Our mentality.

Contact us

Delivering quality is always our priority, which is why our products and processes meet standards and hold certifications. We design according to all standardized building codes.

Quality control

We have a production-independent quality control department. Prior to production, we determine what tests and inspections are needed according to the construction standard and to meet your requirements. Our quality control department performs inspections and partial tests during production. At the final acceptance of a tank, you are invited to be present at the final checks performed by our quality control staff. We are provided with all the equipment for performing various quality tests:

  • Riboflavin test
  • X-ray
  • Penetrant test
  • Visual welding inspection
  • Drain test
  • Pressure test/full-of water test
  • Roughness measurement
  • Vacuum box test
  • Thickness measurement

Gpi is VCA** certified for the installation of stainless steel (pressure containing) tanks, fittings and installations. Our qualified installation department works according to strict procedures and instructions that are regularly checked by Lloyd's Register.



We are happy to cooperate if you wish to have additional tests and checks performed by a third party yourself. You are welcome to have an audit at our locations so that you can experience our quality for yourself. In addition, we support you in conducting ongoing periodic tests throughout the life of your installations.

Permits and Regulations

It is important for you to make a good inventory beforehand of the requirements your installation and tank must meet. When issuing permits, the government may refer to various norms and standards, such as PGS 29, 30 & 31 and EN 14015 and EN 13445. Our experts are familiar with these regulations and can provide you with professional advice for obtaining your permit. In addition, we can support you during discussions with government agencies if necessary.
