What it is about
A certificate is not a goal. It is the proof that we do what we promise.
The four certificates
Audited by independent bodies.
Scroll and the certificates come down one by one.

VCA-Petrochemie
Safety first, always and everywhere.
The strictest safety standard for contractors in oil, gas and chemicals. Our crews work to strict safety standards to limit risks and prevent incidents.

ISO 9001
Quality in every step of the process.
A globally recognised quality management system, so every project meets the strictest requirements and we keep improving.

ISO 3834-2
Excellent quality, documented.
Welding that meets the strictest quality requirements, with durability and strength as the starting point.

EN 1090
Steel structures to the European standard.
The European standard for steel and aluminium structures. Every structure we build meets it and receives CE marking.
What it gives you
Less checking on your side.
With the certificates in the file, you have less to verify yourself.
Access to every plant
On most sites in the Rijnmond area, VCA-Petrochemie is the requirement for being allowed to work at all.
A file that is right
ISO 3834-2 and EN 1090 mean that welding and structures are documented and inspected.
Periodic audits
The certificates are regularly audited by independent bodies. That way it does not stay on paper.
