The racks will also be providing point loads instead of distributed loads.
Make sure the flooring is strong enough to hold the feet of the racks
without puncturing. In particular, the various manufactured wood products
(flake board, oriented strand board, particle board) can be punctured
easily.
An overlay of 3/4" plywood glued and screwed should provide the needed
support for the feets. If you use ACX grade and put the nice side up, you
can put down a simple floor finish and it looks nice too.
Avoid carpet (hard to move racks after they have sat for a while),
linoleum (dimples never go away), and soft woods (pine).

Camiel,
Usually 250Kg - 300Kg per m2. Your 500kg on that surface should not be
a problem, there is a large safety margin.
I used to have 6 H960 racks next to each other, with an average of 150Kg
on a concrete floor made of 'kanaalplaten'. Your floor is a reenforced
concrete poured type and an integral part of the walls when the house was
build (gietbouw box constructie, sorry for the Dutch here).
For comparison, the wooden floor in my garage is also designed for 250Kg
per m2, and you have seen how that has been made.

Zeg NEE tegen de 'slimme' meter.
One thing you should also consider is the weight
loading you are going
to
put on your attic, and how it is distributed, less your ceiling sag over
time.
Good point. I hadn't considered that. I figure it'll weigh around 500
kg alltogether. The surface area is 150 x 70 cm = 1,2 m2. That's 416
kg/m2. The floor is made out of concrete, and I'm putting it into a
corner of two load-bearing walls. I'll make a call to the housing
corporation to find out what the maximum load is.
