Materials shall be sufficiently robust and durable to withstand normal working conditions. Additional requirements for some materials are given in EN 12811-2.
When materials are used, whose properties in relation to the intended application (e.g. temperature, ageing. UV-degradation) are not given in any available standard an adequate assessment is required. Steel shall be protected by one of the methods given in EN 12811-2. or zinc plated to the level required for the design service environment stated in EN ISO 2081.
