Icons and Symbols guide

Across this website, as in our catalogues and leaflets, you will find several symbols, graphics and icons which are meant to help you choose the best product for your application. Most of these symbols are standardised for the building sector and related activities but we know that there's a lot to cover and we want to make it easier for you. In this section you will find their explanations.

Note that you'll be able to choose your products according to your needs and usages. As a global company we cover things from international standards like the European Technical Approvals to national approvals and certificates. We also include our own markings as manufacturers for a full understanding of our offering.
