the expert in blast-resistant entrances
For many companies and institutions, the entrance to their premises reflects the image of their organisation, meaning it has to be welcoming.
Sometimes, however, the entrance also needs to provide protection against attacks or robberies.
As the specialist in structural blast security, aalbers|wico can help you combine these two functions.
We manufacture, supply and install all the components needed to create a blast-resistant entrance.
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 entrances on paper - we test it in practice too, in our own test centre. Here we check whether the components 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 entrances 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 entrance offering the actual level of resistance you need. The official standards form the starting point here, but the entrance undergoes further testing on the basis of additional criteria.

testing methods
In our test centre we can examine the resistance of a entrance 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 entrance 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.
