Additional significant anti-corrosion protection and a perfect match to the RAL/NCS color. UV stabilizers ensure color consistency even after several years, and the modern Powder.coat powder coating technology ensures the coating's durability during installation and a long service life.

2. EPDM washer

Made of the best sealing material - EPDM. It does not lose elasticity over time and has a very long aging period. Resistant to changing weather conditions and UV radiation. After installation, it self-vulcanizes to the sheet metal, creating a tight connection.

3. Hexagonal head with marking

The hexagonal head ensures easy and secure screw installation, which significantly simplifies work and increases installation efficiency. The distinctive marking of ETANCO products allows for easy identification; each production batch receives a unique number, enabling precise identification.

4. Thread under the screw head

The additional thread with an increased diameter ensures proper distribution of the EPDM washer on the thin cladding sheets of the sandwich panel.

5. GREY.COAT ceramic coating

Provides the highest protection against corrosion while maintaining excellent drilling ability. This allows them to be used in demanding conditions, such as a class C4 corrosive environment.

6. Self-drilling tip

Significantly improves the installation process by eliminating the need for pre-drilling holes. GTR 12 screws can handle steel up to 12mm thick.
