New investments in 2016
The workshop built in 2013 had become too small and was expanded by 1700 m2 in 2016, to be completed around the new year 2017. The new extension is suitable for the vertical construction of vessels and is also equipped with a new pickling hall. As regards machinery, too, new investments were made: among other things, the new Plasma Keyhole installation is the perfect complement to the impressive investment programme implemented in 2013.
Recent technology and enthusiastic professionals
At Deprest, all major production equipment dates from 2013 or later. Your projects are therefore executed with the latest technology, with a positive impact on quality. But the most important thing is still the knowledge and experience of Deprest and our people. Deprest boasts 80 years of experience, and a number of experts from G&G International and Inalco who also joined our ranks recently.

Our trump cards
- Use of most recent technology
- A team of experienced persons
- Vicinity of the port of Antwerp and hence the possibility to carry exceptional loads both by road and water networks
- Focus on quality (separate stainless steel processing, operating to various standards)
- The flexibility and drive that characterize SMEs
The latest technology and enthusiastic specialists
All major machines in the Deprest site date from 2013 or later, meaning that your projects are being executed with the aid of cutting-edge technology, which results in better quality products. But most significant are still the skills and the experience of Deprest and our employees. Deprest can look back on 80 years of experience, and on the recent reinforcement with experts coming from G&G International and Inalco.
Transport by ship or truck
The location of Deprest is particularly suited to exceptional transport by ship or truck
Close to the highway and the port of Antwerp , Deprest can easily use exceptional transport. Deprest can rely on plenty of external partners for that purpose.
Deprest is located a few hundred metres from the River Scheldt in Temse, on the site of the former Boelwerf shipyard. The river is deep enough to allow the transport of any cargo size.
Deprest is equipped to produce pressure vessels up to 85 tons, with a maximum diameter of 8,5 metres (the size of our largest gate is 9m x 9m).
Deprest chooses quality:
- ISO certified according to ISO 9001:2008, as well as according to the ISO 3834-2/BS welding standard
- Structures work according to the various standards and codes
- Broad expertise with regard to calculation and design
- Practices separation of stainless steel and steel during production
- Works with state-of-the-art machinery
- And very competent, experienced people
- Extensive know-how in post-treatments and finishes
Welding job of thick sheets - up to 100 and 200 mm
While most of the welds laid in our workshop are between 6 to 10 mm and 20 to 30 mm, some welds are well above that. We can also weld plate thicknesses from 150 to as much as 200 mm. If a continuous weld is required, it goes without saying that a great many welding layers are necessary.
We can never afford mistakes, so you understand that the quality of the welds is all the more important. Imagine that RX testing performed on such a welded joint reveals welding defects deep inside...
New! Plasma keyhole welding derrick
Our new plasma keyhole welding derrick has been installed and initial tests look promising!
The welding derrick uses the same technology as our existing plasma keyhole welding installation, but has an automatic clamping system with integrated backing and cooling so that a flat or centred plate no longer needs to be spot welded, and just needs to be clamped together before welding.
Flat sheets thus remain straight and flat during welding; the machine produces a perfect continuous weld (for stainless steel, within a range of 2 to 10 mm) in one single pass and works at a very high speed.
In the autumn Deprest contributed to an artistic project, which consisted in an aluminium structure for a major show.
The structure involved one large central ring with a diameter of 8 metres and 4 hinged metal legs.
Watch the video to get a good feel of what went on in our workshop. It also demonstrates how the articulations of the structure were tested.
Another pressure vessel has left the building
It’s not suprising to see a pressure vessel leaving Deprest. We at Deprest are specialized in pressure vessel. Each week some vessels – large or small – leave the site. Our pressure vessels are made in steel, stainless steel and special alloys. We elaborate and follow projects from A to Z, inclusive technical calculations, design, testing, complete execution, and the testing and follow-up of the necessary inspections.
Deprest has spent several years installing cutting-edge technology and equipment.
Ever since 2013 when we added a new building, we have equipped ourselves with the latest technology in the areas of cutting, rolling and welding, and our new building has even been extended because it was too small. Notwithstanding all this new technology, we wouldn’t have gotten where we are without skilled professionals.
