Certifications

There are different levels of quality when talking about aluminium trusses. There is the quality of the raw material, the quality of welding and the quality on the manufacturing process. Products have to comply with all the relevant international standards and they are tested and certifi ed by the most respectable certifi cation institutes. High quality equals safety. This is guaranteed not only through certifi - cates, but also with common sense and deep knowledge of engineers and installers. The product needs to be calculated and certifi ed through rigorous calculation reports and installation must be tested by a qualifi ed engineer.

The Standards that are commonly used for the technical evaluation of a product refer to normative codes issued and recognized at a national and international level. Among these we can mention ANSI, BS, EN, ISO, DIN. Each of these outlines a diff erent calculation approach, still leading to similar results.
