RAL – Quality hallmark

Walraven is a founding member of ‘Gütegemeinschaft Röhrbefestigung’ (Safe Connection). As part of this association, along with other producers of pipe clamps fixing systems, we have set up unequivocal product quality guidelines. The ‘Gütegemeinschaft Rohrbefestigung’ has become acknowledged in 2003 by RAL, the German institute for quality guarantees.  Over time, RAL has become established as the recognised body charged with the certification of products and services.

Certification is recognised by means of a quality mark; this is highly regarded by consumers and the wider economy alike, because products and services awarded the quality mark guarantee a high standard of tested quality.

Here is a very short video explaining what RAL quality marks are:

RAL quality mark for fire tested supports

The ‘fire-tested pipe support’ quality mark (RAL-GZ-656) is important because although steel does not burn, it can fail in the event of fire. This RAL mark is awarded to products that completely satisfy the high requirements expected of fire-tested pipe clamps and supports.
