the expert in blast-resistant doors
The purpose of a door is to give you access to a room. From a security perspective, however, that is also its weakness. In the event of an explosion, doors form a vulnerable part of a building's structure. Do you want to make sure your door keeps out any damage from an explosion? Why not contact aalbers|wico - the specialist in structural blast security! We manufacture, supply and install blast-resistant doors precisely in accordance with your specifications. If you wish, they can also be offered in combination with intruder-, ballistic- and fire-resistant properties.
tested in practice
We not only calculate the resistance level of our blast-resistant doors on paper - we test it in practice too, in our own test centre. Here we check whether the doors meet the required level of mechanical resistance (as described in the European standards) or the desired level of protection (as specified in the US GSA standard).
standards
Our doors are based on standards such as EN 13123, 13124 and 13541, the US GSA guidelines, and ISO 16933 and 16943, but we can also go one step further. If stipulated in the Schedule of Requirements, we can supply a door offering the actual level of resistance you need. The official standards form the starting point here, but the door undergoes further testing on the basis of additional criteria.

testing methods
In our test centre we can examine the resistance of a door under virtually all conditions using realistic tests. This is possible as we have the space to carry out open field tests and our facilities also include a shock tube.

resistance classes
During field tests and shock tube tests, the resistance class of a blast-resistant door is defined on the basis of various factors: these include the weight of the explosive, the distance at which the explosion takes place, the peak pressure, impulse and duration of the pulse of the explosion and whether there is any splintering.
