Steel warehouses are frequently found in most varied productive industries. Having safe industrial facilities is a must, thus the related structural calculation becomes a long and tedious, though routine task. This fact makes it vital to have software that allows the calculation of symmetrical warehouses of double slope. This paper proposes a programmable method able to make routine calculations of structural elements in a single run, which are brief and yield good results from the techno-economic point of view. The fundamental contribution resides in the delivery of a tool in the field of applications software, powerful, fast and modeling in a way that a user without much experience in structural calculation or full knowledge of the structural norms of design, will be able to face the calculation of an industrial warehouse without difficulties.
