Work done in 1995, which consisted of removing the existing iron railings aluminum railings, around a block of flats in the Avenida Diagonal in Barcelona. Thanks to a previously installed on the scaffold could facade easy access to removing the old rails. Anchored by chemical and asparagus taco stainless steel floor, new railings were installed in a couple of weeks. The reason for replacing iron railings usually aluminum maintenance, iron require periodic maintenance aluminum while requiring no maintenance. Are no problem for the facade of the building, as the anchors of iron railings are of this material and eventually crack the walls due to rust. In the case of an aluminum rail, the anchoring is done in cue aforementioned chemical and stainless steel stud, which is no problem to the facade. We can increase the rigidity of the aluminum structure by adding more or less clamping bases as appropriate. Consult no obligation on any questions, I will be happy.
