Wall steel beams - is that useful?

Again and again questions arise on how best to build a steel girder. Whether this makes sense at all, which other (simpler possibilities) there are, and what you should pay attention to when walling out, you will learn in this post.

Wall or not?

Basically, disguising a steel girder is much easier than bricking. In any case, you have to keep in mind that the lining should also be stable - and that is not always easy.

Fire protection

In addition, fire protection regulations come into play in many cases. A steel beam that performs a static function must be protected against heat. Otherwise, it can happen that the high temperatures in a fire in the interior reduce the carrying capacity of a steel girder so far that the building can at least partially collapse due to the fire.

Even at temperatures of around 100° C, the load-bearing capacity of a steel girder is already measurably reduced, and in fires even higher temperatures can be achieved.

In the case of valid fire protection requirements, a specific fire protection class is prescribed for the wearer, which must be adhered to. This is only possible with appropriate, special plasterboard (GKF) in the appropriate version.

finished parts

A cladding of a steel beam is also easier insofar as there are matching finished parts for each carrier in plasterboard cladding, including a matching metal substructure. Such finished systems are very easy to use, in addition, the plastering of plasterboard is much easier than the production of a cleanable surface on a bricked support.

Alternative Rabitz construction

Also so-called Rabitzkonstruktionen, as they are used for the production of a plaster of steel beams or vaults, may be a possibility. Individual designs also have very good and often adequate fire protection values.

When walling in any case note

Anyone who would like to wall it anyway, should pay attention to a good adhesion of the masonry. It is important to adequately prime the backing and, in any case, provide additional rust protection on the backing. The subsequent plastering then takes place in any case by attaching an expanded metal mesh, so that the plaster also adheres well to the support surfaces and does not dissolve during movements of the wearer (temperature changes).

Tips & Tricks

If a wearer is warm and in contact with cold components, he should be isolated. This is best done with loose rockwool, which additionally fulfills a fire protection function. Styrofoam should not be used if possible.
