blast resistance

the expert in structural blast security contact us

If a risk analysis highlights a risk of explosion, it goes without saying that precautions will need to be taken. Finding a balance between organisational, electronic and structural measures is essential here. The importance of the structural security category is sometimes underestimated, however, even though such measures can prevent people sustaining injuries in an explosion and limit the damage caused to buildings and goods. aalbers|wico is the expert in the field of structural blast resistance. We manufacture, supply and install all blast-resistant products precisely in accordance with the applicable 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 products on paper - we test it in practice too, in our own test centre. Here we check whether the products 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).


Our products 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 solution offering the actual level of resistance you need. The official standards form the starting point here, but the products undergo further testing on the basis of additional criteria.

testing methods

In our test centre we can examine the resistance of products 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 blast-resistant products 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.
