surface treatments can accelerate the oxidation to as little as two hours.

    Bonderized Details

    Bridger Steel's Bonderized is a galvanized steel that is processed through a phosphate bath, which then has a layer of Chromate applied and dried to the coating.  The process produces a matte grey finish.  This finish provides an excellent surface for applying primer, making Bonderized an excellent option for applying custom or branded paint colors post-installation.  Paint should be applied immediately after installation to prevent the phosphate coating from developing white rust.
