Company description
The J. van Walraven BV was founded in 1942 and is a privately held company. We develop, produce and distribute innovative fastening, fire protection and plumbing systems. Currently, the Walraven Group consists of the holding company and 18 other subsidiaries.
Organization of the group

Product systems
Our range is clearly divided into three areas:

BIS fastening systems
And much more fixing materials for heating, ventilation and sanitary installations as well as for sprinkler pipes, air ducts, electrical cables, cable trays

BIS Fire Protection Systems
Solutions for fire resistant and smoke gas-tight sealing of pipe and cable penetrations. As well as fire protection certified support products.

BIS Sanitary Systems
Sanitary pretext frame for fixing of toilet bowls, urinals and washbasins. Special BIS Vario ®: Electric or mechanical height adjustment!
Ultimately Sanitary Silicones and Sealants ...

Distribution
In Europe, and particularly in Germany Walraven has a huge market share in the attachment area.Walraven products are used by thousands of installation companies in Europe, America, Asia, Australia and the Middle East.

Safe Connection
Walraven is one of the founders and member of the 'European Quality Association for pipe mounting eV' (safe connection). The composite consisting of numerous major manufacturers of
Pipe fixing market, has established comparable, transparent policies regarding the testing procedures of load values.

Advantage for planners and craftsmen: a more reliable and easier planning.
The 'Quality Association pipe fixing' was 2003 eV from the "RAL", the German Institute for Quality Assurance and Certification, recognized.
Quality labeling
J. van Walraven Holding BV is ISO 9001; 2000 certified

Production
After 71 years of experience in the production of pipe fastening systems, Walraven can look at a tool and machine park, which is located at the highest technical level, and thus allows absolutely competitive production processes..
Production includes cutting, shaping and cutting of sheet metal and metals. A fully automated rail manufacturing to galvanizing and automatic packaging.
Bzgl. Metal Stamping: Here we have more than 30 different presses with different benefits (force values ​​45-130 tons and speed between 20 and 150 ejections per minute). Ultimately Walraven can look back with pride on its own and full grown continuously tool shop, so that developments always even, safe and fast can be implemented.
