Blast resistant walls

The bolted or welded wallpanel system 'IDM ProPanel' secures the safety of your environment. Lightweight wall systems of all fire ratings with blast rating if required.

A blast wall can be regarded as a firewall for which an additional functional requirement applies, i.e. that apart from the usual wind loading, the wall needs to be able to resist a certain blast overpressure. As a consequence the IDM Propanel and the IDM Panel Welded, in principle can be considered as a blast wall. To extend the favourable characteristics of our IDM-Propanel  systems to blast wall applications with large spans and higher blast loads, a hybrid shape has been developed comprising columns integrated in the wall system at a relatively short spacing (2.0 - 3.0 metre), to carry the blast loads transferred from IDM-Propanel infill panels. In this hybrid shape a discrimination has been made between the load bearing function (hot rolled carbon steel columns) and the separating function, i.e. the infill panels. This 'best of both worlds' solution takes advantage of both the favourable high strength characteristics of hot rolled sections and the light weight, separating and insulating properties of the walls. Especially for walls that are required to have a stainless teel external skin this blast wall is a very competitive structure.

Jet Fire

Just as blast a jet fire resistance specified for a wall can be regarded merely as an additional functional requirement. Therefore basically all our wall systems can be considered in this respect. Jet fires are characterized by a local concentrated heat input that is more severe that the effect of a hydrocarbon fire.
