Thermal Conductivity Certification

Introduction

At AGS Systems, we pride ourselves on our commitment to quality and innovation. As part of our continuous efforts to ensure the highest standards in our products, we recently collaborated with the Warsaw University of Technology to conduct a comprehensive thermal conductivity test. This test was specifically designed to determine the heat conductivity coefficient of our 2.5 mm-thick brackets made of GD 350 steel with a Magnelis® ZM430 zinc coating. These brackets are integral components of the ventilated facades we manufacture.

The Importance of Thermal Conductivity

Thermal conductivity is a measure of a material’s ability to conduct heat. In the construction industry, understanding the thermal properties of materials is crucial. It helps in ensuring that buildings remain energy-efficient, comfortable, and safe. By optimising the thermal properties of our products, we aim to provide our clients with solutions that not only meet but exceed industry standards.

Test Methodology

The test focused on evaluating the heat conductivity coefficient of our brackets. The specifics of the test are as follows:

  • Material Tested: 2.5 mm thick brackets made of GD 350 steel, coated with Magnelis ZM 430 zinc.
  • Test Environment: The test was conducted under controlled conditions to ensure accuracy and repeatability.

Test Results

Our findings from the test series are tabulated below:

Bracket Dimensions Mean Value from Test Series (W/m*K)
170x50x70 3.906
210x50x70 3.537
170x50x130 6.615
170x50x130 6.422

Key findings

The results from our tests were enlightening:

  • Average Conductivity Coefficient: Our 2.5 mm thick bracket made of GD 350 steel, with Magnelis® ZM 430 zinc coating, showcased impressive thermal properties. The openwork profile structure of our brackets effectively extends the heat path, resulting in a low heat conductivity coefficient.

  • Resistance to Corrosion: Our tests also evaluated the resistance of the ZM430 zinc-magnesium coating against corrosion. The findings were promising:

    • The coating effectively protected against red corrosion on sheet metal surfaces even after 1500 hours of exposure to a neutral salt spray.
    • The coating showcased impressive resistance to humid atmospheres, protecting against corrosion even after 15 cycles of exposure.
    • The AGS steel substructure with the ZM310 zinc-magnesium coating is suitable for use in environments falling under the C5 corrosion category.
