Abstract

Modular sheds coverd with technical membranes are a more economically interesting solution considering conventional masonry constructions and heavy metal structures. The selection of technical membranes for shed coverings can and should go through important analyses, depending on their application, with two main applications being modular sheds, sides and roofs. The fabrication of the membranes considers not only the soldering tool but also the distance between the columns and the distance from the axis of the aluminum anchorage profile and the keder. The membrane mechanical analyzes have specific standards and compliance with these standards will ensure the best choice of material for the intended application.
