Case Antoni van Leeuwenhoek Hospital

  • Antoni van Leeuwenhoek Hospital is the number one cancer hospital in the Netherlands and one of ten comprehensive cancer centers in Europe.
  • To ensure that the MRI scanner functions flawlessly, Outokumpu supplied non-magnetic stainless steel reinforcement bar to construct a new floor in the hospital.
  • Located in Amsterdam, the Netherlands

Stainless for sensitive surroundings

The western outskirts of Amsterdam host the Netherlands’ leading oncology center: the Antoni van Leeuwenhoek Hospital. Named after the ‘father of microbiology’, who in the seventeenth century made ground-breaking improvements to the microscope, this hospital is both a cancer research center and a clinic. So innovation is key to ensure the best treatments for patients. As such, for the renovation of the MRI (Magnetic Resonance Imaging) scanner room, the hospital looked for an efficient and durable way to construct the floor so that the reinforcement bars (rebar) won’t disrupt the magnetic-sensitive scanner.

A non-magnetic floor

Everything within a zone of 85 centimeters around the machine has to be non-magnetic, including the floor and its rebar. As for the rest of the floor, standard carbon steel bar would do the trick.

In order for this core part of the space to be free of any magnetism, engineer Jan van Vliet, the Director of J. van Vliet Vlechtwerken, was asked to provide a solution. “I didn’t have to think long,” he says. “I asked Outokumpu to provide non-magnetic steel rebar in quality Core 304LN/4311.” These rebar are stainless, which ensures low maintenance and low risk of carbonation. Outokumpu brought the hospital a very sustainable floor – which is much more appealing than the traditional method of using lead plates to cover the floor.

Perfect combination

Outokumpu supplied non-magnetic stainless rebar in 10 and 12mm diameter. Weighing a total of nine tonnes, the floor of the room in the Antoni van Leeuwenhoek Hospital contains 1.5 tonnes of Outokumpu rebar. Outokumpu already pre-cut and bent the rebar prior to delivering them to the hospital.

After the concrete was cast, the end result was one solid floor – ready to support the hospital’s vital machine that detects cancer: the MRI scanner.

Case facts

Challenge

Constructing a solid floor with non-magnetic material of which the MRI scanner will be placed, plus a zone of 85 centimeters around it. 

Solution

The concrete floor is reinforced with Outokumpu’s non-magnetic, austenitic Core stainless steel.

Delivery
