THERMAL CONDUCTIVITY TEST

A test was conducted by the Warsaw University of Technology to determine the heat conductivity coefficient for 2.5 mm-thick brackets made of GD 350 steel with Magnelis® ZM430 zinc coating, used in ventilated facades manufactured by AGS.

No.	2.5 mm thick brackets made of GD 350 steel, with Magnelis ZM 430 zinc coating	^ mean value from test series [W/m*K]
1	170x50x70 bracket	3.906
2	210x50x70 bracket	3.537
3	170x50x130 bracket	6.615
4	170x50x130 bracket	6.422

Key findings

Table: Summary of calculation results for average conductivity coefficient for a 2.5 mm thick bracket made of GD 350 steel, with Magnelis® ZM 430 zinc coating.

The numerical results conclude that AGS system successfully obtained brackets of low heat conductivity coefficient through the openwork profile structure that extends the heat path.

Results

Testing resistance to neutral salt spray showed that ZM430 zinc-magnesium coating can effectively protect red corrosion on sheet metal surfaces after 1500 hours of exposure
Testing resistance to humid atmosphere showed that it can protect corrosion on sheet metal surface even after 15 cycles of exposure.
The AGS steel substructure with ZM310 zinc-magnesium coating can be used in an environment of the C5 corrosion category.
