Chemical and water resistance of structural profiles

Chemical and water resistance of structural profiles

The Chemical and Water Resistance Table below shows resistance performance for three qualities of Fiberline profile in different chemical environments. The values indicate the highest known operational temperatures in °C at which the profiles have displayed good service life in the specific chemical environments. The results have been obtained from either industrial experience or from laboratory tests (ASTM C581) carried out by Fiberline suppliers.
 
Resistance to chemicals and water is dependent on concentration and temperature.
 
It is possible to use gratings, planks and structural supports in chemical environments specified as NR (Not Recommended) or at higher temperatures than stated, provided the chemical influence is not permanent or concentrated but short-term or weak (such as from fumes or spillage).
 
In contrast to metals, Fiberline structural profiles are not subject to electrolytic corrosion.
 
Please note that the values stated for chemical resistance are based on profiles with surface veils and with all machined surfaces sealed.
 
All data in the table are supplied in good faith and Fiberline accepts no liability for its accuracy.
 
Fiberline reserves the right to make changes without prior notice.
